Your Ultimate Guide to Solar Power in South Wales: Save Money and Energy with Solar Panels
Why Solar? Solar energy is an increasingly popular choice in South Wales due to the region's suitable climate and strong governmental support for renewable energy. With around 1,700 hours of sunshine annually in areas like Pembrokeshire, solar panels can generate significant amounts of electricity even in the Welsh climate. The Welsh government is also committed to increasing renewable energy generation to 70% by 2030, making solar power a key component of this strategy.
How This Guide Can Help You Make the Switch: This guide will walk you through the benefits, costs, and steps to installing solar power in your home, ensuring you can make an informed decision about going solar.
Solar Energy 101: What You Need to Know
What Exactly is Solar Energy? Solar energy is harnessed from the sun’s rays using photovoltaic (PV) panels, which convert sunlight into electricity. This renewable source of energy is clean, abundant, and reduces reliance on fossil fuels.
How Solar Panels Work: Solar panels work by converting sunlight into electricity through a process called the photoelectric effect. The panels are typically made from silicon and absorb the sun's energy creating an electric charge, the direct current (DC) produced is converted to alternating current (AC) by an inverter. The panels work in any weather even during cloudy days but produce more energy when there's more sunshine.
Solar Panel Design: Solar panel dimensions are typically around 2m x 1m and can be orientated in portrait or landscape. They can be fitted within a roof using a tray or on top of a roof with a rail system.
Maximising Solar Efficiency with Smart Technology
Using Home Automation to Monitor and Manage Solar Energy: Smart home systems allow you to monitor your solar energy production in real-time, optimise energy use, and manage your home’s energy consumption more efficiently.
How Smart Devices Can Help You Save Even More: Devices like smart thermostats and energy management systems can further reduce energy costs by ensuring that solar energy is used most efficiently when it is being produced.
Integrating Solar Power with Your Home’s Energy System: Modern solar inverters and optimisers can integrate seamlessly with home automation systems, allowing for better control and maximisation of energy efficiency.
Is Solar Power Right for Your Home?
Assessing Your Home’s Solar Potential: Consider factors such as roof orientation, shading, and available roof space. South-facing roofs are ideal, but east or west-facing roofs can also be effective. A typical home will need around 8–12 solar panels depending on energy usage and roof space.
The Impact of South Wales’ Climate on Solar Efficiency: Despite the reputation for cloudy weather, South Wales receives enough sunlight to make solar panels a viable investment, with average savings of up to £477 per year on electricity bills.
Solar Power for Different Types of Homes: Whether you live in a detached house or a terrace, solar panels can be customised to fit your roof and energy needs.
The Benefits of Going Solar
Reducing Your Energy Bills: Solar panels can cut electricity bills by up to 74% on average for Welsh homes. Over the system’s lifetime, this can result in significant savings that outweigh the initial installation costs.
Increasing Your Home’s Value: Homes with solar panels are increasingly attractive to buyers, with 69% of people likely to buy a property with solar panels installed.
Contributing to a Greener South Wales: By switching to solar, you reduce your carbon footprint, helping to combat climate change and contribute to Wales’ renewable energy targets.
Planning Your Solar Installation
How to Get Started with Solar: A Step-by-Step Guide: Begin with a site assessment to determine your home’s suitability for solar panels. Then, design and plan your system, considering the number of panels, inverter placement, and necessary permissions.
Navigating Local Regulations and Planning Permissions in South Wales: Most solar installations are considered permitted developments, but check with your local council if your home is in a conservation area or listed building.
Finding Trusted Solar Installers Near You: Ensure your installer is certified by the Microgeneration Certification Scheme (MCS) to qualify for grants and incentives.
Questions to ask your Installer: What is the chosen Panel capacity, efficiency and appearance? The higher the capacity the more energy you can extract from a single panel, the more efficient means less energy lost in the process and panels can be all black or have silver outlines and frames. Where will the inverter be placed? Usually in the loft or garage, they can be placed outside too. Are batteries worth adding to the installation? Batteries can add further significant savings but need to be sized correctly to your installation and energy consumption. How long will installation take? Typically 2 to 5 days depending on size and complexity. What are the warranties on equipment and installation? Manufacturers offer on average a 10 year warranty policy. Installation usually for the first year.
Smart Meter: Having a smart meter is required to benefit from the SEG (Smart Export Guarantee). If your system produces more energy than you require, the excess can be sold back to the grid/ energy company. A smart meter allows the accurate monitoring of energy flow half hourly to enable this process.
Energy Usage: Various models can be used to calculate average household energy usage, although it's more accurate to use the amount of Kwh used per annum from your meter or electricity bill.
Grants
ECO4 Scheme: This scheme offers significant financial support for low-income households to install solar panels. You may be eligible for up to £10,000 towards solar panel systems if you meet specific income and benefit criteria. The scheme targets homes with low energy efficiency to upgrade with a range of energy efficient measures. Homes below an energy rating of D are eligible.
Nest Scheme: Provides free energy efficiency improvements, including solar panels, to eligible households. This scheme is particularly aimed at households with high heating costs or residents with long-term health conditions.
Smart Export Guarantee (SEG): Sell excess energy back to the grid and reduce your payback period. All energy suppliers have different export tariffs and you don't have to be with the same energy supplier for both import and export.
Zero VAT on Solar Installations: The UK Government has reduced VAT on solar panel installations to 0% until March 2027, making it more affordable to switch to renewable energy.
Understanding Your Solar Equipment: A Simple Guide
Solar Panels: The most visible part of your system, solar panels convert sunlight into electricity. Types include monocrystalline, polycrystalline, and thin-film panels, with monocrystalline being the most efficient.
Inverters: These devices convert the direct current (DC) generated by your panels into alternating current (AC) for use in your home. Options include string inverters, microinverters, and hybrid inverters.
Optimisers: Power optimisers ensure that each panel operates at its maximum potential, especially useful in areas where shading may affect panel performance.
Batteries: Solar batteries store excess energy generated during the day for use at night or during periods of low sunlight, providing energy independence and further reducing reliance on the grid.
Maintenance Made Easy: Keeping Your Solar System Running Smoothly
Minimum to no maintenance required, a large accumulation of bird droppings will affect performance and will need to be cleaned off. Periodic inspection between the panels and the roof if using rails without bird guard can identify any accumulation of nest / debris etc which may affect cooling.
