Why solar lighting is spreading now
Vision 2030 sustainability targets, and the rising cost of running cable to remote sites, have pushed many owners to ask about solar lighting poles. A solar pole carries its own power source — a panel and a battery — so it needs no cable trench and no grid subscription.
"No electricity bill," though, doesn't automatically mean "cheaper." Solar lighting is an engineering and financial decision that depends on site and use — in some contexts it is the smart choice, in others the most expensive option over the long run.
The components of a solar lighting pole
The solar panel converts sunlight into electricity during the day. Its capacity is measured in watts, and it must exceed the lighting load by a margin large enough to cover dusty and cloudy days.
The battery stores daytime energy to run the fixture at night. It is the shortest-lived part of the system and the most heat-sensitive. Lithium batteries (LiFePO4) have become the common choice because they tolerate more charge cycles than gel batteries.
The charge controller protects the battery from overcharging and deep discharge, and the LED fixture must be highly efficient because every watt saved shrinks the required battery and panel. Then comes the structure: the pole itself, which must carry the weight of panel and battery and the wind load on them.
Performance limits in the Kingdom's climate
Heat is the battery's enemy: battery performance and lifespan decline above 45°C. In a Saudi summer you must choose a battery with a suitable thermal rating and mount it in a ventilated box or low on the pole, away from direct radiation.
Dust reduces output: dust building up on the solar panel can cut its yield by 15 to 30% between one cleaning and the next. Any serious design adds a margin for this and factors in a periodic cleaning schedule.
Days of autonomy: a good system is designed to run two to three consecutive nights without enough sun. That margin raises battery cost — but it is the difference between reliable lighting and lighting that goes dark after one cloudy day.
When solar is the right choice — and when it is not
Suitable: roads and sites far from the grid, where the cost of running cable exceeds the cost of the solar system. Also gardens, walkways and parking lots, temporary sites, and projects that need fast execution without excavation work.
Usually unsuitable: highways that require high illumination levels and strict uniformity — a lighting load like that makes the battery and panel large and expensive. Also tall stadium masts, where the concentrated floodlights exceed what a solar system can practically serve.
In dense urban areas, where the grid is already at the curb, grid connection usually stays simpler and cheaper. The practical rule: the farther the site is from the grid and the lower the required lighting load, the more solar tips the balance.
How to evaluate a solar lighting quote
Don't compare solar poles on price alone — ask for the system details: battery type and guaranteed charge cycles, designed days of autonomy, panel wattage versus fixture load, and charge controller specifications.
Watch the warranty: the metal structure warranty is often separate from the electrical components warranty — battery and panel. Ask for the term of each part to be stated separately.
At Aktar we manufacture the metal structure for poles of every type, and work to match the solar system to each project's load. Send us the project site and the required operating hours, and our engineering team will return a written recommendation. The consultation is free and non-binding.
Frequently asked questions
Are solar lighting poles cheaper than grid connection?
Not always. Solar saves the electricity bill and the cost of running cable, but it shifts the cost to the battery and panel, which grow larger as the lighting load and the required days of autonomy rise. The practical rule: the farther the site is from the grid and the lower the fixture load, the more solar makes economic sense, while high-illumination roads near the grid are usually simpler and cheaper to connect to the grid. The correct comparison is made on life-cycle cost, not on purchase price alone.
How long does a solar pole battery last in the Kingdom's climate?
The battery is the shortest-lived and most heat-sensitive component; its performance and lifespan decline above roughly 45°C. That is why lithium batteries (LiFePO4) have become the common choice, as they tolerate more charge cycles than gel batteries, and they should be mounted in a ventilated box or low on the pole away from direct radiation. Actual life depends on battery type, guaranteed charge cycles, and cooling, and is determined precisely from the supplier's specification rather than a general estimate.
How many nights can a solar pole run without enough sun?
A good system is designed around what is called days of autonomy, typically two to three consecutive nights without enough sun. The larger this margin, the higher the battery cost, but it is the difference between reliable lighting and lighting that goes dark after one cloudy day. Added to this is a margin for reduced panel output from dust, which can cut yield by 15 to 30% between one cleaning and the next, with the appropriate figure set by a load-and-site calculation.
What should I ask for in a solar lighting quote?
Don't compare quotes on price alone; ask for the system details: battery type and guaranteed charge cycles, designed days of autonomy, panel wattage versus fixture load, and the charge controller specifications and fixture efficiency. Watch the warranty, since the metal structure warranty is often separate from the electrical components warranty for battery and panel, so ask for the term of each part to be stated separately. These details are what separate a reliable offer from one that looks cheaper and then fails early.
