What is Battery Storage?
Battery Storage involves installing a large domestic battery in your home (usually the garage) that you charge. This holds electricity which you can then use throughout your home as and wen you need it.
Without battery storage, electricity that you have generated through your solar panels that is not being used will automatically be exported to the national grid. Battery storage stores the unused energy that is generated meaning you can use it whenever you want.
Battery Storage technology is playing a key part in helping homes and businesses to reduce their carbon footprint and ensure that as much of their electricity usage is powered by green energy, even when the sun isn't shining.
There are two main ways to use Battery Storage
1
With Solar Panels
Your domestic battery would store any solar power that you didn't use at the time it was generated for you to use any time you needed it.
2
With Off Peak Tariffs
You could charge your domestic battery when your energy tariffs are at their cheapest (during the night) and use that power during the day when you needed it.
Benefits of Battery Storage
#1
Reduces the cost of your monthly energy bills
It means you will mainly be using energy you have generated yourself and so will dramatically reduce the amount of energy you will need from your supplier.
#3
No wasted electricity
Approximately 50% of the electricity that many homes produce through solar is lost as it isn't used at the time it's generated.
A battery will store this energy for you to use whenever you need it.
#2
Helping to save the planet
When combined with a PV Solar System it reduces your carbon footprint and ensures that as much of your electricity is powered by green energy.
#4
No more power outages
Most modern battery systems offer coverage during power cut/outages.
What sized Battery Storage system should I get?
A typical home may use on average around 8kWh of electricity per day, but battery storage systems can now store upwards of 20kWh so you would naturally assume that having the biggest system you can fit would be the better option right?
Well yes, and no!
Ideally you would be looking at a system that will at least cover your overnight usage so that it is ready to be recharged when the sun comes up the next day. However, there is no point in having a battery storage system that is oversized and will not be fully charged by your Solar PV system in the time it has of useable daylight.
With a battery storage system that is designed around your usage of electricity and your solar PV installation we can help you find the right fit for you and your property.
Brands we work with
Island mode or
Emergency Power Supply (EPS)
It’s a common misconception that if you have a full charged battery storage system that it will mean your property stays on in the event of a power failure, but unless you have a system that incorporates and has been set up to run in Island Mode or utilise the EPS system you will have no power, despite having useable power stored within your battery system.
We can discuss your requirements during our site visit and explain in detail how this might work for you as there are many options available from whole house coverage to having individual circuits being supplied power, like lighting and a fridge freezer for example.
Its important to understand that in some cases there will be additional work needed to fully utilise this system and not that all inverters have this capability. For more rural clients this may be more important than those of live in towns where power outages are extremely rare occurrences.
