FAQ
Q: Is Prostar Solar Factory or Trade Company?
A: Prostar Solar is a factory located in Foshan city, nearby Guangzhou Baiyun International Airport.
Q: What is 300W Solar Panel?
A: Prostar 300W Solar Panel is the first step to converting your house to solar. Prostar high-performing polycrystalline solar panels achieve an excellent module-level efficiency of up to 15.62%. Whether you want to connect this to the electrical grid, or power your off-grid cabin, used widely across solar projects for homes, businesses, and large-scale power plants, these reliable, high-efficiency solar panels minimize installation costs and maximize kWh output. Prostar polycrystalline solar modules deliver above-average energy yields.
Q: What is Solar Energy?
A: Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.Solar energy technologies use the sun's energy and light to provide heat, light, hot water, electricity, and even cooling, for homes, businesses, and industry.
Q: How does 300W Solar Panel Work?
A: 300W Poly Solar Panel turns the sun’s light into electricity. One 300W Polycrystalline Solar Module is made by many small solar cells. Each of these cells uses light to make electrons move. The cell is made up of two different layers that are stuck together. The first layer is loaded with electrons, so the electrons are ready to jump from this layer to the second layer. That second layer has had some electrons taken away, so it is ready to take in more electrons.
When the light hits an electron in the first layer, the electron jumps to the second layer. That electron makes another electron move, which makes another electron move, and so on. It was the sunlight that started the flow of electrons, or electricity.
Q: What Are The Components Of a Photovoltaic (PV) System?
A: A PV system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.
Q: What Size of Solar System Do I Need?
A: It depends on how much electricity you use. Two homes the exact same size will use different amounts of electricity and therefore require different size systems. Major electrical loads within a home are air conditioners, electric heaters, pools, and other heating elements or motors.
That being said, an average 2,500 sq. ft. single-family home uses about 5,000 kilowatt-hours of electricity per year. A 3 kilowatt (AC) system will generate nearly all the electricity required for such a home on an annual basis. Sometimes a PV system can be installed that is slightly over-sized to allow for the possibility of a growing family or other factors that may play a part. When a system overproduces electricity, the unused portion is fed back into the grid and will actually be credited back to your utility account in a program called net-metering.
