Discover the Power of Solar Panels for Your Home

Solar panels offer a powerful solution to reduce your electricity bills, shrink your carbon footprint, and lessen reliance on the National Grid.

What’s more, the cost of solar panels continues to decline over time.

In this comprehensive guide, we’ll walk you through everything you need to know about installing solar panels on your property. From understanding what they are to assessing if they’re the right fit for your home, we’ll cover the essential aspects, including associated costs and potential savings in different regions of the country.

With a staggering 17,000 solar panel installations occurring every month, there’s no better time to explore the benefits of solar energy. If you’re ready to take the next step and compare solar panel prices, simply provide a few quick details, and our team of expert installers will reach out with free quotes for you to compare.

Solar panels, also known as photovoltaic (PV) panels, are devices that convert sunlight into electricity, providing a renewable energy source for powering homes. These panels consist of cells made from semiconducting materials, predominantly silicon, which absorb sunlight and generate an electric charge. This charge is then converted into direct current (DC) electricity. Since most homes use alternating current (AC) electricity, inverters are installed alongside solar panels to convert DC to AC, making it compatible with household electrical systems.

Despite the initial cost, solar panels offer substantial benefits. They continue to generate electricity even on cloudy or snowy days, although they are most efficient under direct sunlight. Excess energy produced on sunny days can be stored in solar batteries for later use or sold back to the grid through programs like the Smart Export Guarantee (SEG). Moreover, solar panels typically have a lifespan of at least 25 years, with some models even offering a lifetime guarantee.

In the UK, solar panels perform well, even in regions with less sunlight. On average, a three-bedroom household equipped with 10 solar panels can reduce its electricity bills by 70%, breaking even on the investment in just 14.6 years. The efficiency of solar panels has been increasing rapidly, requiring less sunlight to generate sufficient energy for homes, which is advantageous given the UK’s climate. Additionally, the risk of panels overheating is minimal in the UK, ensuring consistent efficiency.

While solar panels produce more electricity in countries with greater sun exposure, such as those to the south of the UK, they remain highly profitable in the UK. This highlights the advancements in solar technology over the years, making solar energy a viable and sustainable option for homeowners across the country.

Determining whether solar panels are a suitable addition to your home entails considering several factors. Firstly, assess your roof’s space and orientation. Ideally, your roof should have ample space and face south for optimal sunlight exposure. However, east or west-facing roofs can also suffice. Additionally, the angle of your roof plays a crucial role, with angles between 35° and 45° generally regarded as ideal.

To ensure optimal performance, it’s essential to install the correct number of solar panels based on your household’s energy needs and available roof space. While solar panels require an initial investment, they typically yield substantial long-term savings. Our latest calculations indicate that the average household recoups its investment in solar panels after 14.6 years. Therefore, committing to solar panels is most advantageous for homeowners planning to reside in their current property for an extended period.

Moreover, investing in solar panels can enhance the value of your home. According to our recent National Home Energy Survey, 69% of individuals express a preference for properties equipped with solar panels. Additionally, numerous studies have demonstrated that solar panels positively impact property values. Thus, incorporating solar panels into your home can be both financially rewarding and enhance its desirability in the housing market.

Determining the optimal number of solar panels for your home is crucial for maximizing cost-effectiveness and energy efficiency. Typically, a one or two-bedroom house will require six solar panels to establish an efficient system, while a standard three-bedroom house would benefit from the installation of 10 panels. Larger residences, such as four or five-bedroom homes, usually necessitate 14 panels to meet their energy needs adequately.

In these scenarios, the solar panels installed can generate enough electricity to cover approximately 46% of an average household’s annual usage. However, actual usage may vary depending on factors like daily energy consumption habits and lifestyle.

Regarding the integration of a solar battery into your system, it’s a prudent choice only if your electricity consumption significantly exceeds the average. While adding a battery can yield an additional £132 in annual electricity bill savings for the average household with solar panels, it’s essential to consider the upfront costs. Solar batteries typically range between £2,500 and £5,500, making it challenging to break even unless your energy consumption is notably high compared to typical households.

When considering the investment in residential solar panels, it’s crucial to understand the associated costs. On average, each residential solar panel costs £786. For a standard three-bedroom household, a 3.5 kilowatt-peak (kWp*) solar panel system, comprising 10 panels, is usually the optimal choice. This system typically costs around £7,860. However, the total cost may vary depending on the number of panels required, ranging from £4,700 to £11,000 for households requiring between six and 14 panels.

According to data from the Microgeneration Certification Scheme (MCS), the average cost per kWp of solar panels is £2,246. Understanding these costs and considerations is essential for making informed decisions regarding residential solar panel installations.

Solar Panel Installation Process:

Installing solar panels involves a meticulous seven-step process. Initially, scaffolding is set up to ensure safe access to the roof. Roof anchors are then attached to secure the solar panel mounts, providing stability during extreme weather conditions. Solar panel mounts are subsequently affixed to support the panels optimally for sunlight exposure. Finally, the inverter is connected to the solar panels and consumer unit, followed by thorough testing to ensure seamless functionality of the entire system.

1. Install Solar Panels:

Installation of solar panels involves meticulous attention to detail. Your installer will adeptly position the solar panels onto the mounting system, ensuring optimal alignment and securely fastening all bolts and nuts across the system to ensure stability and longevity.

2. Connect the Inverter to Your Solar Panels:

The inverter, a crucial component of the solar panel system, is seamlessly connected to the solar panels by your installer. This pivotal device efficiently converts the direct current (DC) electricity generated by the panels into alternating current (AC), compatible with your home’s electrical grid. This step, which typically takes 4-6 hours, demands professional expertise to prevent system failure or potential hazards like house fires.

3. Connect the Inverter to Your Consumer Unit:

Following the inverter connection, your installer proceeds to link the inverter to a circuit-breaker within your consumer unit, also known as a fuse board. This essential connection enables your home to harness solar-generated electricity, contributing to energy efficiency and cost savings. Additionally, if your inverter lacks a built-in generation meter, your installer may integrate one during this stage to monitor electricity production accurately.

4. Test the Solar Panel System:

Completion of the installation is marked by a comprehensive testing phase conducted by your installer. This meticulous testing ensures the seamless functionality of every component within the solar panel system. From switching the power back on to monitoring each part of the network, thorough testing guarantees optimal performance and peace of mind for homeowners.
