Joe Prepper and the Most Common Solar Mistake


Watch Joe Prepper as he buys a solar generator for emergency backup.  Poor Joe hasn’t watched our solar boot camp videos and falls victim to the most common mistake in choosing a solar generator.
Can you guess what it is?

    Hi Marie,

    His mistake was that he purchased a generator with a battery size only large enough to run his fridge for 1 day. This would have worked if the weather was perfect (the solar panels would have charged them back up during the day). But since you can’t always count on sunny weather (especially when the power goes out), you should size your system to run at least 3 days without sun, and 5 days is even better.

    I don’t know. What was his mistake?
