Find a Solar Panel Installer you can trust in Plymouth.

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.

In a similar way to other major home improvement projects, some specific requirements must be met to allow for the installation of solar panels. The main reason why these standards and regulations were established is to minimize the risk of the solar system becoming an issue or potential hazard in the unforeseeable future. So if you’re thinking about buying and fitting new solar panels, you’ll probably want to know whether or not you’ll require to submit a planning permission application for approval before you can proceed.

Generally, solar panels are covered under what’s called “Permitted Development” which gives you the freedom to install your solar panels without having to apply for a planning permission. However, there are some exceptions to this rule. These exceptions include if your house is a listed building or if your house is located within a conservation area. In these exceptional cases, it’s possible that you’ll need to apply for a planning permission, but this will largely depend on the discretion of your Local Planning Authority. What’s more? Solar panels are usually subjected to normal building regulations which includes examining the roof to make sure that it can support the additional weight. You can call in a MCS certified installer to carry out this check for you.

In order to install your solar PV on your roof, you must follow these guidelines:

✓ Your solar panels shouldn’t go beyond the highest point of the roof (excluding chimneys).

✓ The solar panels shouldn’t project beyond 200mm off the roof’s edge.

✓ The solar panels should be removed once they’re no longer used to produce electricity

✓ The solar panels should be installed such that the area and building’s appearance change is minimized.

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.

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.

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.

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.

One of the things that has been on the UK government’s agenda for some time now is to promote the use of renewable energy sources. In fact, the Renewable Energy Directive put out by the EU instructs all member countries to achieve a 20 percent renewable target before the year 2020. The UK’s commitment to this objective has been made quite glaring with a number of funding options that has been put in place to help business owners looking to solar panels on their properties. This commitment was also showcased by a reduction in the cost of solar panels, so new investors have little to worry about. Although there aren’t any grants in the conventional sense, but there are opportunities for solar panel funding in the UK. At present, the only scheme open to new applications is the SEG - Smart Export Guarantee which came into effect on 1st January, 2020.

In general, there are four notable incentives in the UK for solar panels which includes the aforementioned Smart Export Guarantee, Reduced VAT on Energy Saving Products, Feed-in Tariff ( no longer open to new applications ), as well as the Renewable Heat Incentive ( RHI - applies only to solar water heating ).

Being the only one still open to new applications, we’ll provide you with some insights on SEG. The Smart Export Guarantee allows small scale low-carbon electricity generators to receive payments for surplus energy they’re able to export back to the grid. Although, this is not a direct government scheme, all licensed suppliers are necessitated to offer an export tariff to their customers. Those suppliers with more than 150,000 customers are obligated to offer a tariff, while the suppliers with fewer customers can partake on a voluntary basis.

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.
