The future of solar doesn't track the sun
PV modules are cheap enough today that the simple fixed East-West arrays are cheaper and faster to install than the industry’s darling, the single-axis tracked array. Xavier Dedenbach, Terraform Po…
Backtracking: deviating from the solar position to collect more sunlight, such as lying horizontally on cloudy days to capture ambient light or moving to avoid shading from one row to another during early mornings or late afternoons. Figure 25: Hail damage on PV modules https://info.nextracker.com/hubfs/Updated_Collateral/NX Horizon_Risk Mitigation Whitepaper_Part 1.pdf Texas may be especially at risk today, as it is located in Tornado Alley and has some of the worst hailstorms in the country, and due to its high solar density. There are instances of PV array operators reducing their insurance premiums by up to 72% through the construction of hail-resistant systems, single-axis tracked solutions with a validated hail-stow function, and higher impact-rated panels.
