Review on 🌞 Portable BigBlue 100W Solar Panels - Waterproof Tempered Glass Solar Charger with Carry Suitcase, Aluminum Kickstands, and 5.2ft Anderson Connector for RV Battery and Generators by Mark Colbert

I was looking for solar panels that I could use to increase the solar charging capacity of my Ecoflow Delta power plant (max 65V DC, 10A). So I bought 4 of these with the intention of connecting 2 groups of 2 in series and then connecting those 2 groups in parallel. I wanted to use this setup to provide backup power during power outages. So basically I would install panels in my garden. The first thing you need to understand is that these solar panels have two Anderson connectors that supposedly allow you to connect 2 together in what is called a 'series'. However, if you connect two panels together using Anderson connectors, you are effectively connecting them in parallel (electrically). Both Anderson connectors connect to the same electrical assemblies and are therefore electrically equivalent. This corresponds to a parallel connection. Making the connections I want to make becomes "inconvenient" (although possible) with the Anderson connector. But while I was "chasing the sun" in my garden, I had to constantly move the panels. Moving 1 panel might be ok. Moving 4 panels seemed totally impractical to me. The Anderson connectors come loose easily, which is quite annoying. The manufacturer of this panel would save me a lot of headaches if they just put the MC4 connectors on top of the panel. from my supposed 400 watt configuration. This was in full sun with all 4 panels. That's about 54 watts per panel. When one of the panels was dimmed (even slightly) the power output dropped sharply to around 20-30 watts for all 4 panels. Maybe they didn't use enough bypass diodes? The legs of the stand are short and not adjustable. They are either open or closed. In the summer months, the stand can be long enough to tilt the panel at midday. But in all other cases you probably need to underlay something to get the best performance. The panels fold well and have a good quality semi-rigid surface. The weight is reasonable if you only have to make do with 1 or 2. If you need 3 or 4 to meet your performance goal, you are better off going with lighter, higher performance foldable panels. I ended up returning all four BigBlue 100W panels and paying slightly less (in total) for two lighter and handier Ecoflow 160W folding panels that seem to me to offer a comparable power output.
