Introduction: Why Battery Storage is a Game-Changer for Solar Power
Solar power has become one of the most efficient and sustainable energy sources available. However, having sufficient solar generation for winter months in the UK can mean you have an excess of PV power in summer months and without a way to store the excess energy, businesses and homeowners can miss out on its full potential. Battery storage solutions for photovoltaic (PV) solar arrays provide a crucial advantage by allowing users to store excess solar power for later use, increasing energy independence and reducing reliance on the grid. In this article, we explore 10 benefits of integrating battery storage with your solar panel system.
1. Maximize Solar Energy Usage-increase your self-consumption
One of the biggest challenges with solar power is that energy production doesn’t always align with consumption. During the day, solar panels may generate more electricity than is immediately needed, and without storage, this surplus is sent back to the grid. A battery system (also referred to as an EESS (Electrical Energy Storage System) or a BESS (Battery Energy Storage System)) allows you to store this excess energy for use when the sun isn’t shining, such as at night or during cloudy weather, increasing the household use of your own self-generated power.
2. Reduce Electricity Bills
With battery storage, you can significantly lower your electricity costs. Instead of drawing power from the grid during peak hours when electricity rates are often higher, you can use your stored solar energy. Self-consumption of your generated PV power with a battery can increase from around 50% with solar alone to 95% when combined with battery storage. Many utility companies charge more for electricity during peak demand times, and by relying on battery-stored energy, you can avoid these higher rates.
3. Government Incentives and Financial Benefits
Until 1st April 2027 there is no VAT on new or retro-fitted Battery storage systems and Power Diversion units, saving 20% on the cost of installation. In addition, many electricity suppliers offer a SEG (Smart Export Guarantee) tariff, paying up to 15p/kWh for power exported back to the grid. For others, agile tariffs provide higher payments for power exported to support peak grid demand. It still costs more to buy electricity back again so increasing your self-consumption should still be your main driver, however, these financial benefits can help offset the initial investment costs, driving up the return on your investment and making the transition to solar storage more affordable.
4. Energy Independence and reduced Grid Reliability
With a solar battery storage system, you become less dependent on the national grid. Generating your own power to fuel your business premises or domestic home feels great! This increased energy independence gives businesses and homeowners greater control over their power supply.
5. Backup Power During Outages
Power outages can be inconvenient and costly, especially for businesses or households that rely on electricity for essential functions. With a solar battery storage system, you can also have a reliable backup power source that can keep your lights, appliances, and critical devices running during blackouts. This is particularly beneficial in areas prone to power outages, ensuring that you have access to electricity even when the grid goes down. Availability of backup power depends on equipment installed-if this is an important feature, be sure to mention it when obtaining quotes.
6. Environmental Benefits and Carbon Footprint Reduction
Using a battery storage system enhances the environmental benefits of solar energy. By storing and utilising clean energy you decrease the reliance on fossil fuels generated power, reducing greenhouse gas emissions.
7. Increased Property Value
Properties equipped with solar panels and battery storage systems are more attractive to both home and business purchasers. Increasingly, business owners and homebuyers are seeking energy-efficient properties with lower running costs, and a solar battery system can make your property more appealing, securing a higher price on the open market.
8. Better Efficiency and Smart Energy Management
Modern solar battery systems come with smart technology that optimizes energy use. Advanced monitoring systems, incorporating AI, allow users to track energy production and consumption in real-time, helping you make informed decisions to maximize efficiency.
9. Reduced Strain on the National Grid
Widespread adoption of battery storage reduces demand on the electricity grid, especially during peak times. This can help prevent grid failures and reduce the need for power plants to burn fossil fuels to meet peak demand.
10. Future-Proofing Against Rising Energy Costs
Energy prices are continuously rising, and the trend is expected to continue. By investing in a solar battery storage system, you protect yourself from future electricity price hikes by securing your energy supply now.
