Solar electricity refers to the generation of electricity using solar photovoltaic (PV) technology. Solar PV panels capture the sun's renewable energy and convert it into usable electricity.
How does a solar PV system work?
A solar PV system utilises an array of cells containing solar PV material that converts sunlight into direct current (DC) electricity. This electricity can be used to power lighting and electrical equipment in homes.
How many solar panels will my home need?
The number of solar panels required depends on factors such as energy usage, the size of the property, and the number of people living in the home.
Smaller homes may need a 1kW system with approximately 8+ square metres of roof space, while larger energy demands may require a 4kW system with 25+ square metres of roof space.
How does solar benefit the environment?
Solar energy is renewable, meaning it won't run out, and it is environmentally friendly as it does not produce greenhouse gases.
Utilising solar energy helps reduce carbon footprints and contributes to a cleaner environment.
What is a solar battery?
A solar battery is an additional component in a solar PV system that allows unused energy generated by solar panels to be stored. This stored energy can be used during night-time or periods when solar panels aren't producing electricity.
How much do solar panels cost?
The cost of solar panels can also vary depending on factors such as the size of the installation, the type and output of the panels, and the complexity of the installation process.
On average, a typical residential solar panel system in the UK can cost between £4,000 and £8,000 per kilowatt (kW) of installed capacity.
What is the cost of solar panels?
At E.ON, we offer two packages: the Energise package for unshaded roofs starts at £4,995 for a 6-panel system (2.37 kWp), while the Optimise package for shaded roofs starts at £6,578 for the same system.
What are the benefits of solar?
Solar energy offers a range of benefits, including being a renewable and clean energy source, providing cost savings on energy bills, offering energy independence, requiring low maintenance, creating jobs and economic growth, being scalable to different energy needs, reducing environmental impact, and providing incentives and rebates for installation.
Could you really charge an electric car for free using solar energy?
Charging an electric car using solar energy is not entirely free. Though solar panels generate electricity from sunlight, there are initial installation and equipment costs to consider. However, it can lead to long-term savings on electricity bills and offers a sustainable energy solution.
Do solar panels still work on cloudy days?
Yes, solar panels can still generate electricity on cloudy days. While direct sunlight is ideal, solar PV panels can convert the sun's radiation into electricity, even in less sunny conditions.
Do I need a south-facing roof for solar panels?
While a south-facing roof is considered optimal for maximising electricity generation, it is not strictly necessary. South-facing roofs receive direct sunlight during the most intense period (midday) and for a longer duration, enabling solar panels to harness the sun's energy more effectively.
How much roof space do I need for solar panels?
An 8-panel solar PV system can easily fit on the roof of an average 3-bed semi. Most panels generate a good amount of energy per m2, so you can still get plenty of electricity from a smaller roof.
Do I need constant sunshine for my solar panels to work?
No, solar panels work in all daylight conditions and actually work at their optimum at 10ºc. They may become inefficient if it gets too hot.
How do I compare different makes of solar panels?
Consider factors like aesthetics, value for money, performance, track record, and guarantees. Consult with engineers who can advise you on the panels that suit your needs.
What guarantees will my solar panels come with?
Solar panels come with a manufacturer's guarantee of performance. Different manufacturers offer different guarantees, usually associated with the more expensive panels. Make sure you understand the guarantee before purchasing.
How long will my solar panels last for?
Solar PV systems have long life spans. The inverter should last for over 10 years, and panels should last for at least 25 years. Extended warranties are available for the inverter.
How long does it take to install solar panels?
Most domestic installations take no more than a day with minimal disruption. Scaffolding is usually erected a couple of days before the installation. The panels are mounted on the roof, the inverter is installed, and internal wiring is carried out.
