Off Grid Solar Power - How To Calculate Your Needs

Thinking of setting up an off-grid solar power rig? One of the main challenges you’ll face is accurately estimating/calculating your power needs. This serves as the foundation of your entire system; it partly determines the number of solar panels, the inverter size, and battery sizing.

The underlying goal of any off-grid solar power rig is to produce enough power to meet the consumption needs of a household. As Mat & Danielle from Exploring Alternatives explain in this YouTube video, calculating your off grid solar power requirements is the first step is determining what you’ll need your solar power for.

Find all the electronics and appliances in your home of camping van and check the output wattage of each device. If the output is in volts and amps, all you have to do is multiply the figures to get the output wattage – i.e., Volts x Amps = Watts. (PS: 1 Amp = 1000 Milliamps).

After figuring out the total output wattage of your appliances, round the figure up to create a safety net. For example, Mat calculates that his appliances need 115.7 watts — but he rounds it off to 120 watts. This accounts for any inefficiencies from decreased performance and unforeseen power needs.

Next step is figuring out how long you typically use these items (Tip: Think on the higher side for cushioning). From there, you can enter the figures into an online Solar Sizing Calculator. You’ll then get the recommended system size and battery size for your daily needs. You can now use the results to design an efficient off-grid solar system.

Perhaps one of the greatest challenges is calculating how much power you will actually get from your solar panels. This can vary widely due to weather conditions, time of year and placement of the panels. A 400W panel only generates 400 watts in full sun when facing the sun directly. Looking up the average number of hours of sunshine per year in your location is a good starting point. In cloudy conditions your panels will produce a little extra energy – perhaps 10% of their rated power, but this will be more than offset by the panels’ angle to the sun unless you have a tracking system that follows the sun from sunrise to dusk.

As a final note, take special care when selecting an inverter. It should be big enough to meet your wattage consumption at a time—and small enough to minimize its power consumption (inverters are fairly efficient but do consume some power and the bigger, the more solar power it drains).

This Crazy Off Grid Device Literally Makes Drinkable Water From Fresh Air:

According to NASA, the U.S. is expecting a 100-YEAR LONG MEGADROUGHT.

It's already begun. Ask the farmers in California. They know.

Every survivalist knows that water is of critical importance. You NEED an independent water source that you can count on!

As an interesting "survival rehearsal" - imagine that you turned the tap on right now and nothing came out. How long would you last?

But what if there was another water source literally hidden in plain sight. That's right, I'm talking about the atmosphere!

The amazing thing about getting water from the natural moisture in the air... is that it is ALWAYS available.

This gives you real water security!

� What Tinnitus Does To Your Brain Cells (And How To Stop It)

After 47 years of studies and countless brain scans done on more than 2,400 tinnitus patients, scientists at the MIT Institute found that in a shocking 96% of cases, tinnitus was actually shrinking their brain cells.

As it turns out, tinnitus and brain health are strongly linked.

Even more interesting: The reason why top army officials are not deaf after decades of hearing machine guns, bombs going off and helicopter noises...

Is because they are using something called "the wire method", a simple protocol inspired by a classified surgery on deaf people from the 1950s...

Most People Don't Have The Guts To Try This:

An amazing discovery in an abandoned house in Austin, Texas: A lost book of amazing survival knowledge, believed to have been long vanished to history, has been found in a dusty drawer in the house which belonged to a guy named Claude Davis.

Remember... back in those days, there was no electricity... no refrigerators... no law enforcement... and certainly no grocery store or supermarkets... Some of these exceptional skills are hundreds of years of old and they were learned the hard way by the early pioneers.

We've lost to history so much survival knowledge that we've become clueless compared to what our great grandfathers did or built on a daily basis to sustain their families.

Neighbors said that for the last couple of years Claude has tried to unearth and learn the forgotten ways of our great-grandparents and claimed to have found a secret of gargantuan proportions. A secret that he is about to reveal together with 3 old teachings that will change everything you think you know about preparedness:

What REALLY Happens When You Bury a Shipping Container? (Hint: It's A Bit Crazy...)

Shipping containers are all the rage - but if you are thinking about buying one, you MUST watch this video first:

Do not, I repeat do NOT do what these lunatics did! Can you spot the "fatal mistake" they made?

There's a general belief that if you bury a shipping container you can create an awesome root cellar / storm shelter / survival bunker.

But is a shipping container strong enough to handle the pressure?

I Can't Help Showing This Off:

If you haven't heard of Claude Davis yet do yourself a huge favor and watch this video.

One of the smartest guys I ever had the pleasure of meeting, Claude set-up a unique prepping system that changed his life forever.

I already tried it myself and let me tell... you I was completely blown away... His surprising tactics could make your life easier and give you the peace of mind you deserve.
