Explore TOPCon →Bifacial modules can use rear-side irradiance when mounting, ground reflectance and site conditions support it.
Explore bifacial →Use monthly units, tariff and roof area to create an initial system estimate before a detailed survey.
Size a system →Check the exact module datasheet, current certifications, warranty terms and installation requirements before purchase.
Request documents →A practical planning assumption is roughly 5–6 square metres (about 54–65 sq.ft) of shadow-free roof per kW using modern modules. Final layout depends on module dimensions, spacing and obstructions.
A broad Indian planning range is around 1,400–1,600 kWh per year per kW, but actual generation varies with location, orientation, shade, weather and system losses.
On-grid systems prioritise grid-connected bill offset. Hybrid systems add batteries for selected backup loads. The right architecture depends on outage frequency, critical loads and budget.
Verify the exact model, power rating, efficiency, dimensions, electrical ratings, warranty, certifications, mounting requirements and current availability.
