Our calculations for Sunsave Plus solar

• Our example is a four-bedroom family home in Essex using 4,000kWh of electricity each year with a 7.1kW solar panel system and a 5.2kWh battery.
• This system generates 7,097kWh of electricity from solar each year, using 37% at home and selling the other 63% to the grid (earning up to 27p per kWh through the Intelligent Octopus Flux tariff).
• On average, this household pays £93/month on its electricity bill, but the savings and export income from solar means it falls to -£39/month (so the property is actually now earning money). Taking into account the £99/month Sunsave Plus payments, the household's total outgoing on electricity is now £60/month - a £33/month saving. In a year, this household now spends £720 on electricity instead of £1,116, saving £396.
• We’ve calculated the previous energy bill using the July 2024 Price Cap. With Sunsave Plus, the savings from grid import and export are calculated using the Intelligent Octopus Flux tariff.
• Savings are calculated using System Advisor Model (SAM) which takes into account smart battery controls to maximise export savings.
• This system would also save 1.63 tonnes of CO2 each year, which over 25 years is equivalent to 41 flights long-haul flights
