How plug-in solar panels work

A plug-in solar kit is a small solar system designed to feed power into your home through a standard socket, reducing the electricity you draw from the grid while the panels are generating.

The main parts

A typical kit includes one or two solar panels, a microinverter, mounting hardware and a cable with a UK-approved plug. The panels produce DC electricity; the microinverter converts it to AC electricity suitable for household use.

Why self-consumption matters

The value comes from using the solar electricity while it is being produced. Running daytime loads such as routers, fridges, laptops, washing machines or battery chargers can improve payback. If your home is empty all day and little power is being used, savings can be lower.

What to compare later

• Microinverter compliance and maximum AC output.
• Panel wattage, warranty and expected degradation.
• Mounting options for balcony rails, patios, fences or flat roofs.
• Retailer support, returns and replacement parts.
• Clear UK documentation, not just translated EU instructions.
