Cool or ridiculous: outdoor solar-powered laptop charging stations?

1 Answer

Answer :

It gives the appearance of being progressive and ecologically green. If you have a bad battery and/or AC power is unavailable for some reason, such as during a major power failure, it is worth it. For normal use, wall current is the way to go. A 40 Watt laptop will run for 10 days at 24 hours per day on $1.20 worth of electricity. If you use the laptop 8 hours per day that extends to $1.20 per month. or $14.40 per year. How much are they spending to buy, install and maintain the solar chargers? Do the math to get an engineering answer. (It is probably way more than 20x that.) I will leave it up to you to decide the marketing value.
