Looking at a stand alone set up for freezer/ refrigerator . Another for back up water source. Another for home lighting, hot water controller" I gotta have a hot,hot hot shower every morning, or my back won't straighten out. Anyway I'm halfway to my goal of thirty panels , via purchasing two per month.

And if I can figure it our a stand alone furnace set up. That's 220 , I'm reading a couple books I got on amazon on the subject. No worries if I can't run the heater, I've got a decent amount of wood and a older fire place box in the house.

We are still purchasing one 100 pound propane bottle and filling it monthly. Kind of a hedge.

I like the redundancy, but that sounds like a LOT of extra work Dirk. Just my 2 cents, but have you considered a system with breaker where you can isolate different uses and turn them off.
I can't help but think God is up there right now saying "its time to shake the ol' Etch-A-Sketch and restart humanity again".

Actually, if you're getting 30 100-watt panels, breaking them up into several arrays is a good idea. Large amperage charge controllers are expensive, figure out the watt hours of the devices that you want to run and design each battery bank custom for each appliance. I would defintely go with a 24 or 48v system. Hopefully you haven't bought a bunch of 12v equipment yet, but if you have, it can be done. Definitely look at MPPT charge controllers so that you can put the panels in series and lower the amps through the wiring.

Guys, that's the problem I know just enough to be dangerous. I'm in the middle of two solar books on my kindle and think I'm starting to grasp it. I know it will be more work, but for me it makes sense to keep it basic and simple. I do not have 30 panels yet, that is the goal at two per month. I could go four per month but want to continue purchasing one 100 pound propane bottle and fill it per month aswell.

My goal is 30 100 watt solar panels and corresponding gear to make it work, and a redundant propane back up generator system. I'm trying to kill two birds with one stone. Ideally we want 10 to 15 100 pound propane tanks.

I made a HUGE blunder on the propane calculation, I was adding gallons, not pounds. Huge difference in terms of calculating long term usage in odd times. I thought I was going to,have 1000 to 1500 gallons , my mistake was that will be pounds of propane rather then gallons. A HUGE screw up.

Thanks guys.

Dirk, perhaps 30 solar panels is too many for starting your project. Thats a lot of panels and I never knew anyone who used more than 12 panels to run a house. Save your money, start out with 10 panels and if you need more you can always add to the array in the future. I ran my house on 10 panels and one single C-60 Trace charge controller hooked into 8 L-16 batteries. I'll admit that my electrical requirements were minimal, computer, TV, stereo, CB and radiophone and when the sunlight was hitting those panels we used the washing machine and hung the clothes up to dry. I used a Servel propane refrigerator and a propane water heater to lessen the electric power needed. Here are 2 pictures of my array, one before I added a rotating pole mount and the other, if you look behind the flowers you can see the back of 2 large panels sitting on the pole mount. Ten panels was too much and eventually I removed 2 panels from the house and set them up on my barn with 2 batteries and a smallerTrace C-40 charge control to power a 12 volt car stereo and a CB radio hardwired directly to the batteries. Do you live in a windy area? If so, look into a small wind powered generator. There are many new designs and the price has come down recently. They spin 24/7 in the right location and can help charge batteries in the winter months when those solar panels don't produce as well.

The thirty panels would not all be used initially . In my minds eye I see a need for spare panels, for replacement and perhaps other small projects. The fact of the matter is, I see food storage, lighting, water pumping, as separate. How many panels per project is not known yet.

The thirty panels are with the intent of having replacement panels, same size, same shape, simple to trade out with a panel, should one go bad.

A former acquaitence had solar on their roof and complained when a panel was damaged from hail. I would also be concerned about damage if living in a tornado or hurricane prone area. Not sure if this would work, but how about a protective housing for the panels under hurricane glass?

Just have a question In place of 30 -100 watt panels, why no go with 12 or 14, 225 or 250 watt panels, they take up less room far easier to mount from what I have found in my own array seem to preform better than the smaller watt panels require less wiring and all around less equipment and far cheaper to ship??
PREPPERS SAVE THE EXCUSES, IT'S NOT ABOUT HAVING TIME, IT'S ABOUT MAKING TIME, IF IT MATTERS YOU WILL HAVE TIME
Every one has priorities, different for each of us, main reasons most of us can not form a group that will last our priorities are all different so are you. REMEMBER, IF YOUR PREP PRIORITIES ARE LOWER THEN THE PEOPLE YOU CAN'T WORK WITH, THEY MIGHT MAKE IT AND YOU WON'T, DON'T BLAME THEM FOR NOT OFFERING YOU HELP LATER, WHEN YOU FAIL LATER AND YOUR IN TROUBLE. BLAME YOUR PRIORITIES.

Thanks man. Now I have another $200 piece of equipment on my "to buy" list. Darned Trimetric battery monitor. :) :(
For real, thanks though. Good reads!
