We believe everyone should be able to understand the codes and variables that affect the structural and foundation design of all solar pole mounts regardless of brand or design. Some manufacturers are depending on wind speed sensors to flatten the array out when the wind blows to make the structure and foundation cheaper and lighter. Over the years, we have seen the majority of tracking systems malfunction at one time or another and we are not willing to depend on a small plastic wind speed indicator and a low powered adjustment system to prevent the foundation or structure from failing in a strong wind! Feel free to download or make a copy of the spreadsheet below for your personal use and to better understand the loads that affect all solar systems. We are releasing this in the spirit of open source software, please play fair and do not re-distribute or make changes without permission! If you have any questions please contact me!
