Solar Power/Invertor?
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?

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 ..

Daniel asks…
How much does it cost for a Solar panel in a 2 Bedroom home per month in India?
I wanted to know the costs of Solar panel in India for a 2 bedroom house..is it on monthly basis , or one-time investment, maintenance costs…and if it costs more than our regular power supply provided by the government.

Henry Dover answers:
It really depends on how big the roof is ? And How many panels you want to install? The price is normally counted by the amount of electricity it produces (per kw). My guess is for a 2 bedroom house it will cost around 8 to 9 lakh rupees which you will have to pay yourself for the installation and it pays you back by saving your energy bill.
