Q: What is a photovoltaic (PV) system design?
A: Photovoltaic (PV) system design refers to the process of determining the components and specifications needed for a solar
energy system that meets specific energy needs and requirements.
Q: What are the factors to consider when designing a PV system?
A: The factors to consider when designing a PV system include location, shading, orientation, slope, electricity consumption, budget,
and local regulations.
Q: How do I determine the size of a PV system?
A: The size of a PV system can be determined by considering the energy consumption, the amount of available space for panels, and
the budget for the system.
Q: What is the difference between a grid-tied and an off-grid PV system?
A: A grid-tied PV system is connected to the main electricity grid and sends excess energy generated back to the grid. An off-grid PV
system is a standalone system that is not connected to the main electricity grid and stores energy in batteries for later use.
Q: What is the impact of shading on a PV system?
A: Shading can significantly impact the performance of a PV system by reducing the amount of sunlight reaching the panels. Proper
design and positioning of panels can help minimize the impact of shading.
