Solar Power/Invertor?

Question

Hi,

Has anyone in India installed solar power for running electrical appliances in their home? And I dont just mean water heaters.

I have heard the TATA BP Solar panels cost around 20k per panel - anyone used them?

Also, if yu have a conventional invertor installed, solar power can also be used to power the invertor's battery.

Anyone please?

Answer 2

the panel cost depends on the wattage of the panels...

you can size the panel according to your requirement

i hope in india a 100W panel may cost you around 18000-20000

if we get 6 hours of proper sunlight falling on the panles.. u wil be approximately generating 600watts a day..

u can light a 100watt bulb for 6 hours

u need a solar charge controller before the battery so that there is proper charging of battery and no reverse current during night to damage ur panles....

u have to choos eyour panel according to your battery.. like whether it is a 6V , 12 V or 24 V battery

ex; a 12V panel will generate around 16.5V whicch after lossed in controller and wires will come to 14-15V.. which is required for  a12V battery for proper charging

solar water heater is only efficient and affordable option for common people in india..

there are many small companies in india doing solar works.. juz try search engines ..

Answer 3

Few months back there was this seller on ebay who claimed he had done such stuff the max he had installed was 25KW solar PV power. He used to sell inverters too. Search solar and see if you come up with any listings on ebay india.

Solar PV are expensive dont know where you got those 20k price from but the price depends on wattage of the panel. That cost may be for 80-100w panel so if you need about 2kw you need at least 20 such panels plus inverter + battery backup+installation.

These will help only if you have an biz premise which can use up all solar power produced in daytime and your commercial buy rate is very high (12-16 INR / unit)
