Uv Light Solar Panels

The solar energy reaching earth s surface includes visible light ultraviolet and infrared radiation.

Uv light solar panels.

Ultraviolet light is high energy and causes damage including sunburn fading of pigments and degradation of compounds such as fabrics plastic and rubber. The panasonic n series of panels are a good quality solar panel with a top efficiency on their 330 watt monocrystalline system of 19 7 and a very impressive temperature coefficient of 0 29 a figure which is equal best with the market leader sunpower. Linked together in a series ss 1100 large led lights can cover any size grow area large or small while drastically cutting energy usage and eliminating the need to change bulbs ever. Infrared has a wavelength of 1 μm while uv is 0 3 μm.

If you get snow in your region during the winter months you ll need to do a few things to keep the light powering up the panels. We can describe it as the transference of energy from the sun through a set of electromagnetic radiations that are distributed in a light spectrum that goes from ultraviolet to infrared radiation. Light output from our full spectrum grow lights promotes photosynthesis at all stages of growth and a comfortable environment to assess and maintain crops. Solar panels absorb the sun s heat and generate energy.

But solar panels only use a small portion of ultraviolet. Sunlight energy that reaches the ground is around 4 ultraviolet 43 visible light and 53 infrared. At night if a panel is pointed toward earth then it could capture the earth s invisible infrared light. Ultraviolet light from the sun will penetrate the clouds and still hit those solar panels in the yard on just about any day even in wintery cloud covered months.

Why uv panels are a con job. Now the energy to excited the electrons in your typical pv panel is 1 1 ev so if e 1 2 λ and e 1 1 then λ 1 1 so so long as the photon have a wavelength less not infrared light it s good. Solar panels mostly convert visible light into electrical energy and they also can make use of almost half the infrared energy. Uv b light 290 320nm causes sunburns with prolonged exposure along with increasing the risk of skin cancer and other cellular damage.

But solar panels only use a small portion of ultraviolet. Uv c light 100 290nm is extremely harmful and is almost completely absorbed by earth s atmosphere. Solar panels mostly convert visible light into electrical energy and they also can make use of almost half the infrared energy. Solar radiation and light spectrum solar radiation is the main source of energy used by solar panels to generate electricity.
