Solar Options for Survival

I have recently been toying with the possibility of using solar power in emergency survival situations. There are several reasons for which I have entertained this idea. First conventional gasoline or diesel powered generators have a tendency to be extremely loud. This is a very undesirable trait when you want to maintain a low profile and not attract attention from marauding gangs. In such cases the quieter you can be the better you preserve your safety.

The second reason is that in the event of a major power disruption, with solar you will still have badly needed energy to recharge your cell phone or to use your computer. I keep thousands of survival books on an external multi-gig hard drive since you never can tell when you might need some of the contained knowledge. Solar power will enable me to access this drive when necessary.

My wife and I have an older RV which we keep at arm’s length just in case we lose power in our home. With the RV we have everything we need until such time as we revert back to our house once again to reside. We can cook in the camper, we have a safe place to sleep and heat and air conditioning at our disposal according to the season. One of my future projects is to compliment the on board generator with a solar powered version. I believe in redundancy so I would have the running at idle RV for power, the gasoline generator and solar provision to take care of us during a major emergency.

Another example of solar power use is my KIA Soul which is completely setup as a Bug-Out Vehicle. It is equipped with just about anything that you might need if you are forced to depart your home and live in the wild for a short period of time. Included in its many gadgets and accessories is a solar powered battery charger. This could certainly prove indispensable when off the grid.

Let’s move on to our plans or using solar as an emergency power source. Basic electronics will serve you well as you plan and lay out this solar system. In fact, such knowledge is essential if you are completing your own solar installation. In the event you are a little rusty on the fundamentals there are a host of videos which can be accessed on “YouTube” for free. That being said, the first thing we need to understand is the “Power Formula.” If you recall from your high school physics or electronic classes in order to find the power of an item measured in watts you must multiply the current in Amps by the Voltage. As an example, suppose you come across a solar panel that is reasonably priced. You make note that the panel is a 12 volt unit and puts out about 3 amps. Using the power formula you can calculate that this panel will provide you with 36 watts of power.

Most solar systems are based upon battery banks or small battery system. The solar cells powered by the sun charge the battery banks. The smaller the bank of batteries that you have the less power you have at your disposal – the larger the series of battery banks the larger supply of power you have. Suppose for example you are using two Trojan T-125 6 volt 240 amp hour batteries which are connected in series. The best use policy would dictate that you use only half of the available 240 amps in order to prolong the life of your batteries. That gives you 120 usable amp hours.

At this point you may be wondering exactly how many solar panels you will require to recharge those batteries. Since we have a 12 volt system being setup we would naturally employ a 12 volt solar panel setup as well. Delaware provides us with a minimum number of 4 hours per day of sunlight. Using a 12 volt, 150 Watt solar panel providing 8 amps per hour gives a total of 32 for the day you thus you would require 4 solar panels.

Harbor Fright has a 45 watt solar panel and they claim a maximum of 3 amps with at least an 80 percent guarantee. By multiplying the 3 amps by the 80 percent guarantee times the average sun day of 4 hours we derive a total of 9.6 amp hours here in Delaware. Therefore it would take approximately 12.5 hours to replace the 120 amp hours that we used. With that being said, we should start with deciding upon the battery pack while determining just how much power will be needed. Be sure to allow for those days when the weather conditions may not allow for efficient charging.

Your next question is likely to be concerned with what you can use for stored up power for. Suppose you have an accumulated 120 amp hours of power at your disposal. If you use one 12 volt television which consumes 3.3 amps and watch TV for 4 hours per day (4×3.3) you will use 13.2 amp hours. Additionally, if you have a 12 volt refrigerator which consumes 3 amps and you have it on for 24 hours per day which incidentally in most cases a refrigerator will not run for 24 hours per day but will cycle on and off as necessary. Using 24 hours at 3 amps as an example, will give us a ballpark figure (24×3) of 72 amp hours. Now let’s add some lighting to the scenario. Suppose you are using five led light bulbs rated at 1 amp each or a total of 5 amps and you run them for 6 hours per day (6×5) you will use up 30 amp hours. Let’s now add up these figures and determine how much of your 120 amp hours of use you have consumed. Adding all the amp hours used comes to 115.20 amp hours. As you can see when using solar you have to reduce your power consumption when you can. In conclusion, it would actually be somewhat beneficial to have a solar backup power system for when the SHTF.


Recharging Options for Electronics While Hiking

In this video, I look at my power options now that I’ve been upgrading my gear over the last few months.

I realized that unlike my previous generation of tech, I had chosen devices that used AA batteries, especially when it came to GPS & Satellite communicator. In the event that I ran low on power, I could swap batteries and extend the life of these. It also meant easy resupply of batteries by carrying just a few extra AA’s around in possibles bag.

However, most new devices have internal rechargeable batteries and I need to change my ways and get a few pieces that will be able to recharge these device.

My current electronic gear is composed of the following:
– Garmin fenix (GPS navigation, tracking)
– iPhone 5s (camera, mp3 player, communication)
– Delorme inReach SE (communication)

For the most part, I use my smartphone as a camera since cell reception is partial to non-existent in many of my hiking areas.

The new piece of gear I got which would allow me to recharge is an ETON FRX2 emergency crank radio. This unit has a little battery pack and USB outputs for charging. It has a small solar panel strip. I haven’t really used this much other than the radio.

But the next piece of gear I’ve just started to test out which is a GOAL ZERO Adventure kit; Nomad 7 solar panel and Guide 10 battery pack.

The battery pack can be charged using the solar panel or via USB. Which means easy charging at home before leaving or in the car as you drive out to the trailhead.

Guide 10 battery capacity appears as advertised as. I was able to top up all three device to 100% when they all were around 50%.

I just started testing charging a device directly from solar and the Garmin fenix was topped up to 100% (from 50%) in under 2 hours on a clear day.

Provided that you have clear skies these two charging options could extent your devices by a number of days.

Fitorch MR15:

Check out Fitorch!

Welcome To the Urban Survivor Channel. In this video we’re going to be taking a look at the MR15 flashlight from Fitorch. Fitorch makes a whole line of high quality and affordable EDC flashlights and in my opinion they are one of the best flashlight brands available. Before we begin, don’t forget to subscribe to the channel for more videos to stay up to date with all the latest gear, videos and giveaways.

The MR15 really stands out from the pack for a few reasons including its versatility in the types of batteries it can take, it’s USB rechargeable and it’s maximum brightness of 1200 lumens and its extremely long runtime.

So let’s dive in with the different battery Options. The MR15 comes with a 21700 battery which has 5000 mAH and also an Adapter which you can use with 3x AAA batteries. You can also use this light with a 20700 Rechargeable Lithium-ion Battery, an 18650 Lithium-ion Battery or 2 CR123As. If you are a flashlight addict, you probably have a few of these types of batteries laying around somewhere. This is very convenient for emergency situations in case you run out of one type of battery you can switch to something more common like AAAs or CR123As.

Another amazing feature is that fact that this light is USB rechargeable. There’s no need to deal with replacing batteries of extra chargers because everything you need is built right into the flashlight. Now that I’m used to USB recharging flashlights I won’t be using anything else. The MR15 comes with a USB cable for charging and there’s an indicator light on the side so you can easily tell when it’s charged up and ready to go! It has built in recharge, discharge and surge protection and electromagnetic protection so it should work in the event of an EMP. You can also lightly tap the power button and it will let you know how much juice is left in the batteries. It’s really nice not having to guess when it needs to be recharged.

The MR15 has 5 different brightness modes. The Specs I’m about to mention are based on the included 21700 battery. It also has two buttons. There’s an on/off button and also a seperate button to cycle through the different brightness modes. The Turbo mode has 1200 lumens and a runtime of 2.5 hours. It has a maximum throw of 256 meters. The High mode is 345 lumens and it can run for 7 hours. Medium Mode has 100 lumens nad it can run for 25 hours. Low Mode has 6 lumens and it can run for an impressive 229 hours which makes this flashlight one of the longest running available. Having the ability to keep the light on for so many hours would be excellent in a power outage or grid down scenario. There’s also a strobe mode with 1200 lumens which has a 5 hour runtime.

The Body is made from high strength aerospace grade aluminum and is mil spec anodized.It’s also impact resistant and waterproof up to 1 meter. The MR15 comes with a micro USB cable for charging, a battery, a wrist lanyard, a holster and a spare o ring.

If you are interested in this flashlight you can pick one up for $65 from Gearbest. There’s a link in the description below.
