For example my E-Max electric scooter only uses 75 watts per mile. My daily commute is only 16 miles roundtrip. See E-max-scooter.com for details. So I need only 1200 watts per day. Now if I get 5 hours of sun a day I only need 240 watts of PV panels, if I could get 100% efficiency. PV panels do not produce as much as they are rated at and I will loose some in the charge - recharge process if the panels are on my home. Lets say that I buy 4 panels rated at 130 watts each. Total cost is 2800 dollars for the panels. Now add in the charge controller and some batteries, so maybe I spend 4,000 total. Not cheap, but it is a LOT less than the 50,000 quoted in the above article. This is a can do project with todays products right off the shelf. Kyle Dansie There are other ways to achieve this goal.
