Key Takeaways
- Identify who owns every panel, inverter, battery, meter and monitoring account; check for finance, lease or installer claims.
- Obtain designs, invoices, serial numbers, commissioning tests, warranties and service history.
- Inspect roof penetrations, waterproofing, corrosion, cable protection, earthing, isolators and fire access.
- Compare interval data and bills with realistic occupancy; do not rely on a seller's headline saving.
- Verify current utility connection, metering and any export or purchase arrangement directly with the relevant provider.
Verify ownership, approvals, roof condition, output evidence, batteries, warranties and grid arrangements before valuing a solar-equipped property.
Phuket Property Solar System Due Diligence
Solar can reduce grid use, but panels alone do not prove savings or a transferable asset. A buyer should separate the equipment, roof, electrical and utility evidence before assigning value.
