While off-grid, a 50 watt solar panel is connected to my "house" battery.  

Boondocking and Solar Power

I prefer dry camping (boon docking).  I like the solitude of Forest Service, BLM and other open spaces. A few weeks ago I towed my rig from it's winter home in Southern Utah to some beautiful land in Southwest Colorado.  At this location I have amazing views of the West Side of the La Plata Mountains, horses to hang out with, and a wood shop and art studio.  I use my camper dining table for making art, but while at this location I can also build in my shop and paint with oils too.

Running power tools 

I have no power at many locations, while camping I keep my batteries fully charged with a 50 watt solar panel.  It's very sunny here in the Southwest, so solar is the way to go.

While woodworking in the shop, I use my cordless power tools and charge up my batteries using a small inverter plugged into my jeep lighter, or I bring fully charged batteries.  I have a cordless skill saw, and cordless drills. But I need more.

As I looked at the process of converting my shop to solar, and to keep it simple, I searched for  a usage chart online to get some idea of the size of the Power inverter I would need for most of my tools.  Initially, I plan to power up my batteries for cordless work, light up the studio with a few CF bulbs, run my small iPod stereo speakers and power tools.

I learned that smaller tools like sanders, drills, and jig saws don't draw a lot of continuous power, they surge when they start.  Other tools like my chop saw and table saw draw more power and surge on start too, and will have to wait for a bigger inverter.

For less than $100. I ordered the Power Bright Inverter from Amazon prime.  I thought I'd get started with the 1100/2200 inverter and upgrade to the Powerbright 2300 next year.  I will need the bigger inverter for the big saws and welding.

The setup includes:

1. 50 watt panel and 35 watt panel, parallel connection if needed.  I will start with the 50.
2. 12volt deep cycle marine battery (just like our RV battery)
3. 30 amp charge controller
4. 1100/2200 Power inverter - Powerbright PW1100 (Modified Sine Wave)

What will I use this power for?

Lights (compact fluorescent)

Music (iPhone stereo speakers)

Chop Saw

Table Saw

Bisquit joiner

Palm sander

Orbital sander

Angle Grinder

Jig Saw

more

1. The inverter will be connected to 12v DC battery (deep cycle)
2. The inverter will supply 110v to tools, light, etc
3. The solar panel will keep the battery charged
4. The charge controller will shut down the power coming from the panels to avoid overload.

There are many helpful sites online and youtube videos to show how simply I can power my shop.

Solar Power for Camping, Hiking and Photo Gear

I live simply, and when camping do the same.  I'm not one to watch TV at night at home or while traveling. I tend to watch the night sky and do a bit of reading or art-making while camping. I do watch movies at home, but prefer the quiet of camping and my connection to the land and universe.  On a cold night I light a fire and enjoy friends and family at camp.

When dry camping, I like to keep my 12V house battery charged for lights and to run the water pump and toilet.  I bought a 50 watt and a 35 watt solar panel.  The 50 watt panel came with a kit that includes a 12V backup battery for traveling and to charge AC devices. I have not needed the 50 watt for my limited power needs in my Saturn.  All of my interior and exterior lights are LEDs so they use very little juice. I turn off the water pump when not in use.

At Wahweap campground,  a 35 Watt Solar Panel is hooked up
to trickle charge my rig when dry camping.  It's often sunny out here
in the Southwest, so solar is the way to go.

Boondocking in Utah, my solar panel has kept my 18 footer fully charged
for a week of camping.  When I unhook and go for a backcountry 4WD,
I disconnect the panel and take it with me, for emergency power.

Since taking this photo in the fall, I've removed the awning as it was torn, and had a lot of mold when unrolled.  I will replace it.

While dry camping (boon docking) in Colorado, I kept my battery charged
by solar trickle charge.

Solar Power for Hiking and Backpacking

I am a photographer, and carry lots of camera gear while hiking.  Digital cameras eat batteries for lunch, so it's important to be able to keep the batteries charged in the field.  On a recent 5 day backpack, I tested a few solutions to battery use. One solution was to carry 3 dedicated Nikon batteries for my D5100 (my lightest weight camera body); another idea was to use the Goal Zero to charge the AA batteries for use in my point and shoot over the 5 day trip.  Here are some suggestions to increase the battery power when recharging at home is not an option.

• Try to limit the amount of "chimping", reviewing every photo. (any monkey can do that)
• When shooting video, which requires the use of the LCD, don't review when finished recording
• Weigh the difference between carrying extra batteries for your cameras, or re-charging in the field

What I learned was that for 5 days of photography, including video recording, I need an additional dedicated Nikon battery, which only weighs a few ounces.  But since I also carry and use an iPad, I like the Goal Zero system for charging batteries and devices in the field.

I bought the Goal Zero Solar Panel/Charger.  It charges 4 AA batteries using the sun in a short 2 hours.  Once charged I can use the device to charge up more AAs or directly charge my iPad or iPhone through the USB port located on the battery pack.  I don't mind the extra 1.2 lbs and can charge AA and AAA. 

The battery pack has inputs for the solar panels and USB devices.
It includes an LED light that runs for 120 hours.

The Goal Zero Guide 10 Plus Solar Kit, weighs just 1.2 lbs and sells for around $80. at Amazon
Here's how it works, hang the Goal Zero Panel on your daypack or camera bag, and hook up
 the battery pack. The panel will charge the battery pack in 2 hours.
Connect your USB device to the battery pack and charge
your iPhone, iPad or digital camera.
