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.

If you’re looking to install a solar thermal system in your home, this is usually one of the first concerns several homeowners have. Being fully aware that solar water heating systems are usually more expensive than their counterparts - the conventional water heating systems, the question arises whether or not you’ll be able to save some money from your solar water heating system in the long run. In this article, we aim provide an answer to this important question. Let’s take a closer look!

When it comes to solar thermal systems, the money you’ll be able to save in the long run depends on a wide range of factors. These factor includes:

✓ Your system’s performance.

✓ Your geographical location and solar resource

✓ Your household’s hot water demand

✓ Financing and incentive options that are available.

✓ The cost of fuel that’s being used for your alternative or backup water heating system, if you own one.

✓ The cost of conventional fuels such as oil, electricity or natural gas.

There are several benefits, however, that comes with the installation of a solar water heating system. Since the sun is absolutely free, future fuel shortages and price hikes will have little impact on you. Also, on the average if you decide to fit a solar thermal system your water heating bills is expected to drop about 50 percent to 80 percent. What’s more? The economics are even a lot more attractive when you’re just about to build a new home or refinancing. When you include the price of a solar water system in a 30 year mortgage, it’ll normally amount to very low price per month. Therefore, on a monthly basis you’ll be saving more and paying less.

The short and simple answer to this question is, no. If you’re a seasoned DIYer then you should probably know a thing or two about electrical works around your property. However, house rewiring works should only be carried out by a qualified and registered electrician for a handful of reasons. In this FAQ, we’re going to take an in depth look at a few reasons why a house rewiring project should always be tackled by a reliable professional.

• Risk. Not only do you out your own health and that of your loved ones at risk when you attempt to complete electrical rewires on your own, but you also put your property at risk. Tackling electrical works involves a great danger. These dangers can come in different forms such as electrical wires electrocution, shock as well as fire. What’s more? Items in your home also possesses higher voltages, and when it comes to electrical wiring, the higher the voltage, the more dangerous the project becomes. Another tricky task to get around is hidden junction boxes as well as connections. Since these components are out of sight, the chances of you getting shocked increases rapidly. All these risks can only be mitigated when proper procedures are followed . therefore, if you decide to do electrical work on your home, then there’s the need to obtain necessary permits for completing the work. Once completed, the work done should be inspected by a licensed electrical inspector. However, the best way to reduce the risks is by hiring the services of a licensed electrician.
• Safety. Electricians are trained to perfect their craft and comply with safety protocols. They’re also required to pass a licensing test so as to work as an electrician. The safety of your property and loved ones when it comes to your home’s electrical works can only be guaranteed when done by a qualified and registered electrician.

If you’re considering getting a solar thermal system, one of the first things that comes to mind is the possibility of the system functioning properly during the cold months. The short and simple answer to this question is yes, a solar thermal system works in the winter. However, the downside here is that it’ll be a lot less efficient when compared to how it operates during the warmer months or summer. As a result of this fact, you’ll likely need to rely more on your boiler, immersion heater or any other backup heating system during this period as your solar thermal system will fail to contribute as much as it does during the warmer months. So what exactly is the reason why solar thermal is less effective and less efficient in the winter period? Let’s have a look!

As you know, solar thermal system banks on the sun’s energy to heat the water for your home’s use. During the cold months or winter, the sunlight becomes a lot less available when compared to the warmer months, as a result, there’s less sunlight that’s available to be used for its solar energy. And even more so at the periods when the days are shorter or skies are clearly overcast.

Also having a great impact on a solar thermal system’s output is heavy snow. Flat plate collectors normally have the capacity to cope better during snowy conditions as the light that’s able to travel through the snow will heat up the absorber plate - thereby making the snow slide off more quickly. However, the case is contrary with evacuated tube collectors which possesses a form of vacuum insulation that’s crafted to minimize the loss of heat, meaning they can’t generate heat to melt and cause the snow to slide off in a similar way.

Most people want to connect solar panels to a battery when they’re not at home all day to use the electricity they generate, or generate more than they consume over a day. Solar batteries are a great way to maximise the savings on your energy bills since you can use every unit of electricity you generate.

If you want to connect your solar panels to a battery, the best – and safest – way is to ask an MCS-registered company to do it for you. They’ve had lots of training and hold qualifications in handling electricity and installing solar batteries, so they will be able to recommend the best battery for your solar panels and for the among of electricity you use. Some of the brands they might recommend include Tesla, SolarEdge and SolaX, but there are many more to choose from. If you want to send electricity to the grid from your battery to receive Smart Export Guarantee (SEG) payments, it’s also worth leaving installation up to a registered installer. This is because you might not be eligible for payments if your battery wasn’t installed by an MCS-registered company.

However, if you do want to have a go at connecting your solar panels to a battery, it’s worth finding out whether your system is ‘storage ready’. Most relatively new systems will be, since batteries are becoming more commonplace. If your solar panels are storage ready, they will have an inverter that can easily have a battery added to it. If this is the case, then you should be able to buy the solar battery you want and follow the manufacturer's instructions to install it.

But it’s worth remembering that electricity is extremely dangerous when handled improperly. If you don’t get the solar battery connected properly and something goes wrong, it could cause a fire or you could electrocute yourself. If a fire breaks out due to your battery, it’s unlikely that your home insurance company would pay out since you connected the battery yourself. That’s why it’s always worth speaking to a registered installer to install a solar battery storage system for you.

There are a range of variables that will determine which heating system is best for your home, such as the level of insulation and size of rooms. However, electric heating is suitable for many homes. Electric boilers are very compact and do not need a flue. Underfloor heating is effective at heating rooms of any size.

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.

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.
