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 it. 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 the Tesla Powerwall 2 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.

    • Electric Vehicle Charger installed at your home or are able to have one installed
    • Solar panels and Powerwall 2 (Or a home suitable for this)
    • Residential electricity supply
    • You are eligible for the 11p / kWh tariff if you have:
    • Solar panels and Powerwall 2 (Or a home suitable for this)
    • Residential electricity supply
    3 What Are The Tariff Details?
    No daily standing charge on your bill 24/7 import rate of 8p / kWh for current Tesla vehicle owners and 11p / kWh for non-Tesla vehicle owners. The lowest flat rate tariff available in the market (as of October 2020) 24/7 export rate of 8p / kWh for current Tesla vehicle owners and 11p / kWh for non-Tesla vehicle owners for any electricity you export - up to 100% more than the highest flat S.E.G. tariff on the market (as of October 2020)
    4 Other FAQ'S

    What If I Don’t Have Solar Panels Installed?

    To be eligible for the Tesla Energy Plan, you must have both solar panels and Powerwall 2 installed. To install solar panels, ideally you’ll need a minimum clear space of 24 square meters – about the size of a parking space – available on your roof. The area should be free of shading from trees, chimneys or other buildings for most of the day to get the maximum energy generation from your panels. A Tesla Energy Advisor or your local Tesla Powerwall Certified Installer can help assess system sizing and provide a quote on solar and Powerwall.

    I Already Have Solar And Powerwall. What Is Next?

    You can transfer onto the Tesla Energy Plan straight away by switching your retail plan. You need a smart meter in your home; however, Octopus can arrange to have one installed at no charge.

    Do I Have To Own A Powerwall To Sign Up?

    Yes, you must own a Powerwall 2 to sign up. The Tesla Energy Plan combines solar with Powerwall to maximise your savings. If your Powerwall installation is already scheduled, we will manage the tariff transfer process once your system is installed.

    How Much Capacity Do I Need and What Does It Mean?

    With renewables becoming the future of electricity amongst people desperate to cut carbon emissions and save on energy bills battery storage is the perfect solution. Solar energy is a natural renewable power supply that allows you to store the energy your solar PV system produces and use it at times when your solar is unavailable. For instance in the event of a power cut having battery storage means you would still be provided with electricity for hours after and sometimes even days depending on the type of device you purchase, whilst other households wouldn't have this option. Battery storage is also commonly used as a backup for evenings or when the sun isn't as present in the winter times giving homes ultimate flexibility.

    The “capacity” of a battery is the amount of kWh energy that is available to be stored within that device. The capacity load your storage device can hold varies from product to product. Often cheaper solutions will have a lower capacity load than ones that are slightly more expensive such as the tesla Powerwall. Tesla Powerwall 2 has a large capacity load to give customers ultimate flexibility with their energy.However, some households simply do not need a high capacity load for their home and their average energy usage would be more suited to a storage solution with a reduced capacity. For this we recommend the Growatt energy device.

    When it comes to finding out how much capacity you’ll need for your storage device it’s the amount of “usable” capacity a battery has that you're looking for rather than the “total” amount its able to store. The total storage size of a battery will never be fully run down instead your battery will only exhaust its usable capacity to protect it from internal damage. It's important to know this so you don’t get the wrong information about a product because its not got the capacity load you thought it did.

    Frequently Asked Questions

    Tesla web

    Is It Worth It For My Home?

    Solar storage batteries are used to utilise the energy your solar produces in the day with the ability to store it and use it later on. At Empower we know how helpful this is for any homeowner looking for a solution to a frustrating problem with the goal to be self-sufficient all day long, without the need to be so reliant on your solar system.

    Can You Power A Home With Battery Storage?

    Powering your home on Battery storage is possible however, it involves multiple considerations to know whether its a smart and viable decision for your household. Some battery's have lower capacity loads than others so if your looking to run your home's electricity on stored solar energy you'll need to consider investing in one with a high capacity that gives you the freedom to do this. We offer two very different but equally intelligent 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. Before rushing into anything researching the different battery storage devices available on the market to get an idea of price ranges, benefits and possible problems you may encounter with them is important.

    How Many Batteries Are Needed To Power A House?

    This will depend on your households electricity usage per month and the size of your home. Most homes require no more than one battery storage device to power their home, however, if you're looking to store large amounts of energy for backup supply you may need to look into investing into more than 1 battery storage device. Talking to your expert installers will give you a better idea of how much energy you're using if your not sure and the size and amount of storage you'll need to power your home.

    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 complications. It all depends on regularly your household use it as to whether youll get longer than 10 years out of your device. For instance if your only using your Tesla Powerwall as a backup in case of a power cut or anything similar then your it may still operate perfectly even after your 10-year warranty has finished, whereas if you’re a homeowner that regularly uses your Powerwall then its less likely to last over the 10 year warranty period than a Powerwall used less frequently.

    How Much Will A Tesla Powerwall Cost?

    The price of your Powerwall will be determined by your family's average electricity consumption as well as the size of your solar system. Powerwall’s are one of the more expensive battery options on the market however, there are various benefits the Powerwall provides customers that most other devices on the market wont.

    Can I Go Off-Grid With My Battery?

    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.
