The reason is quite simple. Despite the cloudy weather we are known for solar panels perform better in cooler temperatures and performance efficiency has improved massively in the last ten years.

Can solar panels be installed on any type of roof?

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.

How many solar panels does it take to run a house?

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.

What materials are used in solar panels?

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.

What happens with the electricity that I don’t use?

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.

What is the return on investment for solar panels?

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.

How much maintenance is required for solar panels?

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.
