Our main solar install has now been active for three years. Although the beginning of this year under performed compared to the same time in 2025, we're currently in the middle of a heatwave and the pounding sun has driven yields up at the last minute. This post is a quick look at our solar performance over the last 12 months. Changes This Year There have been a couple of relevant changes this year: In April, I added a west facing balcony solar kit providing an additional 0.8 kWp A couple of weeks ago, I changed the way that I calculate savings so that the numbers more closely represent what we would have paid if we didn't have solar Total yield Over the last 12 months, the panels generated 2.92 MWh, bringing the lifetime yield to 8.3 MWh.
