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 power of your solar panel system – there's no point buying a higher capacity battery if your system will never generate enough electricity to charge it
• How often you think you will need to charge your battery
• Your budget
• Whether you care about having the latest technology and a recognisable brand name

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.

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.

What an electrical safety certificate offers both home and property owners as well as tenants is peace of mind. However, if you’re going to get an electrical certificate, you’d probably want to know just how much it’s going to cost. In this post, we aim to give you an idea of the electrical safety certificate pricing in order to help you make a budget and start planning. Let’s take a look!

Generally, the cost of getting an electrical safety certificate in the UK is usually within the range of £80 to about £150 for a medium sized home. With that in mind, it’s also important to note that the price you’ll have to pay to acquire an electrical safety certificate is based on a number of factors which includes the complexity of the job, the size of your property amongst many others. All home and property owners including landlords should invest in getting an electrical safety certificate. The certificate can only be legally issued by a qualified and certified electrician and it must document that all electrical appliances as well as connectors within a property are totally safe and in a proper working condition. What’s more? More often than not, an electrical safety certificate test will most likely be completed in less than 24 hours.

The Electrical Safety report bring to life an concerns as regards the status of all electrical appliances and circuits. At present, it isn’t a legal requirement for home owners. However for landlords, it is an obligation to acquire an up to date Electrical Safety Certificate.

Are you thinking about installing a solar thermal system in your home? If yes, the you’d most likely be wondering the exact amount the system is going to cost. Well, you’re not alone. This is one of the most common question when it comes to solar thermal systems and we aim to answer that in this article. So let’s get started!

Unfortunately, the cost of a solar thermal system can’t be given in a single, accurate answer as they vary widely. However, when getting a new solar thermal system, you can expect to pay a sum within the range of £3000 to £6000 ( this includes a lowered VAT rate of 5 percent). The figures provided takes into account the installation costs as well as all the parts ( such as control panel, solar collectors, hot water tank and pipes).

To determine the price of your system, the quality and type of the panels matter. For instance, according to the Solar Trade Association, a properly insulated twin coil cylinder system would be priced at around £4500. in the same tone, it’s also possible to get DIY solar thermal kits that includes all the required hardware which will cost within the range of £1500 to £250. This however, may not be eligible for government support. In order to benefit from the RHI, your system must be fitted by a MCS accredited installer.

The varying prices of the solar thermal system’s initial cost is based on the specification of each individual house. For example, in situations where the building is having complicated water system, the plumbing cost is expected to increase which will have a serious impact on the overall cost of the solar thermal power system.

Unlike in houses constructed in the 1960s, where you’d probably need to rewire the entire house unless the wiring is the modern PVCu coated type, majority of houses built in the 1970s would not need to be rewired. Most often than not, what they’ll need is just a consumer unit as well as an earthing upgrade. If you happen to have a consumer unit change, the electrical professional you hire would have to inspect the most parts of the property regardless. With that answered, you may also wish to know just how often a house would need to be rewired.

First and foremost, in order to make sure that your wiring is safe there’s a need to ensure that a periodic inspection is carried out by a fully licensed and qualified electrician every 10 years. Meanwhile for rental properties with tenants, the landlord is required to carry out a periodic inspection at least every 5 years. This will make sure that the electrical works in the property are safe, up to date and suitable for continued usage.

In order to determine whether your house needs to be rewired, there are some signs or indicators you’d have to watch out for. If you notice one or even a combination of the following , then you should get in touch with a registered electrician:

• Discoloured outlets and switches
• Persistent burning smell
• Outlets problems
• Flickering lights
• Tripping circuit breaker or blown fuses
• If you happen to possess aluminium wiring
• If you have continually experienced electrical shocks

It must, however, be said that rewiring a house is a messy and quite disruptive work. It’s also considered to be quite dangerous and recommended to be carried out only by a professional is well trained and experienced when it comes to tackling electrical works.

If you are thinking of buying an electric vehicle, then one of the first things you’d have to put into consideration is charging. When it comes to charging of your electric vehicle, doing it at home is one of the most convenient things that comes with it. Not only do you get to avoid the fuel stations, but you’d also get to drive a car in a much cheaper way. Fitting an EV charger or wallbox at your residential space gives you the option to add miles to your battery in a lot faster manner than making use of a three pin plug. In fact, there are also some chargers that offers a lot more than just being a fast way to charge your vehicle.

So which home ev charger should you use? There are a wide range of options available in the market today, however you can get the perfect match for your vehicle by answering these few questions:

• Can you park two cars side by side? If yes, then a tethered charger might just be your most suitable option. A tethered cable is one that’s always connected to your home’s charger. One of the major benefits of using this is that you can get home and plug the charger straight it without having to fetch the cable or carry it around.
• Is size and design crucial? If yes, then you can consider wallbox chargers or untethered wallboxes which are smaller in size and minimalist in design.
• What if your WiFi isn’t accessible? If your WiFi signal is poor in the spot where the charger is to installed but your mobile phone signal is good, then Ohme is a good option to consider.
