off grid solar system
The development of solar power goes as far back as a century ago. Going back in time, solar energy was employed basically to make steam to be used in operating machinery. With the discovery by Henri Becquerel of the "photovoltaic effect" the conversion of sunlight, solar electric energy was ushered in. After Becquerel's conclusions, Charles Fritts established the earliest version of the solar cell with a delicate film of gold encasing sheets of selenium.
Our basic solar panels were spawned from a fairly basic beginning and have made great advancements. Solar panels are charged by the sun, that power is then transformed into power that can be tapped into for electrical usage. One solitary solar panel is not designed to take an extraordinary workload. With this in mind, more than one panel will be necessary. By considering the suggestions below, you will have a better idea of what to look for when purchasing solar panels.
Inexpensive Solar Panels: The majority of us think that there is such a thing as cheap or inexpensive solar panels. The only way that this will happen is when the panel is brand new and from a known company. Finding cheap solar panels is possible, but probably only if you are satisfied with defective or used products. If you are thinking about buying solar panels that are faulty, they will still be able to give electricity. Going the cheaper way isn't always best, since panel efficiency is up to 60% less than with a new panel. For household use, though, this is still tolerable considering that it is possible to obtain these cheap solar panels for free or at a bargain price.
Types of Solar Cells: When thinking of solar panels for your solar power system, it pays to know the three main types of solar cells in order to know which type is ideal for your needs. To start with there is the monocrystalline silicon, which is the most valuable because it produces the most efficient cells due to their small size; which will make a more compact panel. The monocrystalline panels are plainly will have a steep price.
After that, the next choice is polycrystalline, also called multi-crystalline silicon. It is the most favored choice given its superior combination of performance and savings. With recent enhancements, polycrystalline modules are now being brought closer to monocrystalline in terms of size, efficacy and heat resistance. It is currently acknowledged by European businesses as the norm. The amorphous is called thin-film silicon and is the third principle sort of solar cell. This one generates a solar cell with a less than efficient use because it uses so little silicon to start with. Consequentially, amorphous will use larger space than the other two solar cells. This is a pertinent detail to take into account when considering potential advances down the road. When installing a solar power in your home, the best system would use the polycrystalline solar panels.
The Amount of Wattage: The price that you pay for a solar panel is in direct proportion to the amount of watts than it can produce. The latter is directly related to the performance of each panel so much so that a 100 watt panel under normal circumstances will give off 100 watts of electricity per hour and a 200 watt panel will generate 200 watts in an hour. It is actually simple math; a 100 watt solar panel will cost you half the price of a 200 watt solar panel.
With solar panels, not only are you able to save money on bills over the long term, you can also help in the preservation of the environment. As long as you maintain your solar panel electrical system well, you will generate electricity for many decades.
