How we rank

Kits are sorted by estimated payback: total price (including delivery and any parts not in the box) divided by the yearly saving for the spot you choose. Savings use EU PVGIS solar data for your postcode area and assume you only save on power used in your home as it's made, valued at your unit rate. We check prices by hand and link to the retailer; some links earn us a commission, which never changes the order. More on our method.
