SolarSavingsRoof Area Estimator
Calculate your maximum solar capacity (kW) based on your available shade-free roof space.
Flat Roof (RCC)
Requires space between panel rows to prevent shadows. Needs ~100 sq ft per kW.
Slanted / Tin Roof
Panels are mounted flush. Highly space efficient. Needs ~70 sq ft per kW.
Maximum Solar Capacity
0 kW
This is the maximum grid-tied system size you can physically install.
Total Panels
0
Assuming standard 540W Mono-PERC modules.
Est. Generation
0 Units
Estimated electricity generated per month.
Note: The standard calculation assumes the use of modern high-efficiency 540W DCR modules. Flat roofs require more area (approx 100 sq.ft per kW) to account for the physical walkway and shadow-clearance distance between tilted array rows. Slanted roofs (approx 70 sq.ft per kW) assume flush mounting facing South.
