Pros & cons

Pros

  • Bifacial panels: Both panels can generate electricity from light reaching their front and rear surfaces, which may provide some additional generation where reflected light reaches the back of the panels.
  • Strong warranty cover: The kit includes a 12-year microinverter warranty, a 25-year panel performance guarantee and a 2-year warranty on the mounting system and accessories.

Cons

  • Panels are not independently managed: With a single MPPT, the microinverter has to manage both panels together, so one panel receiving less sunlight can hold back the performance of the pair. This makes the kit better suited to setups where both panels can face the same direction.
  • Limited mounting flexibility: The supplied mounting system is for ground installation only and uses a fixed panel angle, giving you less flexibility than kits with adjustable or multi-location mounting options.

Other items you may need

This plug-in solar kit includes all of the main equipment needed to get set up, but depending on where and how you install it, there may be a couple of additional items worth considering.

Ballast

If you’re installing the kit freestanding, you’ll need ballast to weigh down the mounting frame and help prevent movement or uplift. Follow the manufacturer’s instructions for the required ballast weight and positioning.

Cable protection

If the AC cable runs through an exposed area, split conduit can provide additional protection. Because the plugs and connectors are moulded onto the cable, split conduit can be fitted around it without needing to remove them.
