A small completely off-grid solar PV system was installed at Buford Middle School in 2014 to power the ventilation fans for the greenhouse. The system has 3 pole mounted solar PV panels totaling 390 watts attached to batteries with a storage capacity of 4,176 watts. The system powers the greenhouse’s two ventilation fans (16” 12v DC) and a small 375w DC to AC inverter to provide 120v AC for small additional loads (such as a laptop, radio, or cordless tool battery charger).
