Solar Power Meter, Handheld Solar Irradiance Meter Solar Energy Meter, Digital Solar Power Meter with 2000 W/m2, 634 BTU / (ft2 · h) Measuring Range and MAX/MIN/Data Hold Function

Helped me to figure out the issues with solar panel. I used it to monitor solar activity and solar panel performance. One day I found reduced performance of solar panel at the same solar activity.

I purchased this on the advice of a "biohacker blogger" to test the irradiance of photobiomodulation units. While they aren't meant to be completely accurate, because of the various factors involved in testing, for the price you pay, and the conditions, they do give you a very usable result. They're definitely recommended for the purpose described. Also - when I was having problems with the device, I received a very fast reply from customer services - and several follow ups to make sure that the problem had been solved. I recommend both the product and the company.

Great for readings under 200btus. Anything above reads error

Bought this tool to try and evaluate positioning of solar panels for installation. Meter was easy to use and gave good readings and helped me evaluate angles of installation for a backyard pergola. Only wish I could correlate meter readings to actual solar panel output. When my solar system is installed I will be able to compare meter readings to actual solar panel output.
