The device has utility in environments such as that found in offices, schools, homes, industrial plants or any other type of automated facility in which sensors are utilized for energy monitoring and control, end user convenience or artificial or natural cooling, heating and HVAC control. The device can be used as a switch or dimmer, sensor or thermostat as well as to adjust and control all natural and artificial lighting, temperature and humidity devices. Key elements of the invention include overcoming the difficulty of mounting diverse sensors or transducers within the same device or housing; permitting these various sensors to exist in a single package that can be mounted to a wall in a substantially flush manner; and eliminating the requirement of an air flow channel in the device, thus minimizing any adverse effects on the motion detecting element or sensor as well as providing built in partial hysteresis. The device may include additional transducers or sensors and is constructed such that the temperature and humidity sensors are neither exposed to the flow of air in a room or area nor in an airflow channel whereby a chimney effect may occur. The device can transmit and receive real time data, relative data and actual discrete data in addition to switching and controlling loads locally or remotely. An embodiment utilizing airflow channels to direct air over the temperature and humidity sensors is also disclosed.

A preferred solar panel of rectilinear geometry has n row of m solar cells each row in a regular grid array. The cells constituting each row are wired in parallel. The rows are wired in series and an equalizing network of (1) n−1 capacitors 1, 2, 3, . . . n−1 connected in electrical series and (2) a network of switches. The switch network connects at one, first, time capacitor 1 across the parallel-connected cells of the 1st row, and capacitor 2 across the parallel-connected cells of the 2nd row, and so on until capacitor n−1 is connected across the parallel-connected cells of the [n−1]th row. The switch network connects at another, second, time capacitor 1 across the parallel-connected cells of the 2nd row, and capacitor 2 across the parallel-connected cells of the 3rd row, and so on until capacitor n−1 is connected across the parallel-connected cells of the nth row. This causes the voltage across each row to be substantially equal to the voltage across every other row. Since equal voltage is a hallmark of parallel connection, this voltage equalized series connection is referred to as a virtual parallel connection. The end result is that the voltage across each cell in the panel is substantially equal to the voltage across every other cell in the panel, but the voltage presented at the panel terminals is n times the voltage on any cell, and the current presented at the panel terminals is the sum of all of the cell currents divided by n.
