dec-solar is the maintenance-free software control package for solar energy plants. dec-solar reports alarms and controls the plant. Relevant plant data are logged and represented in reports:

• power produced (total / per inverter)
• solar tracker position control
• weather conditions at the plant
• manual control of the solar trackers and calibration

The data can be presented in a web page or alternatively access can be granted via a secure terminal connection. The data can be stored locally or in a remote server. In case of too harsh weather conditions, dec-solar sets automatically the panels to safe position. 

Decuna's dec-trac solar tracker controllers have been designed to minimize installation costs and spare maintenance in solar power plants.

dec-trac is robust, low-cost, and uses standard components. It is conceived for mass production. Several versions have been adapted to different solar tracking modes:

• electric or hydraulic drive
• roof-top mount or ground installation
• 1-phase or 3-phase motors
• tracking in 1 or 2 axis
• standalone or central control
• open control loop or closed control loop (with encoder o inclinometer)

dec-trac is accurate (0,001 degrees) and suitable for demanding applications such as heliostats (solar tower technology) or concentrated photovoltaic power (CPV).

dec-trac can even control the inverters, using just one control network with ring topology for reliability and redundancy. It integrates seamlessly with the control software package dec-solar, visualizing the actual plant state and extracting relevant data with reporting tools.
