The photovoltaic effect is what’s known as a thermodynamic process. Solar panels directly convert sunlight into electricity and are formed of photovoltaic cells, which are usually made of silicon. When sunlight strikes the cells, the photons from the sunlight are absorbed by the atoms in the silicon material. This absorption excites electrons in the silicon, causing them to move and create an electric current. The electric current is then captured and can be used to power electrical devices or sent to the grid for distribution.

The cost of solar panels can vary significantly depending on factors such as the size of the system and your specific energy requirements. For a more accurate estimate tailored to your needs, we recommend completing our quick remote survey to receive detailed pricing information.

UPS Solar panels typically last 25-30 years, retaining at least 80% of their power output. With good quality, favorable conditions, and proper maintenance, their lifespan can be even longer. UPS Solar offers a 25-year manufacturer warranty and a 25-year performance guarantee to protect your investment.

The energy a solar panel system produces depends on its size, panel efficiency, and sunlight exposure. In the UK, a 4kW system typically generates 3,400 to 4,200 kWh annually, enough to cover an average household’s electricity needs. Actual output can vary based on installation conditions and weather.

South-facing roofs (south-east, south, south-west) are the most efficient for solar panels, but flat roofs and ground-mounted systems are also viable. It’s crucial that the installation area has minimal shading and gets sunlight most of the day.

Cleaning your solar panels regularly maximises their efficiency by ensuring they absorb the most sunlight. Dust, dirt, and bird droppings can reduce their effectiveness. Panels typically need cleaning once a week. In dry areas, manual cleaning is required, while in rainier regions, natural cleaning is often sufficient.
