【简答题】
Our off-the-grid system consists of eight solar panels (1,000 watts) that are mounted on a sun tracker rack. We also have a wind turbine that generates 3,000 watts in 24 mph winds. The energy generated by the wind and sun is stored in 16 6v golf cart batteries. We also have two 2,500-gallon above-ground water tanks and a 250-gallon propane tank. Every weekend, we haul two 275-gallon water tanks to the nearby town of Yucca and fill them with water, which we then pump into our big water tanks.
