Asides from the fact that solar energy can be converted into electricity with the help of solar panels, there’s also another pretty cool way the sun’s power can be harnessed - solar thermal technologies. These technologies are able to convert sunlight into heat rather than power and these are in fact the very first solar energy products that were commercialized in the United Kingdom. Solar thermal panels, in a similar way to solar PVs, can help in minimizing your carbon footprint while also assisting you to save good money on your energy bills by providing the much needed coverage for your heating needs with the help of a renewable energy source that’s totally free.

Solar thermal panels provides some great benefits which is capable of making all homeowners in the UK consider installing one in their respective homes. Let’s take a closer look at these benefits.

✓ When compared to solar PV panels, they’re a more affordable heating option and also have a shorter payback period.

✓ Solar thermal panels are more efficient than PV panels due to the fact that the heat waves are able to hold more energy than sunlight and also because there’s no electricity transformation process.

✓ Solar thermal panels are able to operate in cold climates, strong wind as well as overcast weather, and make use of an energy storage system.

✓ They can help you save about 600kg of carbon dioxide emissions on an annual basis.

✓ Although most of the solar thermal panel systems come with a warranty usually within the range of 5 to 10 years, they’re able to last up to 25 years. What’s more? The require just a little maintenance, meaning the main cost you’d have to worry about is the cost of installation.

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.

Not only will you reduce your electricity bill by generating your own electricity with solar panels, but you can also earn money through the SEG which is offered by large energy suppliers. They’ll pay you for the electricity you export back to the grid. You’ll also reduce your carbon footprint, lessening your impact on the environment.

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.

There are two different types: flat plate, where lots of thin tubes carry water through a flat absorber panel, and evacuated tube, where vacuum glass tubes capture the sun’s energy directly. There is little difference in performance between the two but evacuated tube panels do more obviously extrude from the roof.

If you’re interested in getting a new air source heat pump, then you’d probably want to know if they’re really advantageous, cost effective and efficient. The fact is, there are a plethora of benefits that comes with using heat pumps which is a renewable alternative to warm up your home in the UK.

An air source heat pump can help you save money on energy bills while also minimizing your carbon footprint as compared to a gas or electric heating system. Another important benefit that comes with air source heat pump is the fact that they’re quire versatile and yet affordable. Generally, they can function either for heating or cooling purposes and they can also be incorporated for either heating of space or water. In fact, in order to achieve the target Net Zero by 2050, the UK government are looking to fit 19 million heat pumps in new builds. With significant rise in the deployment of heat pumps, the grants by the UK government enables this renewable energy source to become a lot more affordable to run while also helping to minimize the burden of the air source heat pump cost.

As perfect as it seems, this renewable source of energy also comes with a number of disadvantage which we’re going to list out. Let’s take a look!

• There must be sufficient space outside the house to accommodate the external condenser unit.
• The condenser unit can make a lot of noise and even blow colder air into their immediate area.
• Since they consume electricity to operate, this also means they’re not zero carbon unless the electricity is produced from a renewable source like solar panels etc.

Obviously the performance of a solar thermal system will vary depending on the location of the home, the insulation of the property, and your own hot water requirements. Solar thermal panels are capable of providing all of your hot water requirements from April to September. They will still make a contribution to your hot water needs for the rest of the year, but in general you will need a backup system to further heat the water in the colder months.
