Rooftop Solar Solutions for
Rooftop solar curated for individuals, housing societies, industries and communities. Design and engineering, net metering, installation and commissioning, and long term maintenance, delivered by GreenSutra across India as one accountable engagement.
Power generated where it is consumed
For individuals, societies, industries and communities.
India sees more than 300 sunshine days a year, a resource of about 5000 trillion units of solar energy annually, and is aiming for 500 GW from non fossil sources by 2030. Rooftop solar turns idle roof area into a working part of that transition.
Generating on the roof breaks the dependence on power produced at distant grids. Many rooftop systems now reach grid parity, supplying energy at costs equal to or lower than conventional power, and government subsidies, tax incentives and net metering programmes improve the economics further.
With a lifespan of 25 or more years and minimal maintenance needs, a well engineered rooftop system is a long term asset. GreenSutra handles design, net metering, installation and maintenance as a single engagement.
An Indian origin sustainability practice operating since 2016, GreenSutra brings the same engineering discipline to rooftops worldwide.
How a rooftop solar project runs
One accountable engagement from feasibility to long term output.
Site audit and feasibility
Roof condition, shading and structure reviewed with the energy profile of the site to confirm what the roof can deliver.
System design and proposal
Custom engineering sized to the load, the roof and the budget, with precision design for seamless integration and efficiency.
Net metering approval
Net metering application and utility coordination handled end to end so the site can export surplus power for credits.
Installation and commissioning
Skilled installation and commissioning, with the system operational and optimised from the first day of service.
Operations and maintenance
Monitoring, regular inspections and quick fault resolution protect performance across the 25 year life of the system.
How net metering works
Solar serves the site first; surplus exports to the grid for credits.
Panels convert sunlight into direct current across the array strings.
The grid tie inverter converts direct current into alternating current for use on site.
Connected loads draw solar power first, before any unit arrives from the grid.
Surplus generation flows through the bidirectional meter into the grid and earns credits.
When demand exceeds generation, the site draws from the grid and the meter records the difference.
Generation powers the site load first. The bidirectional meter records exported surplus and imported units, and the utility settles the difference. Net metering keeps the site connected to the grid while excess energy earns returns.
Net metering turns surplus generation into grid credits. A site review shows what the roof can earn.

The key advantages of adopting solar power for homes and businesses.
Reduced electricity bills
An affordable way to cut electricity costs. As systems reach grid parity, rooftop solar supplies energy at costs equal to or lower than conventional power, delivering long term savings.
Low maintenance
Panels require minimal maintenance and last 25 years, making rooftop solar a dependable long term investment.
Clean and sustainable power
A renewable source that helps meet climate goals and significantly reduces environmental pollution.
Subsidies and net metering
Government subsidies and tax incentives reduce initial costs, and net metering lets surplus energy flow back to the grid for added returns.
