Question 1

How much roof area do I need for a home solar system?

Accepted Answer

Roughly 80 sq ft of shadow-free area per kW. A typical 3 kW home system needs about 240–260 sq ft, which fits comfortably on most independent house terraces.

Question 2

How much will I actually save every month?

Accepted Answer

Most Urja Saathi homes cut 70–90% of their monthly bill. A 3 kW system in North India generates about 360 units a month, which offsets roughly ₹2,800–₹3,200 at typical residential tariffs.

Question 3

What is the PM Surya Ghar subsidy and do I qualify?

Accepted Answer

It is a central government benefit of ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, capped at ₹78,000. Any homeowner with a residential connection and an Aadhaar-linked bank account qualifies. We file the entire application for you.

Question 4

How long does installation take?

Accepted Answer

The physical installation takes one to three days. Including the subsidy application, discom approval and net-meter installation, the full journey usually completes in three to six weeks.

Question 5

What happens on cloudy days and at night?

Accepted Answer

Your home draws seamlessly from the grid. With net metering, surplus units you exported on sunny days are credited against what you import, so your annual bill stays close to zero.

Question 6

Do solar panels damage the roof or leak during monsoon?

Accepted Answer

No. We use a ballasted or chemically-anchored mounting structure engineered for 150+ kmph wind loads, with waterproofing at every penetration point and a written structural warranty.

Question 7

What maintenance does a rooftop system need?

Accepted Answer

A wash every four to six weeks and an annual electrical health check. Urja Saathi's care plan includes scheduled cleaning, remote generation monitoring and priority breakdown response.

Question 8

What warranties come with the system?

Accepted Answer

25-year linear performance warranty on modules, 12 years product warranty, 5–10 years on the inverter depending on brand, and 5 years on our workmanship and structure.

Question 9

Can I get financing or pay in EMIs?

Accepted Answer

Yes. We work with partner banks and NBFCs offering rooftop solar loans from 7.5% p.a. with tenures up to 10 years, often with zero down payment for eligible applicants.

Question 10

Does my system work during a power cut?

Accepted Answer

A standard on-grid system shuts off during an outage for lineman safety. If backup matters to you, we design a hybrid system with a battery sized for your essential circuits.
