Solar PV & Battery Packages
With a solar PV and battery package, you can store energy that you generate from the sun during the day and use it in the early mornings and evenings when you would normally have to buy energy from the grid, thus minimising how much energy you need to purchase. If you also combine this with an agile energy tariff from Good Energy, you can ensure that you are always buying the cheapest possible energy based on your typical usage.
How It Works
Saving money with Solar PV and battery packages
Typically, people are paying between 15p and 20p for electricity. By generating your own renewable energy with solar panels for example, you reduce the need to buy electricity at ever increasing prices – that’s already a big win!
Then, if you are using more of the energy you generate on site, you will get a greater return. For example, a typical domestic system of 4.5kW with 80% on-site usage will generate an average of 10% return, as well as over 2.1 tonnes annually of carbon reduction.
Increasingly, batteries are playing a more important part in renewable energy, enabling you to purchase energy on much cheaper tariffs at off-peak times (often just 4-5p in comparison to the higher typical rates of 15-20p), which means you can store and use that power for your vehicle, home or business use during the day to offset more expensive power. In conjunction with solar, the justification looks even better as the solar panels can also charge up the batteries, helping to provide free energy at all times of the day.

Frequently Asked Questions
Planning permission is not normally needed if you are planning a roof mounted system up to 1MW in size unless your property is a listed building, located in an Area of Outstanding Natural Beauty (AONB), a conservation zone or a national park. Further information surrounding planning permission requirements for solar installations can be found on the Planning Portal.
A cycle is one complete discharge and one complete charge. In reality, the battery will not work in this way. A battery might only discharge 40% and then recharge 40% given the average demands on the system. This would be 2/5th of a cycle. Often battery manufacturers will warrant the battery for the number of cycles and therefore it is important to work out how many kWh your battery will delivery over it’s warrantied lifetime based on your average cycle.
Perhaps the most important question is to ask what your likely future requirements might be. For example, are you planning to have EV charging? A larger capacity system can keep the house or business premises running and charge EV vehicles overnight. Grid trading is also an exciting option. Larger battery systems will mean more charging at lower rates and more to sell back to the grid at peak rates.
