Different Types of Solar Energy
Usually, the sun is the main power source for the solar energy we use. Solar energy refers to the ways light can be gathered and then changed into energy. We have heating energy such as ‘solar thermal’ and ‘solar power’ and ‘photovoltaic’ (PV) used for electricity. We also have ‘passive solar gain’, which is where natural light comes through our windows and helps to heat the inside of our homes. There are ways to improve this, such as more windows (bigger ones facing the south) and thermal materials that keep in heat. You need to be careful that the extra glass doesn’t cause too much heat in the summer, so you need to think of how to keep the house cool during this time. You could use a ‘brise-soleil’ to give shade when it’s hot, which can still let light in. If a passive solar design is developed properly, it can potentially give 40% of heat to a building.
Solar thermal panels use a black material that takes in light, heats and then moves it as a fluid into where it’s needed such as a home or swimming pool. The more insulation it has, the less sun it actually needs, so it can still work in cloudy weather.
PV changes light straight into electricity. Thin silicon ‘wafer’ materials are used in a PV panel. A solar inverter changes ‘direct current’ (DC) into ‘alternating current’ (AC). This means the energy can be transferred to the grid and used somewhere else, which provides a bigger advantage.

Solar Power: Energy Efficiency And Cutting Down Your Carbon Footprint
The UK can sometimes have dull and dingy weather, but luckily solar panels can still work when it’s cloudy. The electricity created won’t be as strong, but energy can still be captured. You will get the best result if they are fitted on to a suitable roof that is facing south, although east and west is acceptable.
A solar panel needs to be angled between 10 to 50 degrees. The best angle should be between 30 and 40. Trees and buildings shouldn’t be near by, as these can affect the panels by producing shade. Solar panels are usually fitted on to a roof, but they can be fitted on the ground or walls.
The biggest advantage is energy and financial efficiency. The larger your solar panels, the more electricity will be created. There could be enough to power your whole house, which will benefit your energy bills!
Your carbon footprint will also be lowered. Depending on which area you live in the UK, a standard home PV (photovoltaics) system can save between 1.3-1.6 tonnes of carbon each year, greatly helping the environment!
Your energy supply shouldn’t be affected by solar power. If the panels don’t create enough electricity, it should transfer smoothly to using the National Grid.
Overall solar panels may cost a bit to fit initially, as it depends on the size you need for your roof, but on the long run you will save on energy bills and help the environment. To learn more about Solar panels in Exeter call us today.
