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 electrical works, safety is always paramount. Although a complete house rewiring service may seem quite expensive, when compared to the safety it provides, you’d realize it’s well worth it. We know all too well that human nature tends to prevail to overlook small electrical issues until it’s too late or probably gets out of hands. When this happens, not only will you have to spend more to get the issue resolved, but it may also lead to some damages to your property. Hence, the need to identify and resolve electrical deficiencies as soon as possible. In this post, we’ve compiled a shortlist of some of the top signs that your house needs rewiring. Let’s take a look!

• Dimming or flickering lights. This is one of the most common signs that your house needs to be rewired. When a light brightens, it means there’s too much voltage and when it dims, it implies it’s receiving too little voltage. You may be tempted to think this is a lighbulb issue, but this type of decline in power is usually as a result of a loose wiring or faulty circuits which should not be ignored.
• Regularly blown fuses. With the steady development in technology as well as electrical appliances within our houses, older style fuses that are not designed to contain this amount of electricity will end up blowing. If your fuse blows on a more regular basis, then there may be a need to upgrade them to more modern circuit breakers.
• Lightbulbs burning out in their sockets. This is usually a sign of bigger issues in your wiring which is often caused by fluctuations in voltage.
• Sparking outlets. These can be perfectly normal, but at times they can also be a clear signal of a potentially dangerous problem which should not be ignored.

When the wiring on your property becomes dated, dangerous or non functional, then rewiring of your house becomes a necessity. If you’re thinking about rewiring your 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 general, the average cost to rewire a house can vary from £2000 to about £10,000, which includes the prices for both material and labour. Factors that can have a great influence on the final price includes the type of your property, the quality of the existing wiring as well as the complexity of the installation needed. The most important determinants 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. The qualification of the electrician hired and the labour costs will also influence the final budget required to a great extent. Overall, the average cost of rewiring a house stands at £4000 and it will usually take up to 7 days for a complete rewire to be done. 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.

Being a messy and disruptive task which can also be very dangerous especially when handled by a inexperienced individual, we’d strongly recommend that house rewiring is carried out by a qualified and registered electrician who is well trained to perform this task to perfection.

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..

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.

Also commonly referred to as a consumer unit in recent times, a fuse box is responsible for controlling and allocating of the electricity in your home. They hold the power any time there’s an overload in one of the circuits which in turn, prevents fire as well as electrical damage. Fuse boxes are often incorporated in homes but consumer units are very rapidly replacing them. Therefore, when your fuse box breaks down, it’s always a smart decision to replace them with consumer units due to the fact that they’re safer and also comply with building regulations while also being a lot easier to use. If you’re extending your home, upgrading to a larger capacity model enables you to make use of more power with the power overloading. In this post, we’re going to cover the amount you’re expected to pay to replace or install a new fuse box or consumer unit as well as the factors that may affect the cost.

For a 10 way dual RCD consumer unit, the typical cost range will be between £250 to £600, meanwhile 15 way dual RCD consumer unit should cost within the range of £300 to £700. Overall, the smaller the house, the fewer the circuits that’ll be needed, hence the difference in the aforementioned prices.

There a number of factors that can affect the cost of replacing a fuse box. These factors includes the the size of the house in question ( the bigger the house , the more the circuits there are and the bigger the fuse box needed), the location ( for instance, places like London where there are higher demands are likely to be more expensive than other regions ).

Like every other systems in your home, solar hot water systems will require periodic inspections as well as a regular maintenance in order to keep it running as efficiently as it should. Not only that, the various components will also require either repair or replacement from time to time. It’ll also be proactive to take the necessary precautions so as to prevent worrying issues like corrosion, scaling or freezing.

Is it a task you can handle on your own? Well, there are some inspections and maintenance activities you should be able to handle on your own, however, you’ll also require a qualified technician to carry out the more technical or complicated tasks. You should also take note that it may actually be more cost effective to have some systems replaced, shut off or removed completely than having it repaired. Here are some of the essential inspections that should be carried out on solar system components. They include:

✓ Collector soiling. Periodic cleaning of your collectors is important especially in dry and dusty climates.

✓ Plumbing, ductwork and wire connections. Check the pipe connections for fluid leaks. Examine duct connections and seals. Also make sure that all wire connections are tight.

✓ Roof penetrations. Flashing and sealant around the roof penetration should be checked to see that it’s in a good shape.

✓ Collector shading. Check for shading of the collectors on annual basis as this may greatly affect their performance.

✓ Support structures. Examine all bolts and nuts which connects the support structures to the collectors for tightness.

✓ Heat transfer fluids. Anti freeze solutions in liquid solar heating collectors will have to be replaced periodically. And this right here is a task that’s best handled by a licensed technician.
