There's nothing magically different from one type of shade to another.

The distances are obviously different, and how much light actually passes through/between leaves and clouds varies, but both are blocking some percentage of the light that would otherwise hit the panel.

I spent some time on Solar Bob's web site last night. Ha ha. I love reading that guys perspective. Lots of first hand knowledge for sure.

I don't know if I'm going to go the solar route, but after reading all this stuff, it really has me interested in trying it out.

My biggest take away from reading his site it, there seems to be a big disagreement on what a fully charged battery is. Bob doesn't think many widely accepted methods for battery charging are working. I read enough to make me want to test/monitor my battery to see what it's really doing. Ya think you are taking care of your battery, but maybe I'm not taking care of it at all...?

I've got a new rig coming next month. I'm definitely going to get a battery monitor to get better informed about that. We'll see where the solar thing goes.

Has anyone noticed their stock converters not fully charging their batteries (12.7v)? I guess batteries can differ, but in Bob's example, Trojan's want 14.8 volts to charge a 12v battery.

Anyone have experience with measuring the charge going to their batteries?

The "Solar Ready" on the soon to be New Jayco started me down this path, Handy Bob helped me realize it was a reasonable thought, along with all the other stuff I read here and elsewhere. We camp in National Parks allot, and the thought of the panels doing the work to charge batteries while we are hiking, enjoying nature etc, sounds awesome!! Generator only got microwave, and the occasional air conditioning if it's unbearable out.

I want to start buying parts, but realize that I need to get the camper first. Need to know what the solar ready wiring lengths are to get an idea of loss. Need open roof measurements to get a good idea of real estate for panels and see where batteries will fit and what size.

As much as I want to jump, I need to wait to get it designed.

I'd be curious to hear how current converters do at charging as well.

I bought my battery monitor first. The thinking behind it was that I needed to know what my power consumption habits were before sizing a system and batteries to match. I bought the Victron 600, since superseded by the 700. Gives you battery voltage, charge rate, % charge, AH consumed and much more. Programmable to battery type and size.

Just found this thread and read thru it all. I've also read HB's site.

Before leaving for the winter I installed 4x 6v AGM, 2kw PSW inverter and a custom monitoring system. I'm charging with a 2kw genny this winter and monitoring usage.

If I only run the fridge on propane and some LED lights I use about 15AH overnight. I run the genny thru the onboard charge controller to recharge for this winter. It hits the 90% charge level pretty quickly so it doesn't seem to be the most efficient way to charge.

As I type this the genny has been on for about 45min and the controller is at 13.42v & 7.1A into the batteries and has replaced 5AH.

I plan to use 24v residential panels with MPPT as in my area they provide the best Watt/$ & Watt/sqft.

Interesting discussion so far. I am another one of Handy Bob's followers and perhaps I put too much faith into his rants and teachings, but I think there is a lot of good info there. He has certainly tested out a lot of equipment and is living with solar. He is not a weekend warrior.

I followed his recommendations and installed 300W of "12v" panels with a PWM controller and I have turned off my converter at the breaker and haven't turned it back on. I would much rather have my solar controller maintain my batteries. I have not needed to turn the converter back on either (one camping season so far). I think the lowest my batteries have gotten is around 84% after a cloudy, rainy day where they didn't get much charge put back in. Usually they reach 100% each day before the sun sets.

Keeping in mind I am in Canada and things differ in costs I did a cost comparison of going MPPT vs PWM and I found the savings from the high voltage panels start to outweigh the cost of the MPPT controller at around 700Watts worth of panels. I was only planning on 300W to start with and that combined with the minor gains of MPPT over PWM made me decide on PWM. On top of that I am cheap so a $160 controller (SC-2030) was much more attractive than $400+ for MPPT.

I did the generator in the morning and afternoon thing for a season and have concluded that the generator and truck charging did not ever give me a full charge. Even the onboard converter did not unless I was plugged in for days. We had a new group 27 battery that would get run flat (12volts) after a night running the furnace. With my setup now and the battery monitor I know that I only use up around 20AH a night if that. Closer to 10-15 on average. Certainly not enough to drain a 120AH group 27 battery that was fully charged.

My solar install and details can be found here....

I am very happy with everything. I would also suggest as someone else did to install a battery monitor. It is the best addition to our trailer so far followed by the solar.

Happy camping!

I love solar threads! More people need to realize how efficient and effective solar can be. I was amazed that 300Watts was more than enough for us. I am trying to convince my neighbor to get a system for his new trailer.

I have a signature system core from AMsolar.com paired with two 6 volt golf cart batteries. The system I put together has two 160 watt panels with the blue sky 25amp controller. The wiring they provide is perfect for the system. I highly recommend a battery monitor with any system you get. My system works very well. My batteries are usually charged up by noon. Now, you need to remember that every ones needs are different. We just use lights, water pump and furnace at night. We don't sit in the trailer all day watching tv and running heat. I punched a hole in the roof of my brand new 26BHS the first week I had it and mounted a combiner box on top of it.. Just seal it up with Dicor and you won't have any problems. Good luck.

One other thing I forgot to mention. Someone mentioned PWM aren't efficient or capable when shaded or in the morning in low light scenarios.
We returned from a trip one rainy night (home in the dark) with around 90% charge on the batteries and went inside.
I noticed in the morning (sun was still very low on the horizon) that we were fully charged. Then I realized we parked under a street light! The street light charged our batteries over night. Pretty cool!

Don't tell the city or they will figure a way of charging you for the city light fixture lumens used for personal use. Watch the Panel output on a crystal clear night with a full moon above. Yes, there is a little charging taking place. I had to look twice when I saw it.

Another question that crossed my mind that I haven't seen an answer for:

Considering a 12V nominal panel, does it always produce a constant voltage, or does it ramp up to the maximum with increasing sun strength starting at zero and going up to the maximum?

I'm wondering, if the voltage does vary, if that gives higher voltage panels a step up, by getting to a high enough voltage earlier in the day?
