We have enjoyed our solar electric (photovoltaic) system for over a year now; long enough to have seen how it performs on a daily basis, and to note what demands we can place upon the system.
The system we installed in November of 2014 is an off-grid system with a battery bank for storage. We designed the system with, and purchased it from Backwoods Solar, an Idaho company that specializes in off-grid systems. Taking into account our budget and intended use, we decided to purchase three 290 watt solar panels, eight Trojan 6V batteries, and a high quality inverter that will allow us to expand our system as needed.
The system we purchased was intended to meet all of our needs most of the time. We knew from the start that there might be times that we would need to supplement with our generator (a Honda EU2000i). And that has proved to be the case on a few occasions.
