How do Solar Energy Panels Work?
Photovoltaic Solar Panels are by far the most common harness of solar energy. They are durable, long lasting, have no moving parts and can be built to withstand the elements.
Most Solar panels are made of crystalline silicon. The wafers of crystalline silicon are actually brittle, but are hard cased in an electrically insulated panel to protect them from damage and shorting out.
The panels are connected in series if you want to increase the amount of voltage supplied, then in parallel to increase it's current.
Manufacturing production of Photovoltaic solar panels has increased dramatically in recent years due to the growing demand for clean sources of energy, doubling about every two years.
So how do these solar panels work? Put simply, they take photons from the sunlight to knock the electrons into a higher state of energy.
DC current is produced as a result, enabling it to charge a battery or run any device designed to operate on DC current.
To convert DC current to household AC electricity, an inverter is required. The expense of inverters is declining as demand continues to increase.
A second kind of solar panel is the Amorphous silicon panels. Amorphous solar panels do not have a mosaic crystal structure, but are like glass. All of the silicon atoms are randomly placed rather than in an organized structure. The amorphous panels are cheaper because unlike Crystalline silicon panels, they don't require time to form.
Some manufacturers have produced solar panels
containing both amorphous and crystalline silicon for maximum
efficiency. The kind of panel you will want to build depends on the cost
efficiency of each option.
