Are backyard solar panels legit? I tested one, and here's how it saved me $30 a month

• The EcoFlow 125W bifacial solar panels cost $899 for a four-pack.
• They're portable panels that you can take with you or set up temporarily without construction, with easy setup, and lightweight construction
• Though portable, these bifacial solar panels feel very fragile, so they must be weighed down if conditions are windy; their low 125W input also limits their capacity.

I see more hurricanes in a year than I'd like, so I ensure my house is prepared to weather each storm and its potential consequences. We get a handful of power outages yearly, so I have a whole-home battery backup system and keep several portable batteries around the house. I also take these portable batteries when camping, so I was eager to test the EcoFlow 500W modular solar panel system. 

Also: This portable battery station can power your home for two weeks

There's a lot to like about ...
