Verify ownership, approvals, design, generation records, warranties, isolation, roof condition and replacement exposure.
Solar value depends on the whole installed system
Inventory panels, mounting, cabling, isolators, inverter, monitoring, battery and grid connection. Confirm who owns every component and obtain design drawings, approvals, commissioning results, generation history, alarms, service invoices, serial numbers and transferable warranties. Match monitoring access and electricity bills to the claimed performance.
Ask qualified electrical and roofing specialists to inspect earthing, surge protection, shutdown labels, roof penetrations, corrosion, ventilation and fire access. Budget for components with different useful lives. Read the villa electrical guide, roof-waterproofing guide and buyer service.
