- Request written confirmation of excluded work and recurring fees.
- Compare equipment, roof scope, warranties and generation evidence.
Assumptions & limits
- Manually normalised solar proposals; allowances are user scenarios, not supplier quotations. No PDF extraction.
- Inputs are unverified. EUR only; no automatic currency conversion or jurisdiction-specific entitlement is inferred.
- Allowances are scenarios, not supplier prices. Equipment quality, warranty and contract scope are not inferred.
- Both proposals use the entered common yield and blended energy value with constant cash flows; roof geometry, self-consumption differences, degradation and taxes are not modelled.
