Assess combined AMS-I.J applicability conditions

Evaluates core AMS-I.J applicability criteria for solar water heating projects and returns a tidy summary of the results.

assess_ams_ij_applicability(
  capacity_mwth,
  annual_irradiation_kwhm2,
  backup_fraction,
  capacity_threshold_mwth = 45,
  irradiation_minimum_kwhm2 = 1200,
  backup_maximum_fraction = 0.2
)

Arguments

capacity_mwth

Rated solar thermal capacity in MWth.

annual_irradiation_kwhm2

Annual solar irradiation in kWh/m\(^2\).

backup_fraction

Fraction of useful thermal output provided by auxiliary systems.

capacity_threshold_mwth

Capacity threshold in MWth.

irradiation_minimum_kwhm2

Minimum annual irradiation in kWh/m\(^2\).

backup_maximum_fraction

Maximum allowable auxiliary fraction.

Value

A tibble summarising each applicability condition and whether it passes.

Examples

  capacity_mwth = 20,
  annual_irradiation_kwhm2 = 1900,
