This is a system that has grown through the years. Bob has always expressed a desire to “walk his talk”. Decreasing his carbon footprint has remained his goal. The original photo is circa 1992 and was a battery backup system. Over the years more modules were added and integrated with the utility grid, while maintaining the battery back-up capabilities. The 4-year-old in the 1992 photo installed the system in the 2019 photo. Module efficiency has increased dramatically and costs have decreased. The modules in the original photo were 60 watt modules, whereas today, we regularly install 350 watt (and up) modules.
