Should I do a grid-tie or off-grid solar PV system?

If you’re already tied to the electricity grid, or are in close proximity to power lines, we highly recommend a grid-tie system. The cost of battery storage today does not make financial sense for those that can connect to the grid, but we’re getting close! If you have requirements to have stable electricity, such as medical equipment, you may want to do a grid-tie system with a small battery bank back-up. If you have a home that is not already tied to the grid, such as a recreation cabin or RV, an off-grid system with a battery bank is your best bet.
