How Solar Panels On A Home Work

How do solar panels work to generate electricity.

How solar panels on a home work. Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass. Sunrun creates home solar panel systems that optimize for efficiency durability service and value. How does solar energy work. Once your designer has worked out what string length to be used i e.

The simple answer is that they utilize solar batteries to store energy. How many solar panels can be placed in series the designer needs to work out how many of those strings can be placed in parallel to get the desired system size. The range of technologies including small scale distributed solar mostly rooftop systems and large scale pv systems come with different advantages for home owners businesses and utilities. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect this flow travels in a circuit of wires that connect groups of solar panels called arrays.

As the sun hits the solar panels they generate direct current dc electricity where the electrons flow around a circuit in one direction. A standard solar panel also known as a solar module consists of a layer of silicon cells a metal frame a glass casing and various wiring to allow current to flow from the silicon cells silicon atomic 14 on the periodic table is a nonmetal with conductive properties that allow it to absorb and convert sunlight into electricity. Once installed on your roof solar panels convert sunlight into direct current dc electricity that flows into an inverter. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity.

Solar panels actually comprise many smaller units. However neither to solar panels nor the inverter have an inherent means of storage. Once solar panels are installed on your roof and begin to create energy there are a few steps required to turn it into energy your home can use. When solar panels are put to work in a parallel array their voltage stays the same but you add up their current.

Simply put the more energy your solar panels produce the more solar energy your home will use as opposed to power from your town grid. The home electrical panel is fed by the energy converted by the inverter. The different types of panels there are a few different. Many people question how solar panels work at night since they obviously no longer have light to generate power.
