Remote off grid cabin system
Hi everyone, first time posting, though I've been creeping around here awhile,and I'm looking for opinions on putting together a solar system for my off grid cabin. I think this site and Midnite Solar's are about the most informative ones I've come across. I currently run everything off of my Yamaha EF2400iS. Once I started to research the subject I realized how complex a topic it can be (huge understatement). What I read over and over was that first I must know my loads, so I got a Kill-A-Watt meter and began to track my power use. I separated my larger loads- electric kettle, toaster and microwave, as I don't expect to run those items on my solar system. My main loads are TV, satellite receiver, stereo, lights and a couple other small items. The period of time I tracked my loads ran from Feb 16th- July 28th, a total of 162 days. In that time I was at the cabin on 55 days. In that 55 days we used a total of 14.05 KWH, an average of .255 KWH per day. In that 55 days there were 9 days that we stayed overnight. Overnight stays averaged .72 KWH. My work schedule has me out of town 14 days at a time followed by 14 days off, so there is usually no one there for 2 weeks at a time, and when I'm home I go there often. I'm kind of struggling trying to figure out how to size the system as it sees intermittent use year round, but not really very large power needs. I have read here many times that loads tend to grow, what I see happening in my case is that the cabin may be used more often, but with similar loads as now. I am near Thunder Bay Ontario, Canada. PVWATTS says I get average 4.62 solar radiation for the year. Thank you for your input!!
