I&#8217;ve been RVing long enough now to know what I need in terms of a solar setup. Soon as I can free up the cash, I&#8217;ll be ready to spend!<\/p>\n<p>My battery bank is comprised of two 6 volt golf cart batteries with a capacity of about 200 amp hours. I only really get 60% of that capacity, so I have 120 amp hours available to me. By being frugal and only using power for the fridge, propane detector, and furnace, I can spend two to three nights off shore power. I can do three to four nights if I don&#8217;t have to heat. The 15 watt panel on the roof gives me about 4 amps a day, enough to recharge my laptop once a day when it&#8217;s sunny, so I don&#8217;t factor that into the equation.<\/p>\n<p>So, with strict energy consumption in mind, I average 40 amps per day at 12 volts. Having 60 amps available to me would mean not having to be so careful and give me a good buffer.<\/p>\n<p>Also, I have very little use for 120 volt power, except for computer charging. I don&#8217;t miss the microwave or toaster when I&#8217;m not plugged in, so I was hit with the realisation that I don&#8217;t need a whole house inverter! My little 400 watt inverter is more than enough for my needs. If I absolutely needed to print while boondocking, it&#8217;d be cheaper to just go have it done at a copy store. So, all I need is a solar panel and a regulator.<\/p>\n<p>I&#8217;d like to be able to boondock in the Yukon this summer for two weeks at a stretch, the length of time you can stay in a territorial park in a 28 day period. So, that meant I&#8217;d need a solar panel capable of providing me with 840 amps of power.<\/p>\n<p>This is the point in my calculations where someone came up to see what I was scribbling about. Turns out he knows solar (too funny, what a coincidence). He looked at my numbers and said &#8220;That&#8217;s an easy one. 125 watt panel and a regulator. Add two to six more 6 volts if you have the space and weight for them and you&#8217;ll never have to worry about power again.&#8221; I got a second opinion on that, and got the same answer. So, now I know what I need and I&#8217;m starting to accumulate quotes.<\/p>\n<p>I think I&#8217;ve given up on the generator. It&#8217;s surely a lost cause by now. I&#8217;d probably be better off having it removed and then using the extra carrying capacity for doubling, or even tripling, my battery bank. Three people also suggested that I might be able to get enough for the scrap generator to finance a good part of my solar investment. So, that&#8217;s another thing I&#8217;m going to be looking into.<\/p>\n<p>Investing in solar has been a long time coming, but I&#8217;m glad I waited because now I really know what I need and I can spend my money well.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve had solar on the brains for months.
