With the optional top mounting plate and shading assembly, SOLYS2 can be configured as a complete solar monitoring station with up to three ventilated Kipp & Zonen radiometers. A large range of mounting kits is available for direct solar radiation instruments.

An advance over conventional sun trackers is the integrated GPS receiver to automatically configure location and time data upon installation. SOLYS2 does not require a computer and software for setup. Levelling is easily checked using the integrated bubble level on top.

The rugged and distinctive cast aluminium housing has an integrated tripod stand with levelling feet, tie-down bolts and azimuth adjustment. A side plate with zenith adjustment and mountings for a Kipp & Zonen CHP1 pyrheliometer is included.

The SOLYS2 does not suffer from internal clock drift because the time is regularly updated by the GPS receiver. If the tracker is correctly levelled and aligned it will continue to point accurately. An optional sun sensor is available for active tracking.

The SOLYS2 can operate from AC or 24 VDC power, both inputs are available as standard. The operating temperature range from - 20 °C to + 50 °C can be extended to -40 °C on AC power using the standard internal heater.

SOLYS2 brings to the sun tracker market distinctive design, innovative features, performance, quality and unprecedented ease of use – all at a surprisingly affordable price.
