If you installed an off grid solar system, you can approximate that, based on the average amount of sunlight you receive, the system would reduce about half of your monthly electric bill. The initial investment will save approximately half of the monthly bill for the life of your solar panel system.
Off grid solar systems are great for those who live in remote locations where bringing in the electric grid is extremely expensive or inconvenient, or blackout happens frequently or for those who prefer to not have a monthly electric bill at all.
A DC-AC inverter will transform the DC power from your solar power system into AC power that is useable right through your power outlets. A good, high-efficiency DC-AC inverter can make or break the performance and cost-effectiveness of an off grid solar system
