“…In general, interest in using parabolic dish concentrators arises due to the potentially high concentration ratios and high optical efficiencies which allow to reach high receiver temperatures effectively [3] [4]. Solar dish concentrator installations of various sizes and shapes have demonstrated peak flux levels ranging from 1-12 MW/m² [5] [6] [7] [8] [9]. Previous efforts on the power conversion unit for dish systems have mainly focused on the integration of Stirling engines [10] [11] as compared to this work where a MGT is integrated.…”

“…Segundo Schmitz et al (2017), a calibração foi feita pela análise das temperaturas de entrada e saída dos dois circuitos de refrigeração, e foi comparada pelos dados de DNI registrados. Mas, no método de calibração pelas medições de temperatura, foi considerado as perdas por convecção da placa de cobre.…”

“…A calibração desse sistema é feita por aquecimento elétrico de um fluido de refrigeração do calorímetro. Schmitz et al (2017) verificaram uma relação linear entre a energia elétrica e a energia térmica do fluido. No teste sob o Sol, 𝑄 𝑒𝑙 = 𝑄 𝑆𝑜𝑙 𝜌 𝑐𝑜𝑛𝑐𝑒𝑛𝑡𝑟𝑎𝑑𝑜𝑟 (1 − 𝜌 𝐴𝑙 2 𝑂 3 ).…”
