Solar photovoltaic panels are smaller than the design value

Why is it important to understand the photovoltaic (PV) effect?

After discovering the photovoltaic (PV) effect, understanding physical principles, developing practical technology, decreasing the price of solar cells and modules production, creating massive amounts of PV systems and huge PV plants - maintenance and analyzing failures of PV systems and plants are becoming more and more important issues.

Why are solar panels less efficient than individual cells?

Solar panels are slightly less efficient at energy conversion per surface area than individual cells, because of inevitable inactive areas in the assembly and cell-to-cell variations in performance. The back of each solar panel is equipped with standardized sockets so that its output can be combined with other solar panels to form a solar array.

What is the importance of sizing a solar PV system?

Appropriate system design and component sizing is fundamental requirement for reliable operation, better performance, safety and longevity of solar PV system. The sizing principles for grid connected and stand-alone PV systems are based on different design and functional requirements. Provide supplemental power to facility loads.

Why is thin film PV a good choice for home solar systems?

As the PV materials used in these types of photovoltaic cells are sprayed directly onto a glass or metal substrate, the manufacturing process is therefore faster are cheaper making thin film PV technology more viable for use in a home solar system as their payback time is shorter.
