One comparison circuit
Keep source documents beside you. Enter only what each installer wrote; “unclear” is useful evidence.
Total, kWp, battery, generation, savings, warranties, and included work.
Tool calculates cost per kWp and quote-provided simple payback, then flags unclear scope.
Download a comparison record. Ask installers to clarify; tool never selects one.

Compare two current written residential solar PV quotes. Keep inputs in browser and download your own record.
Why this comparison exists
CMA guidance recommends multiple quotes and written clarity on product, installation, taxes, funding, and extra work. Current MCS solar PV standards expose generation and self-consumption assumptions. SolarQuote Check puts entered facts beside each other; sources remain authority.
Before paying
Compare total price, system and battery size, quoted generation and savings assumptions, warranties, and whether enabling work is included or unclear.
No. It aligns values you enter and exposes differences. It does not rank installers or assess technical suitability.
No. The displayed figure divides quoted price by installer-quoted annual savings. It labels the result as a quote assumption, not a forecast.
