Solar: Maximizing Savings with Slab Rate Electricity pricing

[roa]

I've been considering installing a solar panel system on my property in an effort to reduce my electricity costs; which is roughly 3k per month right now with 341 units.

Below is the slab from MAHADISCOM

|----------------------------------------------|

| Units | Rate (Rs per unit) |

|------------------|---------------------------|

| 0 - 100 | 4.41 |

| 101 - 300 | 9.64 |

| 301 - 500 | 13.61 |

---------------------------------------------------

So as per this, the lower slab I am in the lower my bill will be.

I have been recommended to install a 3kW solar system which costs around 1,81,526.

The payback period for this system will be roughly 5.5 yrs ( 1.8lc /(12 month*3k bill)

I have been thinking of installing a system of only 1KW since I will be maximizing my price to savings.

+------+---------+---------+---------+

| Unit | Bill | 1kW | 3kW |

+------+---------+---------+---------+

| 341 | ₹ 2,927 | ₹ 1,318 | ₹ 0 |

+------+---------+---------+---------+

So payback for 1kW system will be 4.8 yrs.

My question is I am right in these assumptions and calculations, or am I missing something with net metering with solar?

Is this an effective way to reduce the payback period? Since I won't be living in my current house for more than 8 years from now

@roa 1.8 lac for 3kw too high . Someone is looting you . Do some research on YouTube
