    <![CDATA[<strong>Author:</strong> <a href="https://www.rpod-owners.com/member_profile.asp?PF=8600" rel="nofollow">offgrid</a><br /><strong>Subject:</strong> 7366<br /><strong>Posted:</strong> 02 Oct 2018 at 7:59am<br /><br />I know this is an older thread but just to clear up some misconceptions on solar system design I see here I'd like to add a couple of comments.<div><br></div><div>First, a 100 (or 200 or whatever) watt solar module essentially never produces 100 (or 200) watts. Why?&nbsp; Because solar modules are tested at 25C (77F) in a flash tester in a conditioned factory at an irradiance of 1000 watts per meter squared, aka "1 sun". That is what is called STC (standard test conditions).&nbsp;</div><div><br></div><div>You can certainly get the 1000 w/m2 in the wild, perhaps a little more on a very sunny clear day with the solar module directly facing the sun. But, unless it is freezing out you won't get the 25C module temperature. The solar module will heat up in the sun and the output is reduced.&nbsp; On a 25C (77F) day the module will typically be at about 55C (131F) and output will be reduced by around 15%.&nbsp;</div><div><br></div><div>This reduction in output comes as reduced voltage, current output actually goes up just slightly. This is why modules designed for 12V battery charging typically have a max power voltage (Vmp on your data sheet) of around 17-18V, so they can still charge batteries effectively on hot days even though 13.6-14.4V is as high as you ever want to charge a lead acid battery.&nbsp;</div><div><br></div><div>An MPPT charger will not get around this voltage drop with temperature. That's just basic semiconductor device physics. The MPPT charger will only help with wasting extra solar module voltage you can't otherwise use, especially on cooler days.&nbsp; But if you're planning your system for summer use the 15% will be there even with an MPPT controller, and more for hot locations. If you're using a PWM controller, your losses are going to be more like 20% because of the wasted voltage.&nbsp;&nbsp;</div><div><br></div><div>The easiest way to determine what you can expect to get from a solar/battery system is to to look up the max power current (Imp on your data sheet), and multiply that by the sun hours for your location, time of year, and panel orientation.&nbsp; That will give you the average daily amp hours you can expect to get for your 12V electrical loads, barring any shading or dirt accumulation on your solar array. There is a nice calculator for sun hours here:</div><div><br></div><div>&nbsp;http://solarelectricityhandbook.com/solar-irradiance.html</div><div><br></div><div>Second, the energy available to your loads from the battery will be delivered at about 12V, even though the battery will charge at around 13.6V. So, you have an energy loss in the battery as well as the solar modules.&nbsp;</div><div><br></div><div>If you work in amp hours these losses will be taken into account but if you want to work in watts you'll need to derate your system for battery voltage losses by about 12/13.6 or about 12%. So, your total derates starting from solar module nameplate watts to delivered load watts will be around 25-30%, maybe more for a hotter climate.&nbsp;&nbsp;</div><div><br></div><div>None of this should stop you from going with solar, its so cheap now that nothing can compete with it as long as you have good solar access. Just be realistic about what you can expect to get from a given size solar/battery system.&nbsp;</div><div><br></div><div><br></div><div><br></div><div><br></div>]]>

I wouldn't need a charge controller since I've already got one big enough to handle another panel.<br /><br />I'd plan on having a cable of about 10'-20' to allow flexibility of where I placed it outside.  It would run through the port on the back of the pod.<br /><br />But, unless our style of camping changes significantly I don't see a need for it.<br /><br />]]>

It cost about $180 from Amazon.  <br /><br />I am using the most secure Velcro brand tape they sell and it is stuck to the trailer with USB tape.  I run the Velcro around the entire perimeter of the panel.<br /><br />First time out I also secured the panel through the front center grommet to the hitch with rope.  We had no issues travelling with it.<br /><br />Second time I was more confident of the ability of the Velcro and didn't use the tie down.  About 1/2 hour from home I saw the panel in my rear view mirror had blown off.<br /><br />So, I replaced the panel and have abandoned hopes of travelling with the panel outside.  Instead it rides inside the trailer behind the couch cushion.<br /><br />I can add a second panel if need be through the solar port at the back, but I don't expect that will ever be necessary.<br /><br />There were pictures of my installation on this site, but I believe they were all removed when they changed servers about a year ago.<br />]]>

The PWM controller on most installations is, at best, 90% efficient. If using portable solar you're guaranteed to have a 30' minimum (if using the builtin connection), and as much as 50' of small-ish gauge wire. So plan on 200W of portable panel being effectively 160-ish Watts, at the battery, of value.</div><div><br></div><div>With a fixed install you can install quite heavy gauge or 10'-15' length and use an MPPT controller and get about 96% efficiency at the battery, or ~192W out of 200W panels.&nbsp;</div><div><br></div><div>As you can see, solar is finicky, and there's a lot of factors against getting the published rating of any given setup. My personal mantra, going into solar, was to be happy with half. I installed 200W because 100W is good enough to keep me happy.</div>]]>

    <![CDATA[<strong>Author:</strong> <a href="https://www.rpod-owners.com/member_profile.asp?PF=3251" rel="nofollow">M0tl3y</a><br /><strong>Subject:</strong> 7366<br /><strong>Posted:</strong> 24 Feb 2016 at 3:08pm<br /><br />My opinion, with my fixed solar install, is that I'll still park in the best spot (shady or not) for my trailer and I'll deal with the lower sunlight levels. I believe it evens out, or is even better, in the long run to stick with fixed. My reasons are:<div><br></div><div>- Since I never put the panels away, they're always keeping the batteries charging, even if it's not optimal sunshine. I also don't have to hook up to shore power when I get home, or once-a-month in the off-season, to keep the batteries charged.</div><div>- I've talked with people that use portable and they get nervous about theft, so unless they're in camp, they usually hide them. I am usually doing something away from camp (hiking, site seeing, whatever) by 10AM until late afternoon (optimal sunshine time). It doesn't make sense to put them away during this time but, as people note, if you leave them out, you risk theft. I don't want to have to worry about it.</div><div>- To your point, most portable solar is in the 100W range because of size/weight convenience. With fixed solar you can easily have 200W, up to about 400W, on a R-pod roof, which compensates for indirect sunshine.</div><div>- My number one reason:I'm generally lazy overall. I just don't want to bother/worry about optimal sunshine and I want to come/go without the hassle when I camp. When I'm home, I don't have to plug in just to "top off the batteries". After I did my install, the charger/panels take care of the batteries for me.</div><div><br></div><div>A lot of this really depends on personal preference. Some people really like optimizing the sun hitting their panels, and for them, fixed solar would drive them nuts. For me, it drives me nuts to have something else to drag around camp, or worry about theft. To each his own.<img src="https://www.rpod-owners.com/smileys/smiley1.gif" border="0" alt="Smile" title="Smile" /></div><div><br></div>]]>

My main hang up is that the portable system will allow me to get the panel in some direct sunlight pretty much wherever I camp. I don't want to feel like I have to position or camp in a certain spot to get roof mounted panels in decent sunlight.&nbsp;</span><div><span style="font-size: 11px; line-height: 15.4px; : rgb251, 251, 253;"><br></span></div><div><span style="font-size: 11px; line-height: 15.4px; : rgb251, 251, 253;">If I went with a mounted system I would be looking at 300-360 watts on the roof, and probably doing the 24 volt wiring to the charge controller to help with voltage drop.&nbsp;</span></div><div><span style="font-size: 11px; line-height: 15.4px; : rgb251, 251, 253;"><br></span></div><div><span style="font-size: 11px; line-height: 15.4px; : rgb251, 251, 253;">If I went with a portable set up I would probably be limited to 80-140 watts due to storage and transportation alone.&nbsp;</span></div><div><span style="font-size: 11px; line-height: 15.4px; : rgb251, 251, 253;"><br></span></div><div><span style="font-size: 11px; line-height: 15.4px; : rgb251, 251, 253;">Can you tell me how your system handles in shady spots? Also, are your panels wired for 12 volt or 24 volt output to the charge controller?</span></div><div><span style="font-size: 11px; line-height: 15.4px; : rgb251, 251, 253;"><br></span></div><div><span style="font-size: 11px; line-height: 15.4px; : rgb251, 251, 253;">Also, maybe it is a wash with 80-140 watts (portable) in direct sunlight versus 300-360 watts (mounted) in partial shade sometimes? What are your thoughts?&nbsp;</span></div></div>]]>
