Hi @zachsmail2925
Be aware that your Tempest solar sensor does not face the sun. It is a horizontal flat surface. To measure the ‘actual’ solar energy the Tempest sensor should be perpendicular to the sun. That would only occur if the sun is directly overhead. It means trying to match solar panel generation to the solar W/m2 measured from the Tempest requires some trigonometry which changes every moment or by mounting your Tempest at the same angle as your solar panels.
Searching on ‘solar’ returns this thread where I mention the issue.
cheers Ian
