Solar Rooftop Systems by Talwin
Do you want to reduce your power bill? A solar rooftop system is the smartest way to use your roof to make electricity. With strong sunshine for most of the year, Bangalore is ideal for rooftop solar — a well-designed system here generates roughly 4 to 4.5 units per kW every day.
At Talwin, we are trusted Solar Roof Top Distributors, Dealers & Suppliers in Bangalore, offering reliable Kamal solar rooftop systems for residential and commercial use. Whether you are a homeowner, an apartment association or a factory, we help you choose the right system, install it and get approvals from BESCOM. We work with certified high-efficiency photovoltaic panels — 545 Wp Mono PERC and 590 Wp TOPCon — for long-lasting performance.
What Is a Solar Rooftop System and How Does It Work?
A solar rooftop system uses PV (photovoltaic) panels on your roof to convert sunlight into electricity for your home or business.
- The solar panels on your roof capture sunlight and convert it into DC power.
- An inverter changes the DC into usable AC power.
- You use this power for lights, fans, fridges, ACs, pumps and machines.
- In on-grid systems, any extra power is exported to the BESCOM grid through a bi-directional (net) meter and credited to your bill.
We supply grid-tied, hybrid and off-grid inverters to match your needs, and install on both flat RCC roofs and sloped / sheet roofs.

Frequently Asked Questions – Solar Rooftop Systems
How much does a solar rooftop system cost in Bangalore?
For homes, an on-grid system typically costs about ₹55,000–₹70,000 per kW before subsidy, depending on panel type, structure height and inverter brand. A 3 kW home system often costs ₹1.7–2 lakh, and after the ₹78,000 central subsidy the net cost comes down significantly. Call us for an exact quote after a free site survey.
How much subsidy can I get for rooftop solar in Karnataka?
Under PM Surya Ghar Muft Bijli Yojana, residential consumers get ₹30,000 per kW for the first 2 kW and ₹18,000 for the 3rd kW — a maximum of ₹78,000 for 3 kW and above. Group housing societies / RWAs can get ₹18,000 per kW for common facilities. Subsidy rules are set by MNRE and may change; we confirm the latest at the time of booking.
Can I use solar during power cuts?
On-grid systems shut down during a grid outage for safety. If you want power during cuts, choose a hybrid or off-grid system with batteries.
How much roof area do I need?
Roughly 80–100 sq ft of shadow-free roof per kW. A 3 kW system needs about 250–300 sq ft.
Is solar suitable for apartments?
Yes. Apartments can install solar for common loads such as lifts, pumps, lighting and STP — and benefit from the RWA subsidy. We also install for individual penthouses and duplexes.
How long does BESCOM net-metering approval take?
Typically 2–6 weeks depending on documentation and BESCOM sub-division workload. Talwin handles the application, feasibility and meter replacement process for you.
Can I track how much power I generate?
Yes. All our inverters come with Wi-Fi / app monitoring so you can see daily, monthly and lifetime generation on your phone.
What is the warranty for solar rooftop systems?
Solar panels carry a 25–30 year performance warranty and inverters 5–10 years, depending on the model. Structure and workmanship warranties are also provided.
