Are Plug-In Solar kits easy to install?
Installing a Plug-In Solar kit requires NO experience, and is a simple plug and play assembly. You don’t need to be a qualified electrician, just a ‘skilled person’ [1].  You can install your Plug-In Solar kit in the GARDEN, on the PATIOSHEDPERGOLAWORKSHOPGARAGESTABLE, BEACH HUT, SUMMER HOUSE, OFFICE or HOUSE roof. Anywhere with a mains grid connection. It’s up to you.

The Plug-In Solar Advantage
With standard Solar PV kits, electricity generation is dependent on the panel that is performing the worst.  These types of systems will will not perform well with panels that are oriented in multiple directions or if panel shading is an issue.

Our Plug-In Solar Kits use Micro-Inverters to take full advantage of the production capability of each individual solar panel, regardless of shade or orientation to the sun. This ensures each panel can produce the maximum power and is not affected by the performance of another panel in the array.

The Plug-In Solar System is flexible, and modular so you can design a kit to fit your current budget and energy needs, and expand it later as you wish. The system is completely modular, meaning if you want to add more panels, or a solar battery, this can be simply achieved.

Plug-In Solar Kits are also Energy Storage Ready, meaning a battery system can easily be added to our kits using the Enphase AC Battery Storage Module.
