Find a Solar Panel Installer you can trust in Swansea.

If you’re thinking about installing a solar thermal system in your house, it’s always important to put into consideration numerous factors before you proceed. While some solar thermal systems are suitable for use at home, there are also some that are suitable for businesses or organizations which normally requires a big amount of hot water like hotels, restaurants, schools, hospitals and many more. You’ll also find some types available in the market that are suitable for communities to satisfy communal hot water demands.

It should, however, be noted that solar thermal systems do not have the capacity to produce all the hot water demand of a house. In the UK, an average household will need an annual water heating of between 3000kWh to 5000kWh. Whereas, a solar thermal system is only able to meet about 40 percent to 60 percent of this demand.

With that in mind, it’s also worth noting that during the summer months when the solar radiation is at its peak and hot water demand is relatively lower when compared to other seasons, a solar thermal system may be able to provide all of your household’s hot water needs. This implies that during this period you may not find the need to operate your boiler at all. However, during winter or colder months, when you have a higher hot water demands in contrary to a lower solar radiation, a solar thermal system will only be able to take care of about 20 percent of your household’s hot water needs. And that ultimately implies that during this period, you’ll need to rely more on a alternative or backup source of heat like gas, coal, electricity, oil or LPG.

Solar thermal panels are panels that can be used to heat your hot water. The collectors, which are either evacuated tube panels or flat plate collectors, harness heat from the sun and transfer it to a heat transfer liquid that heats up water that is stored in a hot water cylinder. You can use a boiler or immersion heater as a back-up in the winter or to heat the water up further to reach the right temperature.

Evacuated tube panels involve a bank of glass tubes mounted on the roof tiles, and while they’re usually more expensive, they’re more efficient than flat plate collectors. They’re exactly what they sound like – flat panels that can be fixed onto your roof tiles or integrated into the roof.

Having a solar thermal system will reduce your energy bills since heat from the sun is free, so you won’t have to rely on your traditional heating as much. You’ll also be doing your bit for the environment – if you have a natural gas heating system, you could save up to 295kg of CO2 every year.

Another benefit to solar thermal panels is that you might be eligible for payments through the Renewable Heat Incentive (RHI), which is a Government scheme to encourage people to take up renewable heating technologies. As long as you have your system installed by an MCS-registered installer and you meet a few other requirements, you could receive payments of up to £525 per year for seven years. And since the average solar thermal panel system costs £5,500, you could pay off over half of your system just with these payments. That’s not even considering that you could save up to £60 a year on your energy bills if you have a gas system.

Solar energy is renewable, as the sunlight it uses won’t run out. This means that it’s a great way to generate electricity without damaging the planet. So, installing solar panels to generate solar energy can be a great move for businesses looking to reduce their carbon emissions.

Yes – solar panels do work in winter. Contrary to popular belief, solar panels can still work under daylight, even if it's not hot. Of course, they won’t generate as much electricity as they would during the summer months, as the days are shorter, but they will still generate electricity during those daylight hours.

Once you know how solar panels work, it’s easy to understand why solar panels work in the winter. Solar panels are made up of photovoltaic (PV) cells, which are units usually made out of silicon. These cells contain electrons that create energy when light hits them. The cell can then convert this energy into usable electric current and into your system to be used around the home.

Although it might seem strange, solar PV cells can actually work better when it’s cold. Too much heat around the cell can cause it to be inefficient, due to the difference in energy between the energy from the sunlight and the electrons in the solar cell. During cold weather, the difference between them is higher, so more

The higher the energy difference between the two sets of energy sources, the more power that the cell can produce when it’s struck by light. Of course, the downside is that there are fewer daylight hours in the winter, so you’ll still see a drop in energy production – but at least you know that your solar panels are still working efficiently. The other thing to bear in mind is that obstructions like snow and lots of cloud cover will impact the amount of electricity your solar panels will produce. Luckily the UK doesn’t get too much heavy snow, so any snow that does settle on the panels will melt quickly. As for cloud cover, even on exceptionally cloudy days your panels will still generate some electricity – just not as much as they would on a clear day.

Yes – solar thermal can be used for central heating. Solar thermal panels work by collecting heat from the sun, either through evacuated tubes or flat plate collectors, and transferring that to a heat transfer liquid that heats your hot water. This can then be used to preheat your central heating.

You’ll need a hot water cylinder to store the water that your solar thermal panels heat up. It’s likely that you’ll need an immersion heater or boiler to heat the water further so you can use it for your central heating, and as a back-up during the longest winter months since the solar panels won’t be able to generate as much heat.

In our opinion, it’s best to use your solar thermal panels for hot water rather than your central heating. That’s because you use hot water all year round, whereas you probably won’t have your central heating on in the spring and summer, when the panels can generate the most heat. For central heating, air- or ground-source heat pumps are a great renewable option, and you can even power them with electricity from solar PV panels if you want to be as eco-friendly as possible.

How Do Solar Panels And Batteries Work Together?

With solar panel system rapidly becoming an ubiquitous phenomenon within the modern society, several homeowners in the UK are just coming to terms with the numerous benefits offered by the system. The solar power’s popularity has even led to the rise of another renewable technology - solar batteries able to store excess solar power that can be used later. Now several companies such as Tesla are now building solar batteries that can be fitted alongside solar panels for your building. So how exactly do solar panels and batteries work together? Let’s have a look!

Solar panels make use of the sun light to generate electricity and as a result, they can’t function when sunlight is absent - giving a big issue of how to power your house when it’s dark. In the event whereby this occurs, you’re afforded two options which is either to contact energy providers to buy electricity or purchase a battery storage system.

So what’s the function of the battery storage system? Basically when your solar panel provides electricity which is not needed right away, a solar battery will work to convert the DC electricity into AC energy which is going to be stored for later use (when you actually need it). in other words, your solar panels charge the batteries when you do not require the energy they’re generating right away.

As a result, when it’s dark and the solar panels are no longer functioning, your system will tap into the energy that’s already been stored by your battery for later use. This way, you can be totally independent of the National Grid, which implies more savings on your electricity bills.

The importance of selecting the right size battery for your home simply cannot be overemphasized. A lot of home and property owners are facing this challenge and understandably so. Selecting the right battery size for your needs depend on a number of factors which includes your motive for adding a battery, your electricity usage, your budget as well as your panel array size, be it new or existing. In this post, we’re going to take you through some of these factors to help you determine the right battery size for your home or property. Let’s take a look!

• Your motive for getting a battery. While most people purchase a battery to wipe out their need to purchase electricity from the grid with the hope of making some savings, others add a battery so as to enjoy backup power. There are also some who just needs it to power their home with solar energy. It’ll not be economical to size a battery to effectively take you off the grid, but if your motive is to make savings, then you’ll should expect to purchase some electricity from the grid during the year.
• Electricity usage. The average household uses about 16kWh of electricity on a daily basis. During the daylight hours, most of these household will use a third of their electricity when the solar panels are still generating electricity, while the remaining two third are purchased from the grid. In other words, you’ll require a minimum of 10kWh battery capacity if you were to use a battery to power the electricity you purchase from the grid.

For a typical British household, you’ll most likely need a 5kWh solar power system which normally generates about 17 to 21 kWh on a daily basis depending on your location in the UK.
