Having a solar cell generating electricity to power your home can really help save you money, but it is not without its limitations. The most striking one is the fact that solar panels can only produce energy when there is sunlight. On cloudy, overcast days, in the dark or at night, you may find yourself having to buy energy from your electricity provider. Solar batteries help resolve this issue, by allowing you to store energy generated by your solar panels during the day, to be used at other times. This means you have free electricity powering your home round-the-clock.
Make the Most Out of Your Solar Panels
Solar batteries allow you to use more of the electricity produced by your solar panels, and as a result save you money on energy bills. It is estimated that you can reduce the amount of money you spend on electricity from your provider by 35%. Additionally, since the Feed-in-Tariff (which enables owners of renewable energy technologies to sell extra electricity back to the National Grid) rates were cut dramatically by the government in January 2016, you would actually be saving more money in total by storing any excess electricity generated in the day with a solar battery, and using it overnight.
All About Solar Batteries
Solar batteries are very low maintenance in terms of upkeep, and have a massive storage capacity, so you can really make the most of your renewable energy. All homes that already have solar panels could benefit from a solar battery, because otherwise energy generated in the day that doesn’t get used just goes to waste. There are two types of solar batteries – AC (connected to your solar panels via the electricity meter) and DC (connected directly to the solar panels, before the electricity meter).
Just like the solar panels themselves, solar batteries do require a large upfront investment. Though in the long-term there is very good ROI for solar batteries, the initial expenditure of anything between £2,500 to £6,000 is considerably high. Further to that, the solar battery would most likely need replacing during the lifetime of your solar panels, so it isn’t necessarily a one-time-only purchase. Another weakness of solar batteries is the amount of space they take up; they tend to range from the size of a microwave to a small fridge, so storage is certainly a factor. Smaller batteries can be mounted on the wall, but larger batteries will have greater capacity for storing energy, so it depends on what is best for your household. The solar battery storage capacities usually range from 1kWh to 14kWh.
The solar battery industry is still new, but is growing at a rapid rate. Today, some solar panel installers will offer deals that combine the solar panels with a solar battery, which may be a good way to save money overall on that initial investment. You want to choose a trusted and qualified professional to advise you about solar batteries, since if one is fitted with incorrect voltage capabilities or is the wrong size, that can be a serious hazard for your home.
