Parabolic Trough Solar Panels

Parabolic troughs which are a type of linear concentrator are the most mature csp technology with over 500 megawatts mw operating worldwide.

Parabolic trough solar panels.

Solar collector in the shape of a parabolic mirror reflects the incident solar energy on the longitudinal axis of the solar collector. Doe funds solar research and development r d in parabolic trough systems as one of four concentrating solar power csp technologies aiming to meet the goals of the sunshot initiative. Csp systems use the sun as the thermal heat source as opposed to the photon energy of the sun as pv systems do. This is primarily due to nine large commercial scale solar power plants the first of which has been operating in the california mojave desert since 1984.

The fluid flows through this tube and absorbs heat from the concentrated solar energy. Heavy duty light weight and durable. Parabolic solar trough creates solar energy solar hot water steam cooker pressure a steam engine this solar trough tracks the sun using a mathematical algorithm and will not chase shadows from clouds. Solar parabolic trough 1 0 system description parabolic trough technology is currently the most proven solar thermal electric technology.

Most electric power plants use some form of fossil fuel as the thermal heat source to boil water into steam. These troughs can track the sun around one axis typically oriented north south to ensure the highest possible efficiency. A parabolic trough is a type of solar thermal collector that is straight in one dimension and curved as a parabola in the other two lined with a polished metal mirror. If it is sufficient this solar energy alone can operate the plants at the full rated power.

In a solar cooker for example food is placed at the focal line of a trough which is cooked when the trough is aimed so the sun is in its plane of symmetry. Parabolic trough collector for solar power. This line is called the focal axis of the parabolic collector. Parabolic trough solar systems concentrated solar power csp systems use very different technology than photovoltaic systems.

During summer months the plants operate at full rated electric output for 10 12 h day. Parabolic trough is a set of concave mirrors that concentrate solar rays on the receiver tube that is located in the focus. Patented parabolic trough reflectors uses the latest. The parabolic trough reflector is a solar thermal energy collector designed to capture the sun s direct solar radiation over a large surface area and focus or more generally concentrate it onto a small focal point area increasing the solar energy received by more than a factor of two which means more overall heat per square meter of trough.
