Maximising solar panel efficiency
Most of the time, it is best to face your solar panels south. The right orientation of arrays can increase energy output up to 30% or even more. Some homeowners may consider other directions, including north.
How do you know the direction in which your solar panels will face? This article will help you determine the best direction to achieve your goals and what factors influence this decision. Even if solar panels facing south are not an option, there are other solutions. For Solar Panels Exeter, contact www.slelectricals.co.uk/solar-panels-exeter/
What is the importance of solar panel placement?
You may be wondering why the position of an array matters. As long as your solar panels are pointing towards the sun, you’ll get energy, right?
It’s only partially true. But if you understand how the equipment works, then you can produce even more energy. Solar panels must face the sun directly to maximise their efficiency.
Each panel contains several photovoltaic cells (units which absorb sunlight). The panels are made from a semiconductor that absorbs specific wavelengths of sunlight, known as a bandgap. Studies show that silicon cells are only able to absorb 33% of energy that is thrown at them.
The PV cells require direct sunlight because this band gap can be so selective about the waves it absorbs. These cells begin to reflect wavelengths instead of absorbing in the sunlight with even a slight turn away.
It’s well worth the investment to direct your solar panels in the right direction when they only receive a limited amount of energy. The right angle and this simple adjustment can significantly increase the efficiency of your solar array.
