Solar Panel Batteries – Solar Panel Storage
What is the Technology?
Why Solar Panel Batteries? Solar panels are great, really great. They make electricity from the sun’s energy and once installed, they do it for free for at least 20 years. Solar and other renewables are on track to provide 20% of the EU’s energy share by 2020. For the first time, on Saturday 25 March 2017, electricity demand in Great Britain was lower during the afternoon than it was overnight due to high solar generation.
However, the drawback is that the biggest demand for electricity is 4pm – 8pm weekdays from November – March and you will have spotted the problem with that. It’s generally dark in the UK at these times. Another exciting development – electric vehicles like the Tesla and Nissan Leaf could actually be adding to this problem. People generally drive to work in these cars and then arrive home within this peak demand time and plug their car in to charge it.
Could the answer lie with Solar Panel Batteries? The answer could be “YES!”
Homeowners with solar panels on their roof can charge their Solar Panel Batteries during the day when less energy is needed in the home. Because of the way that solar is set up, it flows first to the house where it’s installed and any excess is diverted to the grid. This energy could be captured in the home and stored in a battery. The Solar Panel Batteries will then provide energy to the home for the evening.
In the graph above, the blue is the solar pv production, the light green is the battery charging and discharging and the grey is the load needed to power the house. As you can see, in this small system, the majority of the load of the house is met by the battery or the solar pv apart from between 4am and 6am.
What are the main benefits of having a solar panel battery storage system?
- Independence from the grid: you can use the energy that you generate on your roof rather than sending it to the grid
- Car Charging: you can charge your Tesla or Nissan Leaf from your own green energy
- No impact on Feed in Tariff or Export Tariffs you are already receiving from the government
For customers who already have solar panels and a working inverter, solar battery storage can be added as a simple, easy bolt on to your existing system. Sustainable Solar Solutions install Mercedes Benz and LG Chem Lithium Ion batteries. These units are around 60cm by 50cm and connected to the homeowner’s inverter via a charge controller.
If you don’t have solar installed, we can install solar panels and a hybrid inverter, which is a charge controller and inverter combined, together with the battery. We recommend the Goodwe Hybrid Inverter in this instance and an LG Chem or Mercedes Benz Solar Panel Batteries.
Solar PV Panels
Solar Photovoltaic Panels or Solar PV, take energy from the sun delivered as light and turn it into electricity to power your home.

Here are the answers to a few Frequently Asked Questions:
1. Which angle should my roof be at for solar panels?
The answer to this really depends on the season. In the winter a 14 degree angle would be best and in the summer, 62 degrees. Since it’s not usually possible to re-position your roof, an angle of between 35 – 40 degrees is best.
Panels will perform at any angle and it is possible to mount them on a vertical surface on a flat roof, we recommend an angle of 15 degrees as this allows self cleaning without requiring too much ballast to hold them onto the roof.
2. Roughly how much will it cost?
A large domestic installation will cost around £6,500 and bring in around £800 per annum in savings on your electricity bills and Feed in Tariff subsidy. This brings the payback time in at around 8 years.
3. How much space do I need?
A standard panel is 1.6mx1m and panels on a pitched roof should be around 60cm from the roof edge to avoid wind-lift. On a flat roof, panels will be on angled frames and you should allow 50 – 70cm between panels to avoid them shading each other.
4. What is the environmental benefit?
The amount of carbon dioxide (CO2) generated to produce and install a solar panel gives it a carbon footprint of 72gCO2e/kWh compared with 487 for gas or 870 for coal fired power stations . Carbon dioxide is a major contributor to climate change.
