We ran out of battery power overnight, for the first time since the 4th April 2026.
We have spent 16 weeks off grid.
In that entire time, we have imported just 60.1kwh of electric.
That's an average of 0.5kwh per day or roughly 14p worth of electric.
But we still pay 70p per day in the standing charge for electric.
The standing charge is 5 times more expensive than the electric we are using at the moment.
Despite all of that, it's actually been a poor year for solar compared to last year. With generation actually being down by 10-15%... Heatwaves and perfectly clear skies, are not actually good for solar generation because the heat reduces the efficiency of the solar panels.
We should have produced in the region of 680-700kwh a month for May & June based on the number of clear sky days. Instead we generated 550ish. Instead of generating 28-29kwh per day, we were generating 23-24kwh.
But that 22-24kwh per day has been more consistent. With the avg per day for July being 21kwh, vs 18.8kwh for May and 18.3kwh for June. We didn't use more, but we did export a little more.
