Installing 440 watts of solar panels on the roof. Not much real estate left. Now I need to find a big electric motor and I will have a hybrid.

Gary I am looking to do the same but with all the ham antennas I have up there, I have even less real estate to use than you.

Is that 4- 110 watt panels? So how many have you got up there all together? I have 2-110 watt panels and a 15 watt.

8 x 55 watts = 440

Hmm Maybe I should start using my ham license. Got a tech a few years ago and have never been on the air. Maybe time to go for a general

This past winter I rewired my panels. They were wired in parallel and provided 17vdc at high noon and less the rest of the day. Rewired in series/parallel and now get 34vdc and almost 17vdc at dusk. This means the batteries start getting a charge at sunup and continue until sundown. Have even seen charging during a full moon and cloud covered day.

In order to do this you must use a MPPT controller. This takes the higher VDC and outputs the proper voltage to the batteries. The controller I use will take up to 96vdc input. I wired 4 + 4 for 34vdc. Could have rewired 2 x 2 x 2 x 2 for a 64vdc input. The higher the voltage the smaller the wire needs to be.

The panels are older 55watt panels that I owned. We can go without generator usage thru the use of our 2500 watt pure sine wave inverter. Have two golf cart batteries now, but next batteries will be lithium-ion.

I have changed to a lithium 100AH to continue this subject. We can usually do one day on one charge, but planning on a second 100Ah and also have 200 more watts of panels in the garage. Will wire them in series with those I have to give me 51 volts off the roof.

I haven't but have seen some full time boondockers with solar sides. The ones I have seen were on small RVs (under 25').
