What the estimate covers
PV Yield combines installed capacity, turnkey system cost, self-consumption, export value, maintenance cost, degradation, losses, and discount rate into one early-stage project screen. The output helps compare quotes before deeper engineering, tax, or utility review.

FAQ
Can PV Yield replace a bank-grade solar financial model?
No. It is an early screening calculator. Use local engineering design, tariff confirmation, tax advice, and lender requirements before investment decisions.
Which inputs matter most in France?
System cost, self-consumption ratio, retail electricity value, export tariff, available irradiation, shading loss, and financing terms usually drive most of the payback change.
Why are default tariffs marked as estimates?
Solar export value often varies by utility, state, province, customer class, policy year, and contract. Replace defaults with the tariff that applies to the actual site.
