One published rule, the same for every quote
- 1You enter four numbers from the quote: the system size, the battery size, the total price, and whether the SEAI grant is already off.
- 2We compare the price with one rule of thumb: €2,500 + €500 per kWp + €250 per kWh of battery, after the grant. Extras such as an EV charger add a printed amount.
- 3You get a verdict from Keen to Too dear, the sum behind it, and questions to ask the installer.
Rule v1, published 28 September 2026. Grant figures are for 2026. Budget 2027 on 6 October 2026 may change them, and we will date any change.

AskSolar is run by Dan Malone. He has solar on his own house and built the check so anyone can test a quote against one rule they can read.
Independent, plain-English solar help for Irish homeowners. We're not an installer and we don't sell panels.
Free for homeowners. AskSolar may charge an installer a flat fee if you ask us for an introduction and you accept it. Every quote is checked against the same published rule, and no installer can pay to change a verdict. The price check never sends your details to an installer.
