Spain produced MORE solar this August… so why were electricity bills HIGHER?
It sounds backwards, doesn’t it?
Solar generation in Spain was 27.6% higher than a year ago, yet the average August bill for households on the regulated tariff was almost 20% higher.
Part of the reason is surprisingly simple: solar produces most during the day, but our electricity use doesn’t stop when the sun goes down. VAT on electricity is also back at 21% after being temporarily reduced.
Come evening, we’re still running air conditioning, cooking dinner, charging cars and using appliances. When renewable energy can’t meet all that demand, the grid has to rely more on other, more expensive sources.
And this is where having your own solar - particularly with a battery - starts to make a lot of sense:
☀️ Produce your own electricity
🔋 Store what you don’t use
🌙 Use it later when the sun goes down
That doesn’t mean every home needs a battery. Some do, some don’t. It really depends on when and how you use your electricity.
But the bigger point is simple:
You can’t control what electricity prices do next. But you can reduce how much electricity you need to buy in the first place.
Curious what that could look like for your home? Send us a recent electricity bill and we’ll take a look at your usage and tell you what genuinely makes sense - solar, battery, both, or neither.
No jargon. No hard sell. Just straightforward advice.
