Are Solar Panels Improving
Are Solar Panels Improving? A 2024 Guide for UK Landlords, Property Managers, and Businesses
As the UK continues its journey towards net zero, the built environment is under increasing pressure to improve energy efficiency and sustainability. Solar panels—once a niche technology—have now become a mainstream solution for reducing carbon emissions and lowering energy costs. But are solar panels really improving, and what does this mean for landlords, property managers, and businesses navigating compliance and sustainability requirements?
At Eco Approach Ltd, we support clients across the UK with property compliance, safety, and energy performance. In this article, we’ll explore the latest advancements in solar panel technology, their impact on compliance and property management, and why now is an excellent time to consider solar as part of your sustainability strategy.
The Evolution of Solar Panel Technology
Early Days: Limitations and Barriers
A decade ago, solar panels were often criticised for their high upfront costs, relatively low efficiency, and aesthetic impact on buildings. Many landlords and property managers hesitated to invest, unsure if the technology would deliver sufficient returns or compliance benefits.
Significant Improvements in the 2020s
Fast forward to 2024, and the landscape has changed dramatically:
– Efficiency Gains: Modern solar panels are now commonly achieving conversion efficiencies of 20-23%, compared to 14-16% a decade ago. This means more electricity generated per square metre, making installations viable even on smaller or shaded roofs.
– Cost Reductions: The average cost of solar panels has fallen by over 80% since 2010, thanks to economies of scale, improved manufacturing, and government incentives.
– Aesthetic Integration: Newer designs, such as solar roof tiles and integrated panels, offer a more discreet appearance—important for listed buildings or properties in conservation areas.
– Durability and Lifespan: Warranties of 25 years or more are now standard, with panels expected to last 30 years or longer with minimal performance degradation.
– Smart Technology: Integration with battery storage, smart meters, and building management systems allows for better energy optimisation and reporting.
Why Are Solar Panels Improving?
Several factors are driving the rapid improvement of solar panel technology:
1. Research and Development
Global investment in R&D has led to breakthroughs in materials science, such as the use of perovskite and bifacial panels that capture sunlight from both sides. These innovations are pushing efficiency and reliability to new heights.
2. Government Policy and Regulation
The UK government’s commitment to net zero by 2050, alongside updates to Part L of the Building Regulations and the Minimum Energy Efficiency Standards (MEES), has spurred demand for energy-efficient technologies. This, in turn, incentivises manufacturers to innovate.
3. Incentives and Funding
Schemes such as the Smart Export Guarantee (SEG) and various local grants make solar installations more financially attractive for property owners and businesses.
Solar Panels and Property Compliance: What’s New?
Energy Performance Certificates (EPCs)
Solar panels can significantly improve a property’s EPC rating—a key consideration for landlords and property managers, as the MEES currently require a minimum EPC rating of ‘E’ for rented properties in England and Wales, with proposals to raise this to ‘C’ by 2028.
Building Regulations
Updated Building Regulations (Part L) require new builds and major renovations to meet higher standards of energy efficiency. Solar panels are an effective way to achieve compliance, particularly for commercial and multi-residential properties.
Fire Safety and Electrical Compliance
Modern solar installations must comply with rigorous electrical safety standards, including regular EICR (Electrical Installation Condition Report) testing. Advances in panel design, mounting systems, and inverters have improved fire safety and reduced the risk of electrical faults.
Benefits of Improved Solar Panels for Landlords and Property Managers
1. Reduced Operating Costs
With higher efficiency and lower costs, solar panels offer faster payback periods and greater savings on energy bills. For multi-property portfolios, these savings can be substantial.
2. Simplified Compliance
Solar panels can help properties meet or exceed current and future energy efficiency requirements, reducing the risk of non-compliance penalties and void periods.
3. Enhanced Property Value and Marketability
Properties with solar installations often command higher rents and sale prices, as tenants and buyers increasingly prioritise sustainability and lower running costs.
4. Future-Proofing Assets
As regulations tighten and energy prices rise, investing in solar now helps safeguard your portfolio against future compliance risks and market shifts.
Common Questions About Solar Panels in 2024
Are Solar Panels Suitable for Older Buildings?
Yes. Modern, lightweight panels and integrated systems can be installed on most roof types, including older or listed buildings—subject to planning and conservation constraints.
How Do Solar Panels Affect EPC Ratings?
Solar panels directly improve EPC ratings by reducing a property’s reliance on grid electricity and lowering carbon emissions. This is particularly valuable for properties at risk of falling below the MEES threshold.
What About Maintenance and Safety?
Newer panels require minimal maintenance—typically an annual inspection and cleaning. Advances in safety features, such as rapid shutdown technology, have further reduced risks.
Is Battery Storage Worth Considering?
Battery storage has become more affordable and efficient, allowing properties to store excess solar energy for use during peak times or power cuts. This maximises self-consumption and savings.
