Solar Electricity Technical Guide

Solar Electricity Technical Guide: A Comprehensive Resource for UK Property Compliance

As the UK accelerates its transition to a low-carbon economy, solar electricity has emerged as a cornerstone of sustainable property management. For landlords, property managers, agents, and businesses, understanding the technical aspects of solar electricity is essential—not only for environmental stewardship but also for regulatory compliance, risk reduction, and long-term cost savings. This in-depth guide, tailored for Eco Approach Ltd clients and the wider UK property sector, demystifies the technicalities of solar electricity and provides actionable insights for integrating solar power into your compliance strategy.

What is Solar Electricity?

Solar electricity refers to the generation of electrical power using photovoltaic (PV) cells, which convert sunlight directly into electricity. Unlike solar thermal systems (which heat water), solar PV systems generate usable electricity that can power appliances, lighting, and even feed surplus energy back into the grid.

Key Components of a Solar PV System

Understanding the technical makeup of a solar PV system is crucial for safe and compliant installation and operation:

1. Solar Panels (PV Modules)
– Function: Capture sunlight and convert it into direct current (DC) electricity.
– Types: Monocrystalline, polycrystalline, and thin-film panels, each with unique efficiency and cost profiles.

2. Inverter
– Function: Converts DC electricity from the panels into alternating current (AC), which is compatible with the UK grid and standard appliances.
– Types: String inverters, microinverters, and hybrid inverters (for systems with battery storage).

3. Mounting System
– Function: Securely attaches panels to rooftops or ground frames, ensuring optimal orientation and tilt for maximum sunlight exposure.

4. Battery Storage (Optional)
– Function: Stores excess electricity generated during the day for use at night or during peak demand periods.
– Benefits: Increases self-consumption, resilience, and cost savings.

5. Monitoring System
– Function: Tracks system performance, energy generation, and faults, aiding in maintenance and compliance reporting.

Solar PV System Design Considerations

Proper design and installation are critical for both safety and performance. Key factors include:

1. Site Assessment
– Shading: Trees, chimneys, or neighbouring buildings can significantly reduce output.
– Roof Orientation & Tilt: South-facing roofs at a 30–40° angle are ideal in the UK.
– Structural Integrity: Roofs must support the additional weight of panels and mounting systems.

2. System Sizing
– Energy Demand: Assess the building’s electricity usage to size the system appropriately.
– Available Space: The number of panels is limited by roof area and shading constraints.
– Export vs. Self-Consumption: Decide whether to maximise self-use or export surplus to the grid.

3. Electrical Integration
– Grid Connection: Most systems are grid-tied, requiring approval and notification to the Distribution Network Operator (DNO).
– Safety Devices: Incorporate isolators, surge protection, and circuit breakers in line with BS 7671 (IET Wiring Regulations).

Compliance and Safety: Solar PV in the UK Regulatory Context

1. Building Regulations
– Part L: Solar PV installations can help meet energy efficiency requirements for new and existing buildings.
– Structural Safety: Ensure compliance with roof load limits and fire safety standards.

2. Electrical Safety
– BS 7671 Compliance: All electrical work, including solar PV, must comply with the latest edition of the IET Wiring Regulations.
– Competent Person Scheme: Installations must be carried out by registered, qualified engineers (such as NICEIC or NAPIT approved).

3. Planning Permission
– Most domestic solar PV installations are considered ‘permitted development’, but exceptions exist for listed buildings, conservation areas, or large-scale arrays.

4. Grid Connection and Export
– G98/G99 Applications: All grid-tied systems must be registered with the DNO under the relevant Engineering Recommendation (G98 for small systems, G99 for larger).
– Smart Export Guarantee (SEG): Enables property owners to earn payments for exporting surplus electricity to the grid.

5. Ongoing Maintenance and Inspection
– Annual Inspections: Recommended to ensure continued safety, performance, and compliance.
– Fire Risk Assessments: Solar PV systems should be included in property fire safety reviews, especially for commercial and multi-occupancy buildings.

Benefits of Solar Electricity for UK Property Managers

1. Reduced Energy Costs
– Generate free electricity, reducing reliance on grid power and exposure to price volatility.

2. Improved EPC Ratings
– Solar PV installations can significantly enhance a property’s Energy Performance Certificate (EPC) rating, supporting compliance with Minimum Energy Efficiency Standards (MEES).

3. Compliance with Net Zero Targets
– Landlords and businesses are under increasing pressure to decarbonise. Solar PV is a proven, visible step towards meeting sustainability commitments.

4. Enhanced Property Value and Marketability
– Properties with renewable energy installations attract eco-conscious tenants and buyers, often commanding higher rents and sale prices.

Common Technical Challenges and Solutions

1. Shading and Suboptimal Orientation
– Solution: Use microinverters or power optimisers to mitigate shading losses; consider alternative locations such as garages or ground mounts.

2. Roof Condition and Load
– Solution: Conduct a structural survey before installation; reinforce or repair roofs as needed.

3. Electrical Compatibility
– Solution: Work with accredited installers who understand local grid requirements and can future-proof systems for battery or EV charger integration.

4. Ongoing Maintenance
– Solution: Schedule regular inspections and cleaning; monitor system performance remotely to detect issues early.
