When calculating how much solar energy you need, it is important to take into account a number of factors in addition to your average daily electricity consumption. These include your location, the orientation and tilt of your roof, and the efficiency of the solar panels you plan to install.
Shading is another important factor to consider, as even partial shading can significantly reduce the output of your solar panels. This can be caused by nearby trees, buildings, or other obstructions that block the sunlight from reaching your panels. A solar installer can help you identify any potential sources of shading on your property and recommend strategies for minimizing their impact.
It is possible for solar panels to cover all of your electricity consumption, but it depends on various factors such as the size of your property, the number of solar panels installed, and the amount of energy you consume. A professional solar installer can help you determine the number of solar panels needed to cover your electricity usage. However, even with enough solar panels, it may not be possible to generate enough electricity to cover your entire usage if you have high energy consumption or live in an area with limited sunlight.
It is important to note that even if solar panels cannot cover all of your electricity consumption, they can still significantly reduce your energy bills and contribute to a more sustainable future. In addition, excess solar energy can be stored in batteries or sold back to the grid through a process known as net metering. Overall, while it may not be possible to completely eliminate your reliance on the grid, solar panels can certainly make a significant difference in reducing your electricity bills and environmental impact.

Solar panels convert sunlight into electricity through the photovoltaic effect. When sunlight hits the photovoltaic cells in the panel, it creates an electric current that can be used to power homes and businesses.
The lifespan of solar panels can vary depending on a number of factors. On average, most solar panels have a lifespan of around 25-30 years, although some can last up to 40 years or more with proper maintenance. The quality and durability of the panels themselves play a significant role in determining their lifespan, as do factors like weather conditions and the amount of wear and tear they are subjected to over time.
While the initial cost of installing solar panels can be significant, their long lifespan means that they can be an excellent investment in the long run. Over the course of their lifespan, solar panels can generate a significant amount of energy, reducing your dependence on traditional energy sources and lowering your overall energy costs. With proper maintenance and care, solar panels can provide reliable and efficient energy for many years to come.
Our installers work with you to find an installation time that works around your schedule with the least possible disturbance. A few days before your installation date scaffolding will be erected. On installation day, a team of 2-3 technicians will come to your home, where they will typically spend one or two days fixing the panels to the roof. The length of installation depends on how big the roof is, what kind of security is needed for us to work safely, and what kind of roofing you have. The electrician then connects the system to the fuse box and puts the system into operation. Finally, your network company installs a new power meter which also records the power you send out to the network and must be have paid for.
Solar panels can be installed on many types of roofs, including flat roofs, sloped roofs, and even metal roofs. However, the installation process can be more complex on some roofs than others. For example, on a flat roof, solar panels may need to be tilted at a certain angle to optimise energy production. On a sloped roof, the angle of the panels may need to be adjusted to account for the roof's pitch. Additionally, on a metal roof, special mounting hardware may be required to ensure the panels are securely fastened.
Before installing solar panels on your roof, it is important to consult with a professional solar installer to assess the suitability of your roof and determine the best installation method. They can evaluate factors such as roof orientation, shading, and structural integrity to ensure that the panels will be able to generate the maximum amount of energy possible while also being installed safely and securely.
The number of solar panels required to power a house varies depending on the size of the property, the amount of energy consumption, and the efficiency of the solar panels. On average, a UK home would need between 10-20 solar panels to power the household.
The materials used in solar panels include silicon wafers, glass, aluminium frames, and various electrical components such as wiring and inverters. These materials are all environmentally friendly and recyclable, making solar energy a sustainable and renewable source of electricity.
Any excess electricity that is produced by your PV panels above your consumption can be sold back to the grid. Your automatic electricity meter calculates the sum of production and consumption hour by hour. If you have produced more than you have used, you will be paid for this by your electricity company.
The return on investment for solar panels can vary depending on several factors, including the cost of installation, the amount of energy the system generates, and the energy savings over time. Generally, solar panels can pay for themselves in 5-10 years and can continue to provide cost savings for many years after that.
Solar panels require very little maintenance. In fact, they are designed to be extremely durable and long-lasting. One of the reasons for this is that there are no moving parts in a solar panel system, which means that there is little that can go wrong. The panels themselves are made from tough materials like tempered glass, and the frames that hold them in place are made from aluminum or other metals that can withstand harsh weather conditions. In most cases, solar panels only need to be cleaned periodically to remove dirt and debris that can accumulate on the surface and reduce their efficiency. This can be done easily with a soft-bristled brush or a hose.
aluminiumAnother important aspect of solar panel maintenance is ensuring that the system is free from shade. Trees or other obstructions can cast shadows on the panels, which can significantly reduce their output. Regular trimming or pruning of nearby trees can help to prevent shading and keep the panels operating at maximum efficiency. Overall, solar panels require very little maintenance and can provide reliable energy for many years with minimal upkeep.
