Solar Panel Installer FAQs

How do I test my solar panel?

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.

how much does a solar thermal system cost?

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.

How do you find an installer for commercial solar panels?

Commercial solar panels installation companies are everywhere. However, it’ll be a great mistake to think finding one nearby for your project would be the least of your worries, as both cost and reliability comes into question. This is even more worrisome when you’re fully aware that your solar system potentials can only be fully maximized depending on how well it’s installed and how good your installer is. If you’re also facing the same challenge, then you’ve come to the right place. In this article, we’ll share with you some tips on how to choose a nearby professional and reliable commercial solar panel installer who’ll ensure you get immense value for every penny spent. Let’s take a look!

  • Ask for recommendations. Personal recommendations is always the best way to go, when looking for a commercial solar panel installer or any other tradesperson for that matter. Installation of a commercial solar system is a major undertaking which comes with a lot of costs, so if you’re going to do it the least you can do is ensure you do it right. Carry out your research, ask friends and family, neighbours and loved ones if the know of any reliable commercial solar panel installer in the local area. If they have one they’ve used, you can request for the cost, quality of the job done, the duration of the project and any other detail you feel you should know.
  • Internet. In modern times, you’ll hardly find a progressive-minded business without an online presence. As a result, finding a service on the internet is as simple as it gets. A simple Google search have been helping people find their desired service providers with relative ease for so long. Or use the Quotatis directory to find a commercial solar installer. To get the right commercial solar panel installer online, it’s advisable to check their reviews as well as testimonials before moving forward.
How to install solar thermal panels?
We always recommend that you ask an MCS-registered company to install your solar thermal panels so you can take advantage of the RHI and any other schemes that may come up in the future. However, if you’re sure you want to do it yourself or you just want a rundown of what the installers will do, here are the general steps on how to install solar thermal panels:
  1. After the installer’s measured up, given you an estimated output and recommended some systems for you, they’ll arrange date to come to your home to install the solar thermal panels. They’ll also let you know if any scaffolding will be required.
  2. Next, they will start to fit the panels, or collectors, to your roof. Stainless steel brackets will be provided with the system and they will remove your roof tiles or slates to attach the brackets to the rafters. They’ll then replace the tiles and add waterproof flashing to ensure you don’t get any roof leaks, and add the frame.
  3. If you’ve chosen evacuated tube solar thermal panels, the installer will bolt the heat transfer unit to the top of the frame but not install the tubes until nearer the end. This is because the tubes start to transfer heat to the exchanger immediately, and when everything is unconnected this could damage the unit.
  4. If you don’t need a new boiler with your installation, a new dual coil water cylinder, pump and system control system will be fitted. It’s best in a loft or upper floor of your home.
  5. A new thermal store or hot water tank that will store the heat provided by the solar system is much larger than a standard tank but it may fit in the spot of your old one. The installer will ensure that it’s connected to the mains cold water, your other heating source (such as a gas boiler or biomass boiler), immersion heater, temperature sensors and the solar collectors themselves.
  6. Next they will install the pumping station, usually near the water tank. The expansion tank will be installed on the solar thermal loop, which is usually nearby. Its job is to prevent pressure changes that could damage the system.
  7. You’ll get a heat generation meter which must be MCS-certified if you want to take advantage of the RHI, and any control equipment that comes with the system will be installed.
  8. The installers will then bring the system to pressure by pumping the heat transfer liquid into the system up to a pressure of around 2 bar.
  9. Finally, your MCS-registered installer will register your solar thermal system so you can apply for RHI payments of up to £525 per year.
  10. So that’s the process of installing solar thermal panels. Remember – it's always best to use a professional to install any kind of renewable technology.
Can I buy solar panels?
Yes, you can buy solar panels without having to have them installed by the same company. There are lots of online companies that will sell you single solar panel modules, but there are also lots of businesses that offer DIY solar panel kits with everything that you need to install solar panels yourself. If you’re looking to buy solar panels without installation, you should expect to spend around £4,000-5000 on a 3.5kW system, which is the average system installed in the UK. When you buy solar panels to install yourself, it’s worth bearing in mind that you won’t be eligible for Smart Export Guarantee (SEG) payments. To receive SEG payments, your solar panels need to be installed by an MCS-registered installer, and if any schemes come about in the future it’s likely that the rules will be the same. It’s also worth doing some sums before you decide to buy solar panels and install them yourself. An average solar panel system installed by an MCS-registered company will cost between £4,500-6,000. While that’s more expensive than a DIY solar panel kit, you can claim SEG payments. According to the Energy Saving Trust, you can make your money back on your solar panels within 16 years with the SEG, but without the SEG it could be up to 20 years – and that’s only if you’re at home all day to use the electricity. So before you go ahead and buy solar panels to install yourself, consider whether it would be better to get in touch with some solar companies to get quotes and see if it’s better to pay more upfront.
How do solar thermal panels work?

Solar thermal panels work by capturing heat directly from the sun and using it to heat water. This hot water is then passed through a coil to heat the water for your central heating system. Solar thermal systems are compatible with many existing conventional boilers with hot water tanks, and can be set up to feed in to your existing heating system.

How long do home solar batteries last?
How long home solar batteries last depends on the type of battery you have and how often it’s charged and discharged (when electricity is fed into it, then used later on). Generally speaking, a home solar battery should last between 5 and 15 years. Lithium-ion batteries last longer than lead acid batteries. Lithium-ion batteries are more common these days because they’re more cost effective. A lead acid battery is the cheaper option at around £2,000, but it’s likely to last between 5-8 years. On the other hand, a lithium-ion battery may set you back around £4,000, but will last between 11-15 years. So you can see that it’s well worth choosing a lithium-ion home solar battery. It’s also worth considering that a solar battery’s lifespan will be reduced if you over-discharge it. When your home solar battery is installed, you’ll be left a manual which will tell you its depth of discharge, or DoD. This means how much you can use the battery before recharging it – it's not as simple as letting the battery run down to 0% then charging it again. In fact, this can significantly shorten your battery’s lifespan. If your solar battery system’s DoD is 80% and its capacity is 5kW, make sure you charge it before you use up 4kW to help prolong its life. Luckily, most lithium-ion batteries have a DoD of 80% or more, so you don’t need to worry about not being able to use much of the electricity stored in your home solar battery. This is another reason to use them over lead acid batteries, because their DoD can be as low as 50%.
Can I install solar thermal panels myself?
In theory, you can install solar thermal panels yourself. But it’s best to leave it to professionals. We’ll explain why here. Solar thermal panels work in a similar way to solar PV panels. They use collectors, in the form of evacuated tubes or flat plate collectors, to collect heat from the sun and use it to heat up water that’s stored in a hot water cylinder. You can use a boiler or immersion heater as a back-up to heat the water further so it’s at the temperature you want. So should you install a solar thermal system yourself? It certainly seems tempting since you can buy full solar thermal DIY kits with everything you need for £1,500 to £2,000. To have a solar hot water system installed by a professional, you’re looking at between £5,000 and £6,000, so it looks like there’s a significant saving to be made. However, if you want to take advantage of the Renewable Heat Incentive (RHI) payments, which is a Government scheme where you’re paid for using a renewable energy source to heat your home and/or its hot water, you can’t install it yourself. You need to engage a Microgeneration Certification Scheme-registered installer who can issue you with a certificate to say that the solar thermal panels have been installed correctly. For a 4m2 system that serves a 4-person household, the payments could be up to £375 per year. That means you could pay your system off within 14 years, and that’s not taking into account any of the savings you’ll make on your energy bills. So, while you can install solar thermal panels yourself, it’s much better in the long term to have them installed by an MCS-registered company.
