Savings grow as energy prices in Great Britain rise and cost of panel installation falls, analysis finds

Households in Great Britain’s cloudiest regions could still save more than £400 a year on their energy bills by installing rooftop solar panels, research has found.

Rising wholesale energy prices mean the potential savings from a home solar panel system have climbed in recent years, as the cost of installation has continued to fall, leading to increased demand.

A financial model that could cut the cost of installing solar panels for many homeowners is welcomed by Alexis Abramson

The UK proposal to use “solar bonds” to make rooftop solar more affordable is a smart solution to a fundamental problem: the rising cost of capital (Cut cost of loans for solar panels on UK homes, ministers urged, 21 August).

A household that can pay for solar upfront saves money from day one. For everyone else, high-interest financing can consume much of those savings and ultimately deter people from installing the technology. A solar bond structure changes that equation: investors receive a modest, guaranteed return, and homeowners get access to cheaper capital. Because the loan is attached to the property rather than the individual, there’s no issue if the person moves.
