SunPower is the most known manufacturer of solar panels in North America. The quality of solar panels is the highest among the other brands on the market. It’s less than 5 lbs and can be a reliable solar power source on your next adventure. SunPower panels are made of top-grade and high-efficiency solar cells, charging the battery banks faster than the other compatible modules. The panels are also designed for toughness, it is the only monocrystalline cell built on a solid copper base, which means it’s less likely to crack or break. The robust and efficient design makes this model stand out in the renewable energy market.
This panel can charge any 12V battery (LiFepO4, AGM, GEL, flooded lead-acid batteries).
Note: a charging rate depends on a few factors such as orientation, angle, and time/condition of a day. For example, on July noon, a panel pointed to the South (with no shade and clear sky) around the Toronto area can generate almost its full rated capacity (50W). That being said, a 100Ah 12V battery will be charging at about 4Amp after MPPT conversion (4A x 1 hour = 4Ah, which is 4% of the total battery capacity.
