My utility bills are very high, and I want to switch to off-grid solar power to save money, how much money can I save?
You likely will not save any money. A solar and off-grid electrical system designed to be large enough to off-set high utility bills would be prohibitively expensive. Reducing your energy consumption is the single most effective way to lower utility bills. The typical off-grid home uses well under 10 kW/h of power per day. If your consumption can be reduced to that level you are a good candidate for an independent electrical system.
