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?
