Sand Battery Experement
The reason to use sand is because of its physical properties - it won''t change state until you reach 1700C. Sand absorbing and releasing Joules at a higher transfer rate is an advantage in a

To build solar panels, silica-rich sand must be extracted from natural deposits, such as sand mines or quarries, where the sand is often composed of quartz, a form of crystalline silica. The sand is washed to remove impurities like clay, organic matter, and other minerals. It is then refined with chemical processing methods.
Half power (1,200 watts) is probably still safe though. In most areas, you are lucky to get a solid 3 or 4 sun hours of energy out of the solar panels. Using 3.5 x 864 watts means you might put a bit over 3 kilowatt hours of energy into the sand.
Having the element buried in sand will pull some heat out, but it is then in an insulated casing, the temp could rise quite a bit higher than what it would do out in free air. Half power (1,200 watts) is probably still safe though. In most areas, you are lucky to get a solid 3 or 4 sun hours of energy out of the solar panels.
Ultimately, every solar cell begins its life as quartz sand. Also known as silica sand, quartz sand consists of at least 95% pure silicon dioxide, which is also known as silica or as SiO 2. But we don't need silica for solar cells, but silicon, which means we need to get rid of the oxygen, to leave behind pure silicon.
