In the era of sustainable energy, exploring renewable sources is more important than ever. Solar panels, while a popular option, can be a conundrum to many homeowners. How do they work? Where should they be installed? What’s the best orientation for solar panels? You might be wrestling with these questions if you’re considering solar power. In this article, we’ll discuss the best practices for installing residential solar panels, specifically for homes in Northern UK.
Choosing the Right Solar Panel System
Before you get into the nitty-gritty of installing solar panels, it’s crucial to first understand the different types of solar systems available and identify the one that’s most suitable for your needs. The primary types of solar systems include grid-tied, off-grid, and hybrid systems.

Grid-tied systems are the most common type of solar system in urban areas. They are connected to the local electricity grid and allow you to feed any excess energy produced by your system back to the grid. This can help offset your electricity costs.
Off-grid systems, on the other hand, operate independently of the local electricity grid. They are best suited for remote locations where grid connectivity may be limited or non-existent.

Hybrid systems are a combination of the two. These systems are connected to the grid but also include a battery storage component. This allows you to store excess energy for use during power outages or during times when the panels aren’t producing electricity (such as at night).
Selecting the Best Location on Your Roof
When it comes to installing solar panels, location is key. The best spot for solar panels is generally a south-facing roof. This is because the UK is in the Northern Hemisphere, and for most of the year, the sun is to the south of us. However, if a south-facing roof isn’t available, an east or west-facing roof can also work, though they may not be as efficient.
The angle of your roof also matters. The optimal angle for solar panels in the UK is generally around 30 to 40 degrees. This angle allows the panels to capture the maximum amount of sunlight throughout the day.
Shade is another important factor to consider. Panels should be installed in an area that’s free of shade for the majority of the day to ensure they can produce the maximum amount of electricity.
Calculating the Costs and Potential Savings
Before proceeding with the installation, it’s important to calculate the cost of the system and the potential savings you could make.
The cost of a solar panel system will depend on several factors including the size of the system, the type of panels, and the cost of installation. The average cost of a solar panel system in the UK is typically between £4,000 and £6,000.
The potential savings from solar panels can also vary greatly depending on factors like the amount of sunlight your house receives, the cost of electricity in your area, and the size of your system. However, on average, a solar panel system can save a UK homeowner between £85 and £220 per year on their electricity bill.
Preparing Your Home for Installation
Once you’ve chosen a system and location and have calculated the costs, the next step is preparing your home for the installation. This may involve reinforcing your roof to handle the weight of the panels, installing the necessary wiring, and obtaining any necessary permits.
It’s also advised to have a professional assess your roof to ensure it’s suitable for solar panel installation. They will check for any issues that could affect the installation, such as structural weakness, dampness, or rot.
Choosing a Reputable Installer
The final step in the process is finding a reputable installer to carry out the job. Choose an installer who is certified by the Microgeneration Certification Scheme (MCS), as this guarantees that they meet the necessary standards for solar panel installation.
Look for installers who have been in the business for several years, have good customer reviews, and offer a warranty for their work. They should also offer a comprehensive service that includes post-installation maintenance and support.
In conclusion, installing solar panels in your home is an investment that pays off in the long run. While the initial costs may be significant, the long-term savings on your energy bills, coupled with the environmental benefits, make it a worthwhile endeavour. The key is to be informed and prepared before embarking on this journey.
Maximizing Output with Smart Export Guarantee (SEG)
Getting the most out of your solar panel system can also involve making use of the Smart Export Guarantee. The SEG is a government scheme in the UK that pays homeowners for the excess electricity they generate from their solar panels and feed back into the grid.
To qualify for the SEG, you need to have a solar panel system that’s MCS-certified and an energy meter that can measure how much electricity you’re exporting. Most importantly, you need to be with an energy supplier that offers the SEG. Many UK energy suppliers, including all the big six (British Gas, EDF Energy, EON, Npower, Scottish Power, SSE), offer this scheme.
The rate you’ll be paid per kilowatt-hour (kWh) of exported electricity varies depending on your energy supplier and the tariff they offer. The SEG can be a great way to further reduce your energy bills and make your investment in solar power even more worthwhile.
Leveraging Solar Battery Storage Systems
Another way to increase the efficiency of your solar panel system is by installing a solar battery storage system. These batteries store excess power generated by your solar panels for use at times when the panels aren’t generating power, such as during the night or on cloudy days.
Solar batteries can be particularly useful if you’re unable to make use of the SEG because you do not export much electricity back to the grid, perhaps because you use most of it in your home.
Furthermore, in the event of a power cut, a solar battery will ensure that you still have a supply of electricity, making your home more resilient and independent.
Solar batteries, however, do add to the upfront cost of a solar panel system, and it may take some time before the savings from the stored energy cover the cost of the battery. It is, therefore, recommended to carefully consider your energy usage patterns, electricity costs, and potential savings before investing in a solar battery storage system.
Conclusion
In summary, installing solar panels in your home can be a smart way to reduce your energy bills, earn money through the Smart Export Guarantee, and contribute to a more sustainable future. However, it is important to make considered decisions regarding the type and size of the solar panel system, its placement on your roof, the potential use of a solar battery, and the choice of a reputable installer. By following these best practices, you will be well on your way to harnessing the power of the sun and making the most of renewable energy in Northern UK. Remember, solar energy is not just a means of generating electricity, it’s a long-term investment that offers both financial and environmental benefits.
