Product Overview

Since 1910, General Tools has grown to become the recognized industry leader for specialty hand tools and instruments. This digital solar power meter measures solar power in units of watts per square meter or Btu/(ft2 x h) and displays readings on a large 4-digit LCD. It is ideal for checking thermal window efficiency.
  • Measurement range: 0 to 2000 W/sq.m or 0 to 634 Btu/(ft2 x h)
  • Measurement accuracy: ±10 W/sq.m (±3 btu/(ft.2 x h)) or ±5% of reading, whichever is greater
  • Uses cosine angular correction
  • Data hold min/max/avg modes
  • Data memory and read function (99 sets)
  • Auto power-off function
  • Includes tripod mounting screw and a carrying case

This is an easy-to-use solar power meter for checking solar transmission of windows, location and angle of solar panels, or even location of garden beds or greenhouses. The directions are sufficient to get up and running with basic measurements. I’ve used it so far to select a location and angle for a single solar panel at a backcountry cabin, and also to measure incoming solar radiation in open meadows vs. under tree canopies. The light sensor is VERY directional - so you really need to point the white sensor on the top of the unit directly toward the sun to get a good reading. I’m glad to see that General Tools has made this to show readings in W/m2 rather than just BTUs. The function I use most often is the “percent” function - you point the sensor directly at the sun, with no obstructions, set that reading as 100%, and then any subsequent readings indicate the percentage of wattage that is attenuated. For an example, see my photo where the orientation of my small solar panel is receiving 71% of maximum solar radiation.

The General Tool & instruments Company has made this digital solar power meter nice and compact. It can be taken out to the field in your toolbelt or even in your pocket. It comes with the 4 required AAA batteries and instruction manual. I am using this meter to determine placement and the best angle for solar panels. It can also be used to measure window efficiency and window treatments/window film effectiveness.

This solar power meter has a very easy to read digital face even in full sun light. I was able to read the display without a problem. The buttons take a little getting used to being multi functional, but not a big problem. Nice carrying case keeps it in good shape when not in use. Mounted easy to tripod (not included) with the provided nut to attach. I was able to get the best angle for my panel positions.

This is a fantastic solar power meter! It is incredibly useful when installing solar panels, or planning where to put your garden. The meter features several handy features including measuring in Btu/(ft2 x h) or W/m^2. It is capable of measuring solar power over a period of time and displaying the average, which is fantastic for mounting solar panels to maximize their efficiency. Additionally, the meter comes with a tripod mount for long duration measurements. This is definitely a must have tool.

Five Stars for performance. I found it very useful in setting up my single (for now) solar panel, making adjustments as to angle, etc. The solar meter showed me at a glance the best position and angle for the solar panel. The solar meter performs other tasks as well, such as showing the difference in solar energy with window roller shades open or closed, giving a solar transmission measurement. It's useful for some agricultural purposes, such as in a greenhouse. For the cost, it would be more useful for the professional who installs solar panels or maybe roller shades on a regular basis.
