What You Need to Know Before Getting Solar Panels
Solar energy is gaining traction across the UK as more homeowners seek sustainable and cost-effective energy solutions. However, before making the commitment to install solar panels, it’s essential to have clear and reliable information. Here, we cover the practical considerations, costs, suitability, and long-term expectations of solar panel installation, with insights from our trusted local experts at Voltify Solar.
How Do Solar Panels Work?
Understanding the basics of how solar panels function is crucial. Solar panels convert daylight into electricity, meaning they don’t require direct sunlight to operate effectively. An inverter then converts the direct current (DC) electricity generated by the panels into alternating current (AC) power, which can be used in your home. Additionally, optional battery storage can store unused energy, and any excess electricity can be exported back to the grid. This process is straightforward and doesn’t require technical jargon to grasp.
Is Your Home Suitable for Solar Panels?
Determining your home’s suitability for solar panels is a key step in the decision-making process.
Roof Direction & Angle
Ideally, a south-facing roof is optimal for solar panel installation, but east and west orientations can also yield good results. Most UK roofs have a pitch that works effectively for solar panels.
Shading
Consider potential shading from trees, chimneys, or neighbouring buildings, as these can reduce the output of your solar panels.
Roof Condition
Ensure your roof is in good structural condition. If necessary, consider re-roofing before installation to avoid future complications.
Available Space
A typical domestic solar system requires 10–20 panels. More available space can increase your energy generation potential.
Frequently Asked Questions
How Much Do Solar Panels Cost in the UK?
While exact pricing can vary, it’s important to understand the components of solar panel costs. These include the upfront installation cost, optional battery storage cost, and potential long-term savings. The typical payback period can vary based on your energy usage. Costs depend on factors such as system size, property type, and energy consumption.
What Savings Can You Expect?
Investing in solar panels can lead to reduced electricity bills and protection from rising energy prices. You may also benefit from the Smart Export Guarantee (SEG) payments for surplus electricity. Greater savings can be achieved when your energy usage aligns with daytime production. However, it’s important to note that savings can vary by household.
Do You Need Planning Permission?
Most UK domestic solar panel systems fall under permitted development, meaning no planning permission is required. Exceptions include listed buildings, conservation areas, and installations on flat roofs or unusual structures. If you’re unsure, it’s advisable to check with your local authority.
How Long Do Solar Panels Last?
Solar panels typically have a lifespan of 25+ years, with inverters lasting 10–15 years. Performance warranties are often included, and maintenance requirements are generally low, reinforcing the reliability and long-term value of solar panels.
Maintenance & Servicing Considerations
Solar panels require minimal maintenance. Occasional cleaning may be beneficial, and a professional inspection every 1–2 years is recommended. Monitoring systems can help homeowners track performance and ensure optimal operation.
Battery Storage: Is It Worth It?
A solar battery stores excess energy, providing benefits for households that use energy in the evenings. While adding a battery increases costs, it also enhances energy independence.
Common Mistakes to Avoid When Getting Solar Panels
• Choosing solely based on the lowest price
• Not checking installer accreditation
• Overestimating savings without reviewing energy usage
• Installing on a roof that may soon need repairs
• Ignoring future energy needs, such as electric vehicles or heat pumps
Questions to Ask Before Installation
To ensure you have all the necessary solar power information, consider asking the following questions before installation:
• What size system do I need?
• What warranties are included?
• Is the installer MCS-certified?
• What monitoring tools are provided?
• What aftercare is offered?
Is Solar Right for You?
Solar panels may be a suitable choice if you own your home, have a suitable roof, plan to stay long term, want to reduce bills and your carbon footprint, and understand the upfront investment involved. The decision should be informed and balanced, focusing on your specific circumstances and goals.
