Frost in the ground of your solar array can cause both frost heaving and adfreezing which causes irreparable damage to your solar racking foundation. While there is no way to prevent soil from freezing and melting, performing a cold weather-focused geotechnical and pile testing program can help you choose the correct foundation type and installation method. With the right foundation, frost heaving and/or adfreezing will not have any impact on your solar array.
