Find a Solar Panel Installer you can trust near you.

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.

Most people want to connect solar panels to a battery when they’re not at home all day to use the electricity they generate, or generate more than they consume over a day. Solar batteries are a great way to maximise the savings on your energy bills since you can use every unit of electricity you generate.

If you want to connect your solar panels to a battery, the best – and safest – way is to ask an MCS-registered company to do it for you. They’ve had lots of training and hold qualifications in handling electricity and installing solar batteries, so they will be able to recommend the best battery for your solar panels and for the among of electricity you use. Some of the brands they might recommend include Tesla, SolarEdge and SolaX, but there are many more to choose from. If you want to send electricity to the grid from your battery to receive Smart Export Guarantee (SEG) payments, it’s also worth leaving installation up to a registered installer. This is because you might not be eligible for payments if your battery wasn’t installed by an MCS-registered company.

However, if you do want to have a go at connecting your solar panels to a battery, it’s worth finding out whether your system is ‘storage ready’. Most relatively new systems will be, since batteries are becoming more commonplace. If your solar panels are storage ready, they will have an inverter that can easily have a battery added to it. If this is the case, then you should be able to buy the solar battery you want and follow the manufacturer's instructions to install it.

But it’s worth remembering that electricity is extremely dangerous when handled improperly. If you don’t get the solar battery connected properly and something goes wrong, it could cause a fire or you could electrocute yourself. If a fire breaks out due to your battery, it’s unlikely that your home insurance company would pay out since you connected the battery yourself. That’s why it’s always worth speaking to a registered installer to install a solar battery storage system for you.

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.

If you want to test your solar panel system to see if it’s working properly or just to see what output it’s giving, you can do this using a multimeter to measure current, or amps, and voltage.

Before you start, you’ll need to find the voltage (v) and current (A) ratings of your panel. You should be able to find them on the back of the panel. You should also make sure that it’s a nice clear, sunny day to get the best readings out of your panel. You should also check that it’s safe to be up on your roof!

To measure open circuit voltage, you’ll need to make sure that your solar panel is completely disconnected from your system’s regulator and battery (if you have one). Angle the panel towards the sun, and ensure that your multimeter is set to measure volts. Measure the voltage between the positive and negative terminals by connecting the negative contact on the voltmeter to the negative on the panel and the positive contact on the voltmeter to the positive on the panel.

Then, you can move on to the short circuit current. Follow the same steps as the open circuit voltage, but ensure that your multimeter is set at 10A to start with.

Only try to test your solar panel if it’s safe to do so. If your roof isn’t accessible without scaffolding or specialist equipment, consider speaking to an MCS-registered solar company about your concerns. They may recommend that they come to service your solar panel system.

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.

There are a few trusted companies in the UK that make solar panels. While there are other solar thermal panels out there that are made by Chinese and American companies, we’ll focus on the brands with a longstanding presence in the UK since these are the panels MCS-registered solar companies are likely to recommend to you.

Viessmann, Worcester Bosch, Solar UK and Dimplex make some of the best solar thermal panels in the UK. Dimplex and Viessmann offer both flat plate and evacuated tube solar panels, while Solar UK only offers evacuated tubes. Worcester Bosch’s Greenskies range are all flat plate collectors. Viessmann’s panels come with a 5-year warranty, while Worcester Bosch and Dimplex offer extensive 10-year warranties. However, Solar UK offer a comprehensive 25-year warranty and guarantee that the panels will deliver the same level of performance for 25 years!

We’d recommend choosing evacuated tube solar thermal panels because they are the most efficient. While there won’t be much difference between evacuated tubes and flat plates in the summer, in the winter evacuated tubes are much better at taking heat from the sun than flat plates. Since our winters are long and cold with few daylight hours, we think it makes sense to go with evacuated tubes. However, if your priority is looks over maximising efficiency, you might want to choose flat plate collectors since they sit flat on the roof and look more like solar PV panels, whereas the evacuated tubes will stick out.
