Quick Answer
When conducting an off-grid home inspection, include essential components such as solar panels, water storage tanks, septic systems, and backup power sources, in addition to structural integrity and electrical systems. Inspect for proper installation, maintenance, and age of equipment. Verify compliance with local building codes and regulations.
Essential Systems
Inspect the solar panel array, ensuring it is properly sized for the home’s energy needs, with a minimum of 5-7 kilowatts for a typical 2,000 square foot off-grid home. Verify the inverter’s type and efficiency, such as a microinverter or string inverter with a 98% efficiency rating. Check the battery bank’s capacity, aiming for at least 20 kilowatt-hours (kWh) for a small off-grid home.
Water Collection and Storage
Verify the roof’s collection area, ensuring it’s at least 1,000 square feet for a 5-gallon-per-minute (GPM) water flow rate. Inspect the rainwater tank’s size and condition, aiming for a minimum 1,000-gallon capacity. Check the tank’s overflow valve, ensuring it’s set to direct excess water to a designated area. Test the first flush device and ensure it’s functioning correctly.
Backup Power and Safety
Inspect the backup generator, ensuring it’s properly sized, maintained, and connected to the electrical panel. Verify the installation of a transfer switch and automatic transfer switch (ATS) for seamless power switchover. Test the generator and ATS to ensure they’re functioning correctly. Check the electrical panel for proper labeling and grounding.
