Students will be able to: discuss the principles of photovoltaics, explain PV system design, discuss PV system operation; describe system example applications; troubleshoot and analyze systems. Specifically students will be able to evaluate the design priorities for PV systems in different applications, discuss how the different types of solar energy technologies utilize solar radiation, differentiate between solar irradiance and solar irradiation; calculate differences between solar and standard time, evaluate how array orientation affects energy, use solar radiation data in sizing and estimating performance for PV systems; determine the suitability and condition of existing roofing, structural systems, and electrical systems and equipment; explain the function of an energy audit and identify opportunities for conservation and efficiency; describe various energy sources that can be interfaced with PV systems; translate the voltage, current and poser output of a PV devise from a reference condition to another operating condition; describe the construction and features of PV modules; identify the principal functions and features of charge controllers; describe the impacts of control algorithms and set points on system and battery performance; describe the functions and features of power conditioning units; calculate the critical design parameters, calculate the size and configuration of the battery bank and the array based on system requirements; differentiate between the various types of mounting configurations and their features; compare the various types of structural loads on arrays; identify the electrical codes, regulations, and practices applicable to PV systems; describe the functions and requirements of electrical balance-of-system components; differentiate between load-side and supply side interconnections; compare the technical and policy issues between net metering and dual metering; utilize an inspection checklist in checking systems for common installation code compliance issues; and determine the ways different incentives affect the life-cycle costs of PV systems.
