Realistically, what can a 45 watt solar panel system be used for?
)
October 2nd, 2014
A national discount chain offers a 45 watt solar panel system for sale.
Some of the things they suggest can be done with it is charging your car battery, charging your laptop, providing electricity at a campsite and having an “off the grid” backup in case of a power outage.
So, what can actually be done with a 45 watt system? How much, or what, could you backup in an outage?
Is this a useful product or an expensive plaything?
