- •
A new optical-thermal model for a linear Fresnel solar reflector is presented.
- •
Solar radiation transfer and energy conversion processes are simulated integrally.
- •
Yearly optical efficiency of 60.1%–44.7% from the equator to N50° is revealed.
- •
Heat transfer characteristics and thermal performance of the receiver are analyzed.
- •
Radiation loss from tubes is found to be dominant and contributes around 81%–87%.
