Phuket Villa Solar Panels and Battery Due Diligence

Key Takeaways

  • Identify panel, inverter, battery and monitoring models, serial numbers, installer and commissioning date.
  • Confirm ownership and whether finance, lease or service obligations remain.
  • Review approvals, utility correspondence, single-line diagrams, warranties and maintenance history.
  • Compare monitored generation with bills while allowing for occupancy and weather.
  • Inspect roof penetrations, corrosion, drainage, earthing, protection and battery location with qualified specialists.

Verify ownership, approvals, warranties, generation history, roof condition, electrical safety and replacement exposure.

Buy the System, Not the Sales Claim

Solar can reduce grid use, but an installed array may also bring roof, electrical, warranty and replacement risks. Verify what transfers with the villa and how the system actually performs.

Technical and document check

  • Identify panel, inverter, battery and monitoring models, serial numbers, installer and commissioning date.
  • Confirm ownership and whether finance, lease or service obligations remain.
  • Review approvals, utility correspondence, single-line diagrams, warranties and maintenance history.
  • Compare monitored generation with bills while allowing for occupancy and weather.
  • Inspect roof penetrations, corrosion, drainage, earthing, protection and battery location with qualified specialists.
  • Budget for components nearing the end of warranty and define transfer access to apps and accounts.
