Using mirrors on solar panels.

Mirrors don t really help at all on cloudy days because they only reflect incident light relative to the direction it came from. Concentrated solar technology systems use mirrors or lenses with tracking systems to focus a large area of sunlight onto a small area. This arrangement could help offset the impact of new tariffs on imported solar cells but the current design of many utility scale solar farms wastes this potential gain in energy. The tracking mirrors are encapsulated in the panels.

On a dull day the mirror doesn t give much of a power boost at. Placing a mirror next to a solar panel boosts output by as much as 30. Isp s patented panel level intensifying solar technology incorporates conic mirrors that intensify the sun s rays 20 times isp modules then require just 1 20th of the pv cells of traditional panels to deliver the same performance. Placing mirrors either side of the panel to reflect doesn t work well because as the sun moves west it will cast a.

There are eight heliostats on a pod with the mirrors motors operated by small two watt photovoltaic solar panels explained chief technology officer brad hines. Mirrors are used much more in solar thermal systems because increasing the light intensity in one places raises the temperature which raises the thermodynamic efficiency of the system. The concentrated light is then used as heat or as a heat source for a conventional power plant solar thermoelectricity. A study showed that reflectors on solar panels can increase their performance by up to 30 the continuing drop in cost for home solar power generation has led to a dramatic increase in the rate of installations for both residential and commercial use.

Increasing the yield through reflection could make that an even m.
