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 thinking about rewiring your three bedroom house, one of the first few things you’d have to put into consideration is the cost of completing the project in order to help you set a budget and start to plan. In this post, we seek to provide you with the most accurate cost possible for your project to help you get started as soon as possible.

In truth, there’s no simple and short answer to this question as the average cost to rewire a house is based on a wide range of factors. For older properties, you may need completely rewire the property in order to enhance the energy efficiency. However, this may not be required the your home was just recently built. Firstly, it should be stated that there are numerous factors that affects the price of a rendering a house which includes the size of the house and its condition, the ease of access, the prep work required, as well as your location and the quality of the contractor your hire. Out of all these factors, the most significant variables are probably the type of rewiring task you go for (whether for the whole house or some specific parts ) as well as the size of the house.

House rewiring is usually a messy and disruptive task which can also be very dangerous especially when handled by a inexperienced individual. As a result, we’d strongly recommend that this task is carried out by a qualified and registered electrician who is well trained to perform this task to perfection. The average cost for electrical rewiring for a three bedroom semi detached house should be within the range of £3000 to £4500, although there may be some extra house rewiring cost that may also arise in the process.

How Many Solar Panels And Batteries Do I Need?

Are you presently considering adding a solar system to your home? With several homeowners in the UK using solar now, many more are realizing the numerous benefits they stand to derive by getting one. Therefore, if you’re thinking about adding the system to your home but do not know where to start, you’ve come to the right place.

Here, we’ll help you calculate the number of solar panels and batteries you’ll need to power your home. Starting from the panels, you can begin by taken into account everything that makes use of power in your home to get a good idea of how many you’ll need.

• Firstly, you’ll have to determine the number of watts you use. Simply go through your utility bill for kilowatt-hours (kWh). This varies amongst homes and being able to identify your daily average energy usage will assist you in getting your solar needs.

• Secondly, you have to determine the peak sunlight hours - having in mind that the solar panels only work when under direct sunlight. Once determined, you can then multiply the figure in hours by your home’s hourly energy usage and divide by your selected solar panel’s wattage.

Generally for a 1500 square foot house, you might need around 15 to 18 solar panels to cover the house’s electricity.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries you’ll need for your house. These factors include your home’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications. Once done, you’ll be able to calculate the number of batteries required by your home.

If you’re planning to get an electric vehicle, the next thing that naturally comes to mind is getting a good charger with it. As a result, this is one of the most common questions asked when it comes to electric vehicles. We’ve put together this list of some great home ev chargers to help you make the best informed decision possible moving forward. Let’s take a look!

• Charge Point Wi-Fi Enabled Level 2 EV Charger. If what you need is a faster charge for your car due to the high frequency of usage of the electric vehicle, then this charger might just be the best option for you. It’s claimed to charge electric vehicle batteries six times faster than a standard 120 volt home system. What’s more? The mobile application will inform you about the amount of charge your battery has regardless of your location. This feature can be of great benefit especially when you’re trying to determine whether to put in an additional hour at work or heat straight home.
• Juice Box Pro 40 Level 2 EV Charger. This is a level 2 charger which features a web based charging control so as to allow you control the charging parts of your vehicle from anywhere, be it in the comfort of your home or office without having to go to the garage or parking lot.
• Siemens VersiCharge VC30GRYU. This is an easy-to-use plug and play installation that comes with a mounting bracket if you happen to own a NEMA 50 receptacle. It boasts a charging time that’s 4 times faster than level 1 electric vehicle chargers and possess a charge delay feature or 2, 4, 6 or 8 hours.

The OLEV Grant, also known as Electric Vehicle Homecharge Scheme (EVHS) can reduce the cost of your home charger by up to £350. If you're eligible, you'll be able to claim it when you buy an EV charger.

Fuse box prices will vary and a periodic inspection should be carried out first. However, domestic fuse boxes cost an average of £460. A qualified electrician will advise if yours needs to be replaced and it's always a good idea to obtain a number of quotes before committing to this.

Unlike the photovoltaic (PV) power which works to turn a part of the electromagnetic radiation of the sun directly to electrons and electricity, a solar thermal can simply be referred to as the absorption of the sun’s heat for human use. As a result, the solar thermal has a wider range of uses than the PV does in several ways. This is due to the fact that the sun’s heat can be absorbed and transported via a medium and the stored energy incorporated for several great purposes such as to heat water, to heat and cool a home or living space, to prepare a meal as well as to generate electricity. All these functions are useful for both residential and commercial spaces.

There are generally three different ranges of solar thermal energy that are being used which includes the low temperature ( for heating, cooling as well as ventilation), the mid temperature ( used for preparing meals, heating hot water and the likes) as well as the high temperature ( used for generating electricity). To focus more on generating electricity, there are a wide array of ways through which the sun’s heat can be directed at creating electricity via a heat exchanger which operates to super heat water or inert gas to power an electricity- generating plant or to produce electricity via a Stirling engine.

In order to increase their output or make them more efficient, evacuated glass tubes are used to encircle the tubes which in turn helps them to collect more heat energy while also protecting them from re-radiating the heat energy absorbed. The trough are normal positioned north to south as well as to keep tabs on the travels of the sun throughout the day.
