Generate professional MCS-ready solar quotes in minutes — including DNO fees, zero-rated VAT, scaffolding and battery storage.
Homeowners typically contact 3–5 companies before choosing an installer. A professional PDF quote from SolarCalc helps you stand out and win the job.
📄 Example Quote PDF
Most UK solar installers are losing jobs to competitors with better-looking proposals — not better prices.
45 minutes per quote adds up fast. When you’re on the tools all day, there isn’t time to spend an evening building proposals.
One change to a system size means updating ten cells manually. Spreadsheets break, formulas get corrupted, and version control is a mess.
Plain printouts and Word docs don’t inspire confidence in a £10,000–£15,000 purchase. The customer buys the professionalism first.
Homeowners compare every installer they contact. A detailed branded PDF quote signals professionalism before you’ve even spoken to them.
Panels, inverters, payback times — homeowners research it all. A quote that shows your working builds trust before the second call.
SolarCalc is a PDF solar quote generator built for UK MCS installers. Fill in your customer’s details, hit generate, and send a professional quote the same day.
UK irradiance zones, Smart Export Guarantee rates, zero-rated VAT, and MCS compliance requirements are all pre-loaded. No configuration needed.
Change a panel count or system size and every figure updates instantly — yield, savings, payback period, and SEG income. No formulas to maintain.
A branded, polished PDF quote generated in one click. Your customer receives a document that looks like it cost thousands to produce.
Follow-up email copy written for you. Attach the PDF, copy the template, and send — no blank-page anxiety after a site visit.
Enter your customer’s postcode and get their roof’s actual solar irradiance data from the EU’s PVGIS database — production estimates calculated for their exact pitch and orientation, not a generic assumption.
Every page is laid out to build trust and make it easy for homeowners to say yes.

The layout looks professional. Customers actually read it rather than just looking at the price. That’s made a real difference to how many jobs I close.

Competitor pricing and positioning are based on publicly available information and may change. OpenSolar is a strong design and proposal tool — SolarCalc UK is built to sit alongside it for UK-specific MCS quoting, not replace it.
SolarCalc UK is a standalone tool — it doesn’t connect to OpenSolar, EasyPV, or any other platform. You enter your customer’s details directly and it generates a PDF quote on the spot. No imports or exports needed.
Nothing at all. SolarCalc UK runs entirely in your browser — on your phone, tablet, or laptop. Open the page and start immediately. No app to download, no account to create, no software to update.
Quote data stays on your device — nothing is stored on our servers. To calculate real solar yield for your customer’s postcode, we securely look up UK postcode coordinates and solar irradiance data via free public services (postcodes.io and the EU’s PVGIS database). No other customer information is sent anywhere.
After payment via Stripe you’ll be redirected back to the tool with your Starter plan active immediately. The watermark is removed from all PDFs, the daily limit is lifted, and your custom logo upload becomes available — no waiting, no setup.
Yes. If you subscribe at £9/month today, that price is locked in for as long as you remain a subscriber — even if we increase prices for new customers in the future. You can cancel at any time with no penalty through your Stripe billing portal.
You can cancel any time by emailing solarcalcuk@gmail.com and we will cancel within 24 hours. Or manage your subscription directly at billing.stripe.com using the email address you subscribed with. Cancellation takes effect at the end of your current billing period.
Yes — more than most installers realise. In UK solar owner communities, homeowners regularly report contacting 5 or more installers and receiving quotes that range from a one-line email to a detailed PDF breakdown. The ones that win the job are usually the ones that showed their working. SolarCalc gives you that edge in under 5 minutes.
