Introduction to solar street light

The growing importance of installing solar street lights have been realised by governments, households and commercial complexes. Solar energy is free and replenishable. Installing them means, not having to depend upon the dwindling conventional resources like coal and petroleum.

Will solar floodlights work in cold winters?

There are places that experience long, cold winters. If you reside in such areas, then you need to first research and find out if it will be wise to invest in solar street lights or not at your place. Otherwise, it will be sheer wastage of money.

How electricity is produced in solar street lights from solar energy?

Solar street lights comprise of solar photovoltaic cell that again contains silicon, a semi-conducting material. It produces chemical reaction when exposed to sunlight. This, in turn, releases electrons, charge-bearing particles that flow as electrical current through the circuit. This electrical flow is then transferred into a battery to store it in the form of chemical potential energy. Another light sensor referred to as the photocell allows power at night to flow via the circuit comprising of an LED light. The light burns all the night until there is daylight that figures the photocell. The light then turns off. Buying quality solar street light products from the reputed Solar street light manufacturer will be necessary to derive long-term benefits.

Can solar energy be stored on cloudy days?

The truth is the sun’s energy is not just collected by the solar cells through direct sunlight. Rather, it also works on rainy, cloudy and snowy days. Solar cells manage to generate power derived from direct sunlight as well as from diffuse irradiation. Here, the blue-coloured diffuse sunlight tends to charge solar cells during daylight even in the absence of direct sunshine.

Hence, the question is can the solar cells generate sufficient amount of energy in winter to power the solar street lights?

How long will solar street light take to be fully solar engry？

Solar street light specifications differ. Typically, it requires about direct sunlight for about 6-8hours to charge fully its battery. The light is likely to operate for 4-6 nights using fully charged battery. Discussing with the industry professionals at https://ycsolarlight.com/ will allow you to get a better idea.

What is the amount of direct sunlight received at different locations？

Sunlight received during peak solar hours at different places is to be measured. Daily peak hours of sunlight are likely to vary between places. These hours can be considered to be the annual daily average. Hence, a place like Maine having 4 hours average of daily peak sunlight-hours may have 2-3 hours of daily-peak sunlight-hours on an average in winter. While in summer, it will have 5-6 hours.

Can solar cells work effectively at low temperatures？

The fact is solar cells are not known to function to its open in extremely hot temperatures. Commercial solar panels get tested at 77°F temperatures. If hotter than this, then their performance starts to deteriorate. The reason is all electronic equipment, be it big or small prefers cold and cool temperatures. The same applies for solar street lights. Hence, cold temperatures are unlikely to impair their overall performance. Hence, you may consider investing in Solar street light to protect your property.
