Mornin gang, I have been absent for a while too busy updating my latest RV. While I don't currently own a good "old" RV (its a 2006) that's all I had for like 40 years lol so I feel right at home here.


 So, we do a lot of dry camping and in my last RV I had 400 watts or solar which kept my four deep cycle 6 volt golf cart batteries well charged. However, in my latest 2006 29 ft, Class I initially installed 470 flat rooftop solar watts (with four Trojan T-105's, 450 total Amp Hours) and again I got by fine powering a small Haier dorm size 120 VAC aux fridge 24/7 via my 2KW PSW Inverter plus the normal LED lights and vent fans and water pump etc.        BUTTTTTTTTTTTTT   when we dry camp in warmer climates if we park in the sun, sure my 470 watts took me up to near 100% SOC most of the daylight hours, HOWEVER it stays much cooler if we park in the shade but then you don't harvest as much solar energy WELL DUH.  

 THEREFORE I went and added yet another 245 watts taking me up to 715 total solar panel watts. So far with that even if parked in shade on a sunny day I can achieve 100% SOC in the day yayyyyyyyyyyyyyyyyy Even when parked under roof in my pole barn lean to addition I still get enough charge to keep her at 100% SOC on sunny days (that's no load but phantom draws of course)

 As far as expense if you do all the work yourself its not really that bad, here is an estimate of my installation cost. I say estimate, I done forgot some of the exact costs, bought on Amazon & Flea Bay but the panels locally from an Amish store

715 Solar watts at 90 cents per watt =  $644  Three 24/30 volt panels approx. 39" x 64"

50 amp Sun MPPT Smart 4 Stage (Bulk, Absorb, Float, Equalize) Solar Charge controller  $270

80 Amp PD 9280 Smart 4 Stage (Bulk, Absorb, Float, Equalize) Charger   $280

2000 Watt Pure Sine Wave (PSW) Inverter  $300

Four Trojan T-105 6 Volt Golf Cart Batteries $500                  TOTAL COST  $1994

 We have a 4 KW Generator which we might use for morning coffee and wife's hair dryer and microwave etc. I don't like such heavy loads sucking off my stored battery energy

  We just love the freedom and cost savings from dry camping in the Utah and Colorado mountains on BLM and Natl Forest and Wildlife Management type areas, BUT to do so long term (we may stay a week at a time) you gotta have Solar SUBJECT TO THE LIFESTYLE AND CREATURE COMFORTS WE DEMAND you can obviously dry camp with no solar (or much less then we have)  whatsoever, but this is our personal choice of comfort and living.

 Best wishes n God Bless
