Off-Grid Solar
Full off-grid PV systems for cabins, rural properties, and homes without utility access.
Off-grid solar means no utility connection: PV array + charge controllers + battery bank + inverter, plus often a backup generator. Sizing is harder than grid-tie because there's no utility to absorb shortfalls — designers build to worst-case winter production with 2–3 days of battery autonomy. Look for installers experienced specifically in off-grid; the design and component selection differ substantially from grid-tied work.

FAQ
What does a typical off-grid system cost?+
Small cabin systems (basic lights/fridge/water pump) start around $15,000. Full off-grid homes typically run $40,000–$90,000 installed, depending on climate (winter sun availability), battery bank size, and backup generator.
How big a battery bank do I need to go off-grid?+
Most off-grid designs target 2–3 days of autonomy. For a typical residential load (15–25 kWh/day) that's 30–60 kWh of usable battery storage — usually built from lithium iron phosphate (LiFePO4) cells.
