With energy prices on the rise, many households are looking for smarter ways to use their solar power, and that includes keeping homes warm after the sun has gone down. The good news is that with the right setup, you can store solar energy in the day and use it for heating your home in the evenings and overnight, even in the depths of winter.
Solar photovoltaic (PV) panels convert sunlight into electricity during the day. Even in the UK’s cloudier months, a well-sized solar system can produce a significant amount of clean, free energy.
If you are home all day, some of this electricity will be used instantly. On sunny days, you will often have more than you can use in real time, and that’s where storage comes in.
Without storage, surplus solar power is simply exported to the grid. A home battery storage system changes that by storing the excess electricity, so you can use it later.
Modern home battery storage systems can hold enough energy to keep running your lights, appliances, and heating long after the sun sets. It is like your own personal energy reserve, allowing you to use solar power on demand, 24 hours a day.
ELKATHERM® electric radiators are a perfect match for stored solar energy. They contain a smart ceramic fireclay core, which heats up in minutes and stays warm for hours with minimal top-ups. They work perfectly paired with solar PV and home battery storage, giving you consistent, comfortable warmth all day long.
In winter, solar production naturally drops, meaning your batteries may not fully charge from sunlight alone. That is where cheaper ‘off-peak’ tariffs can help.
Setting your battery to charge during these low-cost periods can help you fill the gap when solar generation is low. Heat your home using low-cost electricity rather than expensive peak dates, and keep your batteries topped up and ready for the day ahead.
Many of our customers combine both, charging their batteries with off-peak power all year to make the most of the cheaper rates of electricity.
If you live in a property that is not suitable for solar panels, such as a flat or apartment, we can install home battery storage to enable you to make the most of these cheaper off-peak tariffs. There is no need to have a solar array on the roof.
A typical day could look like this. In the daytime, your solar PV powers your home and charges your batteries. In the evening, your ELKATHERM radiators run from the batteries stored energy. The batteries top-up overnight when electricity is cheapest, so you wake up to them fully charged and ready to use throughout the day.
The result? Lower energy bills, reduced carbon emissions, and a home that is warm and comfortable without worrying about whether the sun is shining.
Installing a full HeatElectric system – solar PV, home battery storage, ELKATHERM® electric radiators and a Sunamp water heater – plus making use of off-peak electricity tariffs – allows you to heat your home more affordably and sustainably all year round.
