Solar energy has been a topic of interest for almost 150 years. Commercial solar water heaters began to appear in the 1890s, but it’s only in the last few decades that solar energy has become more widely used.
A solar panel consists of two layers, one that is negatively charged and the other just below it that is positively charged. The negative panel contains phosphorus and silicon which combined have room for four more electrons in their atoms, creating a negative charged plate with loose electrons. When photons of light from the sun hit the panel the photons they knock off the extra electrons which are drawn through conductive wires to the positive panel made of silicon and boron with atoms that have an extra space for the rogue electron. The electrons are forced to move a certain direction due to the electric field of the panels. This flow of electrons constitutes current which is directed to a device for use or into batteries for storage.
Chemistry The lead and lead-oxide plates alternate throughout the layers inside the battery. The plates sit in a bath of sulfuric acid. A current flows from the led oxide cathode (positive plate) to the lead anode (negative plate) meaning that the lead gives up electrons which the lead oxide accepts. The exchange effectively turns both plates into solid lead sulfate. One pair of plates makes up about 2 volts so to make 12 volt battery used in a motorcycle 6 pairs of plates sit next to each other inside the battery to make up the 12 volts.
Many solar panel systems will store the electricity generated in a chemical battery. These batteries are generally deep-cycle batteries which can generate a low current while sustaining of the life of a battery. Car batteries on the other hand are shallow-current which can discharge a large amount of energy but for a short time. The batteries used are either lead-acid batteries (sealed or vented) and nickel-cadium batteries. There are a variety of batteries you can use that differ primarily in the amount of energy they can store. However, more energy usually comes with a higher price tag.
Although true efficiency rating depends greatly on location, this panel has been rated with a 17 percent efficiency rating. One of the reasons it does so well is the technology has made it possible to maximize the output earned in weak lighting situations; making it possible to get more energy from less favorable conditions.
It also has a superb warranty, with a 12 year workmanship warranty and a 25 year output warranty. It also is able to withstand the harshest environments, preventing ammonia corrosion, salt mist corrosion, and also has a category ‘C’ fire test certification.
Batteries can be expensive and your controller ensures the battery will last. The last part of a normal Solar Panel rig is your inverter which will change the direct current generated from your solar rig to usable, alternating current. Some modules called AC modules have a converter already inside of them.
Between all of these different parts there is a good amount of wiring. Along with mounting hardware, grounding equipment, and other accessories you have a full solar system. After it is installed the system is very low maintenance and will provide electricity for twenty years or more. There are a variety of different solar panels that you can buy. They range from phonosolar 250 watt panels to 310 watt panels. The greater the wattage generally the higher the price and the higher the efficiency.
Lifespan The lifespan of lead-acid batteries varies greatly and is based on a number of factors. The first is the style of battery as discussed above; high power or high energy. The quality of the materials and manufacturing also plays part in the lifespan of a battery but ultimately the largest decider in a batteries lifespan is its use and maintenance. Heavily abused batteries in a car by people who don’t know better won’t last long while a larger, well maintained battery on a yacht can last twelve years.
