Frequently asked questions
Does Capital Solar offer Insurance Backed Guarantees (IBG)?
An IBG is essential — it covers the workmanship warranty if the installer ceases trading. MCS-certified installers usually offer IBG via the MCS scheme. Confirm Capital Solar provides an IBG certificate at handover; don't accept a workmanship guarantee that's only as good as the installer's continued existence.
Is solar still worth it in Oxford given the climate?
Oxford gets enough annual sunlight for a typical 4 kW domestic system to produce roughly 3,200–3,800 kWh/year. Payback periods are typically 8–11 years at current electricity prices. Ask Capital Solar for site-specific yield modelling based on your roof orientation, pitch and shading.
Should I get multiple quotes alongside Capital Solar?
Yes — three quotes is the UK standard for solar PV. Use Capital Solar's quote as one of those three. Compare not just price but warranty terms, MCS certification, and panel/inverter brands. Specs vary widely between installers.
What warranty does Capital Solar typically offer?
UK solar workmanship warranties commonly run 5–10 years; panel performance warranties 25 years; inverter warranties 5–12 years. Ask Capital Solar specifically what's covered, who underwrites it, and what happens if they go out of business (an MCS Insurance Backed Guarantee — IBG — covers this scenario).
How does Capital Solar's quote process work?
Capital Solar typically begins with an initial enquiry via phone or website, followed by a desktop assessment and on-site survey. Ask whether the quote is fixed-price or estimate-only, and confirm what's included (scaffolding, DNO application, commissioning).
