Solar streetlights not suitable everywhere, says minister

Solar-powered streetlights are not a one-size-fits-all solution, according to Malaysia's Minister of Works, Datuk Seri Alexander Nanta Linggi. He stated that the suitability of Integrated Solar LED (ISLED) lights depends on the location, technical requirements, and lifecycle costs.

At this time, the use of solar streetlights is more suitable for locations far from the electricity grid, areas that are frequently subject to cable theft or vandalism, as well as village roads and rural areas.

Linggi explained that ISLEDs are most appropriate for areas distant from the main electricity grid, places frequently targeted by cable thieves or vandals, and for roads in villages and remote regions. This approach can reduce the need for new electricity infrastructure and simplify maintenance.

However, replacing conventional LED streetlights in areas with reliable electricity supply is still more cost-effective. The initial installation cost for ISLEDs is higher, and their batteries, a component requiring frequent replacement, account for about 60% of the total lamp cost. The Ministry of Works will continue to evaluate the targeted use of solar streetlights based on technical feasibility, cost-effectiveness, maintenance, and green technology benefits to ensure the best value for the government and the public.

The battery component is one of the components that most frequently requires replacement and its cost is estimated at around 60 percent of the total cost of the lamp.
