Disclosed is a portable and compact hybrid power unit for ready to use, plug-in power for nearly any environment. Open Energy System (OES) is self-contained in a durable shell that can be deployed almost anywhere in the world. The OES transforms from a rugged box into an energy generating unit with all equipment assembled and ready to generate power. Pre-assembled solar modules can slide out from the opening sides of the unit along a rolling channel, lock into place and open into a ready-to-generate solar electric array. In addition, the OES is mobile and transportable. It can hitch to a vehicle, be dropped in by helicopter, shipped in or used as a permanent unit. Further, the OES unit is designed to fit 5 to a standard shipping container and can be deployed using various shipping methods.
