The Sun is a relatively fixed object in space…it isn’t going anywhere

EXCERPT:

[My comments in brackets.]

Mr. Cody said users should be realistic about how much power portable solar panels could create.

“People who are starting from scratch don’t realize that solar panels don’t always put out a consistent stream of energy,” he said. “The sun comes and goes [no it doesn’t…the sun stays put and we revolve around it]. There’s a shadow that reduces the current flow [yes, that could be true].” As a result, Mr. Cody suggested using the devices to charge internal or external batteries [not necessary for a home connected to the utility grid, in which case the meter swings both ways], rather than to run electronics directly [this applies to this kind of portable solar-electricity]. “Here’s an analogy,” he said, likening a battery to a water storage tank. “You have a little water pump pumping a small, constant stream of water in a tank. Without that tank, you couldn’t have a shower.”

The occasional intermittence of these devices’ energy supply can be a drawback. But for some users, they are literally lifesavers. “We have lions and elephants nearby here,” said Martin J. Graber, a doctor and international development consultant who works in the Narok district of southwest Kenya. Dr. Graber uses a solar-powered lantern when he goes to the outhouse at night. “I want to make sure there are no animals.”

*Although, pretty cool potential to have electricity wherever you go on planet Earth because of the Sun.
