Solar powering sodium-ion batteries and VPPs

VPP vs Higher Feed‑in Tariffs: Which Puts More Money Back in Your Pocket?

The old solar story is straightforward: export during the day and collect your feed‑in tariff. The new story adds nuance. When everyone exports at midday, prices sag. When everyone needs electricity at dinner, prices soar. A VPP is built for that second moment.

This isn’t a moral crusade against FITs. They’re useful. But they’re not designed to target scarcity. A VPP is. It sits quietly in the background, watching the market’s pulse. When a hot evening bites or a storm knocks out supply, it nudges your battery to export precisely then — and only from energy you’ve chosen to make available.

If you want proof rather than promises, run your own experiment. Take three months of ordinary life with a sensible reserve and let the VPP do its thing. Compare credits and bill reductions to the same period last year. For many households, the difference isn’t just the number on the invoice. It’s the feeling that the system finally works with the real world, rather than against it.
