Pros & cons

Pros

  • Preassembled and ready to position: The panels arrive already attached to the ground mount, so there is no frame assembly required before use, making setup quick and simple.
  • Easy seasonal angle adjustment: The mounting system has three pre-configured tilt positions, making it easy to change the panel angle to better suit the sun’s height at different times of year.

Cons

  • Very high price for a single-panel kit: At £650, this is one of the most expensive single-panel kits on the market.
  • 475W output isn’t achievable: The 450VA microinverter caps maximum output at around 450W, so the kit can never deliver the panel’s full 475W capacity.
  • Limited panel information: Modular Solar does not disclose several key panel specifications, making it harder to assess the quality, efficiency and long-term performance of the panel itself.
  • Timber frame may need more maintenance: The mounting frame is made from timber, so it may require more ongoing care than metal or moulded-plastic alternatives.

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.
