Consistent savings - highly recommended

Have been using a hybrid solar system at my home from Wisolar since 2019 and seen an impressive reduction in my electricity utility bill from an average of R4500 to around R1200 monthly. I have installed 18 panels so Eskom is rarely used. I suspect the R1200 is the extra draw for my stove and geyser. The investment case works for me. When the money I paid for the system was in my savings account I received a mere R393.48 per month
