SOLYS 2 is a completely new sun tracker from Kipp & Zonen. It has Baseline Surface Radiation Network (BSRN) levels of performance and reliability. It brings to the sun tracker market distinctive design, innovative features, performance, quality and unprecedented ease of use.

Interest in high quality solar radiation monitoring is increasing in the fields of climate change, meteorology, solar energy and atmospheric physics. This requires the use of a sun tracker to measure the direct irradiance component and (if desired) the diffuse component, that complies with the WMO-GAW BSRN-requirements. The Kipp & Zonen 2AP sun tracker is widely used for this purpose because of its capabilities in extreme conditions around the world. However, for a number of users the 2AP is over-specified. The new SOLYS 2 sun tracker from Kipp & Zonen provides BSRN level performance but is much easier to install and operate than any other tracker on the market.

The key function of a sun tracker is to follow the movement of the sun. This ensures that the pyrheliometer mounted on the side of the SOLYS 2 is always pointing optimally to measure the direct irradiance from the sun. This depends upon accurate location and time information. SOLYS 2 is unique in obtaining this information automatically using an integrated INDUSTRIAL GPS receiver.

After installation and levelling of the SOLYS 2, the power is connected and the GPS automatically configures the location and time data. SOLYS 2 is the only fully automatic sun tracker available that does not require a computer and professional software for setup.
