Can I put solar panels on a garage roof in the UK?

Yes! The great news is that solar panels can be installed on a garage roof in the UK. However, the number of panels you can fit will depend on the available space and the size of your garage.

On average, garage solar panel installations in the UK that can accommodate 4 to 6 panels can range from £3,500 to £6,000. So, let’s explore how many solar panels you can actually install on your detached garage roof.

How many solar panels can you fit on a detached garage roof?

The first step is to assess the available space on your detached garage roof. Garages come in various shapes and sizes, so the number of solar panels you can install will largely depend on the roof’s dimensions.

Ideally, you’ll want an unobstructed area with maximum exposure to sunlight throughout the day. The table below will guide you on the number of solar panels required for your garage roof.

Size of system	No. of panels	Estimated Panel area (m2)	Garage Roof area required (m2)
2 kW	8	12.8	Single Garage 3mx5m (15m2)
3.00 – 3.50 kW	12-14	17 – 23	Double Garage 5.5mx5m (27.5m2)

Considerations for optimal placement

To fill the potential of your solar panels, their placement is crucial. South-facing roofs receive the most sunlight throughout the day in the UK, making them an ideal choice for solar installations. However, east and west-facing roofs can still be viable options, and modern solar panel technology is efficient enough to generate significant power even with slightly less than optimal orientations.

Calculating solar panel capacity

Now, let’s crunch some numbers. The capacity of a solar panel is typically measured in watts (W) or kilowatts (kW). An average solar panel in the UK can produce around 250 to 400 watts of electricity. So, the total capacity of your solar system will depend on the combined capacity of all the panels you install.

Let’s see this simple example:

Daily watt hours = Average hours of sunlight × solar panel watts × 85%.

(As not all the sunlight is converted into electricity. As we have tested to determine that most solar panels are 85% efficient.)

So, suppose you live in an area with 5 hours of peak sunlight, and your panel has a 250-watt rating. In this case, the solar panel output will be:

Daily watt hours = 5 × 250 × 0.85 = 1,062.5 kwh.

That means one solar panel with a 250-watt capacity can produce around 1,062.5 kwh, depending on its efficiency.

Factors affecting efficiency

It’s essential to be aware that certain factors can influence solar panel efficiency. Shading from nearby trees or buildings can cast shadows on your panels, reducing their output. Similarly, dust and debris accumulated on the panels can obstruct sunlight absorption. Regular maintenance and ensuring your panels have clear access to sunlight will ensure maximum efficiency and longer-lasting clean energy production.

How much can I save when placing solar panels on my garage?

The cost of installing solar panels can rely on several factors, including the number of panels, the complexity of the installation, and the type of panels. On average, in the UK, the cost of a solar panel installation for a garage roof ranges from £3,500 to £7,000.

But don’t let the initial investment deter you-this is where the magic of savings comes into play. Imagine making a small financial commitment upfront for a lifetime of returns.

With solar panels, you’ll not only reduce your dependence on traditional electricity sources, but you’ll also witness a remarkable drop in your electricity bills.

To calculate the savings, we need to follow these steps:

1. Calculate the energy produced by the solar array per year. Solar array production = 1,062.5 kWh/year
2. Determine the cost of electricity per kWh. You need to provide the cost per kWh from your utility company. Let’s assume the cost is  £0.12 per kWh.
3. Calculate potential savings. Potential savings = Solar array production × cost of electricity per kWh

Potential savings = 1,062.5 kWh/year ×  £0.12/kWh

Potential savings =  £127.50/year

So, based on the provided information and assuming a cost of  £0.12 per kWh from your utility company, your potential savings from the solar array would be approximately £127.50 per year. Remember that this is an estimation, and actual savings can vary due to factors like energy consumption patterns, weather conditions, and any variations in electricity prices.

How much electricity can solar panels on a garage roof produce?

The electricity production of your solar panels depends on several factors, including their capacity, orientation, and the amount of sunlight they receive. On average, a standard solar panel in the UK can produce around 250 to 400 watts of electricity.

Now, imagine a roof with multiple solar panels, each one diligently working to convert sunlight into energy. However, you might wonder when you can expect to see a return on your investment. The good news is that your garage solar panels have an average payback period of around 7 to 10 years. From that point on, you’ll enjoy nearly free electricity, as the energy your panels produce will offset the initial costs of installation.

Now that you know how solar panels can save money and benefit the environment, it’s time to take action. Don’t let the complexities of finding the right installer and comparing prices hold you back.

Garage solar panels: The pros and cons

Like any significant decision, there are both solar panel advantages and disadvantages to consider. Let’s explore more on the pros and cons of installing solar panels on your garage roof so that you can make an informed and rewarding choice for your home.

Advantages of garage solar panels

Utilising a flat surface

One of the greatest advantages of a garage roof is its flat surface, providing the perfect canvas for solar panel installation. A flat roof allows for easier and more efficient mounting. Flat roof solar panels maximise their exposure to sunlight throughout the day. Just envision the sun’s rays gently cascading over your garage roof, empowering the solar panels to convert sunlight into clean, renewable energy.

Abundant space

Your garage roof offers a generous amount of room for solar panels. You can install multiple panels with ample space, significantly increasing your electricity generation potential.

Financial savings

The most satisfying advantage of garage solar panels is the remarkable savings they bring. By generating your own electricity, you can substantially reduce your energy bills. On average, garage owners with solar panels can save up to  £127.50/year on their electricity costs from our calculation above with 400 watts of solar panels generation. This financial relief not only eases your budget but also provides a sense of empowerment and control over your energy consumption.

Disadvantages of garage solar panels

Initial investment

One of the main disadvantages of installing solar panels on your garage roof is the initial investment required. While solar technology has become more affordable in recent years, the upfront costs can still be significant. However, it’s crucial to remember that this investment pays off over time through energy savings and potential government incentives.

As you contemplate the initial cost, envision the long-term benefits that await you. With each passing year, your solar panels will continue to generate electricity, gradually offsetting the initial expenses and eventually leading to virtually free electricity for your home.

Are garage solar panels worth the investment

Yes! The advantages of garage solar panels far outweigh the initial costs, and the emotional and financial benefits make it an investment you won’t regret. Beyond the emotional rewards, garage solar panels offer substantial financial benefits. You’ll significantly reduce your dependence on traditional grid electricity by generating your own electricity. On average, garage owners with solar panels can save up to £127.50 per year on their electricity bills.

Just think about the financial relief and peace of mind that comes with knowing you have more control over your energy costs. However, making an informed decision about the cost of solar panels requires careful consideration of various factors, such as your energy needs, available space on your garage roof, and the expertise of the installation company.
