The ES2 energy sensor is designed for solar energy studies in unobstructed daylight. The ES2 has high stability and low temperature coefficient silicon photodiodes, has a self cleaning dome and a good cosine response with an infinity-error correction ring. There is an internal calibration adjuster for annual calibration. 
This sensor is only available through the purchase of the GP1 weather station, and is a great sensor for low cost light studies. It measures total shortwave solar radiation.
