Why this matters

Solar PV is a long-term investment. Over time, faults or degradation can reduce generation — often without obvious signs. Servicing helps confirm your system is safe and producing as expected, and fault finding can restore output if issues occur.

Our process

  1. Info: We review symptoms (error codes, output changes, timelines).
  2. Checks: Targeted inspection and tests to identify the issue.
  3. Fix: Repair/replace faulty components where appropriate.
  4. Confirm: Performance verification and guidance.
