If its a completed panel, it already has a cover on it.
if you are trying to protect your panel, you can cover it with whatever you think would protect it from whatever you think will hurt it. (hail, rain, etc.)
A solar panel is used to save energy when the sun shines on it
Batteries are not used in solar panel construction
To make a working model of a solar panel, you will need solar cells, a backing material, wiring, and a transparent cover. Connect the solar cells in series so that they generate electricity when exposed to light. Place them on the backing material, wire them together, and cover with the transparent material to protect them. When exposed to light, the solar cells will generate electricity that can be used to power small devices or charge batteries.
You can buy used solar panels from ebay, the average cost for a solar panel is around forty six to seventy nine dollars for a used solar panel but you can probably find a cheaper one on the website.
A silver surface is used at the back of a solar panel to reflect sunlight that passes through the photovoltaic cell, allowing it to be absorbed and converted into electricity. This helps improve the efficiency of the solar panel by reducing energy losses.
A metal dish is used as the framework of a solar panel because the sun heats the metal, heating the water inside
Solar energy.
silicon and boron
two kinds of solar panel exist. if a solar thermal panel, for hot water or hot air, is not being used then any solar energy landing on it is not drawn away by the water or air. The panel temperature rises depending on the characteristics of the panel and the amount of sunshine. as the temperature rises the panel loses more and more heat back to the atmosphere so that the losses always equal the gains. energy absorbed = energy used (or stored) + energy lost.
solar panel ususally
A solar panel laptop would use a battery which would be charged by a solar panel. There are several brands available through a company named "Tree Hugger," there are also a number of other brands available.
A solar panel, which is comprised of photovoltaic cells arranged in series.
