How are solar panels made?
To make use of silicon in the generation of solar energy, it first has to go through a purifying process. At this stage the silicon is in the form of sand or silicon dioxide, usually made from crushed quartz rock. After the silicon is purified it is then melted in a crucible to form an ingot. The ingot looks like a metal block at this point.
Using Sand to Store Solar Energy
Klingel plans to include a 2-ft. thick bed of sand between his concrete slab and a layer of rigid insulation. The sand is a heat sink, but Klingel isn't sure where the PEX tubing should be located for the best result. Nor is he sure what diameter the tubing should be, or what the spacing of tubing in the sand will work best.
