Compare solar quotes against the bill they should be solving.
Two solar quotes can look similar but use very different assumptions. GridBeater keeps the bill in the middle: current spend, likely savings, bill after install, and the questions each quote should answer before you sign.
A cheap quote is not always the best quote, and a high savings claim is not always real. Your bill gives the comparison a starting point.
A buyer-side sanity check before the sales step.
Does the quote saving make sense compared with the current bill?
Does the proposed system direction fit the usage and tariff clues?
Is battery included for a bill-based reason, or mainly because it sounds attractive?
Look for hardware, warranty, exclusions, rebate handling, and site-work assumptions.
Common questions
Can I use this with two or three quotes?
Yes. Start by checking the bill. Then use the bill result to ask each installer the same questions about savings, system size, battery logic, and final bill outcome.
Can GridBeater choose the installer for me?
Not automatically. The safer first step is to understand the bill and quote assumptions, then choose whether you want a human check or installer introduction.
What if the quote looks good?
Then the human check can be faster. The goal is to confirm the logic, not create friction when the quote already makes sense.
