Estimate solar system size from your monthly electricity use or bill. This free calculator shows capacity in kW, 550 W panel count, roof area, and estimated generation.
Solar calculator · State-wise solar subsidy guideThe right system depends on your grid connection,
energy needs, and backup priorities.
Solar powers your property while the grid supplies any shortfall. Surplus can be exported where local metering rules permit. A standard on-grid system has no battery backup and shuts down during power cuts for safety.
A standalone system uses solar panels, a suitable inverter, and typically batteries to supply power without a grid connection. Battery and panel capacity must be designed around daily loads and periods with limited sunshine.
A suitably configured hybrid system combines solar, grid power, and batteries. Backup circuits and safe isolation can keep selected loads running during outages; capability depends on the inverter and battery design.
The solar calculator estimates panel capacity from monthly energy use. It does not size batteries, backup duration, or peak appliance loads. Ask our team for a site-specific design.
Enter your average monthly electricity consumption to estimate a system that could generate the same amount of energy. Don't know your units? Use your electricity bill instead.
Use a 12-month average for a better estimate.Planning estimate only: 30 days/month, 80% system performance after losses, 550 W panels, and roughly 100 sq ft of rooftop per kW including spacing. Designed to offset monthly energy, not guarantee zero bills or power during outages. Shading, seasons, roof layout, sanctioned load, and local grid rules require a site assessment. Battery sizing, installation costs, and subsidies are not included.
The PM Surya Ghar: Muft Bijli Yojana supports eligible households in adopting rooftop solar. We'll help you understand the scheme and navigate the next steps.
For eligible individual residential grid-connected systems.
Not for commercial systems, batteries, or off-grid installations.
| System size | General states / UTs | Special-category states / UTs |
|---|---|---|
| 1 kW | INR 30,000 | INR 33,000 |
| 2 kW | INR 60,000 | INR 66,000 |
| 3 kW and above | INR 78,000 | INR 85,800 |
General rate: INR 30,000 per kW for the first 2 kW, then INR 18,000 for the next 1 kW. Special-category rate: INR 33,000 and INR 19,800 respectively. No additional central assistance above 3 kW.
Special-category locations: the eight North Eastern states including Sikkim, Himachal Pradesh, Uttarakhand, Jammu and Kashmir, Ladakh, Andaman and Nicobar Islands, and Lakshadweep. This higher central rate is not a separate state subsidy.

Big decisions start with good questions.
Talk to our teamA suitable rooftop has enough usable space, good sunlight, and a sound structure. Our team can assess shading, roof condition, and your electricity needs before recommending a system.
Eligible residential consumers may receive support under the scheme. Eligibility, system requirements, and subsidy amounts follow current government rules. Check the official portal or contact us for guidance.
Standard grid-connected systems shut down during a power cut for safety. Backup requires a suitably configured hybrid or off-grid system with storage. Let us know if backup power is a priority.
Solar panels need periodic cleaning and system checks. The right schedule depends on dust, weather, and your installation. Your installer should provide safe maintenance guidance for your system.
