Less than a year ago, in August 2023, we installed a 4.8kWh Solar Battery at a cost of £2,900. Whenever I talk about the upfront capital costs of solar power, people rightly want to know what the payback period is. Well, after less than 10 months, the battery has given us 1MWh. To put that in to context, the average UK household uses about 3MWh per year. So (again, very roughly) over a third of our electricity use this year has come from the battery. But where does the battery get its …

I have upgradeitis. If something newer and shinier comes out, my stupid monkey-brain compels me to buy it. Seven years ago, we installed a solar battery. It was part of an experimental project which looked at creating a community power-grid, so it came at a subsidised price. As I explained to BBC Click, the 2kWh capacity was reasonable - but I expected the future would bring higher capacity, cheaper costs, and smaller sizes. But, after 7 years the battery was starting to show its age.…

A few years ago, I took part in a local trial to install a solar battery in our home. The battery was excellent - and made a reasonable difference for our energy use. Sadly, last year, it died. It was prototype hardware, and these things happen. Moixa offered to replace it with an updated model - which was generous of them. While we were waiting for the new model to come in to stock, we moved house. Then COVID happened... Anyway, long-story-short, we now have a shiny new 2kWh battery…

Even in the depths of British winter my solar panels'll still happily convert what little sunlight we get into delicious, free-range, organic electrons. Nice! Most of our domestic energy use is in the evening. So, when I'm out at work I can schedule the tumble dryer, robot vacuum cleaner, and WiFi rice-cooker to consume energy when the sun is shining. The rest is sold back into the grid for my neighbours to use. Wouldn't it be great to capture that energy and use it to power my lights and…
