Solar PV Systems
What is a Solar PV System?
A photovoltaic (PV) system is a system composed of one or more solar panels combined with an inverter and other electrical and mechanical hardware that use energy from the Sun to generate electricity. PV systems can vary greatly in size from small rooftop or portable systems to massive utility-scale generation plants.
How does it work?
Solar photovoltaic (PV) panels use cells containing a semi-conductor material to capture the sun's energy and convert solar radiation into electricity. ... When light shines on the semi-conductor the electric field across the junction between these two layers causes electricity to flow, generating direct current (DC).
Is there more than one type of PV System?
There are three main types of solar PV and storage systems: grid-tied, grid/hybrid and off-grid. They all have their advantages and disadvantages and it really comes down to the customer's current energy supply and what they want to get out of the system.
How much power doe solar panels really produce?
As of 2018, a typical solar panel produces around 320 watts of power, but panels come in many different wattage ratings, and finding one that produces exactly 320 watts is rare. The top 10 residential solar panels for 2018 includes panels rated to produce anywhere from 290 watts to 360 watts
Why should I invest in a Solar PV System?
