Tesla’s top-of-the-range battery storage system is still one of the most expensive on the market. It has a huge 13.5kWh usable capacity and can even keep you up and running during a power cut. But how long does a Tesla Powerwall battery last? And does this mean it’s worth investing in one?

The Tesla Powerwall 2.0 comes with a 10-year warranty. But Tesla says that it should last way beyond this – at least 5 years longer. The standard warranty says that it should work at 70% capacity for the full 10 years – so if it loses more than 30% of its storage capacity within that time, it should still be covered.

While the Tesla Powerwall does last a long time, it has a large capacity that most average households won’t require, and it’s a costly option. After installation, the Powerwall 2.0 will set you back between £6,500 and £9,000, so ideally you want it to last past its 10-year warranty.

Before you splash out, consider the size of the solar panel system you want to install or you already have. Will it generate enough electricity to make it worth storing in the Powerwall? If not, are you expecting to upgrade your solar panels to a larger system in the future? If you are, then it might be worth investing in a Powerwall. It might also be better to wait until you come to upgrade your solar panels – the solar battery price trend is going the same way as solar panels, so they will probably continue to decrease in price as more people adopt the technology.

The cost to charge an electric car in the UK varies between home, work and public charging.

For a typical electric car with a 60kWh battery and ~200 mile range:

• Charging at home: Costs about £9.20 for a full charge. *
• Charging at work: Many employers will install workplace charging points and typically offer free access throughout the day.
• Charging at public locations: Public chargepoints at supermarkets or car parks are often free to use for the duration of your stay.
• Rapid charging: Rapid charging points are normally found at motorway service stations and typically cost £6.50 for a 30 min, ~100 mile charge.

Charging an electric car at home costs about £9.20 for a full charge* and is the most convenient and cost-effective way to keep your car fully charged. Most drivers will charge their electric car overnight, waking up to a full battery every morning.

Average domestic electricity rate in the whole of the UK is about 17p per kWh.

Fully charging a 60kWh electric car will cost between £9.00 and £9.90 (depending on where you live) and give you about 200 miles of range.

* Costs calculated at 17p/kWh based on usable battery is ~54kWh (90%).

There are two different types: flat plate, where lots of thin tubes carry water through a flat absorber panel, and evacuated tube, where vacuum glass tubes capture the sun’s energy directly. There is little difference in performance between the two but evacuated tube panels do more obviously extrude from the roof.

The importance of selecting the right size battery for your home simply cannot be overemphasized. A lot of home and property owners are facing this challenge and understandably so. Selecting the right battery size for your needs depend on a number of factors which includes your motive for adding a battery, your electricity usage, your budget as well as your panel array size, be it new or existing. In this post, we’re going to take you through some of these factors to help you determine the right battery size for your home or property. Let’s take a look!

• Your motive for getting a battery. While most people purchase a battery to wipe out their need to purchase electricity from the grid with the hope of making some savings, others add a battery so as to enjoy backup power. There are also some who just needs it to power their home with solar energy. It’ll not be economical to size a battery to effectively take you off the grid, but if your motive is to make savings, then you’ll should expect to purchase some electricity from the grid during the year.
• Electricity usage. The average household uses about 16kWh of electricity on a daily basis. During the daylight hours, most of these household will use a third of their electricity when the solar panels are still generating electricity, while the remaining two third are purchased from the grid. In other words, you’ll require a minimum of 10kWh battery capacity if you were to use a battery to power the electricity you purchase from the grid.

For a typical British household, you’ll most likely need a 5kWh solar power system which normally generates about 17 to 21 kWh on a daily basis depending on your location in the UK.

If you’re thinking of adding a solar battery to your home, you might be wondering whether or not it’s going to work in a power cut. If yes, then you’re not alone as this is one of the most common questions asked when it comes to solar batteries. In this post, we aim to provide you with a detailed answer to solve this concern once and for all.

The answer to this question is, it depends. The main reason why your solar batteries will usually not work or provide your home with the much-needed back up power is as a result of the several threats it poses. You should be aware that both your solar panels and battery are connected to the main grid. When a power cut occurs, your engineers will have to operate on the grid. If the solar panels or batteries are in operation at the period there’s a high chance the engineers would be electrocuted by the electricity that’s being produced. As a result of this, solar inverters are usually designed to automatically switch off once a power cut occurs. However, it should also be noted that if your solar battery possesses backup functionality, you’ll be able to make use of your solar energy in the event of a power cut. In other words, what determines if your home battery would work in a power cut is the availability or otherwise of a backup functionality.

Furthermore, you might also wish to know if your solar panels will continue to charge the battery in a power cut. Well, this depends on the type of backup system you possess. There are some more affordable batteries that are designed to automatically release their stored energy upon the detection of a power cut. And this is mostly because the battery inverter is usually smaller than the solar inverter which allows the energy from the solar inverter to the transmitted to the battery - risking an overload. However, if otherwise, then energy can continue to be transmitted to the battery until its fully charged.

With age and use any electrical installation in your home will wear. A periodic inspection is therefore carried out to ensure your home electrics are in a satisfactory condition. With a periodic inspection: Ensure your electrical circuits aren’t overloaded, Avoid accidents such as shocks and fire hazards, Discover if there are any defective lines,Highlight any lack of earthing or bonding..

Registered Electricians will certainly work in uniformity with the UK nationwide criterion, BS 7671 - Demands for Electrical Installations. They will certainly provide a safety and security certification for their electric work to verify that the setup has actually been created, built, evaluated and evaluated, based on the standard.

You should guarantee that your selected Electrical installer is signed up with one of the adhering to companies:

• BRE Certification Ltd
• British Standards Institution.
• ELECSA Ltd
• NAPIT Registration Ltd
• NICEIC Group Ltd
• SELECT (Scotland)
• STROMA
