One connected solar library
Costs depend on technology. Projects depend on policy. Performance depends on design and upkeep. The library keeps those links clear.
Technology and equipment
How panels, inverters, batteries and other parts work across small and large solar systems.
02Costs and finance
Project prices, generation value, payback, loans and calculators for sound financial decisions.
03Projects and performance
Planning, installation, operations, maintenance and output from rooftops to solar farms.
04Policy and schemes
Government schemes, subsidies, metering, electricity rules and official notices.
05States and industry
State rules, solar manufacturing, market change, tenders and major projects across India.
06Solar calculator
Estimate residential system size, cost, subsidy, generation, savings and simple payback.
Use your bill and roof areaDifferent projects need different answers
A household, a factory and a solar park should not follow the same buying checklist.
Homes and housing
Residential rooftops, apartments, housing societies, PM Surya Ghar, net metering and home backup.

Planning a home system?
The calculator remains a focused tool for residential solar. Use it for a first estimate, then check costs, equipment, subsidy and local electricity rules.
Use your own details
Enter a recent bill, your state, clear roof area and backup preference. The tool shows every main assumption.
