How Does Solar Energy Work

How Does Solar Energy Work? A Comprehensive Guide for UK Property Owners

As the UK moves towards a greener, more sustainable future, solar energy is at the forefront of the renewable revolution. Solar panels are becoming an increasingly common sight on homes, commercial buildings, and even large-scale developments. But how does solar energy actually work? And what should landlords, property managers, and businesses in the UK know about integrating solar power into their properties?

At Eco Approach Ltd, we specialise in keeping properties compliant, safe, and energy-efficient. In this article, we’ll explain how solar energy works, the benefits it offers, and what you need to consider if you’re thinking about solar for your property portfolio.

What is Solar Energy?

Solar energy is energy harnessed from the sun’s rays. The sun emits vast amounts of energy every second, and with the right technology, we can capture and convert this energy into electricity or heat for use in homes and businesses.

There are two main types of solar technology:
– Photovoltaic (PV) systems: These convert sunlight directly into electricity.
– Solar thermal systems: These use sunlight to heat water or air for heating purposes.

For most UK property owners, solar PV panels are the most common and accessible form of solar energy.

How Do Solar Panels Work?

Solar panels work by converting sunlight into electricity through a process known as the photovoltaic effect. Here’s a step-by-step breakdown:

1. Sunlight Hits the Solar Panels
Solar panels are made up of many smaller units called solar cells, typically made from silicon. When sunlight (composed of photons) strikes the surface of these cells, it excites the electrons within the silicon.

2. Generation of Direct Current (DC) Electricity
The excited electrons move, creating a flow of electrical current. This is direct current (DC) electricity.

3. Conversion to Usable Power
Most homes and businesses use alternating current (AC) electricity. Therefore, the DC electricity generated by solar panels passes through an inverter, which converts it into AC electricity suitable for powering appliances and lighting.

4. Powering Your Property
The AC electricity is then fed into your property’s electrical system. You can use this energy to power your building, reducing the amount of electricity you need to buy from the grid.

5. Exporting Surplus Energy
If your solar panels generate more electricity than you use, the surplus can be exported back to the National Grid. Under the UK’s Smart Export Guarantee (SEG), you can be paid for this exported energy, providing an extra financial incentive.

Solar Energy in the UK: Is It Effective?

Despite the UK’s reputation for cloudy weather, solar energy is surprisingly effective. Modern solar panels can generate electricity even on overcast days, as they rely on daylight rather than direct sunlight. The key factors affecting solar performance include:

– Roof orientation and angle: South-facing roofs at a 30-40 degree angle are optimal.
– Shading: Trees, chimneys, or nearby buildings can reduce efficiency.
– System size: Larger systems generate more electricity but require more space.

On average, a typical UK solar PV system can generate between 2,500 and 4,000 kWh of electricity per year—enough to cover a significant portion of a household or small business’s needs.

Benefits of Solar Energy for UK Property Owners

1. Reduced Energy Bills
By generating your own electricity, you can significantly cut your reliance on grid-supplied power, leading to lower energy bills.

2. Income from Exporting Surplus
Through the Smart Export Guarantee, you can earn money for excess electricity your system exports to the grid.

3. Lower Carbon Footprint
Solar energy is clean and renewable, helping you reduce your property’s carbon emissions and contribute to the UK’s net-zero targets.

4. Improved EPC Ratings
Installing solar panels can improve your property’s Energy Performance Certificate (EPC) rating, which is increasingly important for landlords and property managers in meeting minimum energy efficiency standards.

5. Futureproofing Against Regulation
As the UK government tightens energy efficiency regulations, properties with renewable energy systems will be better positioned to comply with future requirements.

What to Consider Before Installing Solar Panels

1. Roof Suitability
A structural assessment is essential to ensure your roof can support the weight of solar panels. At Eco Approach Ltd, we can coordinate qualified assessors to evaluate your property’s suitability.

2. Planning Permission
Most domestic solar installations are considered ‘permitted development’ and don’t require planning permission. However, exceptions apply for listed buildings, conservation areas, or commercial properties.

3. Electrical Compliance
Solar PV systems must comply with UK electrical standards (such as BS 7671). Proper installation and regular inspection are vital for safety and compliance. Eco Approach can manage your electrical compliance needs alongside your solar installation.

4. Integration with Other Systems
If your property has other energy systems (e.g., heat pumps, EV charging points), careful integration is required to maximise efficiency and compliance.

5. Ongoing Maintenance and Certification
Solar panels require minimal maintenance, but periodic inspections ensure optimal performance and safety. Keeping documentation up to date is crucial for compliance and resale value.

Solar Energy and Regulatory Compliance

For landlords, property managers, and businesses, solar energy isn’t just about sustainability—it’s about compliance. Here’s how solar fits into the UK’s regulatory landscape:

– Energy Performance Certificates (EPCs): Solar panels can improve EPC ratings, helping properties meet the Minimum Energy Efficiency Standards (MEES).
– Electrical Safety: Solar installations must be tested and certified to ensure they’re safe and compliant with UK regulations.
– Fire Safety: Proper installation and maintenance reduce fire risk, and regular fire risk assessments should include any renewable energy systems.

Eco Approach Ltd provides a single point of contact for all your compliance needs, from electrical safety checks to EPC assessments and fire risk evaluations. We coordinate qualified engineers nationwide to deliver consistent, compliant results at scale.

The Future of Solar in the UK

Solar energy is set to play a pivotal role in the UK’s transition to a low-carbon economy. With rising energy costs and increasing regulatory pressure to improve energy efficiency, now is the ideal time for property owners to consider solar.

At Eco Approach Ltd, we help landlords, agents, and businesses navigate the complexities of property compliance, including the integration of renewable energy systems. Our services are designed to simplify regulatory compliance, reduce risk, and ensure your properties meet current and future UK legislation.

Conclusion

Solar energy works by converting the sun’s rays into electricity through photovoltaic panels. It’s a proven, effective way for UK property owners to cut energy costs, reduce carbon emissions, and futureproof their assets against tightening regulations.
