Another popular tool is the solar inverter supplier. This instrument is rather user friendly, but is much more expensive than the Solar Pathfinder. This will set you back by at least $1,500...yet there is a cheaper option.

Why Do We Need To Use A Solar Pathfinder?

A proper instrument like a Solar Pathfinder can save you lots of time and guesswork. Moreover it is easy to use and is reasonably affordable.

 

If we do not use any instrument to determine shadow positions, we'll need to observe their movement from dawn to dusk -- this is certainly not an efficient use of time. This is a waste of time! Moreover, these solar battery positions shift (slightly) through different seasons because of how the earth rotates around the sun.
