Your city

We use your city's actual solar data and electricity tariff to calculate your savings. Your estimate will be different from someone in another city -- and more accurate for it.

Your home type (optional)

This helps us estimate available roof space. If unsure, leave it -- your installer confirms during the site survey.

Monthly EMI

Longer tenure = lower monthly payment. Shorter tenure = less total interest. We show you both so you can choose.

SBI Surya Ghar offers 7% for systems up to 3 kW. Suryam's financing starts at 10%. On a Rs 1,02,000 loan, that is about Rs 200-400 difference per month. What you get with Suryam: approval in 5 minutes (not 4-6 weeks), no bank branch visit, a certified installer assigned to you, and all paperwork handled. That is the choice.

How did we calculate this?

We used the following data to estimate your savings:

City tariff: MSEDCL, Rs 9.38/unit effective rate at your consumption level
Solar generation: Mumbai averages 3.9 kWh per kW per day (MNRE irradiance data)
Seasonal note: Generation runs 15-30% higher in March-May, and 20-40% lower during monsoon. The annual average is what we use.
Panel degradation: 0.5% per year after Year 1.
Electricity tariff escalation: Rates have risen 3-5% annually over the last decade. Your savings grow each year while your EMI stays fixed.

"Maine apna Rs 5,200 ka bill enter kiya aur Rs 4,100/month savings dikhi. Mujhe laga thoda exaggerated hoga. Installation ke 6 mahine baad, meri actual savings Rs 4,400/month hain. Calculator ne conservative estimate di thi."

Nidhi Menon, 34, Bengaluru
5 kW system, installed June 2025

"The calculator showed my payback at 2.8 years. My CA friend said 'no investment gives 35% annual returns.' That was the moment I stopped researching and started ordering."

Vivek Tiwari, 42, Jaipur

"My wife and I had argued about solar for months. I showed her the Suryam calculator during dinner. When she saw the EMI next to our electricity bill, she said: 'Why didn't we do this two years ago?'"

Sameer Khan, 45, Mumbai
3 kW system

Common questions

Is this estimate accurate?

Does pre-approval affect my CIBIL score?

Why is Suryam's rate higher than SBI's 7%?

SBI Surya Ghar at 7% is genuinely the lowest rate available for systems up to 3 kW. On a Rs 1,02,000 loan, the difference between 7% and 10% is about Rs 200-350/month. What Suryam adds: approval in 5 minutes instead of 4-6 weeks, a certified installer assigned to you, and all PM Surya Ghar paperwork managed from start to finish. Whether that is worth it is your call -- and we respect that some families will choose SBI.
