FAQs

Is it best to get solar panels installed by a professional?
Yes. It will always be best to get solar panels installed by a professional because they have gone through lots of training and have all the relevant qualifications to install solar panels correctly. Whenever you’re dealing with electricity, if something goes wrong it could cause a fire or you could electrocute yourself, so it’s always worth leaving it to the professionals. The other thing to bear in mind is that it’s best to get solar panels installed by a professional, MCS-registered engineer so you’re eligible for Smart Export Guarantee (SEG) payments. The SEG is a government-backed scheme where your energy supplier pays you for each unit of electricity you send back to the grid. Each supplier can set their own rate, but it must be above zero at all times, even if wholesale electricity prices dip below zero. According to the Energy Saving Trust, if you’re at home all day and live in the South East, combine the savings on your electricity bills with your SEG payments and you could save up to £330 a year, meaning the system could pay for itself within 16 years. If you don’t use an MCS-registered company to install your solar panels, you won’t be able to claim the SEG. It’s also unlikely that you’d be able to claim payments for any other schemes that may become available in the future, so it’s always best to leave your solar panel installation to the professionals.
Can I fit solar panels myself?

In theory, you can fit solar panels yourself. In practice, it’s worth leaving it up to the professionals.

If you get DIY solar panels and install them on your roof yourself, you won’t be able to apply for the government-backed Smart Export Guarantee (SEG). The SEG pays you for every unit of electricity you generate and send back to the grid, so it’s a scheme well worth signing up for. However, you must have your solar panels installed by a Microgeneration Certification Scheme (MCS)-registered engineer or company, so you’ll miss out if you install the solar panels by yourself.

The other thing to consider about installing solar panels yourself is that you’re dealing with electricity. Electricity is extremely dangerous if handled incorrectly, so if you don’t have any qualifications in working with electricity you could be putting yourself and your family at risk. Connecting DIY solar panels yourself and doing it incorrectly could mean that you give yourself an electric shock or cause a fire. If your home is damaged due to a fire caused by solar panels you’ve installed yourself, it’s unlikely that your home insurance company would pay out.

Before having a go at installing your own solar panels, do some quick sums to see how much money it could really save you. A 3.5kW DIY solar panel kit will cost around £4,000-5,000. According to the Energy Saving Trust, a home in the South East of England where most occupants are out all day until 6pm would save around £100 a year on their electricity bills. That means that you wouldn’t break even until 40 years, but solar panels last around 25 years on average. However, if you have your solar panels installed by an MCS-registered installer and they cost £4,500, you could save £220 a year including your SEG payments. That brings the payback time to around 20 years.

So although the initial outlay is slightly less when you install solar panels yourself, it’s much better to have them installed by an MCS-registered engineer so you can take advantage of the SEG payments.

Do solar panels work in winter?

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.

Can solar panels cause fires?
It’s only likely that solar panels will cause fires if they are installed incorrectly. The safest thing to do is ask an MCS-registered engineer to install your panels as they have all the relevant qualifications and training in handling electricity. If you choose a reputable company that can prove they have the right certifications, it’s highly unlikely that your solar panels will cause a fire. It’s important to remember that solar PV panels can’t start a fire themselves. It’s other parts that could become faulty that would then lead to a fire. For example, if the connectors in the system aren’t seamed properly, it could cause arcing and overheating, which could then cause the panels to set alight. Another possibility is that the junction box overheats and starts a fire. The junction box is found on the rear side of the solar panel and enables the electrical connection via a connector. Of course, since solar panels harness electricity, there is always a small fire risk – just like there is with any electrical appliance in your home. But there are some precautions you can take to reduce your risk of fire from solar panels:
  • Don’t buy cheap solar panels – while it might seem tempting, make sure you choose MCS-certified solar panels. Any reputable installer will recommend high quality solar panels, which is another reason to have them professionally installed rather than doing it yourself.
  • Ensure that your installer uses non-combustible mounting systems and frames.
  • Check your system regularly for signs of pests gnawing through cables.
  • Keep your solar panel system regularly maintained with proper testing and servicing carried out as recommended by your installer.
  • If something doesn’t look right to you, get in touch with your installer and ask – they should be more than happy to help.
