Embodiment Construction

[0041] Certain aspects of the invention provide monitoring systems for solar panel systems. The monitoring system includes modules that can be attached to each solar panel of a solar system. The monitoring module will monitor different parameters including, for example, panel voltage, panel current, panel temperature, illumination conditions, spatial orientation (eg, tilt), and other parameters. The information obtained by each monitoring module can be sent to the central management unit together with a unique module ID. This transmission can be done over power lines, wirelessly, or using dedicated wiring - such as Ethernet, RS-232, RE-485 or others. In one aspect of the invention, the sending is done in power line communication implemented unidirectionally. Collisions are eliminated or minimized by using a unique transmit timing mechanism.

[0042] This central management unit can analyze the data obtained from all solar panels. The monitoring system can be done at the st...

Abstract

A monitoring system and method for monitoring performance of individual powers sources in a distributed power source system. A monitoring module is coupled to each of the power sources, or to each string of serially connected power sources, to monitor and collect data regarding current, voltage, temperature and other environmental factors at the power source. The collected data is transmitted over a power line to a central analysis station for analysis. Data collected from each source indicates malfunction or degradation at the source. Comparison of data collected from adjacent sources filters for environmental factors impacting neighboring sources such as cloudy days for a solar panel. Comparison of data collected from the same source at different times indicates soiling or degradation of the source with time or periodic events such as a moving shade from an adjacent building.
