Solar savings guides & honest comparisons

Most solar "content" is really a sales funnel with a blog attached. These guides aren't. Each one takes a genuine money question a UK homeowner asks — usually a comparison, because that's where the honest decision actually gets made — and works it through with real 2026 numbers, the assumptions on show, and the downsides stated plainly. Where solar loses the comparison, we say so.

Every figure here uses the same dated inputs as the rest of the site: the Ofgem price cap of 26.11p/kWh (July–September 2026), a 12p export rate (Octopus Outgoing, as at July 2026), and roughly 950 kWh of generation per kWp a year — all checked against Ofgem, the Energy Saving Trust and gov.uk, as explained in how we check our numbers.
