Solar Photovoltaic (PV) cells generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many PV cells within a single solar panel, and the current created by all of the cells together adds up to enough electricity to help power your school, home, and businesses.
Similar to the cells in a battery, cells in a solar panel are designed to generate electricity; except a battery’s cells make electricity from chemicals and a solar panel’s cells generate electricity by capturing sunlight instead.
How do these Systems Work?
The light from the Sun, made up of packets of energy called photons, falls onto a solar panel and creates an electric current through a process called the photovoltaic effect. Each panel produces a relatively small amount of energy but can be linked together with other panels to produce higher amounts of energy as a solar array. The electricity produced from a solar panel (or array) is in the form of direct current (DC). Although many electronic devices use DC electricity, including your phone or laptop, they are designed to operate using the electrical utility grid which provides (and requires) alternating current (AC). Therefore, for solar electricity to be useful it must first be converted from DC to AC using an inverter. This AC electricity from the inverter can then be used to power electronics locally, or be sent onto the electrical grid for use elsewhere.
4 Advantages of Photovoltaic Systems
Photovoltaic systems have many advantages over conventional power-generating technologies. The most important ones are listed below.
Solar PV systems can be designed for a variety of applications and operational requirements, and can therefore be adapted to your situation. There are domestic system sizes as well as commercial solar panel sizes.
Once your solar PV system is properly installed, it will only require minimal maintenance. In addition, their reliability and energy independence will offer you a lifetime of electricity generation.
Solar PV systems offer sustainable electricity generation, as they rely on a natural resource (sunlight), and their operations don’t create any noise or pollution.
Since photovoltaic systems are modular, it is easy to expand them or, even, in some cases, transport them.
Reliability and Grid Integration Research
Photovoltaic research is more than just making a high-efficiency, low-cost solar cell. Homeowners and businesses must be confident that the solar panels they install will not degrade in performance and will continue to reliably generate electricity for many years. Utilities and government regulators want to know how to add solar PV systems to the electric grid without destabilizing the careful balancing act between electricity supply and demand.
Materials scientists, economic analysts, electrical engineers, and many others at NREL are working to address these concerns and ensure solar photovoltaics are a clean and reliable source of energy.
Solar panels are a great way to generate renewable energy and save money on your electricity bill. There are many factors to consider when choosing solar panels, including the amount of sunlight you receive, and the type of solar panel you want.
