When designing a PV system, location is the starting point. The amount of solar access received by the photovoltaic modules is crucial to the financial feasibility of any PV system. Latitude is a primary factor. 2.1.2. Solar Irradiance
DESIGN & SIZING PRINCIPLES 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.
Stand-alone PV systems can be considered a type of banking system. The battery is the bank account. The PV array produces energy (income) and charges the battery (deposits), and the electrical loads consume energy (withdrawals). The sizing objective for stand-alone PV system is a critical balance between energy supply and demand.
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.
All decisions regarding the engineering of a large solar PV power system must be carefully considered so that initial decisions made with cost savings in mind do not result in more maintenance costs and decreased performance later in the system’s lifespan.
In evaluating solar viability for a PV farm, a comprehensive analysis is conducted to assess topographical features, shading patterns, and soil conditions. The goal is to ensure that the chosen site offers optimal exposure to sunlight throughout the day, minimizing shading and maximizing energy production.
