Solar Power Light

Solar Power Light

How many days of sun light does it take to power one street light?


i am writing a letter to congress to tell them they should make all street light solar powered

A typical street light might be 250 watts. A solar panel might collect 25 watts per square meter. When you consider clouds in most places half the time, you would need 10 square meters of solar panel to run one street light. Then there is all the energy needed to make the solar panels, and install them.

So the answer is: 182 days of sunlight, and a BIG solar panel, to power one street light for one year.

Wouldn't it be better to put all the solar panels in one place? A 1 km x 1 km solar panel is 100,000 times bigger than a 10 square meter panel, but it costs less than 100,000 times to make and operate. Then you could run wires to bring the electricity to each street light. Oh wait -- the street lights ALREADY have wires to bring electricity to them.

And with one big panel, you could put it in Arizona, where there is more sunlight and fewer clouds. It has been figured that a 100 x 100 mile solar "farm" could provide most of the power for the US.

About Amorphous Solar Power Amorphous solar panels are created by spraying silicon on to glass in very thin layers, and are commonly known as thin film solar panels. This process allows them to be better at generating electricity in all lighting conditions, including cloudy or shady environments. Sunforce amorphous solar panels are weatherproof and suitable for outdoor use. They have a maximum operating temperature range of -40 to 176-degrees Fahrenheit, require virtually no maintenance, and are also effective on cloudy days. They can even withstand impacts from one-inch hailstones at 50 miles-per-hour. Solar panels convert sunlight into an electric current, they do not store power. Sunforce Solar Charging Kits are primarily used to recharge 12-Volt batteries (not included), which store and provide usable power. The included 200-Watt power inverter allows you to use traditional 110-Volt appliances with this system. The included Sunforce 7-Amp Solar Charge Controller must be installed to prevent any connected batteries from overcharging. Once fully charged, it is normal for the charge controller LED to turn off and on as the battery voltage fluctuates from the discharge/recharge cycle.

  • Amorphous solar charging kit provides up to 60-Watts of clean, free, renewable power
  • Designed for RVs, cabins, homes, boats, back-up and remote power use, and more
