Optimizers in Solar PV System
What are the benefits of power optimizers and why are they needed? When installing solar panels , the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels , there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components, and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy than other panels and in some cases up to 50 percent less. With the help of optimizers, each panel can be placed in a separate group, and the aim is to ensure that the productivity of each solar panel is as high as possible. It is important to note that optimizers can also play a role in ensuring electrical safety. SolarEdge was one of the first to come on the market with optimizers, and their SafeDC function ensures that the high DC voltage of th...
