Promoting Solar Lighting in the Philippine
On February 23, local time, the Philippine Department of Public Works (DPWH) released the overall design guidelines for solar lighting along national highways.
In Departmental Order (DO) No. 19 of 2023, Minister Manuel Bonoan approved using solar street lighting in public works projects, followed by the release of standard design drawings.
He said in a statement: "In future public works projects using solar street light components, we hope to use solar lighting, taking into account its stability, long life, ease of installation, safety, and of course energy efficiency, so that It makes it ideal for new and existing roads."

Solar street light technical requirement
The Minister of Public Works added that Department Order No. 19 will serve as a reference for the regional offices of the Ministry of Public Works, regional engineering offices, clusters of unified project management offices, and consultants of the Ministry of Public Works in preparing the design plan for road projects.
The technical requirements in the guidelines include: street lighting must be uniform, without dark bands or sudden changes; they can be high-pressure sodium (HPS) or LED solar lighting.
In addition, the color temperature can be varied between warm white and warm yellow, and the use of ultraviolet rays is prohibited; suitable for outdoor use, it has a degree of protection of IP65 according to IEC standards.

Solar street lamp design layout
As for major national roads, the Ministry of Public Works stated that the lighting arrangement can be single, axial, opposite, or staggered; secondary roads can use single, opposite, or staggered solar lighting arrangements; and tertiary roads can use single or staggered lighting arrangements.
The command also sets the wattage of solar street lamp, installation height, spacing, and poles according to road classification, width, and number of lanes, taking into account intersections and merged road sections that require higher lighting levels to ensure sufficient light sources on driving roads arm use.
