This kit comes with three 18.35% high-efficiency 100W Eclipse solar panels made of quality SunPower cells. For comparison, regular mono/poly panels have around 15% efficiency. The panel is coated with thick, anti-reflective, high-transparency iron-tempered glass. The 40 A Commander MPPT charge controller brings the peak conversion efficiency of 98%. You'd also get a tracer meter that gives a full control over the charge controller. The package includes an MC4 inline fuse and ANL fuse components for charge controller and battery protection.
