How Solar Panels Work

All solar panels make use of photovoltaic cells. The inspiration for creating photovoltaic cells came about in 1839 when Edmond Bacquerel, a French scientist, noticed that certain materials created sparks when exposed to sunlight. By the late 1800s, researchers realized they could harness this release of electricity, which they termed the photoelectric effect, and created the first photovoltaic cells out of selenium.

Photovoltaic cells are comprised of two layers of semiconducter material, most commonly crystallized silicon. Silicon by itself is not a good conductor of electricity, but with the addition of certain impurities, a process known as doping, it becomes highly conductive. The lower layer of a photovoltaic cell is usually doped with boron, while the upper layer is usually doped with phosphorous. Boron facilitates a positive charge in silicone, while phosphorous facilitates a negative charge. Negatively charged silicon has a lot of extra electrons that are not bonded with neighboring atoms. Positively charged silicon has the opposite property. It has a lot of extra atoms that have no electrons to bond with.

When light strikes a photovoltaic cell, it is absorbed by the semiconductors causing them to release electrons. If the P-type and N-type semiconductors are placed next to each other, all of the free electrons released from the the negatively charged layer rush to bond with the free atoms in the positively charged layer. Not all of the electrons will find atoms to bond with, however. This mad rush of electrons also produces an electric field at the P-N junction (the area where the two semiconductors meet).

This electric field allows electrons to flow from the P-type semiconductor to the N-type, but not in the other direction. Once an equilibrium is reached in the N-type semiconductor, the extra electrons have nowhere left to go since they are blocked by the electric field from going back to the P-type semiconductor. By attaching an external circuit, a new pathway is created for electrons to flow from the negative layer to the positive layer. This flow of electrons passing through the circuit produces an electric charge that can be used to power other devices.

Benefits Of A Portable Solar Generator

Being left in the dark with no power is not a situation that anybody hopes to find themselves in when camping or dealing with an emergency. Unfortunately, for many owners of traditional generators, this is a situation that can happen all too often. You may forget to bring along an extra tank of gas or keep some stored in the shed. Even if you do happen to have remembered to keep a tank of gas lying about, most people don't realize that it only takes three to six months for gas to go bad, so not only do you have to remember to keep gas on hand, you also have to remember to change it out every couple of months.

Unlike with traditional generators, with a solar generator there is no need to worry about keeping gas lying around. Solar generators are self-sustaining and can always produce new power, as long as the sun is shining. They also contain a battery to store the excess energy generated during the day, which can then be used to power your devices throughout the night.

Solar generators are ideal for camping situations as they are completely silent. Since they make use of semiconductors and electric fields to produce electricity, they don't have any moving parts. This makes them more durable and reliable than their mechanical counterparts.Traditional generators make use of a motor to rotate the components of an alternator, thereby creating an electric field. The motors used to power traditional generators are often quite loud. Some of the quietest models still produce at least 53dB of noise, which is roughly equal to the sound of light traffic passing by you on a street, with most models producing closer to 75dB, which is roughly equal to the noise of a vacuum cleaner. Not only is a traditional generator loud and and annoying if set up near your campsite, you won't be doing your neighbors any favors either.

Finally, probably one of the biggest benefits of solar generators is that they are eco-friendly. Unlike traditional models, they neither consume fossil fuel nor release noxious gasses, like carbon monoxide, into the air. This means you can use one anywhere that is exposed to sunlight, such as in a greenhouse, without having to worry about poisoning yourself or the environment.

Three Things To Consider When Choosing A Portable Solar Generator

Before clicking that buy button on that solar generator you've had your eye on, you should stop and ask yourself a few questions to ensure it meets your needs. While a host of other features may play into your decision, the three most important determining factors should be input, output, and storage.

First, ask yourself what kind of input works best for you. Some solar generators have their panels mounted directly onto the unit or built-in to it, while others are connected to the panel by a cable. Panels that are connected by a cable will offer you more placement options, as both the panel and the generator don't need to be set in the same spot. The longer the cable, the more versatile. There are also models available with panels that fold up for easier transport, like those commonly used in small solar chargers.

Next, ask yourself how much power you need. What are the wattage and voltage requirements of the devices you plan on charging with it? Some models may produce as little as 50 watts, while others are capable of outputting well over 1,000 watts. If you just plan on using your solar generator to power your laptop and speakers while camping, a small model will often suffice. On the other hand, if you want it to function as a power backup for your home refrigerator, you will obviously need a much stronger unit.

The final concern regards power storage, or battery size. The larger the battery, the more energy a model can store for overnight use. As with the rest of the features, though, you'll have to find the model that best balances your portability and power needs.
