d. Increased Property Value
Homes with solar panels often see a rise in property value. Potential buyers are attracted to the possibility of lower energy bills and the environmental benefits of solar energy, making your home a lot more attractive in the market.
e. Government Incentives
The UK government offers various incentives for those who choose solar module installation. These include the Smart Export Guarantee (SEG), which allows homeowners to earn money by selling excess energy back to the grid.
Types of Solar Panels
Before undertaking solar panel installation, it’s essential to understand the different types available:
a. Monocrystalline Solar Panels
Monocrystalline panels are the most efficient type and are known for their high performance, even in low light conditions. They are more expensive but offer a higher energy yield per square meter.
b. Polycrystalline Solar Panels
Polycrystalline panels are less efficient than monocrystalline but are more affordable. They are suitable for larger spaces where efficiency is less of a concern.
c. Thin-Film Solar Panels
Thin-film panels are the least efficient but are more flexible and lightweight. They are ideal for solar module installation on unconventional surfaces or areas with space limitations.
The Solar Panel Installation Process
a. Initial Consultation and Site Survey
The solar panel installation process begins with a consultation and a site survey. A professional installer will assess your property’s suitability for solar panels, including the roof’s orientation, shading, and available space.
b. Design and Planning
Based on the site survey, the installer will design a system tailored to your energy needs and the property’s specifications. This includes calculating the number of panels required, system size, and placement.
c. Permits and Approval
In some cases, planning permission is required, especially for listed buildings or properties in conservation areas. Your installer will handle any necessary approvals from local authorities.
d. Installation
The actual solar panel installation process usually takes one to three days, depending on the complexity of the system. The panels are mounted on the roof using a racking system, and an inverter is installed to convert the DC electricity generated by the panels into usable AC electricity.
e. Connecting to the Grid
Once installed, the system is connected to the grid. If you’re eligible for the SEG, you can start selling excess electricity back to the grid, further increasing the return on your investment.
f. System Testing and Commissioning
After solar panel installation, the system is thoroughly tested to ensure everything is working correctly. The installer will guide you through the system’s operation and provide the necessary documentation.
Maintenance and Longevity of Solar Panels
Solar panels are relatively low-maintenance, but periodic checks are necessary to ensure they operate at maximum efficiency. Here’s what you should consider:
a. Cleaning
Dirt and debris can reduce the efficiency of solar panels. Cleaning them at least twice a year is recommended to ensure optimal performance.
b. Inverter Maintenance
The inverter is a crucial component of your solar system. It typically lasts 10-15 years, so it may need replacing before the panels themselves, which have a lifespan of 25-30 years.
c. Monitoring System Performance
Most modern solar systems come with monitoring apps that allow you to track energy production and spot any issues early.
Costs Involved in Solar Panel Installation
The cost of solar panel installation in the UK can vary depending on several factors, including the size of the system, the type of panels, and the complexity of the installation. On average, the cost of installing a 4kW system ranges from £5,000 to £6,000.
a. Factors Affecting Cost
- System Size: A typical 4kW solar panel system, including installation, costs £5,000 – £6,000. Added together, the total cost of solar panels and a battery in the UK is £13,000-£15,500.
- Type of Panels: Monocrystalline panels are more expensive than polycrystalline and thin-film options.
- Roof Type: Complex roof structures or materials may increase installation costs.
- Battery Storage: Adding a solar battery can significantly increase the cost but offers the advantage of storing excess energy for later use.
b. Government Incentives and Financing Options
To make solar module installation more affordable, the UK government offers various incentives, including the Smart Export Guarantee (SEG) and VAT reductions on solar installations. Many companies also offer financing options to spread the cost over time.
Solar Battery Storage: Maximizing Efficiency
Solar battery storage systems allow you to store excess electricity generated during the day for use at night or during cloudy days. This can further reduce your reliance on the grid and increase your energy independence.
a. Types of Solar Batteries
- Lithium-ion Batteries: We can call this type “the new kid on the block”, compared to the much longer history of lead-acid batteries. It has been improved in parallel to the developments in battery technology required for electric cars in recent years.
- Lead-acid Batteries: This type is the oldest solar battery type. Thanks to its long history, it has been developed alongside clean energy resources. Lead-acid solar batteries come in two different types. Sealed lead acid batteries are designed in a way that they reduce the release of toxic gas into the atmosphere, during their charging process.The second lead-acid battery type is flooded lead acid battery. This is like the bigger version of a traditional car battery.
- Flow Batteries: Another new kid on the block, truly a new player in the solar battery technology scene is the flow battery. Despite the fact that it is a fairly new storage solution, and it still requires improvements, there are a couple of points that make flow batteries a popular option. Its depth of discharge is 100%. So, you can use the entire stored energy.
b. Benefits of Solar Battery Storage
