Note: Standard trough aperture is 5-6m. Rim angle of 70-90° balances concentration and structural cost. HTF temperature typically 290-400°C.
Reference
Focal Length = W / (4 x tan(φ/2))
Collector Area = Aperture x Length
Heat Output = Area x DNI x Optical Eff [kW]
Concentration Ratio = W / (π x D_receiver)
Optical Eff ~ 0.75 (mirror reflectivity x intercept x transmittance)
