At Solar Panel Help UK, we understand that investing in solar photovoltaic (PV) panels is a big decision. Solar energy is an excellent way to reduce your electricity bills, lower your carbon footprint, and increase your energy independence. However, it's essential to ensure you're making the right choice for your property and needs. Below, we’ve outlined the key factors to consider before getting solar PV in the UK.
1. Your Roof's Suitability
Before installing solar panels, it's important to assess whether your roof is suitable for solar energy.
Consider:
Orientation: South-facing roofs tend to generate the most energy, but east or west-facing roofs can also work efficiently.
Angle: Ideally, your roof should have a tilt between 30 and 40 degrees to maximise sunlight exposure.
Shading: Trees, nearby buildings, and chimneys that cast shadows on your roof can reduce the effectiveness of your solar panels.
Space Available: Ensure there is enough space for the panels. A typical solar PV system requires around 20–30 square meters.
2. Local Climate
While the UK isn’t known for endless sunshine, modern solar panels work efficiently even on cloudy days. Solar PV systems generate energy from daylight, not just direct sunlight. However, the amount of energy generated can vary based on your location within the UK, with southern areas generally receiving more sunlight.
3. Energy Consumption
Evaluate your household’s energy usage to determine the size of the system you need.
Consider:
How much electricity you use daily.
Whether you're at home during the day (when solar panels generate the most energy).
Consider a home battery if energy is used more so in the evening.
Whether you plan to use the energy for appliances, heating, or even charging an electric vehicle.
This information will help you choose a system size that can maximise savings.
4. Solar Panel Costs & Incentives
The initial cost of installing solar panels has decreased in recent years, making it a more affordable option for UK homeowners. When considering the costs, think about:
Installation and Equipment Costs: Solar PV systems typically cost between £4,000 and £10,000, depending on the size and components.
Government Incentives: The Smart Export Guarantee (SEG) allows you to sell excess electricity back to the grid, generating additional income.
Payback Period: On average, solar PV systems pay for themselves within 9–12 years, depending on energy savings and incentives.
5. Maintenance and Lifespan
Solar panels require very little maintenance, but it’s worth considering their long-term care. Panels generally come with warranties of around 25 years, and they only need occasional cleaning to ensure optimal performance. You should also check for any local weather-related risks, such as extreme storms or heavy snowfall, which could affect panel efficiency.
6. Energy Storage Options
To maximise the benefits of solar power, consider investing in a solar battery storage system. This allows you to store excess energy generated during the day for use at night or during peak demand periods. While this increases the upfront cost, it can significantly boost your energy independence and savings over time.
7. Planning Permissions
In most cases, installing solar panels on a residential property in the UK doesn't require planning permission. However, if you live in a listed building, a conservation area, or have other specific restrictions, you may need to check with your local council before proceeding.
8. Environmental Impact
By installing solar PV, you're making a significant contribution to reducing your carbon footprint. On average, a solar panel system can save approximately 1.3–1.6 tonnes of CO2 per year, making it a great option for environmentally-conscious homeowners.
9. Choosing the Right Installer
Working with a trusted, certified installer is crucial for the long-term success of your solar system. Ensure your installer is MCS-certified and provides a comprehensive service, from system design to installation and aftercare. At Solar Panel Help UK, we pride ourselves on offering reliable and professional solar PV installation services tailored to your needs.
