Solartech Power
These 36-cell modules have an output voltage that's well-suited for charging 12 Volt batteries and can be wired in series for charging 24 or 48 Volt battery banks with inexpensive PWM controllers (see Charge Controllers for more information).
These modules, from Solartech Power, are efficient and robust with tempered glass, tough polymer back sheets and anodized aluminum frames. The modules offered here are Listed to UL 1703 and FM-Listed for Class I/Div II requirements. The 20W and 30W modules have output cables (no connectors) while the larger modules feature diode-accessible junction boxes. Made in China.
