How Do Solar Panels Work?


How Do Solar Panels Work InThe UK?: A Guide

To make the most of solar photovoltaic (PV) technology in the UK, it's crucial to understand its core components and processes. Solar PV systems harness sunlight to generate clean, renewable energy. This starts with solar panels, which capture sunlight and convert it into electricity using the photovoltaic effect. An essential component, the inverter, ensures the electricity produced is compatible with your home or business. With the FIT scheme and net metering, you can even earn rewards for excess energy you contribute to the grid. Solar PV systems are grid-connected, providing continuous power. Their environmental benefits, low impact, and economic advantages make them a sustainable choice for a greener future.

Sunlight to Electricity: The Photovoltaic Effect

  • Solar PV systems in the UK are solar-powered marvels. They capture sunlight and convert it into electricity through the fascinating photovoltaic effect.
  • This remarkable phenomenon occurs when photons from sunlight strike the surface of solar panels, effectively freeing electrons from their atomic bonds.
  • These liberated electrons create a flow of electricity as they move through the panel's semiconductor material.


The Core Component: Solar Panels

  • At the heart of every solar PV system lies the solar panel, also known as solar modules or photovoltaic cells.
  • Solar panels come in various sizes and efficiencies, offering flexibility tailored to specific energy requirements and available installation space, find out more by contacting a member of our team.

Inverter: Transforming DC to AC

  • After generating direct current (DC) electricity, solar panels need an essential intermediary to convert it into alternating current (AC) electricity suitable for homes and businesses.
  • This critical role is fulfilled by the inverter, a crucial component of any solar PV system.
  • Inverters ensure that the electricity produced is seamlessly integrated with the grid and compatible with your appliances.

Net Metering and the FIT Scheme

  • One of the remarkable features of solar PV systems in the UK is the concept of net metering, including the SEG (Smart-Export Garuntee).
  • Under these initiatives, homeowners and businesses receive compensation for the surplus electricity they generate and feed back into the grid.
  • This not only promotes the production of excess clean energy but also makes solar PV systems both environmentally friendly and financially rewarding.

Grid Connection for Uninterrupted Power

  • Solar PV systems in the UK are predominantly grid-connected, ensuring a continuous and reliable power supply.
  • This means the electricity generated by solar panels can be used on-site, with any surplus power exported to the grid.
  • During periods of low sunlight or night-time, power can be drawn from the grid as needed, ensuring uninterrupted energy supply.

Environmental Impact and Sustainability

  • A primary reason for the surging popularity of solar PV in the UK is its significant environmental benefits.
  • Solar energy is a clean and renewable power source, effectively reducing greenhouse gas emissions, lessening reliance on fossil fuels, and contributing to the fight against climate change.
  • Moreover, solar PV systems have a notably low environmental impact, especially when compared to traditional energy sources.

Conclusion - Pioneering a Sustainable Future

Solar photovoltaic technology in the UK represents a sustainable and economically viable method of tapping into the sun's power to generate clean electricity. By aligning the right combination of solar panels, inverters, and grid connectivity, homeowners and businesses can savor the advantages of reduced energy costs, diminished carbon emissions, and even potential income through net metering schemes. As the UK vigorously pursues a greener and more sustainable future, solar PV undoubtedly takes centre stage in achieving these noble goals.
