Utilization of solar systems to harvest atmospheric moisture for various applications including panel cleaning

A solar energy collection system that includes a system for generating water using an absorption refrigeration cycle in lieu of an electrical compressor, wherein the generated water can be used for cleaning the solar energy collection system and for other purposes, comprising:

• a solar collector having a first surface exposed to solar energy and a second surface opposite the first surface;
• an absorber, the absorber containing a working fluid that includes a solution of a coolant fluid and an absorption fluid;
• a generator fluidly connected to the absorber for receiving the solution from the absorber, the generator being supported by the solar collector such that at least a portion of the solar energy can be absorbed by the solution to separate the coolant fluid from the absorption fluid, wherein the generator is fluidly connected to the absorber to return the absorption fluid to the absorber;
• a condenser fluidly connected to the generator to receive the coolant fluid;
• an evaporator fluidly connected to the condenser to receive the coolant fluid, the evaporator being supported adjacent the second surface of the solar collector and arranged such that the coolant fluid can affect a heat transfer to lower the temperature of the solar collector and is further capable of causing atmospheric water to condense on the solar collector;
• wherein the absorber is fluidly connected to the evaporator to receive the coolant fluid, the absorber providing a chamber in which the coolant fluid and absorption fluid can combine to reform the working fluid solution;
• and
• a cleaning system, comprising;
• a water collector disposed at a lower end of the solar collector, the water collector being capable of collecting water that can travel across the surface of the solar collector;
• and
• a nozzle disposed at an upper end of the solar collector, the nozzle being fluidly connected to the water collector, the nozzle being capable of spraying at least a portion of the water collected by the water collector on the first surface of the solar collector to clean the first surface of the solar collector, while further portions of the water collected remain available for the same cleaning operation or for other applications,
• wherein the solar collector can include one or more condensation panels which define fins configured to be chilled by the coolant fluid.

A method for cleaning a solar energy collection system that includes generating water using an absorption refrigeration cycle, comprising:

• generating water on a first surface of a solar collector by operation of a refrigeration system, the first surface being exposed to solar energy, and the solar collector having a second surface opposite the first surface;
• operating the refrigeration system, comprising the steps of:
• transferring a working fluid that includes a solution of a coolant fluid and an absorption fluid from an absorber to a generator fluidly connected to the absorber, the generator being supported by the solar collector such that at least a portion of the solar energy can be absorbed by the solution,
• separating the coolant fluid from the absorption fluid as a result of absorption of at least the solar energy, wherein the generator is separately fluidly connected to the absorber and a condenser,
• returning the separated absorption fluid to the absorber;
• transferring the separated coolant fluid to the condenser wherein the separated coolant fluid condenses;
• transferring the condensed coolant fluid to an evaporator fluidly connected to the condenser, the evaporator being supported adjacent the second surface of the solar collector and arranged such that the coolant fluid can affect a heat transfer to lower the temperature of the solar collector;
• causing water to condense out of the atmosphere and onto the first surface of the solar collector as a result of heat transfer between the coolant fluid in the evaporator and the solar collector;
• returning the coolant fluid to the absorber, wherein the absorber is fluidly connected to the evaporator to receive the coolant fluid, the absorber providing a chamber in which the coolant fluid and absorption fluid can combine to reform the working fluid solution;
• and
• cleaning the first surface of the solar collector by allowing the condensed water to traverse the first surface of the solar collector as a result of gravity acting on the condensed water.
