Add to your existing solution

Many people know the advantages of installing solar panels on your existing house or commercial premises (1.3 million people across the UK* to be exact!). But what people may not know is that on top of up to £500 per year savings solar panels can offer, adding a solar battery pack for solar panels to your exiting system can save up to 75% per year on your energy bills when combined with smart tariffs.

But the benefits don’t stop there. Solar battery storage gives you the option to store excess power generated by the solar panels, ready to be used during peak times or if not used, sold energy back to the grid. Under the Smart Export Guarantee (SEG) you can drive your energy bills towards net zero!

    There isn’t a one-size fits all when it comes to solar batteries. The size of your solar battery storage will depend on your existing solar set up with the more solar generated, the more capacity you’ll need to store the generated power. The average home uses 10kWh of electricity and the average solar system is 4kWp. For this a 5kWh is sufficient, or you might opt for a 10kWh system to make use of tariff integration and grid services.

    Yes! solar panels and a solar battery pack are most effective when combined, so if you already have a solar system, adding a battery is an excellent way to minimise your energy bills and cut carbon emissions.

    Solar battery storage prices can vary on a number of factors including amount of solar energy produced and the size of your house or commercial premises. The number of batteries needed would also impact the price.

    There is good news however. In the past number of years the price of solar batteries have reduced (nearly 50% less), making them more affordable to homeowners and a sensible investment.

    The suite of Duracell Energy products is distributed by a network of Approved Installers and Platinum Partners.
