Building solar panels of this type involves the skill of cutting tiny discs of crystalline silicon into pieces that are less than a centimeter thick. The discs that are wafer thin then go through the delicate process of repairing and polishing any damage caused by the slicing effect of the discs.
Once polishing has been completed the wafer thin disc has 'dopants' and metal conductors are added and spread across each solar cell. This is the process of materials added to alter the electrical charge in the semi conductor or photovoltaic of the solar cell itself.
The conductors are then placed face down lying flat and facing the earth on a thin sheet in a matrix grid like arrangement on top of the solar panel.
You then place a thin sheet of glass over the top of the cells and bonded this process is for the protection of the solar panel. After completing the bonding process you will then attach the panel to a substrate using and expensive thermally conductive cement, panel is almost complete at this stage. The thermally conductive properties of the cement will protect the panel from over excessive heat that can damage the solar panel. Excessive heat from the sun that the panel can not use or convert is dispersed and removed from damaging the solar panel. This will help a great deal the efficiency of the solar panel by keeping it in top working condition.
There is one more important factor to consider in avoiding the solar panel from over heating damage. When you are ready to install the solar panel keep it off the ground and have the air flow able to move freely around the panel. This might sound strange considering that solar panels require the sun to operate efficiently. But the point is they require the rays from the sun to operate not the heat. Even Roof panels have slight elevation from the roof tiles when installed so airflow can move freely between them.
Make the panels once and make them last is the best policy one can apply when engaging in solar power projects. When you embark on a project to convert your home to solar think long term and plan thoroughly to get the best results.
