The most used instrument for solar energy harvesting is flat plate solar collector (FPSC). To improve the performance FPSC to get the optimal energy multi-walled carbon nanotubes (MWCNT) used on flat plate solar collector. This study describes the effect of synthesis of MWCNT-water based with concentrate ratio variations 0,1%, 0,3%, 0,5% and light intensity variations 415 W/m2, 515 W/m2 and 615 W/m2 with radiation from the sun simulator of 750 W/m2. Every light intensity was tested with different MWCNT-water nanofluids with concentrate variations 0,1%, 0,3%, 0,5%. The test was carried out 52 times for the collection of experimental data to provide valid test result. This study provides significant results on the use of nanofluids as a substitute for 0.5% multi-wall carbon nanotubes-water as a heat transfer fluid in improving the thermophysical properties that are superior to the base fluid. Increased light intensity and volume of nanoparticles also provide significant results on the performance of FPSC. In this paper, the greatest efficiency was found in the use of nanofluids and radiation intensity of 615 W/m2 with a volume of 0.5% nanoparticles with an efficiency of 90.45%. Increasing the fraction of nanoparticles into nanofluids provides the greatest efficiency-enhancing effect on the performance of FPSC. © 2024 American Institute of Physics Inc.. All rights reserved.
