Carlos, must be back in the day technology, no need for dumps or heaters etc to use up solar power anymore. Solar controller just opens circuit. No voltage, no current, no heat. I have 1500 watts, and even when batteries are only taking 10 or 20 watts, have no need to dissipate extra power.

And no power.  Also unacceptable.  The only other source of power is bringing in propane with a helicopter.  But I don't know the details, as I didn't install it.  I'm just a good troubleshooter.  Even if I don't know the product, I can usually find the problems.

I am impressed Carlos, not sure how it relates to solar power.

The closer you get the panels to facing the sun, the more power they make.  I'm not sure by how much, though.  Also, will you want to get up there and tilt them to face the sun every time?  

On our Class A install the installer pointed out that the sun moves from east to west. If you tilt your panels to the south you get more solar from the hit BUT it takes longer for the sun to hit and it ends sooner because you are not getting as much of the east/west ends as you do if the panels are laying flat. We choose to never have to go up on the roof to tilt ours.

I  have just under 1000 watts on the roof of my 35' Solitude 5th wheel, run through an MPPT controller and a 3000 watt/120 amp inverter/charger to 3 Lithium Ion batteries.  Specifically there are 3 320 watt panels which ran $194 each.  The panels are 60" X 40" each.  I'm boondocking in the Anza Borrego desert on a lightly overcast day and at 10:00 a.m. the panels are putting out over 30 amps at 13.5 volts, which allows me to run the inverter and still have about 20 amps going into the batteries.  Voltage at the panels is currently (no pun intended) at just over 94 volts.  I've recorded over 70 amps going into the batteries on a clear day.  

I boondock about 80% of the time, and although I've only had the solar set up since early December, I've run my genset for a total of 1 hour in that time.  We'll see what happens when I get into some rainy climates this summer.

3 120 watt panels?

94 volts out of of three 120 watt panels?

Wait what??  None of those numbers add up.  Or are even close.  

13.5*30=405

120*3=360

Neither of which is "just under 1000 watts."

A single 60x40 panel is around 300 watts.

I would suggest reading handy bob.com. Very good informative read. Afterwards you may not be an expert but will have a very good understanding of solar systems.  Jack myer has some very good info also.

This is really getting off-topic.  The OP meant 100w; not 1000.

Thanks. I tried to post that info but people are staying on the 1000. My mistake. Sorry.

You also need to be careful not to draw your batteries down too low, a good monitor is worth the $$. Too low depends on the type of battery you have, wet cell or AGM. Continue to educate yourself about solar for the RV, come back and ask all the questions you want and once you know what you really want to power give AM Solar and RV Solar Electric a call and talk to them. Just more of your education.

I contacted AM Solar and received a bid of 7500.00 for 340 W and the batteries, inverter etc. seems high to me but I am still getting quotes and want to go to a reputable person. Thanks for your suggestions.

How many batteries and what type? How big if an inverter? That seems ridiculously high.

2 ZS 170 Solar Panel Kit with rockers 325.00

1 Victron Phoenix MPPT 30A               474.00

1 Victron Phoenix invertor kit               550.00

1 45 A  shore power charger kit (AGM) 550.00

29 hours labor at 130.00 hour 

That is the breakdown.

Usually I just bring up politics, gun control, or religion, and the subject changes itself!

But seriously, just click the "edit" button at the bottom of the original (first) post, then click into the subject field and type as usual.
