| Diverse applications |
Without further ado, let's consider the key advantages and disadvantages of solar energy for your home.
Advantages of solar energy
Solar panels have several advantages in the UK, including:
- Saving money on energy bills
A solar panel should reduce your energy bills unless you pull an all-nighter with an empty solar energy storage, of course. Your savings will depend on your solar system size and your electricity consumption.
You can actually calculate your potential bill savings using various tools. Most of them require information about your solar panel size, annual output, battery warranty, cost of battery storage, hourly electricity price and electricity export percentage.
- Reduced carbon emissions
Solar panels are environmentally friendly and can help reduce carbon emissions by producing clean energy. The average residential solar PV (photovoltaics) system in the UK saves between 1.3 and 1.6 tonnes of carbon dioxide from entering the atmosphere each year.
By harnessing the power of the sun, they help us rely less on fossil fuels, which means we can say goodbye to those pesky greenhouse gas emissions that contribute to climate change.
Moreover, solar panels play a crucial role in curbing deforestation, as they provide a clean and renewable alternative to energy sources that require cutting down trees.
- Low maintenance costs
Once installed, they can operate for many years with little to no maintenance. Unlike heat pumps, wear-and-tear hiccups don't happen with solar panels as there are no moving parts.
The only part that requires regular changes is the solar panel inverter which you need to replace every 5-10 years.
So, for proper maintenance, you need to clean your panels a few times a year, whether by yourself or through a cleaning company. Moreover, most solar panel manufacturers provide a lengthy warranty which can reach up to 25 years.
- Renewable energy
Solar panels generate renewable energy that is sustainable and inexhaustible. They can be used to generate electricity anywhere, as long as there is sunlight.
While we can run out of energy stored in panels due to bad weather conditions, we can't run out of sun. Moreover, in winter solar panels also have the remarkable ability to continue generating electricity even when covered by snow. Additionally, during cold and clear days, the snow on the ground can act as a mirror, reflecting additional sunlight onto the panels.
This means as long as your weather and climate allow you to collect energy, you can account for regular electricity production.
- Return on investment
What are the advantages of solar energy for your wallet apart from reduced bills? Solar power can get you a few pennies back through the SEG (Smart Export Guarantee) initiative*. By registering in this scheme, you can earn money for your extra electricity returning back to the National Grid.
Find an SEG licensee near you and check if you're eligible for the SEG. Next, your SEG licensee will offer you a tariff plan which will determine your rate, contract duration, and payment schedule.
*only available in England, Scotland, and Wales.
- Diverse applications
Solar panels can be used to produce heat or electricity for homes as well as for charging home appliances and even electric cars with free energy. To do that, you'll need to connect your solar panels to an inverter which converts the solar DC (Direct Current) energy into AC (Alternating Current) energy. Next, install and connect an EV (Electric Vehicle) charging station to the inverter and your electric car.

Disadvantages of solar energy
Let's look at the core disadvantages of solar energy which separate the sunny stories from the bitter truths. These are a few drawbacks associated with solar panels:
- Dependence on weather conditions
Solar panels rely on sunlight for generating electricity, so their effectiveness diminishes during cloudy or rainy weather. Moreover, it should be noted that solar energy can't be accumulated during the night.
Electricity usage is measured in kilowatt-hours (kWh). On average, the UK gets four hours of sunlight per day, so each square metre of solar panels can generate between 0.6kWh and 0.8kWh of energy. This means that if you have a 4kW solar system, it can produce around 2.4kWh to 3.2kWh of energy every day.
So, let’s say you have a solar system with a total capacity of 4kW. With an average of 4.9 hours of sunlight per day, you can expect to receive about 19.6kWh of power each day from your solar panels.
However, it’s important to keep in mind that the actual power output may vary depending on the specific provider.
The amount of power you need to generate depends on where you’re installing your solar panels and how much electricity you use. A typical British home consumes approximately 3,800kWh of electricity per year, which is roughly equivalent to a little over 10kWh per day.
This is a notable disadvantage for areas in the UK where the number of sunlight hours is lower than 4. This fact can lower the efficiency of your solar panel.
- High investment costs
Many factors influence the cost of solar panels, posing a significant financial hurdle for some homeowners. However, the prices of solar panels have substantially decreased in recent years, making them more affordable.
Based on the system size you choose, your roof space, and the necessary number of panels, the estimated costs of a solar panel might stretch between £5,000 and £11,000.
- Space requirements
The more electricity you need to produce, the more panels you need. Therefore, sufficient space is necessary for installing solar panels, and most systems are typically mounted on rooftops.
This limitation can be disadvantageous for homeowners with limited roof space or those residing in apartments. Moreover, if your rooftop is in poor condition, it will need to be replaced or renovated before installing solar panels.
- Lengthy payback period
On average, the payback period for a solar panel in the UK stretches between 6 to 10 years. This timespan can fluctuate due to electricity prices, energy consumption, tax credits or net metering programs. Moreover, if your location doesn’t get enough sun, this period might last even longer since you’ll need to use more electricity.
You can cut down your solar panel payback period by receiving payments from the SEG scheme for exporting your excess electricity back to the National grid.
That being said, while there are multiple advantages of solar panels for UK homes, such as reduced energy bills and carbon emissions, it’s important to consider the drawbacks mentioned above, including weather dependency, upfront costs, and space requirements.
Nonetheless, the advantages of solar energy often outweigh the disadvantages, making them a promising option for homeowners seeking to decrease their carbon footprint and save on energy expenses.
Conclusion
UK homeowners have a brilliant opportunity to bask in the sunny side of life by considering the installation of solar panels. Not only do they offer a ray of hope for the environment, but they can also give your finances a much-needed boost.
With the impressive installed capacity of solar energy in the country and the dazzling success of small-scale deployments, it’s clear that solar power is the “bright” choice in the UK.
Solar panels bring a sunny disposition to homeowners, helping them reduce their carbon footprint as well as their electricity bills. It can even turn your roof into a money-making machine by generating excess energy as well as increase your property value if you ever decide to sell your house.
Of course, it’s essential to consider certain circumstances where solar panels may be less suitable. For instance, if you live in an area with limited exposure to sunlight or have a roof that doesn’t face the right direction for optimal sun absorption, the benefits of solar panels may be less attractive.
However, for the majority of UK homeowners, the installation of solar panels offers an incredibly compelling opportunity. It’s your chance to embrace clean, renewable energy and revel in the myriad advantages it brings.
