The payback has a hidden assumption
Every solar model assumes the system produces close to its potential for 25 years. In practice, output slips — soiling, a weak string, a derating inverter — and studies put avoidable underperformance in the high-single to low-double-digit percent of output. That comes straight off the saving in your model. The investment can still be sound; the return just needs to be watched, not assumed.
Evidence beats assurance
For finance, “the solar is working” is not a number. What you need is an independent, monthly record: expected versus actual output, weather-normalised, with any shortfall attributed to a cause and valued at your tariff. That turns the payback from a hopeful projection into a tracked, defensible figure you can put in front of a board or a lender.
Independence protects you at exit
When a system is sold, refinanced, or brought into due diligence, the buyer or lender does not trust the seller’s own dashboard — they trust an independent assessment. Having independent, string-level performance records from the start protects the asset’s value and shortens diligence, because the evidence already exists and holds up.
