Extends from IDEAS.Fluid.SolarCollectors.Data.BaseClasses.Generic.
Information
Record containing both thermal and electrical performance parameters for PVT
collectors. Thermal parameters follow the ISO 9806:2017 quasi‑dynamic
procedure and apply to both covered and uncovered designs. Note that the
ISO 9806 coefficient a5 is not included here because this
record extends from
IDEAS.Fluid.SolarCollectors.Data.BaseClasses.Generic , which defines heat‑capacity
handling at the collector level. As a result, a5 (thermal
capacitance) must be specified directly in the collector model as a
total heat capacity, typically by multiplying the specific capacitance by
the collector gross area (e.g., C = a5·Agross when using
CTyp = IDEAS.Fluid.SolarCollectors.Types.HeatCapacity.TotalCapacity). Electrical parameters follow manufacturer
datasheets.
