What we provide
Use the calculators to separate solar bill reduction, export income and payback. The quote checker asks about missing scope and inconsistent arithmetic. The existing-owner battery journey treats the original solar purchase as a sunk cost.
Articles use named sources and dated assumptions. Research-based guidance is distinguished from hands-on product testing, installer assessment and a surveyed design for your own home.
How the numbers are produced
One versioned model powers both calculators and quote comparisons. Direct use, exports, battery delivery and losses are accounted for separately. Annual inputs cannot establish half-hourly overlap or guarantee equipment life. Read the method and assumptions.
Your actual bills, an installer forecast and a manufacturer specification provide different kinds of evidence. Illustrative starting figures are examples you can replace. Source notes include review dates and limitations.
