Investment & ROI for Solar PV Installation

Investing in solar PV can yield significant long-term savings making the cost of solar PV installation a sound investment for the future. Homeowners typically see a return on investment (ROI) within 5 to 10 years. For instance, a 5kW system costing around £7,500 can generate approximately 4,500 kWh annually, leading to potential savings of £850 on electricity bills and additional earnings through the Smart Export Guarantee (SEG).

Estimated Annual Savings:

  • Electricity Savings: £850
  • SEG Income: £243
  • Total Savings/Earnings: £1,093 per year
  • Payback Period: Approximately 7.5 years

 

Note: These calculations do not factor in the annual increase in electricity prices, which can substantially boost your savings over time. Additionally, the figures are based on averages and conservative estimates; individual properties may achieve a quicker return on investment.

Technical Considerations - Solar Panel Types

Monocrystalline panel - Cost of solar pv installation

Monocrystalline Panels

Monocrystalline panels feature a sleek, uniform dark finish and offer efficiency rates of up to 22%. They have a longevity of over 25 years, often with warranties extending to that same duration, and perform better in low-light conditions. While they come at a higher upfront cost, they are ideal for smaller roofs and offer a range of aesthetic options in various colors and finishes.

Polycrystalline Panel - Cost of solar pv installation

Polycrystalline Panels

In contrast, polycrystalline panels have a bluish hue with a speckled texture and efficiency rates between 15% and 20%. Their lifespan ranges from 20 to 25 years, with warranties typically between 10 to 25 years. These panels require more roof space to achieve equivalent output and are more affordable, making them suitable for larger installations. However, they have limited color options compared to monocrystalline panels.

Technical Considerations - Inverter Technologies

String inverter - Cost of solar pv installation

String Inverters

String inverters convert DC electricity from multiple panels connected in series. They are less efficient in partial shading and are typically mounted on a wall, such as in a garage or utility room, making them generally more cost-effective.

Micro inverter - Cost of solar pv installation

Microinverters

On the other hand, microinverters convert DC electricity from each panel independently, offering better performance in shading or varied sunlight conditions. They are attached directly to each solar panel, which results in a higher initial cost.

Technical Considerations - Optimisation Technology

Power Optimisers

Power optimisers are devices designed to maximise energy output by adjusting the voltage of solar panels. They enhance performance, particularly in shaded or irregular conditions, ensuring that each panel operates at its optimal level. Their compact design allows for easy mounting near the panels, making them an unobtrusive addition to the solar setup. Maintenance is minimal, though regular checks are advised to ensure everything is functioning properly. Overall, power optimisers offer significant benefits in terms of energy efficiency and system performance.

Technical Considerations - Battery Energy Storage Systems (BESS)

Battery Energy Storage Systems (BESS) are changing the way we manage energy in our homes. With many of us working from home, our energy consumption patterns have shifted, leading to increased usage during the day. While solar photovoltaic (PV) systems do a great job of capturing sunlight and generating energy, they often fall short during peak demand times—like in the morning when we’re making coffee or in the evening when we’re cooking and enjoying entertainment.

This is where BESS comes in. By storing excess energy generated during the sunny hours, these systems ensure that you have power available when you need it most. It’s an effective way to maximise your solar energy use and create a more resilient energy supply.

Understanding BESS Costs

Initial Investment

Often included in the cost of solar PV installation, the average cost of a BESS unit ranges from £3,000 to £8,000. This is an investment in enhancing your home’s energy efficiency and independence. Installation costs typically add another £1,000 to £2,000, which covers professional setup to ensure everything runs smoothly. The two most common types of BESS for domestic installs are:

Lithium-ion battery for solar - cost of solar pv installation

Lithium-Ion Batteries

These are the most popular choice for homeowners due to their high efficiency and longer lifespan. Prices generally range from £5,000 to £7,500 for systems that offer 5-10 kWh of storage.

lead-acid battery for solar - cost of solar PV installation

Lead-Acid Batteries

A more budget-friendly option, with costs between £3,000 and £5,000. While they are less efficient and have a shorter lifespan, they can still be a viable choice for some users.

The Role of Location in Solar Efficiency

Your solar PV system’s efficiency is influenced by your location. Areas with higher solar irradiance, such as southern England, can generate more electricity from the same number of panels, leading to a shorter payback period and a reduced burden on the cost of solar PV installation. However, even in regions with less optimal sunlight, solar PV systems are still valuable, providing significant savings over time.

Debunking the Myth: Solar PV is Useless in the UK

A common misconception is that solar PV systems are ineffective in the UK due to frequent cloudy weather. However, modern solar panels can still generate significant energy from diffused light.

  • Light Conversion: Solar panels convert both direct and diffuse sunlight, producing around 20-30% of their rated capacity on cloudy days.
  • Year-Round Output: Despite seasonal variations, many systems achieve substantial annual energy outputs, often meeting or exceeding expectations based on the UK’s average solar irradiance.
  • Efficiency Boosts: High-efficiency monocrystalline panels and optimisation technologies (like microinverters) can enhance performance, even in less sunny conditions.

Smart Export Guarantee

The Smart Export Guarantee (SEG) allows you to earn money by exporting excess energy back to the grid and offset the cost of solar PV installation. Considering typical on-site energy consumption, here’s a potential earnings breakdown based on system size, using an SEG price of 27p* per kWh:

System Size Estimated Annual Output (kWh) On-Site Consumption (80%) (kWh) Exported Energy (20%) (kWh) Estimated Earnings from SEG (at 27p/kWh)
3kW
2,700
2,160
540
£145.80
4kW
3,600
2,880
