This paper presents techno-economic analysis of a parabolic trough collector (PTC) for various integration points in a boiler network. The complete system is simulated with solar collectors utilized in 3 different integration schemes: a) feed water heating, b) direct steam generation, and c) process integration. The effect of integration point on the solar fraction, levelized cost of heating (LCoH), and carbon mitigation potential is presented for a real case dairy unit in Dubai. The simulations are performed using TRNSYS and MATLAB. Results show that the least global LCoH for highest solar fraction is achieved for process level integration. A relatively higher carbon mitigation can be achieved in steam integration, at expense of higher LCoH. The excess energy from the solarfield can be stored in thermal storage tanks and can be utilized when there is intermittency in solar radiation
