Lighting and rooftop PV installations in eleven countries
Nineteen documented sites across South-East Asia, West Africa and North America: barangay and national roads, a river dike, sports parks, a Sahel corridor, desert town streets, industrial perimeters, and residential or resort rooftops. Open any card for the site constraint, the configuration and the photographs.
PH · Surigao del Sur
Tago River Dike Promenade
Barangay Purisima, Tago · flood-control dike used as an evening walkway
Site and requirement
The dike along the Tago River doubles as the barangay's evening walkway. There is no distribution line along the embankment, and trenching into a flood-control structure is not acceptable, so a grid-connected solution was ruled out early.
What was specified
All-in-one units with an integral panel, battery and driver on a single arm — no separate control cabinet and no DC cabling between pole positions. Poles sit back from the crest line so the walkway stays clear, and the luminaires run a dimmed standby level with motion boost to hold autonomy through consecutive overcast days.
Result
The promenade is lit end to end from pole-mounted units only, and the dike surface was left untouched.
PH · Lanao del Sur
Bubong Madanding Barangay Road
Barangay Bubong Madanding, Marantao · interior road with no utility line
Site and requirement
An interior barangay road in Marantao with no poles and no service drop. Residents needed light for evening travel and for security along the unlit stretch between sitios.
What was specified
All-in-one solar street lights on straight poles, spaced for continuous coverage rather than isolated pools of light. Battery capacity was sized for multi-day autonomy so the road stays lit through the wet season, and the units are sealed against dust and driven rain.
Result
A continuous lit corridor where there was previously no lighting at all, with no trenching, no transformer and no monthly utility cost to the barangay.
PH · Camarines Sur
Zone 4, Barangay Maydaso
Milaor, Camarines Sur · four-point community street installation
Site and requirement
A short community street in Zone 4 with a handful of households and a walking route to the highway. The barangay wanted a small, verifiable installation before committing to a longer corridor.
What was specified
Four all-in-one units on new poles, delivered as a complete package: foundation, pole erection, head mounting and commissioning. The photographs follow that sequence — excavated foundation, pole lifting, head alignment, then the lit street at night.
Result
Four points now cover the street and the junction, and the same specification can be repeated along the remaining length without redesign.
PH · Barangay Burgos
National Road Lighting
Barangay Burgos · highway frontage with continuous traffic
Site and requirement
A national road section through Barangay Burgos where traffic runs day and night. Roadway lighting here has to read as a continuous line, not a series of bright spots, and it has to survive vibration from heavy vehicles.
What was specified
A one-side pole line with consistent mounting height and arm projection, using cut-off optics aimed along the carriageway to keep light on the road rather than into adjacent lots. Brackets and fixings are specified for vibration, and the pole line follows the road edge so maintenance access stays off the travelled way.
Result
The corridor reads as an even ribbon of light at night, with the far side of the road still legible to oncoming drivers.
PH · Isabela
Barangay San Juan Roll-out
Cabagan, Isabela · 25 sets, pole assembly to commissioning
Site and requirement
A 25-set barangay roll-out along the road in Barangay San Juan. The scope covered the full sequence: poles staged on site, lifted and set, luminaires mounted and aligned, then commissioned before turnover.
What was specified
All-in-one units on straight poles, assembled at ground level and lifted in one piece — the method that keeps crews off ladders for head mounting and shortens the time each position is closed to traffic.
Result
Twenty-five positions completed in a single mobilisation, with pole line, arm direction and panel orientation consistent from the first pole to the last.
US · New Mexico
Santa Fe Arterial and Roundabout
Santa Fe, New Mexico · high-desert arterial with a roundabout approach
Site and requirement
A high-desert arterial where the nearest service point sits well outside the corridor. Trenching across the approach and the roundabout would have dominated the programme, so the lighting had to stand alone.
What was specified
All-in-one units with a top-mounted panel and side-entry arm, set back behind the shoulder line so the poles stay outside the clear zone. Optics are aimed down the carriageway so the approach reads before the roundabout rather than after it.
Result
The three photographs — daylight, dusk and full dark — show the same corridor lit with no change in pole position or aim.
US · California
Moreno Valley Sports Park
Moreno Valley, California · ballfields and perimeter paths on a hillside site
Site and requirement
A hillside sports park with ballfields, a parking edge and a path network, set well back from the nearest utility run. Lighting had to cover the field edge and the paths without a new service along the access road.
What was specified
Solar pole lights at the field perimeter and along the path network, with the higher mounting at the ballfield edge and lower units on the pedestrian routes. Each pole carries its own panel, so the layout can follow the paths rather than the grid.
Result
Field edge and paths are lit from the same standalone system, with no trenching on the hillside.
US · United States
Residential Walkway and Parking
Base housing · pedestrian paths, parking islands and landscaped courtyards
Site and requirement
Housing blocks set among parking islands and pedestrian paths. The brief was even, low-level light on the walking routes without spill into ground-floor windows.
What was specified
Solar pole lights on the parking islands and along the walkways, with the luminaire head shielded on the window side and the panel oriented to the prevailing sun. Mounting height is held constant so the path reads as one continuous line.
Result
Walkways and parking edges are lit at a consistent level, with the building facades kept largely out of the beam.
CA · Canada
Municipal Park Trail
Canada · park path network lit through dusk and into the evening
Site and requirement
A municipal park trail with no lighting infrastructure and no practical route for a new service. The path is used into the evening, including through the short-day months.
What was specified
Solar path lights on slim poles along the trail edge, with battery capacity sized for long winter nights and reduced solar input rather than for summer conditions. Enclosures and fixings are specified for freeze-thaw cycling.
Result
The trail holds a continuous line of light through dusk, with the poles reading as part of the park furniture rather than as street infrastructure.
BF · Sahel Region
Sahel Road Corridors
Sahel region, Burkina Faso · 1,095 IoT-connected units on a World Bank programme
Site and requirement
A dispersed road network across the Sahel, where the nearest service point can be hours from the next village and the maintenance cycle is measured in months rather than weeks. Dust, high ambient temperature and long dry spells set the durability requirement, and the programme asked for remote management rather than periodic site visits.
What was specified
An all-in-one unit — panel, battery, controller and driver on the pole — combined with an integrated IoT module. Dashboards carry live status, alarms and dimming control, while battery-health and energy data drive maintenance planning. Autonomy was sized against local weather records instead of a nominal figure, because a corridor that goes dark in the harmattan is worse than one that was never lit.
Result
The corridors are lit end to end with no grid extension and no control cabinet between poles, and faults surface on the dashboard before a crew is dispatched.
NE · Diffa Province
Diffa Province Street Lighting
Baroua, Ngagam and Diffa, Diffa Province · 1,750 split-type units for UNDP
Site and requirement
Three towns in south-east Niger close to the Lake Chad basin, where temperatures stay high all year and grid coverage is sparse. The lighting had to survive that heat without the battery cooking inside a sealed head, and it had to be serviceable without a platform.
What was specified
A split-type configuration with the battery mounted beneath the PV module — accessible from ground level for maintenance and out of easy reach for tampering. The system runs a 25.6 V low-current strategy to cut the heat generated in service, paired with LiFePO4 storage for high-temperature stability and an MPPT controller that derates above its rated ambient rather than shutting down.
Result
UNDP surveyed the completed installation and accepted the equipment, citing the brightness of the units and a 100% success rate across the delivered sets.
TD · Ouaddaï
Abéché Rural Road Lighting
Abéché, Chad · 165 all-in-one units, contractor-installed on a single-side layout
Site and requirement
A rural route with no grid connection. Lighting points were arranged on one side of the road, and the low-rise structures close to the carriageway constrained both where a pole could stand and where its panel would actually see daylight.
What was specified
165 all-in-one units on 7 m Q235 poles with 75 W LED heads, 12.8 V 90 Ah LiFePO4 storage and a 10 A MPPT controller, rated IP66 and IK08. The consignment shipped in a single 40HQ container thirty days after order. Installation was carried out by a local contractor, so the supply scope was limited to manufacture, delivery and the documentation the site team needed to build from.
Result
The single-side line was commissioned in October 2026. The photographs follow the work — pole assembly raised beside low-rise buildings, the base and cabling at the installation point, and the lit route after dark.
CI · Côte d'Ivoire
Industrial Zone Perimeter Lighting
Côte d'Ivoire · 14 split-type units around a solar plant site and its access routes
Site and requirement
An industrial plot that shares its boundary with a solar power plant. Lighting had to follow fenced perimeters and access routes while ground works were still running, so the pole positions could not be fixed to a completed landscape.
What was specified
A split-type APOLLO configuration at 40 W and 6000 K, with a 50 Ah / 25.6 V lithium pack and 5.8 m hot-dip galvanised Q235 poles, rated IP66 and IK09. Keeping the panel and the battery off the luminaire head allowed the pole line to follow the fence rather than a cable route.
Result
Perimeter and access roads are lit from standalone poles, with no trenching across the yard and no tie-in to the plant's own electrical system.
ZM · Zambia
Small-Town Trunk Road
Zambia · 50 all-in-one units on 6 m poles, installed by the client's own team
Site and requirement
A trunk road running through a small town with no lighting along it. The order came through an EPC contractor, and the town's own crew was to carry out the installation.
What was specified
50 all-in-one units on 6 m hot-dip galvanised Q235 poles. Because the installing team was not ours, the scope carried mounting details, foundation and torque drawings and commissioning notes alongside the equipment — the documentation is what makes a self-installed order work.
Result
The road through town is lit from pole-mounted units only. The day and night photographs show the same pole line before and after dark, which is the check that matters when the installation is done by someone else.
TH · Thailand
Pitched-Roof Residential Arrays
Thailand · flush-mounted arrays on tile roofs in residential streets
Site and requirement
Pitched clay and concrete tile roofs in built-up residential streets, where the usable area is broken up by hips, ridges and water tanks and the roof line is visible from the road. Arrays had to sit flat on the slope rather than on raised frames.
What was specified
Flush rail mounts fixed to the purlins, with the array split into blocks that follow the roof geometry instead of being forced into one rectangle. DC cabling drops through the tile line to a wall-mounted string inverter, and the AC side ties into the existing consumer unit.
Result
The roof silhouette is unchanged from the street, and the array reads as part of the roof covering rather than an addition bolted on top of it.
PH · Philippines
Residential and Resort Roofs
Philippines · metal and concrete roofs across residential and resort sites
Site and requirement
A mix of roof types on one programme: painted metal roofing on houses and outbuildings, and flat concrete decks on resort blocks. Salt air and typhoon-season wind load set the fixing specification.
What was specified
Penetration-free clamps on the metal roofs where the seam allows it, and ballasted or chemically anchored frames on the concrete decks. Arrays are kept clear of the ridge and the drainage falls so water still sheds the way the roof was designed to.
Result
Arrays on both roof families feed the site distribution board, with cable runs kept inside the roof space where one exists.
PH · Philippines
Subdivision Rooftops
Philippines · hip roofs and townhouse rows in gated subdivisions
Site and requirement
Hip roofs on detached units and long townhouse rows, where neighbouring buildings shade each other for part of the day and roof planes face four different directions.
What was specified
Arrays concentrated on the least-shaded plane, with string design that tolerates partial shading rather than losing the whole row. On flat sections the modules sit on low frames tilted to the prevailing sun; on hip roofs they follow the slope.
Result
Each unit runs independently, so a shaded roof on one house does not drag down its neighbour.
MY · Malaysia
Terrace and Bungalow Roofs
Malaysia · clay-tile terraces and detached houses with car porches
Site and requirement
Linked terrace houses with narrow roof planes, and detached units with a car porch roof that can take a separate array. High humidity and heavy afternoon rain drive the earthing and connector specification.
What was specified
Clay-tile hooks on the terrace roofs and a raised frame over the porch, with IP68 connectors, UV-rated cable and a bonded earth run back to the main board. Cable trays follow the roof edge instead of crossing the tiles.
Result
Both roof areas contribute to one inverter, and the porch array stays accessible for cleaning without walking the main roof.
VN · Vietnam
Rural Rooftop Array
Vietnam · a single large roof plane on a rural house
Site and requirement
A detached rural house with one long, unshaded roof plane facing the sun — the simplest case in the set, and the one where array layout matters least and fixing quality matters most.
What was specified
Modules laid in continuous rows across the full plane, wired in two strings so a fault isolates half the array rather than all of it. The inverter sits under cover at the gable end, out of direct sun.
Result
The whole roof plane is productive, and the array stays walkable at the edges for inspection.
