Single-Axis and Dual-Axis Solar Tracker

Solar trackers increase the efficiency of solar systems by providing more direct sunlight on the collectors. Depending on the location and the specific system, 25% to 40% more energy can be harvested with tracking than without it. Active and Passive Trackers Solar trackers can be categorized as either active or …

Solar Concentrators Types & Applications

Concentrating Photovoltaic System

A solar concentrator collects light over a certain area and focuses it onto a smaller area. The light can be focused with either a lens or a mirror. For PV systems, the concentrator can increase the amount of electrical power from each cell in the array. An important application for …

Grid-Tied Solar Photovoltaic (PV) System

residential grid-connected PV system

Most PV systems are grid-tied systems that work in conjunction with the power supplied by the electric company. A grid-tied solar system has a special inverter that can receive power from the grid or send grid-quality AC power to the utility grid when there is an excess of energy from …

Stand Alone Solar PV System

Designing a solar PV system requires a systematic approach. The first step in sizing a stand-alone solar PV system is to perform an energy audit, looking for places to save energy. The power requirements are evaluated as part of the audit, and the site is evaluated for the expected solar …

Solar Panel Data Sheet: Specification & Parameters

solar module data sheet

The most important solar panel specifications include the short-circuit current, the open-circuit voltage, the output voltage, current, and rated power at 1,000 W/m2 solar radiation, all measured under STC. Solar modules must also meet certain mechanical specifications to withstand wind, rain, and other weather conditions. An example of a solar module …

Concentrated Solar Power (CSP) Technologies

Concentrated solar power (CSP), also known as concentrating solar power, solar thermal power, or solar thermal electricity, uses glass mirrors of different architectures to collect the sun’s thermal energy and convert it into electrical energy. This is achieved via conventional thermodynamic power cycles that are adjusted to the specific needs of …

Photovoltaic (PV) Cell: Working & Characteristics

Photovoltaic (PV) cells, or solar cells, are semiconductor devices that convert solar energy directly into DC electric energy. In the 1950s, PV cells were initially used for space applications to power satellites, but in the 1970s, they began also to be used for terrestrial applications. Today, PV cells are used …
