A solar panel flat mounted should produce 50% of its max power output when the sun is something like 27 degrees above the horizon. If you aren't getting anything when your panels are flat, then you have something wrong.

I am going to use multiple mppt controllers to counter shading losses. It isn’t that much more expensive to have small controllers for each panel over one large one.

You are only going to see close to 100% when on the sun path.

I have been leaning that way as well. I decided to have a shower area and just hang a closet organizer in the show when not in use. Then just swing the closet organizer out of the way when I need to take a shower.

Yes, I have 800W of Solar on my TT. Ok, so 40A comes out to around 576W of solar, and you have 630W of panels. That is 91%

Are you running down the batteries enough that they can take a full days charge?

The Quattro is more expensive than the multiplus as they not only allow charging from the grid, they also allow charging from a generator and have an automatic transfer switch. Not that I plan to have a generator, but I’d rather have the option than not. And I will be using electric for...

It is a figure of speech.

70% is based on a flat panel and full sun exposure. I didn't think I needed to explain that.

How are you measuring that?

what is your point? Are you somehow offended that I am comparing it to an Earthroamer? Are you offended that I am doing the work myself?

Considering an Earth Roamer is three times as much, this build will be cheap. And I will be doing the mechanical work myself. The electrical system alone will be around $24000. And this will be my full time home.

Yeah, I thought about that. But I don't have a garage, so I will be renting one, and easier to do it all now, especially considering I will be living in it full time. Also, there will be days where even 4800W won't be enough. I get my numbers from real world experience which aligns with the...

The average a flat panel will produce during the day in the winter is around 70%. That means during a 12 hour day, 1kW of panels will produce 8.4kWh. So, 4kW will produce 33.6kWh. Overcast will reduce that by 75% which is 8.4kWh. This will likely be more than a enough to keep the camper warm in...

Mostly in the boonies full time. And I want as much solar as I can get because I want to eventually place this camper on an electric F550 when they decide to make one. My whole goal is to be able to charge the battery up over several weeks and then move to a new location. I am sure I will park...

We have similar goals. I want this camper to last me for the rest of my life as well. I already have 20kWh in batteries, so if I can get similar modules, I will double that capacity. But waiting as long as possible means I hopefully pay less. What batteries are you using?

Can the roof be walked on?

Hi Andreas, If you recommend that solar panels be glued, then why do you also recommend keeping the color white? It seems to me that black glued solar panels would generate the same heat problem as a colored box would. Can the roof handle a 600 pound distributed load?

A 50kW brushless DC generator at 48V would require wires capable of carrying 1,000A for around 25 feet. That is over 1 inch thick wire. Plus I will still need a battery charger that will cost several thousands. Solar panels on a flat surface are about 80%-85% efficient on average in summer...
