We often hear the question 'What are Solar Panels'. Well, the answer in its simplest form is... A solar panel is a device that uses the suns energy and transforms it into something usable in the form of electricity (Solar Photovoltaic) or heat (Solar Thermal).  

Many people do not realise that there are two types of solar panels, because why would they? They both look exactly the same, however they both do completely different things.

Solar Thermal uses the suns energy to generate hot water only, not electricity. 

Solar Photovoltaic (PV) when exposed to direct sun light converts it into electricity. The solar PV panels are made up of photovoltaic cells, this is where the term Solar PV comes from, these cells turn sun light into electricity.

Solar panels, also known as Solar photovoltaic (PV) panels, are devices that convert sunlight directly into electrical energy. They are a key component of solar power systems used to generate electricity from renewable energy sources.

Solar PV panels is a system which harnesses the suns energy and converts it to usable clean energy using two main components; The solar panel which is the device that captures the sunlight and the the PV cells within it which converts the it into electricity. 


PV cells are made of materials that generate electrons when exposed to the sunlight light. The electrons flow through a circuit and produce direct current electricity, which can be used to power various devices or if you have excess energy it can sold back to the grid or be stored in batteries.

Solar PV panels are installed and widely in domestically in homes and commercially in businesses across the UK. They are a vital piece of technology which play an essential part in the transition to a cleaner and greener energy source.
