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.
  • Ground or wall mounting options: Octopus offers a choice of ground or solid-wall mounting, and the ground-mount system is particularly simple, with relatively few components to assemble.
  • Eligible for export payments: Octopus customers who buy this kit can join its Outgoing Prime export tariff and get paid for surplus electricity.

Cons

  • Fixed, low mounting angle: The supplied ground mount is simple to assemble, but it does not allow tilt adjustment and holds the panel at a relatively shallow angle. This limits your ability to optimise generation and gives the kit a larger ground footprint than many other ground-mounted options.
