After you’ve completed your Solar Installation or Upgrade, you’ll want to know if it works. And if it does, how well does it work. Guessing how much sunlight is in your area is a surprisingly flawed concept. With this meter you’ll be able to tell HOW MUCH sunlight is striking the device. Then compare that to the output of your panels. The real “fun” comes when you TIP or TILT the meter slightly and watch the dramatic changes in “power”. Already have a system? Then use this meter to help determine how DIRTY your panels are. This is a VERY HANDY DEVICE - every solar user needs a SOLAR LIGHT METER.
