Amorphous silicone panels are the most advanced technology of the three. Unfortunately they are not as stable or efficient for mass useage. They require much more surface area to be productive. In view of this I have chosen not to discuss them here. Their advantage is that they do not become less efficient at high temperatures ie above 50 degrees C as the other two do.
Mono crystalline silicone panels are a slice from single crystal. This gives the cell the unusual diamond type shape. They are sliced wafer thin.
Multi crystalline silicone panels, also known as poly crystalline solar panels, are made from slices of many cells that are fused together then sliced into cells. These are then cut and assembled to form a wafer. These can be made into whichever shape hence the more efficient appearing square shaped cells. These days, cells and panels are laser cut with advanced computer driven technologies. This gives a very accurate and clean slice.
In both mono crystalline and multi crystalline solar panels the crystal layer is very fine. The bulk of the panel is made up of the supporting structures including tempered glass, EVA film and rear film. Generally they have an aluminium frame. Ideally panels are attached to rooftops by a system of aluminium mounting system. Ideally this system will be around 100 millimetres above the roof surface. This allows for drainage and self cleaning of water and leaves. It also allows for cooling of the panels as they can generate a lot of heat.
Mono crystalline silicone solar panels are reported to be more efficient than the multi crystalline silicone solar panels. They are also reportedly more expensive to make. However, multi crystalline panels are a good affordable option to encourage more people to implement solar panels for their home energy needs.
There are also differences in wattage output dependent on quality of panel whether mono crystalline or multi crystalline. Both types of panel become less efficient when temperatures reach 50 degrees Celsius.
Solar portable panels as with any solar panel, require an inverter to change the energy gathered from the sun into useable household energy. When collected from the sun, the energy is DC meaning Direct Current. This is a higher current than household use electricity that comes out of the socket in the wall. The energy we get from the wall socket has been converted to AC which means alternating current.
Currently Germany is the world leader in solar energy. With current global warming and conscientiousness of renewable energies, more countries are exploring solar energy.
