DIY solar installation guide

Plan your own solar install from scratch. Work through the six steps below to size your system, pick every component, and leave with a complete shopping list and cost estimate.

UK legal note: DIY solar installation is legal in the UK. The consumer unit connection requires Part P sign-off and a Building Regulations notification, and SEG payments require an MCS certificate. We can handle all of this — see Step 6.
  1. Step 1

    Assess your energy usage

    Calculate how much electricity you use annually — this determines how many panels you need.

  2. Step 2

    Choose your solar panels

    Pick the panels that fit your roof space and budget. We'll calculate how many you need.

  3. Step 3

    Choose your inverter

    The inverter converts DC power from your panels to AC for your home. We size it to match your array.

  4. Step 4

    Add a battery (optional)

    A battery stores surplus generation for evening use. Skip this step if you prefer a time-of-use tariff.

  5. Step 5

    Mounting, wiring and accessories

    Racking, DC cable, MC4 connectors, isolators, and generation meter — the full bill of materials.

  6. Step 6

    Certificates and sign-off

    We handle Part P sign-off, DNO notification, and MCS certification — making your DIY install fully compliant and SEG-eligible.
