Use your own per-kW price range or an installer quote. No unverified market price is silently assumed.
Understand the calculation
On-grid systems operate with the grid, hybrid systems add backup capability, and off-grid systems rely on storage and independent generation. Actual quotes vary, so the calculator prioritizes user-entered rates and quotes.
Results are planning estimates, not engineering designs, quotations, eligibility decisions, or guaranteed financial returns.
