Robert, I totally agree, unless local laws and tariffs make solar unattractive by paying pennies on the dollar. If you have the RV stored near your home and you can fit a decent size battery bank in the RV, think "Nissan Leaf pack re-packaged into a size that fits in (for example) the box under a bunk bed, with the Leaf BMS included to keep the pack balanced and a 12V supply to keep everything running, then you can not only power the RV from the solar, but you can plug some of your house's loads into the RV power bank, similar to a mobile Tesla PowerWall. That way you *are* using most of the energy the RV solar is producing and it does not go to waste for the 50 weeks that the RV is parked. Just an idea, Cor.

That is either the grid with grid-tie, or a battery such as in an EV or RV. And an RV, unless it is used everyday, then the other 50 weeks of the year the solar is not doing anything because the batteries are always fully charged. So the ideal thing is to have a grid-tie house so that the 50 weeks a year the RV is at home, then you are getting full retail electric rates for every photon that hits them. And they are free power when you are traveling too. Without grid tie, none of these advantages accrue. So my recommendation is that if you have any sun at all anywhere on your propterty. BIGHT THE BULLET and contract for some minimum solar grid-tie system to get a trully approved GT system with NET METER. Then you can plug in your RV or extra solar panels and know that you will always get full retail value for the power everyday. If one has sun, it makes no sense not to go solar. Amortized costs will be less than half of the tens-of-thousands of dollars you will be paying the utility over the same time frame. I am always amazed that people will be willing to pay $200 a month for the rest of their lives, ($24,000 every ten years) but will balk at paying $24,000 once and getting a FREE $7,200 back from the IRA and FREE power for the rest of their lives (and no monthly utility fee except maybe the minimum $20 account fee)... It's a no brainer...

In Tucson and Phoenix, the utility companies are charging an extra fee if you have solar panels. By using a set of mobile solar panels, you may avoid these charges and numerous other regulations such as local permits. Need to check the regulations. I would bet that the "powers that be" have missed the use of mobile solar panels. ________________________________ From: EV <ev-boun...@lists.evdl.org> on behalf of Mike Scott via EV <ev@lists.evdl.org> Sent: Monday, September 25, 2017 9:27 PM To: Electric Vehicle Discussion List Cc: Mike Scott Subject: Re: [EVDL] Solar powered RV My little trailer has 800W on the roof and is grid tied while it's in the driveway.

Now I have a bank of DPST switches from the auto parts store so each panel can go the the charge controller or to the grid tie inverter. I'd sure like to find a circuit to selectively switch the panels over based on battery voltage... In summertime a 50W panel will fill the batts each day after I heat my coffee in the microwave. That's a second inverter that just takes 12V and makes 120VAC for the microwave. Had to use my EV battery cable making skills for the 1 or 2 AWG wires feeding that! Stand alone the loads are the microwave and refrigerator (10A almost continuously), plus LED lights, radio and a few fans, one of which is in the refrigerator vent and another is in the roof vent. Both those fans will come on if it gets too hot and on hot days it took about 100W to keep the batts up. Still hit 100 degrees inside. Time for new screens...
