How it works
Panel count = daily energy divided by peak sun hours, panel kW and one minus system loss, rounded up.

Common questions
Does this replace a site-specific solar design?
No. Shading, roof direction, climate data, inverter sizing and local rules require site assessment.
How does Solar panel count from energy usage calculate the result?
Panel count = daily energy divided by peak sun hours, panel kW and one minus system loss, rounded up.
What should I check before using Solar panel count from energy usage?
Uses only the values entered and does not fetch live prices, fees, rates or eligibility rules. Verify quotes, contracts, measurements and local requirements before acting.
