Abstract: Modular solar systems comprise one or more module units that are connectable into a system/assembly for convenient installation on a roof or other surface that receives solar insolation. The modules are adapted for electrical, and preferably also mechanical, connection into a module assembly, with the number of modules and types of modules selected to handle the required loads. Each module is adapted and designed to handle the entire power of the assembly and to provide or receive control signals for cooperative performance between all the modules and for monitoring and communication regarding the assembly performance and condition.

Abstract: A vehicle guidance system (VGS) facilitates interaction between human operated vehicles (HOV), autonomous driverless vehicles (ADV), and/or semi-autonomous vehicles, on the roadway, allowing safe interface with each other and with other elements, for example, weather conditions, traffic control systems, road conditions, obstructions that enter the roadway (people, rocks, animals, debris falling onto roadway from other vehicles), etc. The system provides guidance, communication, and control for the vehicles on the roadway, by using a solar-powered system comprising post assemblies having solar panel(s), sensors, forward and/or downward lighting, and other indicators/alarms to signal to the vehicle or driver regarding road, bridge, weather, accident, speeding, or other conditions of concern in the vicinity for safety and/or operability of the vehicle/driver(s).
