Battery Storage Solution

Power Everyday With Renewable Energy That You Can Use Day And Night.

Solar Battery Storage

Solar panels require sunlight to create energy, so as soon as its dark you'll be back using power from the grid. Having a battery means the surplus solar energy can be fed into the battery. The batteries are charged during the day by means of solar energy. The surplus solar energy is fed into the battery rather than being exported to the National Grid. This means that the batteries are always fully charged so that these can be put to use at night-time.

For the last 14 years we have specialised in the design, installation and commissioning of Renewable Energy systems, LED lighting system design and installation, Electrical Inspection & Testing, Battery Storage and EV charge points, De-stratification systems and all Electrical contracting from domestic to Industrial including repair and maintenance in Dorset, Hampshire and surrounding counties.

In the summer, when there is adequate solar energy, the home can run up to 3 weeks at a time without relying on the national grid. The StorEdge solution helps home owners reduce their electricity bills while maximising energy independence from the grid. StorEdge is compatible with Tesla’s Powerwall Home Battery, and is based on a single SolarEdge DC optimised inverter that manages and monitors PV production, consumption and storage. Unused PV Power is stored in the battery and utilised when needed to maximise self -consumption.

How Does Battery Storage Work?

Battery storage works by storing any unused solar energy your system generates throughout the day so it’s available for you to use at night just like you would any ordinary solar power.

Why Is Battery Storage Useful?

In recent years battery storage has developed into a must have essential for many families across the UK who are looking to invest in solar pv with the hope of finding a long-lasting storage back up alongside their system that utilises the energy produced throughout the day. This is something that could be incredibly useful when the sun goes down and is no longer available for evening use. Aswell as this more and more people are looking to solar as a way of reducing the number of harmful emissions they're releasing into the atmosphere, with solar comes the question how can I generate electricity in the evening when my solar system is unable to do this? That’s where we bring you battery storage.

Battery storage provides an easy and accessible way of generating electricity when solar cant and the two-work hand in hand. So watching tv, listening to music or anything else you have in mind is made easy.

Are Solar Storage Batteries Worth It?

Solar batteries are 100% worth every penny they cost as long as they’re used by people who are going to use them day in day out. Battery storage is an intelligent solution to a common and frustrating problem that homeowners often have. Being able to store energy in the daytime to use at night means you can carry on your normal routines without having to rely on your solar system.

Can You Power A Home With Battery Storage?

Battery storage devices can be used to power homes by using stored solar energy in the evening. However, just like you need to consider your households average electricity usage to work out whether you'll be able to power your home through solar energy youll also need to consider the type of battery storage device your going to choose. This will make a difference to whether you have the ability to power your home solely through solar. Batteries with higher energy capacities give you the freedom to store a larger amount of excess energy in them because their maximum energy hold is higher. We provide two different types of battery storage solutions including the Growatt storage solution and the Tesla Powerwall 2. The Tesla Powerwall 2 has a high capacity of 13kWh over twice as much as their first-generation Powerwall. Overall, yes, you can power your home with battery storage, but it takes a lot of financial considerations and planning as to how your current electricity usage might need to change to be able to do that.

How Many Batteries Are Needed To Power A House?

The number of batteries you'll need to power your house will be dependant on the size of your home and the amount of electricity your home Is using on average. Most average home sizes will only require one battery storage device, however, if your thinking of storing mass amounts of energy you may need to consider more than 1.

How Long Can A Tesla Power A Home For?

Tesla power walls can power a home for days at a time if need be, however, they aren’t designed for this purpose instead they act as a backup if the primary energy source is unavailable or not working. The Powerwall is also designed to substitute the solar array in the event of a power cut or anything similar

How Long Does A Tesla Powerwall Last?

Tesla power walls have a 10-year warranty. However, many customers have used their battery storage device for many years after this with no problem. It depends on how much you use it as to whether it will last you longer than 10-years or not. For instance if you only use your battery storage as a backup in case of a power cut or anything similar than your battery could operate for a lot longer after your 10-year warranty has finished, whereas if you’re a homeowner that regularly uses your battery storage day in day out then your Powerwall may not last for significant amounts of time after your 10-year warranty period is over.

How Much Will A Tesla Powerwall Cost?

Battery storage devices can vary in price so it's difficult to put an exact number on what yours will be at least until the required details are given to make these calculations. The price of your Powerwall will be determined on 2 factors; The average electricity usage your family consumes regularly as well as the size of your solar system. Powerwall’s are one of the more expensive battery storage products on the market however, there are plenty of benefits the Powerwall gives that you wouldn’t receive from any of the other battery storage devices on available on the market.

Can I Go Off-Grid With Solar Batteries?

The Tesla Powerwall 2, allows you to go off-grid with your electricity due to the large number of capacity it holds, however, you'll still need to work out the amount of electricity your home uses each month to know if going off-grid with your solar battery is viable.
