The answer depends! The cost is tied to the size of your system, your energy use, and whether you include batteries for storage. Because every property is unique, we design each system to fit your specific needs and budget.
With proper design and installation, modern off-grid systems will provide consistent, dependable power even in remote locations. Your choice of solar contractor is also important, as you would be wise to choose a company that specializes in off-grid and provides a LIFETIME Craftsmanship Warranty to stand by your system “after the last check is written”.
Yes, but why would you want to? Switching back is possible, but may require adjustments and/or added equipment. In some events, you may have to pay to pull grid power if it did not exist previously. If you are unsure, it is better to start with a hybrid system (Solar & Grid-Tie backup) and track the actual production/consumption data (utility bill) to determine what you need to add to your existing solar system, if you decide to go off-grid in the future.
