Is the system the right size?

FREE UK SOLAR PANEL QUOTE CHECKER
Solar installation quotes can be difficult to compare. Fairbeam helps you understand the equipment, system details and important questions worth asking before making a decision.
Free to use. No sign-up or login. No obligation to request another quote.
A good solar quote should explain what you are buying, what is included and how the proposed system is expected to perform.
Check how many panels are proposed, their wattage and the overall system capacity. Ask how the installer arrived at that size for your household.
Find out the make and model of the panels, inverter and any battery. Warranties, performance and features can vary considerably.
Check whether scaffolding, bird protection, electrical work and other installation requirements are included in the quoted price.
Ask which electricity prices, payments for spare power and household use were used to estimate your savings.
There is no single price that every solar installation should cost. The total depends on system capacity, equipment, battery storage, roof access and installation requirements.
Comparing quotes by price alone can therefore be misleading. Two proposals may have different panels, inverters, warranties and included work. Before deciding whether a quote is reasonable, make sure you understand those differences. Read our step-by-step solar quote price guide.
Enter the details yourself or upload your existing solar installation proposal.
Fairbeam checks the available system information, identifies equipment where possible and highlights practical questions worth asking.

Before you sign
Practical guides for the quote you already have.
Compare the full system and installation scope, not just the headline total.
A practical checklist for the equipment, forecast, price and contract.
Work out what storage may add to the same solar installation.
A headline price cannot establish value by itself. Compare the system and installation scope, then ask about differences. Use the detailed like-for-like comparison guide.
Fairbeam cannot independently verify installation workmanship, roof suitability, certification, network approval, warranties or future savings. Confirm these with your installer and relevant organisations.
Ask which import price, export tariff, generation estimate and electricity-use pattern were used. Bill savings and export income are different. A battery can reduce exports as well as imports.
