LAST year, I installed a solar system under the net energy metering (NEM) scheme approved by the Sustainable Energy Development Authority (Seda). NEM is a mechanism which allows electricity consumers in Peninsular Malaysia and Sabah to sell excess electricity generated from their solar photovoltaic (PV) systems back to the grid.
I let the contractor do the entire justification and costing. Later, I found out that it was not really NEM because the energy buying rate from Tenaga Nasional Bhd (more than 50 sen/unit) was higher than the selling rate (31 sen/unit). Fortunately, the real NEM was implemented in January 2019 with identical buying and selling rates.
