Our calculator uses regional solar irradiance data and average tariff benchmarks to provide highly indicative, engineering-grade results.
Required System Size
Engineering Assessment
Recommended Capacity
Estimated Area
The system size is rigorously calculated based on your local electricity consumption and optimum generation potential. Rooftop area estimation assumes standard high-efficiency monocrystalline module architecture.
If rooftop space is structurally constrained, our engineering consultants can evaluate alternate configurations (like elevated modules).

Invest in Solar with ₹0 Down Payment
We offer structurally integrated financing solutions to enable immediate solar adoption without any upfront capital expenditure. Let your operational savings fund your solar transition.
Our OPEX (Zero CAPEX) model ensures you can install a commercial-grade tier-1 solar system with ₹0 upfront cost. Instead of an EMI or loan, you simply pay a highly reduced monthly bill exclusively for the solar electricity generated, structurally lowering your overall energy cost constraints.
