Solar photovoltaic (PV) or electric power generation systems harness the energy of the sun to create clean, cost-effective electricity.
A grid-tied solar electric system provides power by converting the sun’s light to direct current (DC) electricity. The solar electricity produced is converted into alternating current (AC) electricity by the inverter and then fed into the main distribution system to offset the electricity demand in the facility. Any excess solar electric generated is exported back to the utility grid (Net Metering). When sunlight is not present the facility imports power directly from the grid.
Solar energy systems work in parallel to the grid, providing the best possible combination of reliability, pricing and sustainability benefits. In addition, these systems integrate seamlessly with existing building structures resulting in zero impact to day-to-day building operations and performance.
The primary components of a solar PV energy system are as follows:
- Solar Photovoltaic (PV) modules
- Mounting hardware
- Disconnects / Switches
- Performance monitoring system
