Pros & cons

Pros

  • Good value based on current market: At £444, it’s one of the cheapest two-panel kits available today, while still offering a strong overall specification.
  • High-efficiency panels: The supplied JinkoSolar panels deliver an excellent 23.5% module efficiency.
  • Flexible mounting options: The supplied mount suits ground, wall or balcony installation and adjusts from 15° to 45°, helping you optimise the panel angle to capture more sunlight and improve generation.

Cons

  • Same kit, black frame: Same specification as the City Plumbing JNK-940W-BW-1 kit, with a black mounting frame adding £12.
  • 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.
  • Higher-capacity kit costs only slightly more: The City Plumbing DMEGC 1030W kit adds 90W of panel capacity for just £24 extra, making it worth considering if you have room for the larger panels.
  • Often out of stock: Their strong pricing means City Plumbing kits can sell out quickly, so availability is often inconsistent.

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.
