​For a ~$3.158 million investment (historical grant and project funding levels cited for portions of the microgrid, including battery/storage components), the pure energy savings payback is extremely long—around 144 years ($3.158M ÷ $22k). This doesn't account for loan interest (if any), ongoing maintenance, labor, insurance, battery degradation (batteries typically last 10–15 years), or panel efficiency losses over time. Equipment like batteries won't last anywhere near that long, making this an incredibly poor business decision!
