The silver surface is there to reflect the heat back on to the solar panel. thats if any heat has gone through the solar panel
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.
Absolutely! In fact, there are many light/solar-powered calculators already out there. If you look at a basic calculator, there's usually a black strip near the top corner. That's the solar panel. If you cover it up, you'll notice that the calculator usually shuts off but quickly comes back on when you uncover it.
A mirror would be the most effective object for light reflection. Typically mirrors are "Silvered" using either silver or aluminum on the back and the light passes through glass to the silver and bounces back. However, astronomical mirrors have the mirrored surface on the front which will reduce distortion
At the earth's surface about 51% of incoming solar radiation is absorbed, and 4% is reflected back into space.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
Solar Collectors use the greenhouse effect to capture the sun's energy. It is able to harvest the suns energy in the form of heat. Greenhouses use air to transfer heat and Collectors use water or a combination of water and antifreeze. Solar Panels (or solar panel kits) are very much different.. They convert solar radiation into electricity and they work best in direct sunlight at a low temperature. Large PV (Photo Voltaic) systems are still quite costly. They produce DC current and require inverters to convert the DC to compatible AC power. The AC power is often connected to the grid so that solar energy may be sold back to the power company. Due to the reimbursement tariffs it makes sense to feed all the solar power into the public grid and continue consuming household electricity at much lower rates.
Not 100% sure here but i believe it is to reflect the sun back towards the panel to double the efficiency by making use of both sides of the panel.
becuase a robot came on it

On the back side of the solar panel. Its 5.1 wats, 17.5 V, and 290ma, manufactured in ap;ril of 2002
You need a little solar panel which you can buy from a hobby shop or online. I bought a little mechanical grasshopper with a solar panel on its back. In the sun something eccentric rotates, making the grasshopper vibrate and move across a table.
Most of it is reflected back into space.

Sunspots do not explode, sunspots are cooler regions of the Sun's surface caused by what are basically magnetic field "tangles" stopping the convection that brings heat to the solar surface. When the "tangle" untangles or snaps back the Sunspot fades away as that bit of the surface heats back up. For explosions on the surface of the Sun, try looking up solar flares or corona.
Solar panels are comprised of several layers of materials which combine to become a solar panel. Starting with the solar cells which are arranged in a specific size per application on a sheet, covered with a tempered glass, and then wrapped in an aluminum frame to protect its sidewalls from damage. At the back, a junction box is installed so the panels can be wired into an array. Head to the Soligent website and there's tons of resources.

About 6% of incoming solar radiation is reflected back into space from the atmosphere and 4% by the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
