Solar panels can make a property more interesting to a buyer who wants to reduce the amount of electricity purchased from the grid, but their presence alone does not tell you whether the financial
case is strong.
A buyer viewing a home with an existing system should ask who owns the panels, when they were installed, whether there is battery storage and what paperwork is available for the installation. Recent
electricity bills, generation records and export payments can provide more useful evidence than a line in the property description.
For a buyer considering whether to install solar after the purchase, Stratford Energy Solutions guide to
what Martin Lewis says about solar panels
offers a useful way to assess the financial case. Household usage, roof suitability, export payments and payback all need to be considered rather than assuming panels automatically make a property
cheaper to run.
Export arrangements matter as well. The Smart Export Guarantee allows eligible small-scale generators to receive payment for electricity sent back to the grid, but tariffs vary between suppliers.
A buyer purchasing a home with solar panels should therefore understand both how much electricity the household is likely to use directly and what happens to the surplus.
