In this resource, you’ll learn about the different types of solar panel installations and their respective financial performance. We’ll cover their energy efficiency, the costs of installation, the savings they can generate in the long term, and how long they will take to pay for themselves. By the end, you’ll have a solid understanding of what type of solar panel installation will give you the best return on your investment (ROI).
The Various Types of Solar Panel Systems
Before diving into the finances, let’s first understand the different types of solar panel systems available for you. They can be primarily divided into three types:

- Monocrystalline panels
- Polycrystalline panels
- Thin-film panels
Monocrystalline panels are made from single crystal structure. They are the most energy efficient and expensive among the three types.
Polycrystalline panels, on the other hand, are made from silicon fragments melted together. They are less efficient but also less expensive than monocrystalline panels.

Lastly, thin-film panels are made by placing one or more films of photovoltaic material (such as silicon, cadmium, or copper) onto a substrate. They are the least efficient and cheapest among the three types.
The Cost of Solar Panel Installation
Let’s now consider the costs of installing these solar panel systems. The cost of solar installation varies depending on the type and size of the system, and the complexity of the installation.
For the average UK homeowner, it costs between £6,000 and £7,000 to install a 4kW solar panel system on the roof. This is the typical size of a solar panel system for a family-sized home. However, the price can fluctuate depending on the type of panels chosen. Monocrystalline panels, being the most efficient, will cost more than their counterparts.
But remember that the initial cost of installation should not be your only consideration. Efficiency and longevity should also be considered as they contribute to the system’s overall ROI.
Solar Energy Efficiency and Savings
Now let’s talk about the efficiency of these systems. The more sunlight the solar panels can convert into electricity, the more efficient they are. Monocrystalline panels, for instance, have an efficiency rate of approximately 20%, while polycrystalline panels have a rate of around 15-17%. Thin-film panels, on the other hand, have an efficiency rate of between 10-12%.
Higher efficiency means more power production which directly translates to higher savings on your electricity bills. Moreover, the UK government’s Feed-in Tariff scheme (FIT) pays you for the electricity you generate, even if you use it, providing another source of savings.
Solar Panels ROI and Payback Period
Finally, let’s consider the return on investment and payback period. The ROI of your solar system is primarily determined by the amount of money you save on your electricity bills and the earnings from the FIT scheme.
The average UK homeowner would see a payback period of about 10 years for the system. That means after 10 years, the savings you’ve made on your electricity bill and the earnings from the FIT scheme will have completely paid for the system’s installation costs.
Remember, however, that while monocrystalline systems might have a higher upfront cost, they also have higher efficiency. This means they produce more power, leading to higher savings and potentially a shorter payback period.
In contrast, while thin-film panels have the shortest upfront costs, their lower efficiency results in smaller savings and a potentially longer payback period.
Conclusion
In conclusion, the type of solar panel installation that provides the best ROI for UK homeowners depends on several factors, such as the initial cost, energy efficiency, and the projected savings on electricity bills. While monocrystalline panels are more expensive upfront, their higher efficiency can lead to larger savings and a quicker payback period, making them a good investment for many homeowners.
Understanding the Solar Battery Storage System and its ROI
Now, another significantly important part of a solar system is the solar battery storage. This component stores the excess power produced by your panels during the day, allowing you to use solar-generated electricity even when your system isn’t actively generating power, such as at night or during periods of low sunlight.
Solar batteries can significantly boost the ROI of your solar installation in the long term by maximising the use of the electricity generated by your panels. Instead of sending excess power back to the grid, which the FIT scheme will pay you for, you can store it and use it later. This not only reduces your reliance on the grid but also means you’ll be drawing less electricity from your supplier, thereby further reducing your energy bills.
The cost of adding a solar battery to your solar panel system varies depending on the capacity of the battery. On average, a solar battery in the UK costs between £4,000 and £6,000.
The payback period for a solar battery depends on a variety of factors, including your household’s energy usage, the size of your solar panel system, and how much electricity you can store and use. Assuming you use a significant proportion of the stored energy, the average payback period for a solar battery is between 6 and 10 years.
Long term benefits of the Solar Power System
Investing in a solar panel system is a long term commitment that comes with a plethora of benefits. The highlights being a reduction in energy bills, contributing to a greener environment by reducing reliance on non-renewable energy sources, and the potential for a financial return through the government’s FIT scheme.
Once installed, a solar panel system can last for more than 25 years. During this period, the savings you make on your energy bills, combined with the earnings from the FIT scheme and potentially a solar battery, will likely offset the initial installation cost and provide a return on your investment.
Keep in mind that the amount of sunlight your solar panels receive directly impacts the system’s power output. Therefore, the geographical location and positioning of the panels on your property will affect the system’s productivity and ROI.
Conclusion
The question of which solar panel installation provides the best ROI for UK homeowners does not have a one-size-fits-all answer. It comes down to individual circumstances, such as your budget, energy consumption, and the suitability of your property for solar installation.
Monocrystalline panels, despite their higher upfront cost, tend to offer the best long-term ROI due to their higher efficiency and power output. However, a solar system’s ROI can be enhanced by incorporating a solar battery storage system, which allows homeowners to make the most of the power generated by their panels.
Investing in solar power, irrespective of the type of panel chosen, is a step towards a sustainable future, reduces reliance on grid electricity, and presents an opportunity for long-term savings. With the government’s FIT scheme as an additional incentive, solar power continues to be a viable and attractive option for UK homeowners.
