Has anyone here installed Solar Rooftop System for electricity generation in Karnataka, especially Bengaluru?

What would be the total cost for a 1KW or 2KW system be? And what’s the average number of units you generate?

And will we get any subsidy here?

@ G-Gowda
I installed 3kw last year in Gujarat. They offered 40% subsidiary. It cost me around 96k with structure.

Panel was from Adani with 25 yrs. Warranty
Wire – Polycab
Inverter – Solis

Daily generation around 12-13 Units. It Depends on weather.

Bro Gujarat and Punjab have good subsidies. I wanted someone experienced in Karnataka. That is a phenomenal price.

I called Tata and local solar companies. They quoted 2.1-2.4 lakhs for 3KW system.

1.4-1.6 lakhs for 2KW system. And subsidy is my headache according to them. They will not come to that.

Tata guy said Karnataka govt hasn’t given tender yet and Tata and Adani hasn’t applied for it anyway.

Solar shouldn’t be installed with a mindset to earn.

ESCOMS will take away the incentives in a few years since they will incur loss due to solar rooftop homes.

As per my past requirement 1.5-2 KW would be enough for me. I have installed more considering future usages etc.

Govt. Will give 2.25rs. Per unit (While charging 6-7rs. Per Unit for consuming) for Extra electricity generated from us at the end of each financial year. So breakeven cost for usage will be done in around 4 yeras but for earning breakeven years will be more like 6-8 years.

Maintenance yet not needed except washing panel every 15 days. Panel has warranty of 25 yrs., inverter has 5 yrs. So any major Maintenance cost I have to bear will be after 5 years.

Solar panel prices have come down drastically in recent times.. Tata n others are still quoting a very high price just because for their brand name..

Look at luminous etc for a good priced setup. You can get their dealer contact online if you search. Talk to a few of them n collect a breakup of the equipment and installation seperately n compare.

Installation is not a big deal, but they to make it sound as if it is a specialist job. Anyone with basic masonry n structural work knowledge can do it IMO.

If going for govt subsidy schemes, be cautious of their registered suppliers.. substandard workmanship, cheap quality kits.. just keen on trying to eat up the subsidy in conjunction with the officials..

Then how do we choose?

Tata atleast can be trusted to be in the market and replace the panels if something happens in the next 25 years under warranty. Can we trust Luminous the same way? And can we trust subsidy vendors with warranty replacement?

Without subsidy the price is too much and doesn’t make much sense for me.
