Pitfalls of typical conventional solar warranties

Each manufacturer’s warranty covers one component of the entire system, leaving you with at least 4 separate warranties (panel, inverter, racking, monitoring). With a conventional solar warranty:

  • You must pay to package and ship defective panels
  • You must present the original physical proof of purchase
  • You must pay to replace panels damaged from rust
  • Hardware functionality is treated as binary (either it's on or off)
