TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred System: In the solar energy collection system, the modular design allows the serial connection from two to any number of modules. Construction in parts sectioned panels permits the assembly to be half or to one and half times the size of the solar collectors, for installation on building roofs. The system joins a mechanical transmission system formed by: (i) an electric motor power supply (not restricted to this mode) with reduced helical gear; and (ii) a set of sprockets and chain transmission elements as input to the actuator angular motion. It allows angular smooth movement, without oscillations and also automatic locking when the direct current (DC) motor is not energized. The system requires forcibly engaging an electronic control module which allows solar tracking and provides functionality. It consists of the following components: (a) an insulation sensor into a pyramidal arrangement (not restricted to this configuration ) with at least two photo cells or photo- transistors placed one after the other to measure a voltage differential signal and determine the direction and amount of movement of solar collector; (b) a photocell that can detect the level of solar radiation by time of day; (c) an electronic control device based on a microprocessor or microcontroller and power components that calculate the control signals sent to the electrical actuator from angular movement; and (d) an algorithm embedded in the system which governs the operation of the electronics and solar tracking control. The system can be replicated any number of times in arrays of rows and columns, and interconnected with a heat exchanger allowing heat transfer by forced convection for the dehydration of a product. It is interfaced with a parabolic solar concentrator under that collect solar energy at high temperature and heat transfer to the drier chamber using steam or high heat transfer fluid, a recirculation pump and a capacitor. It is interfaced to an array of parabolic solar concentrators and also a thermal support system based on fossil fuels as a furnace, boiler or electric heater. The system is mechanically connected to the same serial number of modules forming a tunnel for longer dehydration and drying energy capacity. It includes an automatic transport system or conveyor product, making more efficient moisture removal and production efficiency. It can be installed and mated with more solar concentrators in two parallel rows. The system can be coupled to a reflectivity sensor placed in the solar radiation receiver. The temperature sensors send signals or solar luminosity that provide feedback to the control system of solar position.
