Electricity Saving Tips For Homes And Offices

What is the difference between solar inverter and regular power inverter?

By on April 22, 2016

Power inverters or home UPS have been in use in India since quite some time. Thanks to frequent power cuts, home UPS or power inverter industry has done well in India. But with increasing interest in solar power and solar panels many people are thinking of using Solar Power to charge the batteries to save electricity drawn from the grid. Having heard of solar inverter, many people wonder if their existing inverter system is useful or not. In past, we at Bijli Bachao have got this question many times: what is the difference between solar inverter and regular inverter? With this article we would try to answer the question.

What is an inverter?

A power inverter or invert is a device that converts Direct Current (or DC) to Alternating Current (or AC) using transformers, switching and control circuits. And this is the basic function of any inverter: be it solar or regular inverter. A home UPS or home inverter take the DC power from the batteries and convert it to AC power used by appliances. A solar inverter also does the same if it is an “Off Grid” solar power system. In case of “Grid Connected” the DC power is from the solar panels and AC power is given to the grid. (To know more about “Off Grid” and “Grid Connected” solar power system, read our article: Solar electric, solar thermal, power generation, inverters, grid, off-grid: clearing the cobweb).

Working of a Home UPS/Inverter

A regular home UPS/inverter system has a system of inverter and batteries that is connected to the home power connection. When the power is coming from the grid, the UPS/inverter system charges the batteries using the power coming from the grid. When the power is off, the inverter takes the DC power from the batteries and converts it into AC used by appliances. There is an automated switch in the system that senses if the grid is not supplying power and switches the UPS into battery mode.

Working of a Off Grid Solar Powered system

An off grid solar powered system has an assembly of solar panels, charge controller, batteries and inverter as shown in the image below. The batteries are charged using solar panels and the inverter has the same function of converting DC to AC. It can also have an automated switch to sense if grid is not supplying power that can change the power source of the connected home from grid to batteries. Depending on the need the system can be designed to: 1) To completely rely on solar power 2) Charge the batteries from solar power when sun is available and from the grid when it is not.SolarInverter

An existing home UPS or Inverter system can be converted to be used with an off grid powered system by just adding a switch which can control the change source: solar or grid (based on availability).

Having said that, to answer the question posed in the title of this article: there is not much difference between a solar inverter used in off grid system and a regular inverter.

Working of a Grid Connected Solar Power System

A grid connected solar power system additionally supplies excess electricity to the grid. People go for this kind of system when they feel that they have enough space to install solar powered system and they can sell the extra electricity generated back to the electricity distribution company. The structure of a grid-connected system is shown below:GridConnected

The purpose of the inverter in this kind of system is also to convert DC (generated from Solar Panel) to AC. But it additionally needs a MPPT (Maximum Power Point Tracking) feature to be built in it. Because the voltage generated by Solar Panel varies depending on the temperature and availability of sun (more on this on our article: Solar Glossary – photovoltaic, panels, modules, cells, voltage, watt and current), MPPT enables solar inverters t draw maximum power from the solar panels. The solar inverter used for grid-connected solution also includes an anti-islanding functionality to prevent risks to grid in case there is power failure in the grid.

Conclusion

The basic purpose of any inverter is to convert DC power to AC power be it solar inverter or regular inverter. Depending on the situation and setup one may need some additional features, which can be implemented in existing home UPS/inverters through simple modifications.

Can I use my generator charge my battery when there is no sunlight

2
Abhishek Jain (Mod)

It would not be very economical. Because adding steps would lead to losses. Better use the electricity from generator directly rather than using it to charge the battery.

I am considering buying the LUMINOUS PREMIUM SOLAR HOME UPS 850VA KIT (150AH BATTERY + 300W SOLAR PANELS) from the online store - glowship. com. They are offering it for ₹39,500 (including installation). The solar panels though, are not Luminous, but a brand called 'Emmvee'.
I have a few questions:
1) Would you recommend buying it from a shop rather than an online store?
2) Is the brand of solar panels a good one?
3) Is the price quoted reasonable?
4) Is this a good choice as a back-up for 1 TV, 1 fan and 2-3 lights?

4

1. Considering buying online -price will be high
2.EMMVEE good one
3.refer point one
4.good choice

5
Abhishek Jain (Mod)

Hi Archana,

Glowship is an ecommerce startup company in Solar by IITians known to me. So certainly I do not have anything bad to say about them :) . Off-grid solar inverter is dominated by Indian brands, so Luminous is a good choice. As for Emmvee, it is a known Indian company (from Karnataka) working in solar since some time (it is one of the top big companies from India). The biggest ones are Vikaram and Warree (for solar panels). So to answer to your questions:

1) You may certainly buy online. Just make sure that they do the installation as well.

2) You can check the list of biggest companies on this link: https://www.bijlibachao.com/solar/top-ten-best-solar-panel-brands-manufacturers-india.html

3) An off grid inverter of 850VA should come for about 6-7K. Battery of 150Ah would come for about Rs 12000-15000 depending on type. 300 Wp solar panel should cost about Rs 12000-13000. So total comes around Rs 35-36K. But this is without installation. So price looks reasonable.

4) It can easily run 1 Fan, 2-3 lights and 1 TV. Your total wattage would be about 90+150+70 = 310 Watt. So 850 VA is more than enough. And in 150 Ah battery you can get easily up to 5 hrs backup.

I already have a 3KW Tie Grid Net metered connection at my residence. I am exploring the option of tapping some energy from the existing Panels directly to a Solar Hybrid UPS Inverter. The reason i would want to do this is, in Tie grid installation, solar power is isolated when there is power shutdown on the grid. Can you kindly educate me if I can tap the solar energy from the existing Solar Panels before they are fed into the Dynamo (tie grid inverter) ? Is this feasible and is it safe ?

My electricity bill was same even though with solar inverter... There was no change in my electricity bill ... How much does a LED Tv consume electricity from solar panel???

10
Abhishek Jain (Mod)

Typically LED TVs consume less than 100 Watts. A 100 Watts when used for 10 hours makes 1 unit or 1 kWh of electricity.

11

Hi, how to recognise whether the solar inverter is working using sunlight or it is working by using electricity from mains?

12
Abhishek Jain (Mod)

Do you have a solar inverter (one that just charges battery from solar) or a solar hybrid inverter (one that charges battery either from solar or mains)? In case of just solar inverter, there should be no electricity consumption from mains for charging the battery. A solar hybrid inverter should show when it is charging from solar and when from mains.

my name is augustine i want u to teach me how to install solar street light and solar inverter and power inverter

17

What should be the angle of the Solar Panels during Summer in Delhi????

18

If you plan to keep changing the angle throughout the year in accordance with the sun's position, then,
As Delhi comes above the tropic of cancer, and if u plan to have a fixed angle throughout the year, then the angle of the solar panel should be 28 degree (North to South alignment). This will make sure u will get maximum sun's rays throughout the year.
In summer, in Delhi, the angle should be 4 1/2 degree (theoretically). But its not advisable to keep changing the angle unless u have an automated system to track the sun's position.

for further queries contact [email protected]

19
Abhishek Jain (Mod)

You will have to check the same with an installer.

20

Dear Abhishek,

Thanks for the explanation! BUT what will happen when there will be power failure just after the drain-out of the battery? At that time we will be just out of any power back-up! There should be an alternative system so that when there is sufficient Solar Power from the PVs then it should be used directly through some DC to AC inverter so that batteries should not be used at that time & only be used when there is no electricity! Can you suggest something like that! Many Thanks - Gurdeep Gupta

21

I am using 500va normal inverter and connected 2fans and 2tublights and want to use su-kam solar convertion kit to use existing inverter as solar inverter.Now my question is if battery fully charged by sol con kit then it disconnect mains and supply through inverter to connected fans and tubelights.During this time remaining appliances will get power from mains or not(other fans,fridge,mixie,water pump etc) and anyother special wiring required further to existing inverter wiring to fans&tubelights. Please clarify.

22
Abhishek Jain (Mod)

All depends on how you do the wiring in your house. If you do not connect other appliances to the inverter, then they will not get impacted. Only those appliances that are connected to the inverter will get impacted by the conversion kit.

I have a Microtek Intelli Systems SEBz 1600. The per month consumption of my house is around 700 units per month. I for sure am looking for reducing the electorcity consumption and one of the options I thought of is the solar inverter / converter system. What I need to understand is what capacity of the solar inverter I should look for, what savings can I get from it on a monthly basis, what all do I need and what would it cost me?. Sunlight on my roof top is there for a min of 8 hours a day.

26

Dear Sanjay,
Solar system designing depends on your load, and the space available (Shadow free area) to mount the panels. So please provide your rooftop area, and the amount of power cuts in your area plus your location(State/City) and provide the Unit cost of electricity for the calculation of your savings.
Feel free to mail us at [email protected] or call us at 7307420111

A solar inverter converts the electricity from your solar panels into power that can be used by the plugs in your house for your TV, computer, and other wired products. Panels can't create AC power by themselves; they need the helping hand of a solar inverter.

An inverter is an electric apparatus that changes direct current to alternating current. It is not the same thing as an alternator, which converts mechanical energy into alternating current.

29

Dear sir
i want to know that can sukam solar con. kit of 24v-40Amp can run the home appliances in day dime along with charging the inverter battery with 1600 falcon+??i mean can i do both things at the same time with sol con kit?

30
Abhishek Jain (Mod)

As 12V Sukam sol conv kit can handle 320Wp panel. I guess a 24 V can handle double. So roughly 600-640 Wp panel. It should generate about 2.5-3 units of electricity in a day. You will have to check your electricity bill to see if that is sufficient to run all appliances in your house. It should work with your existing inverter. It charges the battery and extra energy can also be used to run home appliances.

31

my que. is not about how sol con. can handle the power i just want know that can sukam sol. con kit of 40Amp(pwm) can run the appliances at the same time when it charge the battery because i asked the sukam distributor he told me that it can only charged the battery.

32
Abhishek Jain (Mod)

Check this link: http://www.su-kam.com/power-solution/solar-packages/conversion-kit .... It says:

"During the day when solar power is being generated and and fully charging the batteries, Solarcon intelligently disconnects the mains and powers your house via inverter using energy stored in batteries. You take almost nothing from the main power supply which means your electricity meter stops – more savings for you.

When batteries are drained Solarcon first tries to get charged through solar but in absence of solar, goes on to mains mode and gets you power from main grid supply."

So it first tries to charge the battery. When the battery is charged it switches to the mains providing electricity to the appliances. The first objective is to charge the battery.

33

Dear Abhishek,

Thanks for the explanation! BUT what will happen when there will be power failure just after the drain-out of the battery? At that time we will be just out of any power back-up! There should be an alternative system so that when there is sufficient Solar Power from the PVs then it should be used directly through some DC to AC inverter so that batteries should not be used at that time & only be used when there is no electricity!

34
Abhishek Jain (Mod)

Most states in India now have a net metering policy wherein you can install a grid connected solar PV system. In a grid connected system you use power from solar if it is available and if you generate extra it gets sold to the grid. If you regularly generate extra, you earn money. And the best part of such a system is that you do not need any batteries. Whatever part of your consumption solar can provide, you use it, the rest is provided by Grid. If you generate extra it is sold. And in case of power cuts, you just use solar.

But for that your state should have net metering policy (which 17-20 states in India do have). Just check it out.

35

Thank you for information

36

I'm using Exide 850VA solar home ups with 300 watts panel, but the cooling fan is running 24 hours and consuming around 30 - 40 watts / hour. will it be like this or there is any problem in the solar inverter. please clarify

37
Abhishek Jain (Mod)

Hi,

You will have to call up the manufacturer/dealer and ask them to check it out.

38

Kerala government has announced inverter users to either upgrade to solar inverters or be ready for disconnection. Solar water heaters also will be mandatory for large houses. This is the Malayalam link of the news report: http://www.mangalam.com/print-edition/keralam/380660#sthash.3b3kQVQt.dpuf

Now, My query is: I've a Su-Kam Falcon Plus inverter. Is it possible to install solar panels as a add-on?

39
Abhishek Jain (Mod)

Falcon Plus is not a solar inverter. However you can always use Sukam's Solar Conversion Kit to convert your regular inverter to solar inverter. You can read more about it over here: https://www.bijlibachao.com/solar/solar-conversion-kit-a-better-way-to-use-existing-inverter-battery-system-with-solar-pv.html

40

Can i connect my microtek ups jm sw 2000 24v ac input main wires directly into my solar charge controller or are the main wires used only for main power not solar power plants help and thank u

41
Abhishek Jain (Mod)

You can use output of charge controller (which is Direct Current) directly to charge the batteries (if the batteries have the same voltage). You will not have to pass it through your regular inverter.

However if you want to use your existing inverter system with solar, then you should use a solar conversion kit along with your existing inverter system. You can read more about it on https://www.bijlibachao.com/solar/solar-conversion-kit-a-better-way-to-use-existing-inverter-battery-system-with-solar-pv.html

42

Thank u Jain and sorry for my late reply your reply helped me a lot and the link u sent did also I have another question why does my microtek upseb 2000 va 24v does not have a outer fuse I've seen photos online with fuses right under the reset button and thanks agin

43
Abhishek Jain (Mod)

Hi,

I am not sure on why your UPS does not have fuse. You may have to contact Microtek for that.

44

sir

I am having a regular/normal inverter with inverter battery connected with normal electricity connection . Now I want that battery should be charged through solar panels also in day time.
1 Can I add the solar panel to battery in the existing system???

2 of what spicefication of device (solar panel and solar charge) be used
3 when the battery is fully charged what about the cut off device
4 can i used the solar charge output supply without battery

45

Sir,
I wish to buy 600 W solar Panel ( for Exide 12V 850VA inverter). For best performance and efficiency 6X100 Watts or 3X200 Watts which is better or both are same in performance. Any advantages & disadvantages ?

46
Abhishek Jain (Mod)

Hi Rajesh,

I am not very sure, but most likely the performance should not be very different. However you may have to look at the voltage also. Each module gives 12 V. So if you put 3 in series it will be 36V, If you put 3 series of 2 in parallel then it will be 24 V. So you will also have to look at the voltage that you need. All of them in parallel will be 12 V.

47

Thank you

48

you should have to take 2 * 300Wp (16 Volt, Voc) modules, and connected them in parallel, it will give you the best results and less wiring also...

Dear Sir,
When I am searching online I found similarity in Eapro solar inverter and Exide solar inverter ie both are looking like same and specifications are also about same but only little price difference . My doubt is both are same or not. you can clear my doubt. please check link: http://www.eapro.in/solarhomeups.html http://www.amazon.in/Exide-Solar-Inverter-850va-Controller/dp/B00OBSZ49Y

51
Abhishek Jain (Mod)

Although Amazon has not given detailed technical specifications, but from whatever is available, both look similar. I hope you are comparing 850 VA models from EAPRO.

52

One of my friends using LUMINOUS inverter and he told me its working perfectly so I went to buy 850W inverter. When I went to shop salesman told me EXIDE inverter is better than Luminous because Exide inverter has some additional features. (salesman is also my friend). now I am confused. So still i did not buy. What is your opinion ?

53
Abhishek Jain (Mod)

Hi Rajesh,

Both Luminous and Exide are good brands. While comparing you should compare the features of the models and not just the brands. Some models of Exide may have better features than some Luminous model and vice versa. So it is important that you look at specific models.

54

Sir
I wish to buy a new Solar hybrid inverter 850 VA. LUMINOUS, Su-Kam, Microtek, & EXIDE. In these brands Which one you recommend for me. Also you can recommend any other brands better than this. I need one more information from you Which are the best solar panel brands (400Watts)
Thank you

55
Abhishek Jain (Mod)

Hi Ann.A,

Tata BP Solar, Jain Irrigations, Moser Baer, Sukam, Luminous are some top companies selling Solar PV Systems. Sukam, Luminous, Microtek also have good inverter systems.

57

Dear sir
I am using an inverter 850va local made. my area there is no power cut but some times only power failure. I wish to use solar power day time for my house ( 250 to 300 watt maximum ). i have separate wiring for iinverter it automatically switches to inverter when power failure.
Now my question is:1. after battery fully charged use solar power instead of grid power for lighting my house automatically only inverter line max 300w. (fridge t v mixi computer and the lightings and fan have separate grid line ) .so which charge controller prefer you for this purpose (automatic switching) or if i buy a new inverter which one you suggest. 2. I I buy luminous , su-kam or microtek hybrid solar inverter ( ups ) when sun available only charge the battery or while charging the battery excess power can i use for lighting and baterry fully charged can i use complete charge for lighting. if ilighting is possible inverter switches from grid to solar automatically or not
Thank you

62
Abhishek Jain (Mod)

Hello Mr Rashid,

Charging can be either through the grid or solar panel. It will not be possible to have both charge the batteries. So if you put solar panel, then you can have a switch to charge it either through panel or grid. But you cannot have both. Also your inverter needs to be solar inverter in that case.

I have 300 watt modules,20 amps pwm charge controller,150 ah a2 volt battery & non solar invertor & AC load. Please send me the circuit diagram for connecting & charging the battery(12 Volt system).

65

One thing that I want to know is, watts,, units of electricity, Ah of batteries, Hp in moters for pumps.how all these units be compared

66
Abhishek Jain (Mod)

You may read this article: https://www.bijlibachao.com/electricity-bill/what-are-watt-kilowatt-and-a-unit-of-electricity.html

Watt = rate of consumption of electricity (just like how speed is for distance).
Unit of electricity = Kilo Watt Hour or 1000 Wh = If 100 watt bulb is run for 10 hours. (just like actual distance travelled).
Ah of battery is energy stored = 12 V battery if it has 200 Ah storage would store 200 x 12 = 2400 VAh of electricity. There is a concept of power factor (you can read about it on: https://wp.me/p4hAhQ-1Y ) which related VAh and kWh. Assuming power factor of 0.8 2400 VAH = 2400*0.8 = 1920 Wh or 1.92 units of electricity.

HP in pumps is just like watts. 1 HP = 750 watts (it is just like how meter and feet are two different units of distance, watts and HP are two different units of rate of energy consumption).

67

How much is the cost difference between solar power system includes batteries & the the system without batteries. Second is can power companies purchase electricity from us.

68
Abhishek Jain (Mod)

It will depend on the number of batteries that you need. More the backup required, more will be the batteries required and more will be the cost. A 150 Ah battery that can store 1.5 unit of electricity costs about Rs 10000.

Power companies can purchase electricity from you however it depends on the state that you live in. The state should have a netmetering policy. Currently there are very few states (Karnataka, AP, Delhi, Punjab) that have netmetering policy.

69

What is the specification for 1kW off grid and 1KW on grid ? ( want to know solar panel in W, battery need to be used, charge controller and inverter VA)

thank you

70
Abhishek Jain (Mod)

Wattage of solar panels would be 1 kW in both the cases. Off Grid will have batteries and on grid will not have batteries. 1 KW off grid will produce 4-5 units per day so it would need about 3-4 150 Ah batteries. Inverter VA would depend on your appliances you want to run on it.

71

WHAT WOULD BE MY POWER CONSUMPTION FOR CHARGING 12V/100 AH BATTERY IN ONE CYCLE IN AN REGULAR INVERTER

72
Abhishek Jain (Mod)

Hi Mr Reddy,
For one cycle of charging a 12V/100AH Battery would consume about 1 units of power.

73

THANK YOU SIR,

BUT HOW YOU ARRIVED IT, FORMULA WITH WORK SHEET MAY KINDLY BE PROVIDED TO ANSWER TO THE CUSTOMERS WHICH WILL HELP ARRIVE AT OTHER BATTERIES OF 120AH,150AH ,200AH AND SO ON.

REGARDS

74

THE WATTAGE OF 100 AH BATTERY OF 12V IS 12X100=1200WH.BUT WE WILL BE CHARGING 70 TO 80% OF THE BATTERY IN LIGHT OF THE CUT OFF LIMITS.THEREFORE WE WILL BE USING BATTERY POWER OF 1200X0.8=960WH WHICH IS APPROXIMATELY 1UNIT OF POWER.MY QUESTION IS WHAT WILL BE THE AC POWER CONSUMED TO CHARGE THAT BATTERY WHICH GIVES ME 1 UNIT POWER.

75
Abhishek Jain (Mod)

You calculation of energy stored in the battery is right. So 1 unit is the amount of energy that is stored in a 100 Ah battery. However charging efficiency will vary from battery to battery and how efficiently it is designed. It can vary from 80-95%. So there can be 5-10% losses. On top of it if you leave a fully charged battery on charger, there will be trickle charging (http://en.wikipedia.org/wiki/Trickle_charging) that will cause more losses. So it truly depends on how you use it.

hi , i have a load of 600va ac and i want to run it directly on solar panels without the use of batteries, is it possible, if yes then how many watts of solar panels required and what other hardware need to be installed

79

HI Abhishek,

I am looking to purchase 40/42 inch full HD LED tv. My priority is for good picture quality and sound nothing other than this within a budget of 40-45 k.

I know SONY is the best in market. Suggest me something else other than SONY brand.

Most of the customers in this blog are looking for good picture quality and sound. But, you have suggested different brands for the same requirement. Say LG in some cases and Panasonic in other cases. Totally confused now.

Kindly suggest one best model in LG, PANASONIC and SAMSUNG brands, so that I can finalize one by seeing the models physically at showroom.

Regards,

Sam

80
Abhishek Jain (Mod)

Hi Sam,

Picture quality or sound does not just depend on brand but also on technical specifications of the model. A higher end model of LG would be better than lower end model of Sony. So one has to optimize brand, specs and budget. And that is why you would see Sony, LG, Samsung, Panasonic, Philips, etc on this discussion. However Sony is considered quite highly as a brand in TVs.

Now for your requirements and your budget these are the best I could get:
LG 42LB5510
Philips 40PFL4958/V7
Philips 40PFL4758/V7

However if you stretch a bit (up to 48K) you can also look at these models:

Samsung UA40F5000AR
Samsung UA40F5100AR
Samsung UA40EH5000R
LG 42LB550A
LG 42LB5610
LG 42LN5120
Panasonic TH-42A410D
Panasonic TH-42A400D

The tech specs of these models for picture quality and sound look very similar. However the extra features may vary.

Here are some more models that you can look at as you have increased the budget:

LG 42LN5400
Panasonic TH-42A410D

The tech specs are almost the same for models in this budget range. The features vary. I liked the LG 42LN5400 model because it does up-scaling to HD.

Samsung does not have 42 inch models. It has 40 inch.

Thank you very much abhishek for the quick reply. I am also looking forward for the below mentioned question answer asap.

1) LG42LB5610

2) LG42LN5710

3) LG 42LN5400

4) LG 42LB5510

Among these which is better in user friendly as well as quality in picture and sound. Budget is not a matter or if any other 42 inch model is better than this kindly assist me?

Thank you very much in advance

Hello Palani,

The specs of all the above models for picture quality look same. The first model has lower volume so I rule it out. LG 42LB5510 is a Smart TV and has quite a lot of features. So if you want smart TV then this one is better. If you are looking for Smart TV then you can also look at Sony KDL-42W700B.

Also, I am disturbing you a lot. Please let me know the best 42 inch LED full hd tv's in LG and philips by considering picture and sound. Kindly answer asap.

Thank you very much in advance.

Hi abhishek,

Planning to open up a poultry farm in a rural area ( mewat, haryana). Facing big trouble with grid electricity there. Electricity comes for 12 hrs during day time for 15 days and 12 hrs during night time for 15 days. Besides the voltage is so low that one has to apply for a personal transformer to get legible voltage. Getting this transformer installed in the farm has many red tape hurdles.

Pretty fed up with the local electricity dept. And have not been able to get the transformer installed, which in turn is delaying my poultry project.

Getting back to the point, i thought if I could run the farm completely on solar power

A shed (of 5000sq ft area)requires about 15 tubelights running at NIGHT ONLY for about 12 hrs say 7pm to 7am.

About 8 fans during summers for about 6 hrs during DAY time.

If we were to install solar panels on the shed roof......

1) how many solar panels of how many watts would be required for 1 shed

2) cost of this equipment for 1 shed

3)cost + capacity of solar inverter and battery reqd for 1 shed.

4) is it possible to get a subsidy from NABARD

5)Whom to contact for consultation and installation of equipment.

Regards,

Dr.Shiv Verma

Hello Dr Verma,

Here is what I suggest:

A regular tubelight would need 40-45 watts of electricity. If you replace it with a T5 tubelight (that costs about Rs 500 a piece with frame and Rs 100 for every replacement which will happen every 3-4 years), it will consume only 28 watts. Or even better if you put 20 Watts LED tube (costing about Rs 1800 and replacement happening every 10-15 years). Then you would significantly reduce your need of electricity.

Also if you put SuperFan (http://www.superfan.in) it will be just 35 watts fan instead of regular 75-90 Watts fan then again your electricity consumption would reduce.

If for e.g you go for 28 watts tubelight and super fan, then for 15 tubelights for 12 hours would need about (28x12x15)/1000 = ~5 units of electricity. And 8 fans would need (8x6x35)/1000 = 1.68 units of electricity. All in all if you get 7 units of electricity then it will be good enough for a day.

A 1 kW system that should cost you about 1.25 lakh would generate about 5 units of electricity. A 1.5 kW system would be more than enough for you. And would cost anywhere between 1.5 to 1.75 lakhs. And would need about 100-160 sqft of space (not more than that).

Subsidy is there but government keeps changing rules time and again and so it is better to contact a supplier to find out (as I keep hearing different things from different vendors). Many vendors keep following Bijli Bachao blog and reply to people's requests. You can post your requirement on this page and I am sure some vendors will reply back: https://www.bijlibachao.com/solar/solar-panel-cell-cost-price-list-in-india.html.

Thanks abhishek, wonderful info......will get back to u for ur expert opinion as and when I have something to ask.

96

can we connect directly solar panel to normal invert er using charge controller in between and then battery and normal light at house is their any risk or how can we find that panel is how much generating the electricity.

97
Abhishek Jain (Mod)

What is the size of panel that you have? If you use your normal inverter then your normal inverter will draw power from your electricity connection to charge the batteries, whereas you would want to charge the batteries from the solar panel.

98

Hi,

I had AC Inveter 900va, How much solar panel (WATS) required for me.and how much charger controller is required. I would like to convert inverter as a solar inverter... is it possible.

Thank you,,
