It’s not working, the lamp is stay off.
and then it’s strange, it works on a certain angle but not others. for 20 degrees it works but for 15 degrees not for example, and then the lamps light up while the sun is at 45 degrees and not 20.
there is a mathematical contradiction, I indicated that the lamps must ignite when the angle of the sun is equal to 0. However, the lamps ignite at 45 degrees.
