A Beginner’s Guide to Choosing the Right Solar System
Switching to solar can feel confusing, units, subsidies, system sizes.
Why people are choosing solar
For years, electricity in India felt like an extra monthly tax. Rising bills. Unreliable power. Generators that burn both diesel and money. But now, homes and businesses are turning to the sun, and the change is real. Solar isn’t just for villas anymore. Even small shops and rural homes are installing solar systems to cut costs and stay powered.
*What fits your need on-grid or off-grid?*
There are two types of solar systems:
On-grid
- Links to your existing electricity line
- No battery needed
- Cheaper setup
- You can sell extra power back (net metering)
Off-grid
- Works independently with battery storage
- Good for long power cuts
- Costlier because batteries are expensive
How much solar do you really need?
Look at your electricity bill—how much you use in a month. Divide by 30 to find daily use. In India, 1 kW sunlight gives about 4–5 units daily. So, if your home uses 12 units a day, you need about a 3kW system.
This can bring down the cost of a 3kW system from Rs2 lakh to Rs1.2–Rs1.3 lakh.
One lakh households have already benefitted, saving on electricity and earning from surplus energy.
States like Gujarat are leading in installations, generating over 1,200 MW and saving huge amounts of coal and pollution.
Government schemes that make it easier
The Surya Ghar Yojana has a Rs75,000+ crore budget to help one crore homes get solar systems.

Delhi recently boosted its subsidy to Rs10,000 per kW (capped at Rs30,000) for systems up to 3 kW.

And if you live in Haryana, expect dual support—central + state subsidies—and help through local DISCOMs.

Why now is the best time to switch
Electricity bills keep rising, but solar gives a fixed cost for 20–25 years.
Subsidies are strong right now, and technology is cheaper than ever.
India’s rooftop solar market just crossed 100 GW, showing how the shift is real.
How to get started, step by step
- Check your last three electricity bills, how much power you use.
- Choose on-grid if you have grid access, battery only if you face blackouts.
- Check if your roof gets sun for 5–6 hours and is strong enough.
- Apply for subsidy on the national portal and pick an MNRE-approved vendor.
- Compare at least 2–3 quotes before investing.
- Clean panels every few weeks; check inverter and wiring yearly.
In a nutshell
Choosing solar isn’t about the fanciest system you can find.
It’s about the right system, one that fits your needs, roof, and pocket.
With subsidy and falling prices, solar is becoming an obvious, smart choice. It saves money, gives energy independence, and helps our planet.
The sun is free and reliable. Time to use it.
