KUALA LUMPUR: Tenaga Nasional Bhd 's reneweable unit plans to offer financing self-generation packages for solar photovoltaic (PV) panels for residential customers by year end as the demand for green energy climbs.These packages will be offered by TNB Renewables Sdn Bhd's unit GSPARX Sdn Bhd which has started offering packages to commercial and industrials customers.GSPARX was set up to meet the huge demand for financing self-generation for solar PV investment.It is among the first investment companies in Malaysia to offer zero upfront capital expenditure (capex) solution for the installation of solar PV panels.What is significant is that its customers do not have to make any upfront payment as GSPARX will bear the cost for purchasing and installing solar PVs.GSPARX's customers will benefit from saving and hedging opportunities.
