A Guide to Solar Energy in Wales

A Guide to Solar Energy in Wales



Sunlight, a seemingly endless resource, can be transformed into clean, renewable electricity for your home or business. This guide explores solar energy in Wales, explaining how it works, its benefits, government support, and how you can join the solar revolution.

What is Solar Energy?

Imagine capturing the sun's rays and converting them into electricity. That's the magic of solar energy! Solar panels, made from photovoltaic (PV) cells, absorb sunlight. These cells then convert the captured light energy into a direct electric current (DC).

Here's a breakdown of the process:

1. Sunlight hits the PV cells: The sunlight interacts with the materials in the cells, causing electrons to move.
2. Electrons flow: This movement of electrons creates a direct current (DC) electricity.
3. Inverter steps in: Most homes and businesses use alternating current (AC) electricity. An inverter converts the DC electricity from the panels into usable AC electricity.
4. Power your home/business: The converted AC electricity can then be used to power your appliances, lights, and other electrical devices.

What are the two main ways to utilise solar energy?

• Grid-connected systems: These systems connect to the national grid. During the day, your solar panels generate electricity, which you can use in your home or business. Any excess electricity is exported back to the grid, potentially earning you a feed-in tariff payment from your energy supplier. At night or during low sunlight periods, you can draw electricity from the grid as usual.
• Off-grid systems: These standalone systems are ideal for remote locations without access to the national grid. They typically include batteries to store excess solar energy generated during the day for use at night or during cloudy periods.

What are the Benefits of Solar Power for Homes and Businesses?

Solar energy offers a versatile solution for both homes and businesses:

• Homes: Reduce your electricity bills and your carbon footprint. Generated solar power can significantly offset the amount of electricity you need to buy from the grid, leading to lower electricity bills.
• Businesses: Showcase your commitment to sustainability and potentially reduce running costs. Solar panels can help businesses project a more environmentally friendly image and potentially save money on electricity bills.

Beyond cost savings, here are some additional benefits of solar energy:

• Clean and renewable: Solar energy produces no harmful emissions, contributing to a cleaner environment and a more sustainable future.
• Low maintenance: Once installed, solar panels require minimal upkeep.
• Increased property value: Homes with solar panels can potentially fetch a higher price in the property market.
• Energy security: By generating your own electricity, you become less reliant on fluctuating energy prices.

What is Welsh government doing to help homes and businesses to install solar?

The Welsh Government recognises the potential of solar energy and offers a couple of financial incentives to encourage its adoption:

• The Energy Company Obligation (ECO4) Scheme: This scheme provides grants to eligible households for energy efficiency improvements, which can include solar panel installations.
• The Nest scheme: This grant programme supports the development of renewable energy projects in Wales. While not directly targeted at individual households, it helps create a supportive environment for solar energy growth.

These grants can significantly reduce the upfront cost of installing solar panels, making them a more accessible option for many homeowners. It's important to note that grant availability and eligibility criteria can change, so be sure to check the latest information from the Nest or Ofgem websites.

The Welsh Government has set ambitious renewable energy targets, aiming to generate 70% of Wales' electricity from renewable sources by 2030. Solar energy plays a crucial role in achieving this goal.

How is the Welsh Government supporting the growth of solar energy?

• Planning permission: Streamlining the planning process for solar panel installations.
• Supporting community-owned renewable energy projects: Encouraging communities to come together and invest in solar energy projects.
• Investing in public sector solar installations: Adding solar panels to public buildings to lead by example.

These initiatives demonstrate the Welsh Government's commitment to making solar energy a viable option for homes and businesses across Wales.

Is Solar Right for Me?

Here are some questions to consider before deciding on solar panels:

• Your roof: South-facing, unshaded roofs are ideal for maximising solar energy capture.
• Your electricity usage: Consider your average daily electricity consumption to determine the size and capacity of the solar panel system you might need.
• Your budget: While there's an initial investment, solar panels can pay for themselves over time through the savings you make on your electricity bills. The payback period will depend on the size of your system, your electricity usage, and the amount of sunlight your roof receives.
• Getting quotes: It's important to get quotes from several reputable solar panel installers to compare prices and find the best deal for your needs. At HSB we offer free quotes. Use the green tab to get a quote.
• Finding a qualified installer: Make sure the installer you choose is accredited by the Microgeneration Certification Scheme (MCS). This ensures they meet the necessary standards for quality and safety. HSB is a MCS Approved Contractor and is a member of HIES.

Additional Considerations:

• Planning permission: In most cases, you won't need planning permission to install solar panels on your roof. However, it's always best to check with your local planning authority to be sure.
• Building regulations: There may be building regulations that apply to solar panel installations. Your installer will be able to advise you on this.
• Roof suitability: Not all roofs are suitable for solar panels. Your installer will assess your roof to ensure it can safely support the panels and that it receives enough sunlight.
• Shading: Solar panels work best in direct sunlight. Shading from trees, chimneys, or other structures can significantly reduce their efficiency.
• Battery storage: If you're considering an off-grid system or want to maximise your use of solar energy, you might want to consider installing battery storage. This will allow you to store excess solar energy generated during the day for use at night or during cloudy periods.

Making an Informed Decision

By considering the factors mentioned above, you can make an informed decision about whether solar energy is right for you. There are a number of resources available to help you learn more about solar energy in Wales, including:

• The Energy Saving Trust: https://energysavingtrust.org.uk/
• The Welsh Government: https://www.gov.wales/
• The National Solar Centre: https://www.bre.co.uk/nsc/index.jsp

Solar energy is a rapidly growing technology that offers a clean, sustainable, and cost-effective way to power your home or business. By taking advantage of the resources available and considering your individual circumstances, you can decide if solar panels are a bright addition to your future.
