Solar equipment database
Structured records for the panels, inverters and batteries you’ll actually see in US quotes. Specs are for comparison; equipment price is not installed price — modules are ~$0.30–0.50/W of a ~$2.50–3.50/W installed system.
Solar panels
Wattage, efficiency, warranty terms, tiers. Discontinued models flagged.
Inverters
Microinverters vs string vs optimizers vs hybrid — and battery compatibility.
Batteries
Usable kWh, power, efficiency, warranty — kept separate from panel comparisons.
How we classify equipment
We use three transparent tiers — Value (×0.93), Mainstream (×1.00) and Premium (×1.14) — based on warranty terms, efficiency, track record and serviceability. Higher tier ≠ better financial return: a premium panel rarely changes payback more than the price difference itself. Records are dated and market estimates; verify specs at the manufacturer before relying on them.
