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.
  • High-efficiency panels: The supplied Trina Solar panels deliver an excellent 23% module efficiency.
  • Generous cable lengths: The supplied 5m AC cable and 4m DC cables give you useful flexibility when positioning the panels and microinverter.

Cons

  • High price based on current market: At £749.99, similar-capacity two-panel kits with dual-MPPT microinverters are currently available for less.
  • Flat-roof mounting costs extra: The standard brackets are suitable for ground or wall mounting, but the flat-roof mounting option adds £69.98 to the price.

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.
