Guide Why you should install a solar rooftop system

HI am , looking at this and excellent thread. I have got a quote for 285000 for 5 KW single phase, I want 6KW sadly in Karnataka it seems after exceeding 5KW we have to go for 3phase hence cost jumps to 345k for 6KW three phase system all included, about 45k per KW 45k 3ohase invertor, 30k for frame work, rest is all fees and bribe money. Selco is the vendor.
For context I run a EV and my monthly bill is 5-6k approx 500 to 600 units. 3k home-3k EV

As @superczar claims, "you get better ROI by keeping production slightly less than consumption instead of the reverse."
By that logic, get the 5KW plant.
Incidentally, a jump of INR 60,000 for a 6KW 3Phase plant isn't that prohibitive from a Single Phase 5KW plant.
The 3 Phase Array has its own benefits.
Additionally, your calculations do not match:
45K/KW. For 6KW = 270K
+ 45K 3Phase Inverter
+ 30K for framework
Adding the above comes to 345K.
Where is the "Rest" for Fees and Bribe money?

Not for the water heaters . 15 k is not much compared to the cost of a 15ltr one . Especially if you have 2-3 bathrooms
In Bescom the sanctioned load = max capacity solar you can install. Increasing sanctioned load itself costs a lot due to bribes .

I read this somewhere.
If your sole purpose of installing solar panel is to save money, it's smart to consider more than just your electricity bill savings. Think about the total cost of installation and compare it to what you'd earn if you kept that same money in a bank.
For example, if you spend ₹X on solar panels today, you expect to recover that cost over the years through lower electricity bills. But if you had instead put that ₹X into a fixed deposit or savings account, it would earn interest.
So, to really break even on your solar investment, the money you save on power should be at least equal to (or more than) what you would have earned in bank interest over the same period.
This helps you understand the true value of your investment, not just in terms of energy, but also in terms of smart money decisions.
Is this true?

I can be sure that the money invested in installing an On-Grind Solar Panel is WAY BETTER than Money kept in an FD.
Yes, the Earnings Per KW are Lower than what the Consumers Pay to the DISCOM Per Unit consumed.
However, Solar Panels have a Warranty/Assured Service Life of 25 Years. In other words, they should work for a LONG time.
Secondly, Money earned on an FD is TAXED. Money Earned on an On-Grid Plant is deducted/proportional with the Units Consumer Consume. You are essentially making your Electricity Consumption FREE, which is NOT taxed.
Thirdly, investment on an On-Grid Plant is recovered between 4-8 years. Thereafter it is FREE.
Essentially, an On-Grind Plant (at least until the time Govt. is Subsidizing the installation) is a better investment option.
