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.

When it comes to the electric vehicles world, one of the most common questions that’s usually asked is - how to charge my electric car? If you’ve carried out some research, you’d would have seen terms like level 1, level 2 or level 3 being thrown around. In this post, we’re going to consider the meaning of an ev fast charger to give you more insight into the electric vehicles world. Let’s take a look!

As the name suggests, fast charger is an electric vehicle charger that’s a lot faster than the average ev charger. These incredibly powerful units can have your vehicle charged to 80 percent within an hour depending on the model and capacity of your car while also being highly convenient for those who are always on the go. So what’s the difference between rapid and fast car chargers?

Generally, fast car chargers are available in two varieties which includes - the 7kW which is the most popular option used in homes, or 22kW which is commonly used in supermarkets as well as shopping centres. While 7kW takes up within 4 - 6 hours to charge an ev battery to 100 percent, 22kW will take about 1 - 2 hours to do the same. Most fast devices will be AC, there are also some DC ones available as well. What’s more? A large majority of fast car chargers are untethered. This implies that the cable isn’t connected to the device allowing you to make use of your own. This can, at times, make it a lot more convenient than rapid chargers which makes use of tethered cables.

Whether solar panel batteries are worth it depends on how much you’re at home and how big your solar panel system is. If you’re at home most of the day and your solar panels only generate enough electricity for you to use while for that day, then a battery probably isn’t worth investing in. However, if you have a large system that generates more than you can use or you’re out most of the day, then solar panel batteries are definitely worth it.

A solar battery storage system works by storing the electricity that your solar panels generated until you need to use it. That’s why they’re great for people that are out all day – your solar panels generate electricity all day whilst the sun’s out, but no one’s home so you’re using minimal energy except for things like your fridge and any appliances on standby. Most of the electricity charges your solar panel battery. Then, when you get home, your battery will discharge, and you’ll use all the solar electricity that your panels generated during the day.

Solar batteries are also excellent for people with large solar panel systems that generate more than they use in the day. Any electricity that you don’t use during the day will charge the battery, so in the evening when the sun goes down, you’ll just use the excess electricity that’s stored in the battery.

To work out whether solar panel batteries are worth it for you, you’ll need to work out how much of your solar electricity you’re using already. If you’re at home and you’re able to run your appliances all while your solar panels are generating electricity, a battery might not be worth it. Also, if you’re receiving export payments from the Feed-in Tariff Scheme (FITs) or the Smart Export Guarantee (SEG), you might want to look at the rate you’re getting paid. If it’s a good rate, it might be more cost-effective to continue exporting unused electricity to the grid. Speak to an MCS-registered installer that will be able to help you work this out.

How Much Does Pat Testing Cost?

When it comes to Portable Appliance Testing (PAT) there’s no particular rule that determines how much such services can cost. However as a rule of thumb, you should take note that when calling in a professional PAT testing company they’re likely to charge within the range of £1 to £3 per appliance that’s going to be tested. However, if you have quite a number of appliances to be tested, then there’s a good chance that the price per appliance can be reduced to serve as a bulk discount. So the more the appliances to be tested, the better.

There are companies that actually offer a pricing that’s below £1 per item, however companies likely are most definitely going to have a fixed minimum number of appliances that are required to be tested or a fixed minimum fee like 60 portable appliances. It must, however, be noted that pricing can also go beyond PAT Testing as several professional companies will add some additional advantages which is more than just the test of each individual appliance. This kind of pricing can include other services such as a thorough visual inspection, plug rewiring as well as fuse replacements. They can also include stuffs like Pail and Fail labels in the pricing.

Generally, the average price of PAT testing will be based on various influencing factors such as the type of the appliance, setting, number of appliance to be tested as well as other related expenses. What’s more? Most PAT companies will offer a company with a PAT Testing Certificate so as to certify that the company is in total compliance and also remains a safe environment to work.

You can find out roughly how old your wiring is by simply looking at it. If the wiring around your fuse box is covered in old-fashioned casing, or is damaged or fraid, it may be over 25 years old and need replacing. This is more common in older properties or houses that have been empty for long periods of time.

What Size Of Electric Boiler Do I Need?

If you’re thinking about installing central heating in your home or property, you’ll be shocked by the plethora of options that’s currently available in the market as regards the boiler type that can be installed. Being a very good alternative to gas boilers or an oil or LPG boiler, electric boilers are here to stay. They usually feature different power outputs which tends to lead to one of the most frequently asked questions about electric heaters - what size of electric boiler do I need? Here, we’ll give you a good insight into sizes of electric boilers available to help you make the right decision.

The importance of getting the perfect size of electric boiler for your home can not be over-emphasized. If your electric boiler size is too small, it won’t be able to provide the level of heat and hot water required. And on the other hand, if it’s too big, it’ll definitely consume more electricity which would be a total waste of money.

To determine the correct size, if you have a wet central heating or water radiators in your home, you’ll need to calculate the boiler’s capacity required to operate them and allow 1.5kw per radiator. To be more accurate, it’s advisable to talk to a professional installer to avoid making a costly mistake. Every professional installer should have an idea of the appropriate size of electric boiler that’ll be needed given your special requirements and home size.

Generally, with a 12k kilowatt boiler, you should be able to operate up to 7 to 8 radiators which is good for smaller properties. For apartments and flats, getting a smaller electric boiler would be the best option.

If you possess an electric vehicle, then you should be well aware of how expensive the cost of getting electric vehicle chargers can be. The portable charger happens to be one of the most costly chargers that’s present in the market today. As a result, many individuals wonder exactly why ev chargers cost so much. After all, its just a little box with some wiring, so why should it cost up to hundreds of pound or a grand plus another grand or thereabouts for installation. In this post, we’ll give you insights to some of the primary reasons why ev chargers are relatively expensive when compared to other charges. Let’s take a look!

• Production factors. The manufacturing and testing phase alone is actually one of the costliest aspects in building a high quality and reliable charger. As stated by one manufacturer, the cost required to make metallic materials to trip switches to the testing phase and the marketing efforts, can all run up to over £30,000. As a result of this high production cost, the average of a new ev charger can be between  £125 to about £300 depending on whether you need a type 1 or type 2 charger as well as the size required.
• Specific design. If you own an ev, you’d know that there’s a standard charging port which allows for easy charging just like in petrol or diesel powered vehicles. The goal is to design a universal charging port whereby all electric vehicles can charge sufficiently.
• Safety. The development of a electrical design involves a lot of engineering which are quite pricey. However, this is a top priority to ensure the safety of both the user and car.

If your fuse box keeps tripping or blowing fuses, it may need replacing. Other signs that your fuse box is not working properly include humming, sparking and lack of power. Contact an electrician and ask for a safety report, this will diagnose the problem and lead to a quick fix.
