Store excess Electrical energy in Battery

for use at Night

BATTERY STORAGE

The way to overcome Solar's age-old problem!

Solar Generation seldom coincides with demand.  With the latest battery technology you can now efficiently store the excess energy from your Solar panels and use it when you need it most.

 

The graph below demonstrates the principle.  Peak generation from a Solar PV system depends on the weather but is typically around mid-day.  However the peak demand for energy in your property is mainly in the mornings and evenings.  As the graph shows, battery storage allows you to save surplus power generated during peak generation times for use during peak useage times.  It is that simple!

Proven new battery technology

Solar Storage Batteries allow you to store electricity generated by your solar panels during the day for use at any time when demand is greater than the electricity being generated at that time. This can be during the day, evening or night. Although a four-battery cabinet is quite large, about the size of a dishwasher, they are now both affordable and economically attractive. 

The saving comes from the difference in price. The current price (April 2020) of electricity that you buy from the grid is typically 15-16 pence/kwh whereas the price at which you sell your surplus electicity to the grid is only around 4-5 pence/kwh.  An average home in the UK, fitted with 16 solar panels, exports as much as 70% of its power to the grid.

 

Storage and FiT

Although solar panels themselves are a valuable asset, both financially and environmentally, you can increase the benefits of solar with a storage battery. Also, the installation of a battery does not affect any F.I.T. payments you may be receiving.

 

Save more with storage

Your storage battery charges up during the day and discharges stored energy when needed, most likely in the evenings which tends to be the peak time for energy usage. So, you could rely less on purchasing energy from your supplier at these times. There are even some battery manufacturers stating that you can shave an extra 50% off of your energy bill with a battery, when compared to just solar panels alone.

 

Be self sufficient

You could increase the self-sufficiency of your property and reduce your reliance on expensive grid energy. Some batteries even offer back-up electricity during power cuts and storms.
