We take orders online and over the phone

Every kit can be bought online in minutes. Or call our team — we'll help you find the right size, talk through pricing, and take your order over the phone. Same fixed prices, either way.

Which path is right for you?

Our fixed-price kit configurations mean no hidden costs. But not every roof is the same — here's how to know which route suits you.

  • Buy online

    Right for you if: your roof is standard-pitch, unshaded, south- or south-west-facing, and you know roughly how much electricity you use.

    • Fixed price — no negotiation, no surprises
    • Choose your kit size now; MCS install included
    • Typical lead time: 2–3 weeks to installation
    • No need to wait for a site visit
  • Book a survey first

    Right for you if: your roof has chimneys, dormers, or shading; you're unsure about battery sizing; or you simply want an expert to confirm the recommendation.

    • Free, no-obligation professional assessment
    • Surveyor confirms kit size & roof suitability
    • Battery sizing advice included
    • Still get fixed pricing after your survey
  • Thinking about adding a battery?

    Battery add-ons (5kWh or 10kWh) are available with any kit. Our assistant can help you decide if storage makes financial sense for your usage pattern. See pricing below, or ask Owen.

  • Are you a real company or a reseller?

    Solar Online employs its own UK-wide regional installation teams — we don't subcontract to unknown third parties. Founded 2018, MCS-certified throughout.

From first question to working panels — four clear steps.

No obligation until you choose to buy or confirm your survey. Here's exactly what happens.

  1. Tell us about your roof & usage

    Ask our assistant, or answer a short checklist: roof pitch, orientation, shading, and your average monthly electricity bill.

  2. Get a specific kit recommendation

    Our assistant recommends a 3kW, 4kW, or 6kW kit — with or without battery storage — and explains why. Fixed price, no guesswork.

  3. Buy online or book a survey

    You decide: if you're confident, add to cart and book your install slot. If you'd rather have a professional confirm first, book a free survey — same fixed price after.

    The fork point
  4. MCS-certified install & warranty

    Our regional team installs to MCS standard. Includes commissioning, 25-year panel warranty, inverter warranty, and SEG registration so you get paid for export.

Choose your kit. No "get a quote" vagueness.

Every kit includes MCS-certified installation, inverter, mounting hardware, 25-year panel warranty, and SEG registration. Book a free survey first if you'd rather have a professional confirm the recommendation.
