How Does It Work?

1.    Solar power is not as expensive as you think. Sunlight is free. All you need is a solar panel and power pack to         store that free sunlight power. To get started with solar power we have kits starting at about $130.00

2.    No need for an advanced degree to use. Plug and play system means instant power for anyone. No red and         black wires to worry about. No extra cables to figure out and purchase. At GOAL ZERO you basically open up your         solar panel and let the sun do all the work.

3.    Not just for calculators and roof tops. The Guide 10 is small and compact enough to fit in your pocket or back         pack. Use our power packs and solar panels to power your phone, laptop and more.


4.    You can charge just as fast from the sun as you can from the wall. You can plug in your cell phone to a power         pack that has been charged from the sun and it charges at the same rate as plugging it into the wall. It will just         charge up in the most eco-efficent way possible.

5.    Solar power is not magic. Turning sunlight into electricity is really just another form of energy conversion. It’s         kind of like burning wood or coal. Burning wood or coal simply converts chemical energy into heat energy. It’s the         same thing with a solar panel. The photovoltaic effect converts the light power into electrical power.

6.    Solar panels are not huge. Thanks to recent advances in solar technology what once fit only on your roof can         now fit in your pocket.

7.    Solar Panels are not fragile. We have run extensive tests on our panels. From dunking them in rivers for hours,         to running them over with trucks. We even have thrown the glass-covered panels multiple times on the concrete.         They are made for what you can dish out.

8.    Solar Power can be used to enhance your everyday life. You will find that you will use portable solar power         everyday. You will feel smarter for doing it. We challenge you to never have the need to buy AA or AAA batteries         again.


09.  AC/DC is not just a rock band. AC is Alternating Current and DC is Direct Current. Here’s what you need         know: the voltage of an AC source can be changed by using a transformer, while DC can’t. On the other hand         DC can charge a battery while AC can’t. Electrical power is delivered in two ways: Alternating Current (AC)  and        Direct Current (DC). Direct Current is electricity that moves in one direction. Alternating Current moves back         and forth.


10.    Power Packs measure the amount of energy stored in Watt Hours. Wattage is the result of Volts x Amps. For         instance 5 volts x 2 amps = 10 Watt. Watt-Hours (Wh) is an amount of power (in watts) expended in one hour.         For instance, 120 Watt Hour power pack will run a 3 Watt light bulb for 40 hours. (120/3=40)


11.    Mono-crystalline solar panels are the best you can buy. There are all kinds of materials used for photovoltaics         including mono-crystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium         gallium selenide/sulfide. At GOAL ZERO, we use mono-crystalline solar panels because they are the most efficient         and very reliable. They have a lifespan of 10 to 30 years and provide the highest wattage per square foot. Plus,         they perform best in most conditions including low light.

12.  Solar Power is just plain super awesome. Let’s face it, using and having the power to be reliant on the         greatest resource the earth provides is just super awesome. Become EmPowered!

POWER 101

In this section we are going to break down what "power" is and how it works. We are not talking about "political power" or "power of attorney". No, we are talking about electrical power.

What is electricity?

Let's start at WHAT electricity is. Electricity is a form of energy. To get a little more scientific it is the flow of electrons or energy from one thing to another. You see this flow of electrons happen every day; when you turn the lights on (if the electricity is working) there is power flowing from your local power plant to your light bulb and when you plug anything into the wall outlet it is receiving power from an exchange of electrons or energy.

AC/DC not just a great band!

Electricity gets even more interesting from here. There are two different "types" of electricity: Alternating Current (AC) and Direct Current (DC). They mean exactly what they sound like. DC is a direct flow of power in one direction while AC is power that changes or alternates direction.

A few facts about DC power:

1. Most vehicles use DC power....to run the lights, the radio and even to start
2. It is the only "type" of power that can be stored in something like a battery.

A few facts about AC power:

1. Most "Wall Plugs" are AC power systems. That kind of power comes from a power plant.
   The most common power plants are Hydro (water), Coal, or Nuclear.
   
   
2. AC power is much better at traveling over long distances.

Watts going on?

It's time to get down to the nitty-gritty; Watts, Volts and Amps. You really don't need to be worried, let's take it one step at a time.

Amps

Electricity consists of the flow of electrons through a conductor such as an electric wire. You can't see electrons but a helpful analogy is to think of electricity as the flow of water through a pipe. We measure the rate of flow of electricity as an electric current (notice the water analogy again if we think of a river current). Electric current is measured in Amperes, shortened to Amps or simply the letter A. A current of 2 Amps can be written as 2A. The bigger the current the more electricity is flowing.

Volts

So what makes the current flow in the first place? A device such as a battery provides a potential difference in an electric circuit. If we go back to our water analogy, the battery is like a water pump that propels water through a pipe. It creates pressure in the pipe causing the water to flow. So how do we measure this pressure? We call electrical pressure Voltage and measure it in Volts, shortened to V. A voltage of 3 volts can be written as 3V. The bigger the voltage the higher the pressure and the more current flows. But in order for the current to flow, the electrical conductor or wire must loop back to the battery. If we break the circuit, with a switch for example, then no current flows.

Watts

So how do Current and Voltage relate to one another? Well, the bigger the current the brighter the light and similarly the bigger the voltage the brighter the light. Both the voltage and the current in the bulb determine how much energy is released in a certain time. The Watt is a measure of power or how much energy is released per second. It can be shortened to W. One Watt can be written 1W. We can calculate the power released in a bulb by multiplying the voltage in Volts across the bulb by the current in Amps flowing through the bulb (W = V x I). For example a current of 2 Amps flowing through a bulb with 12 Volts across it generates 24 watts of power. In the UK, domestic power is supplied at 240 Volts. A 100 Watt bulb will therefore draw a current of 100/240 Amps (about 0.4A). This means a 1A fuse can be safely added to the mains plug of a desk lamp with a 100W bulb because 1A is much greater than 0.4A. In the USA, the domestic supply is typically 110V, safer than the UK, and this means a 100W bulb draws a current of 100/110 Amps (about 0.9A).

SOLAR 101

What is solar?

Solar power is energy that is collected from the sun. The amount of sunlight that reaches the earth is enough energy to power the needs of the entire world more than 8500 times over. How does it work? Solar power cells consist of two layers of treated silicon. The bottom layer is positively charged and the top layer is negatively charged. When the sun hits the panel electrons move and create electricity. What does solar efficiency mean? Manufacturers test their solar panels and cells in perfect conditions (74 degree, 1 MPH wind), which is never what actually happens in reality. However, with the correct orientation to the sun and good sunlight, you can expect on average around 60% of the rated wattage that the panel advertised.

What are the different types of solar and why do we use mono-crystalline?

Mono-Crystalline: This is the technology GOAL ZERO employs 11-22% efficient - most efficient and very reliable Lifespan 10 - 30 years highest wattage per square foot Made from single silicon crystals Perform best in the most conditions (light & temperature) Performs well in low light conditions.    Poly-Crystalline: 8-15% efficient Made from multi-crystal silicon Looks like fish scales or shattered glass Simpler manufacturing process    Amorphous: 5-6% efficient Old technology Weak: break easily Nice looking Rigid Work well in shady conditions Typical use: solar calculator    CIGS 5-10% efficient Flexible More expensive Bigger size Easy to manufacture
