Solar Panels Above The Clouds

Yet when the sun shines through the clouds solar panels still get direct sunlight plus light reflected from the clouds.

Solar panels above the clouds.

Meeting the challenge there are ways to meet the cloud challenge. Anyone who has gotten sunburned on a cloudy day knows that solar radiation penetrates clouds. One option is to mount solar panels on balloons whether moored or mobile. It just reduces the output of energy.

So why not send solar cells up above the clouds where the sun always shines. The thing is when clouds cover the sun the solar system doesn t stop working producing power. They will see complete direct sunlight plus reflected light from the clouds. For that same reason solar panels can still produce electricity on cloudy days.

The effects of clouds on a solar panel could then produce peaks at or above 50 percent more than its direct sun output. As the sun moves into a hole between the clouds your photovoltaic panels will see something wonderful.

If clouds are in the way even the best solar panels don t work that well. The thicker the clouds the less power the system will produce. Several projects have already demonstrated the feasibility of using balloons at altitudes well above 20 km. But depending on the cloud cover and the quality of the solar panels efficiency can drop to anywhere from 10 to 25 percent of the energy output seen on a sunny day.

The researchers claim that solar yields from a system of solar panels deployed above the clouds 6 km or 3 7 miles above the ground could be multiplied when compared with ground based solar. The amount of direct sunlight is reduced by fog and clouds but solar panels function better at cooler temperatures so the electricity output in san francisco is still significant. In 2006 germany opened the largest solar park in the world. If you often have clouds in the afternoon but.

Solar farms have been making headlines lately and solar power options are gaining in popularity as their efficiency levels improve. Germany also has europe s most modern solar housing project a solar village of 50 solar houses that produce more energy than they use.
