When choosing the solar panel 300W you should look first at its photo elements. There are mainly two choices mono and poly crystalline cells. Although cells are same in quality will have different performance metrics. Poly-crystalline panel will be cheaper, but mono-crystalline will produce more energy. Then you need to decide what kind of system you want.

Once you decide on the system you can choose right equipment like, battery charger, string inverter or micro-inverter, switches and disconnects.
