Installing Solar Panels on my 2016 32BHDS Need suggestions

Hey everyone,
I am In stalling Solar Panels on my 2016 32BHDS and need suggestions for location and how many panels, how many watts do I need, do I really need 2 batteries or is one ok?

I bought the Renogy 100 Watts 12 Volts Monocrystalline Solar Starter Kit
Have any of you guys used this kit?

It comes with a 30 amp solar charger. I hope its reliable.
Due to the set up of my camper it may be hard to install the charge controller close to the batteries, will using larger gauge wire decrease the lose going from the controller to the battery and if so what gauge would you use?

Thanks for any input you guys can offer.

Several JOF members are using Renogy panels, including me.

The size of the solar panel and the number of batteries are related to one another.

For example:

'
If you have 1 12 volt battery, let's say an 80 amp hour battery, you should generally only be draining that by 50% ( to prevent damage to the cells )

So if you use 40 amps overnight, then you need to be able to put 40 amps back in the next day

The renogy panel produces 100 watts at an optimal 19 volts which is converted down by the controller to a charge voltage of approx 14.8 volts

100 watts / 14.8 volts = 6.75 amps per hour.

On a average day, you should expect about 6 solid hours of optimum sun and charging , or about 40 amps of charge capacity

There you go..... 100 watts can manage a single 80 amp hour battery based on proper use.

Two batteries would allow you to have 80 amps of power over night, but you wont have the ability to recharge them unless to expand the wattage of the solar panels

Having more batteries is OK also, in case you have a rainy day for example, but your ability to fully recharge is limited to the wattage of the solar panel

I would really try to get the controller as close to battery as possible.

Voltage is lost over wire lenght.... this is one reason why the solar panels start at 19 volts, to allow for the voltage loss of the cable run from the roof down to the power room.

The charge voltage from the controller is already reduce to 14.8volts. You don't have much room for loss in this critical voltage total to the battery.

So do I need to turn the solar power off when connected to shore power?

No you leave the SOLAR connected. It will work with the TT's battery charge controller.

So I'm buying a solar ready Jayco, what do I need to buy? Panels only or a sole kit?
Also is it better to mount panels or get the portable ones?
