6 Myths About Solar Panels

There is no shortage of news on the internet. With the endless supply of information comes a proportionate amount of misinformation as well. It is important to set the record straight and outline the myths surrounding solar panels.

Some of the misconceptions are based on belief and some are based on truth which has been misinterpreted by emphasising unimportant factors.

There are a lot of myths out there about solar panels. Our quick solar panel guide will help you to get to the truth.

Myth 1

Solar Energy Nottingham

Government Grants have stopped

False. The Feed in Tariff payments are still guaranteed for 20 years. These payments mean you get paid for every unit of electricity you generate, plus you get paid for every unit you don’t use and send to the national grid.

Myth 2

Solar panels only work in bright sunshine

False. Solar panels do produce electricity in cloudy weather infact only daylight is required. They don’t produce as much electricity as they do on sunny days, but they have been shown to produce 25% of what they produce on a sunny day, or 10% when it’s very cloudy.The average household electricity consumption is 3300KWh per year, a 4KWp Solar PV System will produce around 3400KWh per year.

Myth 3

Your solar panels have to face south

False. Though south facing roofs will have the most direct sunlight exposure, the negative is that your roof does not have to face south for solar to work. East or west facing panels are slightly less productive, but only by about 15-20%. Factors like the cost of energy and available incentives will affect your solar economics much more than roof orientation.

Myth 4

It takes 20-30 years to get your money back from solar panel

False. Advances in technology and the Feed-in Tariffs have greatly reduced ‘pay back’ time. The average payback term is 5-7 years.

Myth 5

Solar panels lose efficiency quickly

False. Most panels are guaranteed for 25 years to work at 80% of their original efficiency minimum. Solar Modules will continue to work well over 50 years

Myth 6

I need planning permission

False. Since a change in legislation in April 2008, the installation of solar panels has been deemed ‘permitted development’ and therefore planning permission IS NOT required, unless you are living in a conservation area or area of natural beauty. .

What Are the Benefits of Solar Panels in the UK?

What are the main solar energy pros and cons? On the pros side, solar energy can reduce your energy bills, increase your property value, sell back electricity, protect you against rising energy costs, and reduce your carbon emissions. On the cons side, solar energy doesn’t work on every roof, it may not be a smart investment if you’re about to move, it gives lower returns on investment if you have a small electricity bill, up-front costs can be high, and finding the proper installation company can be difficult. Below is a list of the main advantages and disadvantages of this renewable source of energy:  
Advantages Disadvantages
Renewable Energy Weather Dependent
Reduces Energy Bills Uses a Lot of Space
Low Maintenance Costs
Sell Back Electricity
Independent of Grid


Solar improves the value of your home

Millions of UK homeowners are interested in solar panels but haven’t taken the time to figure out what it takes to install them. This consumer reality, and the undeniable benefits of having solar panels on a home, complements recent studies that found property values increase after solar is installed. Infact research shows that energy saving measures boost house prices by up to 14%. The DECC found that energy saving home improvements, such as solar panels, could increase property values by on average £16,000. Even if you’re planning on moving in the near future, you’ll earn back your solar panel investment and then some when you sell your home.

Independence Off The Grid

Solar power provides the great benefit of energy independence. The ‘fuel’ used to produce solar energy cannot be bought or monopolized so it is free for all to use. Once you have the solar panels installed you basically have an independent source of electricity that belongs to you. This must not be looked over and is important for the future not only for you but for companies, cities and countries alike.

Reduces Electricity Bills

Since you will be meeting some of your energy needs with the electricity your solar system has generated, your energy bills will drop. How much you save on your bill will be dependent on the size of the solar system and your electricity or heat usage. Moreover, not only will you be saving on the electricity bill, there is also a possibility to receive payments for the surplus energy that you export back to the grid. if you generate more electricity than you use (considering that your solar panel system is connected to the grid).

Sell Back Electricity

If your system produces more energy than you need, through the generous tariff schemes, you can sell the surplus back to the grid. Thus, apart from cutting down utility bills, your investment in solar panels gives you a warranty for a state-backed income for the next 20 years.

Renewable Energy

Switching to solar energy cuts your carbon footprint, as it is a green, renewable source of energy. Unlike traditional electricity generators, solar power does not release any harmful carbon dioxide (CO2) or other pollutants. Estimates also show that solar panels for homes could save around one tonne of CO2 per year, which comes to approximately 25 tonnes over its lifetime.

Could a water source heat pump work for you?

Water source heat pumps (WSHP) are a highly efficient way of tapping into and harnessing the solar radiation stored in underground sources of water. Solar radiation charges the ground and rock throughout the year, with the water which passes through conducting this radiated heat. Because of the year round radiation and the fact that water is a high conductor of heat energy, the underground water source remains at an almost constant temperature all year round.

The benefits of a water source heat pump

The heat transfer rate from water is higher from the ground, making them more effective than ground source heat pumps. In addition, if using a water source heat pump with a moving body of water, the heat is constantly being replaced, as new warmer water replaces the cooler water that has had its heat extracted by the working fluid. For every 1kW of energy required to run a water source heat pump, 4-5kW of equivalent heat energy is produced which can be used to warm your home. This makes the technology more efficient than both air and ground source heat pumps. The supply of hot water is also pretty much constant, despite being cooler in the winter; the body of water will still possess sufficient heat to enable the water source heat pump to operate in the winter. An issue only arises if the body of water completely freezes. Unlike ground source heat pumps, where bore holes or trenches need to be dug on your plot for the piping, the pipework for a water source heat pump is relatively simple to install; it simply needs to be situated within a body of water, which should have little impact on your plot of land. Water source heat pumps have a higher Coefficient of Performance than ground source and air source heat pumps: so for every unit of electricity used to operate them, they can produce more hot water. There is little visual impact on the property, since all the pipework in the water source heat pump system is submerged within the body of water.

Business Benefits

Water source heat pumps which meet the Government’s efficiency criteria are eligible for the Renewable Heat Incentive (RHI), making their long-term business case more robust. Because RHI pays for only the renewable heat generated, water source heat pumps are a particularly applicable technology, with some projects seeing an estimated return on investment in just 4-5 years. Additionally, water source heat pumps can be the ideal solution for organisations and developments who need to comply with stringent planning conditions. The pumps produce no harmful on-site emissions, making them suitable for densely populated areas.

Environmental Benefits

Well-designed water source heat pump systems are expected to see in excess of 4kW of heat generated for each kW of electricity use, making them one of the most environmentally friendly technologies available and a great option for meeting strict emissions guidelines. In addition to reducing carbon emissions, these systems emit no harmful on-site greenhouse gasses and compliance with the Environmental Agency standards ensures that there are no detrimental effects to the local ecology.
