I got to know that one of my friends is working in a power electronics company which designs inverters & stuff like that!

They have a solar power station in their product list! see the brochure!

According to my friend, the cost per watt of a hybrid system would be around Rs 100/- & that of a standalone system would be 1.5 times that!

Hey Hellmet! Nice intent there.

Hope this is not too little too late.

Cost:
As mentioned earlier, 1 kW system should cost you @ 1.2 lac.

MNRE (Ministry of New and Renewable energy) has capped cost of 1 kW of power pack without battery backup at Rs 1.9 lac. MNRE provides subsidy to the extent of 30% of this benchmark cost. Availing this subsidy may not be easy. If you have "connections", it can be done faster.

There is also a provision of claiming accelerated depreciation (@80%); but since you are a residential user, I am not sure how much it holds true for you.

Output:
A typical 1kW power pack will give you not more than 4-4.5 kWh a day (on sunny days). Thus extending you payback.

Payback:
At Rs 6 per kWh and with a capital subsidy of 30%, your payback turns out to be 8.5 years. And this is w/o battery backup. As mentioned, unless you consume this during the day, your payback extends further (if you run w/o batteries).

If you opt for system with battery, you'll need a storage space either on the roof or in your apartment. If you opt to store batteries on the roof, you will need a room like structure (which may not be possible) and also be wary of the fact that with increasing temperatures, battery life comes down. Expect to replace batteries every 5-6 years. All this will add to your costs.

Ideally, with current costs, a metro is not a place to install these type of systems; unless you really really want to "go green".

Alternative:
There are smaller systems available. Refer attached file. SPV.pdf

Check with NEDCAP http://www.nedcap.gov.in/, they will be able to give you details of some suppliers.

Reviving an old thread. Photovoltaic prices crashed over the last year and most of the PV manufactures in Germany and US went bankrupt. This is mainly due to large increase in PV production from China. Current PV prices are at 80 US cents for 1W.


Rough calculation for a 2kW PV system with storage-
PV 2kW -1600 USD
Hybrid inverter- 1200 USD
Storage-(150Ah x 48V)- 720USD
Total- 3520 USD (INR 193,600)
[FONT=&quot]So there is huge potential for solar home systems in the coming years.[/FONT]

What type of LED bulbs can be used with such systems ? What is the 'base' design of these bulbs ?

I am looking to replace the current CFL bulbs with LED bulbs. Can I directly swap the CFL bulbs with LED bulbs ?
The PV lighting system is by SELCO.
