Different manufacturers have different prices for solar panels, but comparing the value of solar cell is quite simple.
Light is converted into electricity by solar panels, which are like big square plates. The source of light is the Sun which is available most of the time. There are similar sizes of small cells in a solar system. These cells spreading over a large area work as a unit so that most of the power could be utilized. Working mechanism of solar panels is quite simple; the more area receives the light, the more electricity is produced by the panel.
Cheaper prices for solar panels
Different manufacturers have different prices for solar panels, but comparing the value of solar cell is quite simple. The price is calculated according to $4.30 per watt. For example, if you want to buy a 25 watt solar panel, your total cost would be around $107. This calculation should be kept in mind while purchasing any solar panels and cells.
Experts suggest that sometimes latest panels may or may not be reasonably priced. As far as the size is concerned, it does not matter if you have sufficient mounting space for the panels. If primordial technology for an inexpensive dollar per watt price is affordable and you can use it properly then go with it. You can save a lot of money.
New solar cells are quite expensive. But, scrap solar cells can also be used as they can save substantial amount while giving you the same benefits. Scrap cells does not mean that they are second hand used, but the cells receiving fault while being manufactured in the company. These cells are easily soldered and will cost you below $2 per watt. Buying scrap solar cells is not a big deal. Manufacturing units advertise their sales online.
These cells are good for you if you have big space for large solar panels arrangement made up of scrap solar cells, if you want to save money and have a bit of technical or practical experience like soldering or repairing.
Types of Solar Panel Mounts
Solar panels are offered in different sizes, which are preferred as per the space available for installation. Generally, these panels have been divided in three categories which include pole mounts, ground/roof or universal mounts and flush mounts. Each of them has its own advantages and disadvantages. Before going for any version you should carefully assess each category.
Solar panels for home
If you love your environment and want to save it for the next generation, you will find a lot of benefits associated with solar panels. Electricity is produced through the Sun light without creating any toxic material or affecting other natural resources. Solar panels can be installed at your home and business establishments. In addition to saving environment, they also boost the value of property anywhere in the world.
Due to conventional energy sources, which is easily available most of the time, solar power plants are being preferred being price competitive. In most of the American states such Colorado, Arizona, New Jersey and California etc, people are compensated for the initial investment cost. There are other incentives and rebates are available for the power produced.
Governments are also encouraging people to install solar power plants on homes by providing financial support options.
Energy saving for home
Solar panels projects are getting popularity for household utilities as they have proved to be energy saving. They have brought down energy bills to great extent while providing clean electricity. Thus energy saved this way can be used for other works.
Due to the popularity of solar panels all over the world on ground levels, companies in North Charleston have been planning to hire exploit the sun systematically. In North Charleston, the roof of Boeing Co.'s huge 787 Dreamliner will have a sample of the photovoltaic solar panels.
Easy to start with one panel
The mechanism of solar panel is quite simple. The sun continuously releases the radiation, which are collected by the solar panels and then it converts them into the electricity. There are numerous small individual solar cells in solar panel. These small cells work as a unity in similar way just like the semiconductors. This way an outsized area PN junction diode is utilized.
When the sun rises spreading its light all over, solar cells are exposed to the light and this sunlight starts to be converted into energy with the help of PN junction diodes. When photons hit on the surface of solar panels, electrons are knocked out making them come out of their orbit. In this reaction, energy is generated from the hitting photons. Solar cells also convert them into electric fields by attracting these jumping electrons in a directional current. When this happens electricity is generated in the solar cells by the metal contracts.
In brief, if the quality of solar cells is high and there are more solar cells in any solar panel then more electrical production would take place. The whole process is termed as the Photovoltaic Effect, which means sunlight can be converted to useful electrical energy.
Does solar panel work at night?
As the sunlight is the main source of energy which is available only when the sun appears, due to which energy cannot be generated at night. This is also good for the solar system because it gets sometimes to rest until the next day. It automatically starts generating energy once the light falls on panels.
Is it possible to save the energy produced by the solar panels?
Definitely! Saving solar energy us just like the way we store traditional electricity in batteries. This is the advantageous point of solar system that we have electricity 24 hours even when our traditional generators stop working. So, if you think that what will happen at night? Energy saved in batteries will continue illuminating your home with solar light. You can also operate your computer, washing machines or other electronic gadgets the way you usually do. But, also remember, solar panel system is environment friendly, but the electricity produced is unsafe.
