A home battery completes your solar investment. Without storage, you export surplus power at low feed-in tariff rates and buy it back at full retail — often paying 3–5× more. Compare 8 home batteries available in Europe by chemistry, capacity, cycle life, and price.

A typical European home uses 10–15 kWh/day (lower than the US due to smaller homes and higher efficiency standards). For overnight backup (6pm–8am), you'd need 6–12 kWh of usable capacity. Most home batteries are 10–20 kWh — one battery covers the average European home for one night.
Yes, in several countries. Germany's KfW 270 loan covers battery storage alongside solar. Italy's Superbonus includes battery storage. Several countries offer 0% VAT on battery installations. Check our country incentives pages for up-to-date regional programmes.
Total capacity is the battery's full storage. Usable capacity is how much you can actually use — most batteries keep 5–10% in reserve to protect battery chemistry. Always compare usable capacity, not total.
LFP is the better choice for most European homes. It lasts longer (3,000–6,000+ cycles vs 2,000–3,500 for NMC), doesn't thermal-runaway, and can be fully discharged safely. See our full LFP vs NMC guide for details.
