Professional Solar Quote Generator for MCS-Certified Installers
Fill in your details below to generate your first professional PDF quote — takes under 2 minutes.
Enter your company and MCS certification information. This will appear on the final quote.
Required by consumer law to appear on the quote's cancellation-rights notice and cancellation form.
How a customer should raise a complaint with you directly. Shown on the quote alongside how to escalate to MCS.
If you hold Consumer Code membership, its dispute resolution route is shown as an additional option alongside MCS's own complaints route.
Accepted formats: PNG, JPG, SVG. This will appear at the top of the generated quote.
Enter the customer's name, contact details, address, and quote reference information.
Auto-generated reference. You can edit this if needed.
Enter the technical specification for the solar system, including panels, inverter, battery, and grid connection.
Auto-calculated as the total across your roof sections below
Overrides the dropdown above when filled. Negative = east of south, positive = west of south (e.g. -20 for just east of south-facing, 60 for between south-west and west).
Pitch and orientation are used to fetch a real solar production estimate from PVGIS in Step 5. Add another roof section if some panels face a different direction or pitch (e.g. a hip roof or dormer).
Total usable capacity across all units (from the product datasheet, MGD 003 §4.5) — drives the self-consumption-with-battery figure below.
G98 applications are typically free. G99 and Fast Track G99 may carry a fee.
Defaults to £0 for G98. Update if a fee applies.
Percentage added on top of material costs. Default is 20%.
Add labour costs, optional extras, and warranty/protection options to include in the quote.
Enter the estimated performance figures for this system. These will be shown to the customer in the quote.
Calculated automatically using the official MCS Kk tables (MIS 3002 Appendix B) for the postcode (Step 2) and roof section(s) (Step 3) already entered. This is the compliance-required performance estimate shown to the customer.
1.00 = no shading. MCS shading assessment is manual, on-site installer input — this field is never auto-filled. Starter/Pro can show an approximate estimate below from aerial data as a starting point only, never a substitute for an on-site assessment.
Required alongside the MCS yield estimate above (MIS 3002 4.1.2). Calculated per MGD 003: Solar PV Self-Consumption, using the official MCS lookup tables — not a flat assumption.
Default 3,500kWh is the UK mean domestic consumption (MGD 003 §4.3.5) — use the customer's actual annual usage from a recent bill if known.
Ask the customer which best matches their typical weekday pattern. If unknown, MGD 003 §4.2.2 specifies "In half the day" as the default.
Pre-filled from the MGD 003 lookup tables for the inputs above — edit to override.
Remainder of the MCS annual yield not self-consumed — feeds the SEG Year 1 Total Returns below.
Optional additional estimate using a different methodology (EU JRC PVGIS). Shown alongside, not instead of, the mandatory MCS estimate above.
Secondary/additional estimate only — shown alongside, not instead of, the mandatory MCS figure above. Does not drive the saving/payback/CO2 figures below.
Based on your postcode's solar data (PVGIS, EU JRC)
Default: Ofgem price cap — edit if your customer has a different tariff.
Self-consumed kWh (MCS annual estimate × Self-Consumption % above) × the electricity rate above — see the Self-Consumption section for the assumptions behind this figure.
Based on the mandatory MCS annual estimate and current electricity rate — actual payback may vary with future price changes.
Based on the mandatory MCS annual estimate and grid carbon intensity (National Grid ESO), approximated by nation (England/Scotland/Wales) from the postcode.
No standard default exists for SEG (unlike the Ofgem import price cap) — real tariffs range roughly 3-16.5p/kWh by supplier. This is a rough placeholder; check and update against the customer's actual SEG tariff before quoting.
Exported kWh (from the Self-Consumption section above) × the export rate above.
