Solar is a key component of Dominion's clean energy growth. We have several exciting generating facilities and projects, solar partnership and purchasing programs, and more than 1,900 customers with solar panels installed at their homes or businesses. These efforts support our philosophy to balance our generation portfolio with all types of fuel sources, including nuclear, coal, biomass, natural gas, water, wind and solar.
Since 2013, Dominion has helped bring more than 1,000 megawatts of solar into operation in the U.S., enough energy to power about 250,000 homes at peak solar output.

About Solar Generation
Solar Photovoltaic Systems
Solar Photovoltaic (PV) and Concentrated Solar Power (CSP) systems are the two main types of solar technology used in electric power generation. Concentrated Solar Power systems utilize mirrors to reflect and concentrate sunlight onto receivers to convert solar energy into thermal energy that in turn produces electricity. CSP systems are generally used in large scale solar plants and are mostly found in the southwestern area of the country where solar resource potential is the highest.
All solar facilities in operation, under construction, or under development by Dominion utilize solar PV technology. Solar PV systems consist of interconnected PV cells that convert sunlight into electricity. Solar PV technology is found in both large-scale and distributed systems and can be implemented where unobstructed access to sunlight is available. Solar PV technology has continued to evolve and is one of the most rapidly growing renewable energy sectors. In 2015, 30% of all new electric generation capacity in the U.S. came from solar. Continuing enhancements in inverter technology are increasing the efficiency and output of solar PV systems.
Due to the decreasing costs of solar modules and increasing standardization of installation techniques, solar resources are becoming less expensive and more attractive options. Additionally, federal tax credits for solar have helped make this resource more cost competitive. However, installed costs can vary widely depending on system size, technology types, and site specific factors. A solar cell’s output depends on various factors, such as its design and materials, the intensity of the solar radiation hitting the cell, and the cell’s temperature.
Due to its intermittent nature as a generating resource, solar PV generation is not dispatchable and contributes less to peak load and reserve requirements than conventional generation resources. Continuing technological advancements, especially advancements in energy storage capability, may help mitigate this intermittency and make solar PV facilities more dispatchable in the future.
