MPPT is a method to extract maximum power from a PV module. MPPT itself is divided into a few parts of the algorithm, InC is one of them. InC operates by comparing InC and IC. The advantage of this algorithm is that it has high accuracy for MPP estimation but with slow response to MPP. Changing the SS value to a high value can reduce response time to MPP but reduce MPP accuracy. To avoid this VSS is needed. The implementation of FPGA needs to compromise with the FPGA's resources. The division operation needs more resources and more time than others. The InC modification changes the InC and IC comparison with the comparison of dVI and dIV values to reduce division operation and use the difference value of dVI and dIV to calculate VSS. The result based on the first scenario accuracy of the proposed algorithm increased by 7,8% to FSS with a big value, 7,2% to FSS with a small value. Response time to MPP increases by 2% faster than FSS with a big value, 31% faster than FSS with a small value. The second scenario accuracy of the proposed algorithm increased by 1,7% to FSS with a big value, 2,9% to FSS with a small value. Response time to MPP increases by 8,82% faster than FSS with a big value, 36,73% faster than FSS with a small value
