How Solar Panels Affect Your Electricity Bill
-
Self-Consumption: Solar panels convert daylight into electricity, which powers your home (load) during daylight hours through the fuse board. This reduces the amount of electricity you need to purchase from the grid throughout the day and night time.
-
Exporting Excess Energy: If your panels produce more electricity than you use, the surplus can be exported back to the grid. Under the Smart Export Guarantee (SEG), energy suppliers pay you for this excess energy, providing additional savings.
-
Battery Storage: Adding battery storage allows you to store unused solar energy for use during non-sunny periods or at night, further decreasing your grid electricity usage.
💷 Potential Savings
Average Savings (No Battery): A typical 3-bedroom UK home with a 4 kWp solar system can reduce its annual electricity bill by approximately 40%, lowering it to around £236 per year.
With Battery Storage: Incorporating a battery can increase savings up to 90%, potentially saving households over £1,000 annually.
Export Earnings: Through the SEG, you can earn money by selling excess electricity back to the grid, with rates varying by supplier, Octopus offer a timed export scheme, standard rate is 15p high rate between 4pm – 7pm is 32p.
🏡 Real-Life Example
Judith Leary-Joyce from St Albans installed solar panels and a battery system, reducing her energy bills to nearly zero and earning approximately £600 annually by exporting surplus energy back to the grid. thesun.co.uk+1sunsave.energy+1
Mr Solar has 100s of happy customers all over Norfolk and Suffolk who are happy to talk to you about there experience and savings on there Solar PV battery systems from Givenergy, Tesla, Solax and Sunsynk who we are approved installers for.
🔍 Factors Influencing Savings
System Size & Efficiency: Larger or more efficient systems generate more electricity, increasing potential savings. You can check what you need by booking a free Solar PV battery survey.
Energy Usage Patterns: Homes using more electricity during daylight hours benefit more from solar energy however, if you are not home and the battery is full you will be selling spare electricity to the grid.
Location & Daylight Exposure: Homes in sunnier regions or with south-facing roofs typically generate 6% more solar power than roof with East and West facing roofs, so you may need more Solar panels.
Tariff Rates: SEG rates and electricity prices vary among suppliers, affecting overall savings.
