Energy storage and backup power systems
Home batteries are booming in the UK. Compare costs, capacity, and brands like Tesla Powerwall and GivEnergy. Learn how tariff arbitrage and solar storage can slash your electricity bills.
TLDR: Home batteries cost £4,000-£10,000 for 5-13 kWh. They maximise solar self-consumption and enable tariff arbitrage (buy cheap, use during peak). Best value with Octopus Flux or similar tariffs.
TLDR: Home batteries cost £4,000-£10,000 and pay back in 7-12 years with optimised tariffs. Without smart tariffs, payback extends to 12-18 years. Here's the detailed maths.
