Building Environment Division NIST’s Solar Photovoltaic System A portion of the energy used at the NIST campus in Gaithersburg, MD is being provided by renewable energy. A solar photovoltaic system is being installed on the roof that connects the main Administration Building to its adjoining conference and cafeteria facilities. The solar system will reduce the quantity of electricity purchased to power the NIST campus and reduce the monthly peak demand charges. The system consists of 234 photovoltaic modules and associated electronics. Each module, containing 72 monocrystalline photovoltaic cells, produces up to 4.8 amps of direct current electricity at 34 volts under ideal solar conditions. The individual modules are interconnected with the resulting electrical output converted to alternating current by means of an inverter. The system will power the lights in four floors of the Administration Building, approximately 600 lights. Extruded polystyrene insulation panels, on which the modules are mounted, provide additional roof insulation reducing the heating and cooling loads to the building. The system is projected to generate approximately 33,000 kilowatt hours of electricity on an annual basis, enough energy to meet the total electrical needs of three to four average residences. During nighttime conditions, the building receives all of its electrical power from the local utility in a normal manner. No batteries are used in this grid-interconnected system.

SOLAR PHOTOVOLTAIC WATER HEATING SYSTEM FLORIDA SOLAR ENERGY CENTER A single-tank, solar photovoltaic hot water system is presently being evaluated at the Florida Solar Energy Center (FSEC). The system uses an array of photovoltaic cells (pictured at right) to convert sunlight into direct current (DC) electricity. The electricity generated by the photovoltaic cells depends mainly on the solar intensity and the connected load that uses the electricity. This connected load must change as the solar intensity changes in order to maximize the efficiency of the sunlight-to-electricity conversion process. In the single-tank solar hot water system, combinations of three, microprocessor-controlled heating elements are used to provide the changeable load. The electricity generated by the array is supplied to a storage tank by means of conventional house wiring. The flow of electricity is regulated by a microprocessor-based controller that monitors the solar intensity, exercises the efficiency-maximizing control logic, and connects the appropriate resistive elements. A single solar cell that is mounted with the array provides the controller a signal that is proportional to the solar intensity. Beginning with a conventional electric water heater, the controller is mounted on the tank's exterior (see adjacent photograph). The tank's lower heating element is replaced with an assembly having three heating elements. These three elements heat the entire tank using the electricity generated by the photovoltaic array. The upper part of the tank contains a heating element that is connected to the electric utility grid. This upper element insures the availability of hot water during poor solar conditions and its use, in general, avoids having to oversize the photovoltaic array. A computer data acquisition system is used to impose hot water draws and to monitor overall system performance (e.g., energy inputs, energy outputs, solar irradiance, several air and water temperatures). Testing of the single-tank system will continue until the Spring of 1999. The project is the result of a cooperative effort between FSEC and the National Institute of Standards and Technology (NIST)

Wind Power Small Hydro Power Solar Electricity Wave Power Photovoltaic systems are solar systems that produce electricity directly from sunlight. electricity translated simply means means "light electricity." Photovoltaic cells are generally made from thin wafers of silicon. Silicon tends not to conduct electricity, however, if chemicals are added - usually boron and phosphorous - and the silicon is heated to extreme temperatures, the silicon atoms can become slightly unstable. So when photons of sunlight hit a solar panel, some are absorbed into the solar cells and this energy knocks loose some of the modified silicon's electrons. These loose electrons are forced by electric fields in the photovoltaic panel to flow along wires that have been placed within the cells.

Home About ELC Site Map Contact Us ... Food Solar Energy Most of the energy we use originates as solar energy. Through photosynthesis, plants convert solar energy into chemical energy, which is converted into fossil fuels and biomass. Solar power is responsible for wind power, thermal energy, and hydroelectric power. Directly harnessing sunlight as a source of energy in a cost-effective way remains a challenge and active solar systems still provide only a small percentage of the world's energy needs. The Sun's energy can be exploited in various ways. Passive solar heating is the simplest method and these systems reduce heating and cooling costs through siting a building as well as through using windows and other materials to collect and hold heat. Active solar systems, usually collect the Sun's heat with large panels through which air or liquid is pumped into a storage area and then recirculated. New research is focused on developing cost-competitive photovoltaic cells, which convert the sun's energy into electrical current. Photovoltaic cells remain costly and therefore have not been as competitive as other energy technologies. In remote regions, however, photovoltaic cells may be an important option.

Energy sources different from those in widespread use at the moment (which are referred to as conventional). Alternative energy usually includes solar, wind, wave, tidal, hydroelectric and geothermal energy. Although they each have their own drawbacks, none of these energy sources produces significant air pollution, unlike conventional sources. fossil fuels. Carbon or hydrocarbon fuels, derived from what was living material, and found underground or beneath the sea. The most common forms are coal, oil and natural gas. They take millions of years to form. Their energy is only released upon burning, when the carbon and hydrogen within them combine with the oxygen in air to form carbon dioxide (CO ), or carbon monoxide (CO) and water (H O). Other elements within the fuels (such as sulfur or nitrogen) are also released into the air after combining with oxygen, causing further pollution with SO and nitrogen oxide gases. In the case of coal, ash particles are also a problem.

for PVWATTS calculates electrical energy produced by a grid-connected photovoltaic (PV) system. Currently, PVWATTS can be used for locations within the United States and its territories. Researchers at the National Renewable Energy Laboratory developed PVWATTS to permit non-experts to quickly obtain performance estimates for grid-connected PV systems. In a grid-connected PV system, PV modules, wired together to form a PV array, pass DC electricity through an inverter to convert it into AC power. If the PV system AC power is greater than the owner's needs, the inverter sends the surplus to the utility grid for use by others. The utility provides AC power to the owner at night and during times when the owner's requirements exceed the capability of the PV system.
