According to the US Department of Energy modeling, there is a very simple way to get a file Solar Panels Improve efficiency, which most users can do almost for free. Experts have taken into account factors such as row spacing between panels, how high the units are, and how inclined they are. In addition, a longitudinal inlet was used to characterize the space through which air moves around or through the solar modules. In standard models, on the other hand, the length dimension often used is the ratio of unit sizes, which ignores the PV plant configuration, according to PV . magazine from his summary.
“The convective heat transfer curve was generated with the help of computational flow simulations and wind tunnel experiments, which made it possible to describe convective heat transfer to a gap-length scale value that describes the distance of the entire set of PV modules by a single length unit,” the scientists think. Translate into the language of the kitchen It means that the heat transfer occurs in such a way that the heat transfer flows towards the heat absorbing and warming molecules. For example, when water is heated in a pan, the water molecules on the hot bottom of the pan first absorb heat from the bottom of the pan, heat up, and then “start” the molecules up. Laconism measures the size of the gaps between the rows of panels. In other words, it is important how the heat flows between the plates, the distance to be traveled, but at the same time the heat transfer must also be adjusted to the optimum operating range of the plates.
The latter is the key to solar cells: if air can flow properly a solar power plants Among its ranks, solar energy production could be 1.5 percent more efficient. The trick is to take into account the prevailing wind direction when placing the panels. Row spacing for PV plants ranged from 2 to 11 m, and the best solution was about 9.8 m in the studied locations, but depending on climatic conditions, this could be lower.
Distance can also be important for garden photovoltaic cells, but the gap between the roof and the panel, combined with adequate wind cooling, can also affect efficiency. If the appropriate space is available, it can be improved almost free of charge by optimizing tilt angles and row spacing energy production for these systems.
Agricultural production can also improve income
“Increasing row spacing could allow us to use more types of crops and more types of agricultural equipment in agricultural systems,” said Jordan McNick, who leads another research project at NREL focused on voltage farming.
“This could make these distributed solar systems more cost-effective and compatible with industrial agriculture,” he added.
Other recent suggestions for using solar thermal cooling include placing photovoltaic panels close to each other taking into account wind direction and unit tilt.
