Solar Photovoltaics

Solar cells, also called photovoltaic cells by scientists, convert sunlight directly into electricity. This electricity is direct current in nature and must be converted to alternating current to be used for grid-connected power generation.

Over the last two decades, solar panel efficiencies have increased dramatically, with today’s typical panel efficiency ranging from 12-18%, although efficiencies of more than 40% have been achieved (NREL).

It is becoming widely recognized that the cost of electrical power from solar generation is already below that of conventional centralized thermal electricity generation in many parts of the world. In most of the United States, solar power generation has not reached grid parity, however, government and other subsidies have made solar financially practical. Grid parity occurs when solar generation is equal to or lower than the cost of power from the grid.

The renewable-based hybrid telecommunication power systems designed, constructed and operated by WRH Telecommunications™, use the intelligentRE™ with a cloud-based data repository to monitor and control the hybrid power system. The intelligentRE™ system for telecom blends power flows from a solar and thermal generation with battery storage, to minimize power curtailment and provide continuous reliable power by commanding an optimal balance between power generation, energy storage, and where appropriate, weak-grid or grid energy.
