Many people in the solar industry are undergoing change;How silicon is made, what form it is when it is converted into a solar cell, how it is installed in a "kit" or modular system to limit complexity and time, and now how solar systems can be rented, instead of buying directly.With a new understanding of solar power systems, American homeowners now have cleaner, greener energy options.Electrons pop up from the "holes" of the silicon atom and flow through a series of solar photovoltaic cells to generate useful voltages.This concept and a little more is the focus of this article.The United States is in a huge, extensiveSolar energy is the main energy source of our family.Manufacturing costs are falling, awareness and demand are rising, and new options for leasing solar systems are exactly the same as new options for purchasing solar systems.How do solar photovoltaic cells generate current?The rest of this article explains some details related to the internal work of solar cells, and how they are arranged, when placed into a solar array mounted on your roof, the energy output of your solar system will be very different.Only when sunlight photons hit silicon, the internal electric field of the silicon diode generates a charge flow.When photons hit electrons in the silicon bond, they create holes-Electron pairs that freely separate and wander in a silicon lattice or crystal structure.Free electrons wandering around the p/n junction are pushed in one direction by the internal electric field.Due to the photoelectric effect, this movement of the electron causes the charge to flow stably in the circuit in the silicon structure, I .E.e.Current.Flow is proportional to the intensity of light and the energy conversion efficiency of the solar cells contained in the solar PV panel.The larger the sunlight shines on the silicon atom, the greater the number of electrons hitting free.In the end, this generates more electrons flowing in and out of silicon and into solar inverters.The entire continuous motion of the electrons illustrates why it is so important that all solar cells in the module or solar array get the same intensity of sunlight.It is important for solar panels to receive sunlight from the same direction and not to be obscured by trees or buildings.The exact number of photons from the Sun must hit each solar cell in order to hit the corresponding number of electrons in the next solar cell.In essence, the Sun's photons hit silicon, causing a chain reaction inside the silicon.The extra movement of free silicon electrons into and out of the holes produced in the silicon atom creates current and energy flow.Think about the game of billiards;The pool player hit the white ball into the imported bag, and the white ball hit the green ball into the imported bag.When you add more balls to hit each other, this happens in a chain reaction.What is a little bit distorted here is that the sun constantly hits the white ball (Ie.As long as the sun shines on the solar cell, the Sun photon will hit the silicon atom.A single solar cell in series produces only a small amount of voltage.They are usually connected in series, positive or negative in a solar cell array to produce useful voltages.When the photon of sunlight hits the solar cell, the internal electric field discharges the electrons from the battery in a continuous flow.In the photoelectric process, each electron that passes through the silicon structure obtains a gain of about half a Volt.The shifted electrons are collected in the wiring grid pattern printed on the battery.Module manufacturers connect enough solar cells in one module to generate useful voltages.The typical high voltage grid-connected module has 72 series units.The electrons moving around the solar cell get about half a volt voltage from each solar cell.After 72 solar cells in series, get enough voltage, about 40 volts.If more voltage is needed to generate useful current for home use, then solar modules can be connected in series.For example, the arrangement of typical residential solar systems and solar arrays has 8 solar modules in series.This leads to a final operating voltage of about 320 V.In the previous article, we connected solar cells, arrays and solar modules to give some explanation of the photoelectric effect, the photon of light impacts the electrons in the silicon lattice and provides energy for the flow.We also describe how in a module, the electrons flowing from one unit to the next can get about 1/2 volts gain from each unit.Renting a home solar system or buying it, the option to rent a home solar system is quickly becoming a viable option for home power needs.American homeowners can choose to produce renewable energy from the sun by renting a full solar system without having to buy one directly.This is an attractive option to allow homeowners themselvesProduce your own energy every month and keep saving.There is a suitable position (I.e.4 to 5 sun hours per day, enough roof space and average energy demand) and approved installation of solar system through on-site inspection, it is possible to use solar power generation at home on a rental basis.
