Pros & cons

Pros

  • Panels can work independently: Two independent MPPTs allow the microinverter to manage each panel separately, so shading or a different orientation on one panel does not affect the performance of the other.
  • 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

  • PatioSun Max+ is better value: If you’re set on a PatioSun kit, the PatioSun Max+ adds 40W of panel capacity and uses higher-efficiency panels for only £30 more, giving it greater solar generation potential.
  • 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.
