Does Storing Solar Electric Power as Hot Water Make Sense?

Does Storing Solar Electric Power as Hot Water Make Sense?

Back in 2009, Lloyd argued that solar hot water should be much more of a priority than solar electric (PV) . The reason for that was pretty simple—the sun is really good at heating liquids, whereas using electric power to do the same job is not a particularly efficient transaction. So I am a little up in the air about a new product launched in the UK called Engensa Solar24 which claims to help owners of solar electric arrays to maximize their returns by converting excess electricity into hot water: Engensa’s first smart home energy product, Solar24 automatically diverts excess electricity produced by solar panels to a customer’s hot water tank rather than exporting it to the grid. Typically, around 50% of home solar electricity is used on site, whilst the rest is exported back to the grid. Now, with Solar24, homeowners can use every hour of solar electricity they generate,...
