Suncalc Sunlight Calculator


Plants can't thrive if their specific sunlight needs aren't met. Too much sun for some plants means they get scalded—too little, and they wither. SunCalc tells you the the exact amount of sunlight you have in different areas of your yard so you never have to guess the ideal spots for your plants. View it here:

The SunCalc has been in development for a number of years. Our goal has been to give gardeners and landscapers a precision instrument that is affordable and easy to use.

STEP 1: Select a day when you can reasonably expect a full day of sunlight.

STEP 2: Start early in the day (7-9 am). Place the SunCalc in the desired location for evaluating the amount of available sunlight. We recommend that the unit be placed in a flower pot filled with soil, but it can also be placed directly in the ground. Please make sure that the face of the unit is generally parallel to the ground. We want to make sure that the SunCalc is measuring the sun's rays in the same way that the plant's leaves receive the sun.

STEP 3: Press the power switch located on the shoulder of the device to turn the SunCalc on. When the power is applied, the Full Shade through Full Sun LEDs will illuminate sequentially for approximately 2 seconds. Thereafter, the four LEDs will flash every 2 seconds, indicating the sunlight accumulation is in progress.

STEP 4: After 12 hours of continuous operation, the device will cease to accumulate solar data and a single LED will illuminate to indicate the light threshold achieved in that location. Full Sun, Partial Sun, Partial Shade, Full Shade.

Suncalc Facts:

  • The Sunlight Calculator must remain on for a minimum of 12 hours in order to achieve a light threshold reading.
  • Do not store your Sunlight Calculator in temperatures below 32 degrees. Freezing temperatures will significantly reduce battery life.
  • The Sunlight Calculator is a precision measuring device and should be used only as directed. Depressing the on/off button in rapid succession for long periods could affect the units operating system and cause the unit to malfunction. Should this occur, remove the SunCalc battery for 10 seconds, then reinstall and restart the unit.
  • Water-resistant... not waterproof. Rain or sprinklers will not affect the unit's operation. However, do not submerge unit in water.
  • SunCalc is designed to calculate sunlight conditions during the planting/growing season.
