I mean when light hits the solar panel where does the energy go and what does it become? Be specific.
Visible light from the sun is in the form of photon before hitting the solar panel. In a silicon solar panel, the photon is caught by the semiconductor material. Energy equivalent of the photon is then used to excite an electron from the semiconductor molecule. The aggregate of free flowing electrons form the current in a closed electric circuit. The efficency of conversion from sun light to electricity is not 00%. The majority of light energy hitting the solar panel is dissipated in the form of heat. As technology advances, the conversion efficiency is improving, hence reducing the cost of solar energy.
image voltaic panels take the ability from the sunlight's easy this is extra extreme than say a easy bulb and utilising the chemical homes of (i think that's a silicon and carbon based fabric) the fabric to rework the easy(yet no longer warmth) into electric powered ability. it could basically use very particular wavelengths this is why image voltaic cells are nowhere close to useful. oo i forgot the 2nd area that's maximum suitable to place nevertheless status cells to the place they are going to receive easy the final public of the day (distinctly the early afternoon) and that's as direct as achievable. so some distance as business form cells they are fastened on structures which turn them by way of fact the sunlight strikes around the sky so as that they receive the main direct achievable easy
I think you got half the answer, but basically like everyone else said, the light hits the electrons and create energy now that energy, since it is now an electrical energy is then saved within batteries connected to the solar panel and that provides the power itself, so as long as there is sun, the batteries will charge up, once the sun goes away, the batteries slowly deplete, but once the sun hits, more energy. =)
Energy is conserved, meaning that no energy is lost. It has to go somewhere. So for solar panels, the main energy is electricity. The current that is produced by all of those silicon wafers is usually stored in DC batteries. Some of the energy from the sun is transferred into heat. Perhaps a Mechanical Engineer can better answer if any very minute expansion occurs from the sun. I would guess negligible.
In a photo-voltaic cell, the energy of the light knocks electrons loose within a semiconductor, causing electrical current to flow. see science.nasa /science-news/sci... Some other kinds of solar energy plants use lots of mirrors to focus sunlight and boil water to drive a steam turbine and generate electricity.
