Robot for Solar Farms

The solar energy and solar farms are used to generate energy and reduce dependence on oil (or for environmental purposes). The maintenance and repairs in big farms become very difficult, expensive, and inefficient, using human technicians. Thus, here, we teach using the robots with various functions and components, in various settings, for various purposes, to improve operations in big (or hard-to-access) farms, to automate, save money, reduce human mistakes, increase efficiency, or scale the solutions to very large scales or areas.

System And Method For Identifying The Solar Potential Of Rooftops

A system and method for identifying the solar potential of rooftops. In one embodiment, solar-potential criteria and three-dimensional spatial data and tabular data, for a selected area including parcels on which the rooftops are located, are entered into a geographic information system. Three-dimensional aerial data of the selected area, including the rooftops in the selected area, is collected. Solar azimuth and altitude angles are calculated for regular intervals to generate shadow simulation data representing shadows cast onto the rooftops by obstructions. The shadow simulation data is intersected with the XYZ coordinates of the rooftop shapes, as determined from the aerial data, to generate rooftop shade patterns for specific intervals over a specific period of time. The tabular data and the rooftop shade patterns are then used to determine addresses and per-parcel specifications of buildings having said rooftops meeting the solar-potential criteria.

Solar cogeneration vessel

InactiveUS20120325290A1Reduces Levelized Cost OfMinimizes another factorSolar heating energySolar heat simulation/predictionData acquisitionCogeneration
An offshore vessel embodies a mobile buoyant energy recovery system enabled to extract energy from solar power. An exemplary energy recovery system comprises concentrating solar thermal power systems (CSP) or concentrating photovoltaic power (CPV) systems on the deck of the vessel. Within the vessel hull, ballast water serves multiple purposes. The ballast not only stabilizes the vessel, but also provides reactant for hydrogen electrolysis or ammonia synthesis, or steam for a turbine. For CPV systems the ballast conducts heat as a coolant improving the efficiency and durability of photovoltaic cells. For CSP systems the ballast water becomes superheated steam through a primary heat exchanger in the concentrator. In some embodiments, some steam from the CSP primary heat exchanger or from the CPV coolant system undergoes high-pressure electrolysis of enhanced efficiency due to its high temperature. In some embodiments, the remaining steam that did not undergo electrolysis drives a steam turbine providing electrical current for electrolysis. A secondary heat exchanger takes heat from the steam expelled from an energy storage process to efficiently distill ballast water at a lower temperature thus minimizing corrosion and build-up of scale. A remote control Supervisory Control and Data Acquisition System (SCADA) determines position, navigation, configuration, and operation of the preferably unmanned modular mobile buoyant energy recovery structure based on Geospatial Information Systems (GIS), Velocity Performance Prediction (VPP) models, Global Positioning Satellites (GPS) and various onboard sensors and controls.

The invention, the Concentrated Solar Thermoelectric Power System, herein abbreviated as C-STEPS, is a thermo-optical system configuration for the purpose of achieving a high solar energy-to-electricity conversion efficiency based on thermoelectric (TE) devices that use the Seebeck effect. It does so by implementing a system for concentrated solar energy using a design that combines a dual-function reflector / radiator component with an active or passive heat convection mechanism to ensure that TE module operation is maintained in a safe elevated temperature range with respect to the ambient temperature. Unsafe module temperatures are avoided by automatically adjusting the TE module hot side temperature directly or indirectly by regulating the TE cold side temperature using a variety of passive or active mechanisms, including the reflector / radiator component, phase change material, or convection / conduction mechanisms. A Numerical Design Model is used to optimize the configuration geometry and performance in various terrestrial and space applications and it is a central feature of the invention.
