Solar Basketball Court Lighting: Lux Targets and Pole Heights

What the source specification gets right

The original specification for this page carries four numbers that hold up in practice: 200 lux minimum average illuminance, 8–12 m mounting height, four-corner or six-point fixture arrangements, and 400–600 W of panel per fixture with 3–5 days of battery backup. Those are the right starting points. What the original page does not do is explain the rationale behind them or what happens at the edges — which is where court projects fail.

Illumination targets and uniformity

Treat 200 lux average maintained illuminance as the floor for recreational and training play, not the target for competition. Uniformity decides how a court plays as much as the average does. A court averaging 200 lux with dark corners at the elbows plays worse than one averaging 180 lux evenly, because players read the ball against contrast, not against a headline number. Ask any lighting designer for the uniformity ratio — average-to-minimum across the playing surface — and design to it.

The practical consequences for layout:

• Four-corner arrangements suit narrower courts and tighter budgets. Six-point arrangements buy uniformity on wider courts at the price of two more poles.
• 8–12 m mounting height is the working band. Below 8 m, glare control gets difficult even with good optics; above 12 m you pay for pole and lifting capacity the court does not need.
• High-CRI LEDs with anti-glare optics are functional here, not cosmetic: they keep the ball trackable and stop players from looking straight into the fixture.

Sizing the solar side from the worst week

Panel and battery are sized from the site's worst solar month plus the nightly runtime — never from an annual average. The method we run on court projects:

1. Fix the load first. Total fixture wattage × operating hours per night × nights per week, plus the control and monitoring overhead.
2. Size generation from the design month. Use the site's minimum peak sun hours for the worst month, not the annual mean. A court that runs four hours a night through a cloudy December needs an array sized for December.
3. Size the battery to the autonomy target. 3–5 days of backup is the range we spec: three days covers a normal cloudy stretch; five days covers that stretch plus margin. High-latitude winters and monsoon climates push toward the top of the range.
4. Match the controller to the array. This is where solar sports projects quietly lose energy — a high-voltage panel on a mismatched controller. Our MPPT vs PWM guide covers the rule; the short version is that modern high-Wp fixtures need MPPT.

The 400–600 W per fixture figure is the hardware envelope that method produces for a standard full court in most climates. A high-latitude or heavy-monsoon site sits at the top of that range rather than outside it.

What installation actually involves

Wire-free installation is the whole point: no trenching from the building to the court, no cable-route permits, no surface restoration. The poles go where the lighting design puts them, the fixtures bolt on, and the only civil work is the foundation. On existing courts — school yards, park courts, campus recreation — that difference is often the entire project decision, because trenching and restoring a court surface costs more than the lights.

Control runs autonomously: scheduled operation, dimming when the court is empty, and remote monitoring of battery state and fixture health, so the facility team sees problems without a site visit. Maintenance is panel cleaning and an annual connection check. The failure we see most often in the field is not a dead light; it is a battery sized from an annual-average sun-hours map instead of the worst month, and the symptom shows up as shortened runtime in the cloudy season.

Who this page is for, and its limits

This guide covers outdoor courts for recreational and training-level play. Competition venues carry photometric requirements — broadcast and officiating standards — that go beyond horizontal averages into vertical illuminance and glare rating; those need a site-specific lighting design, which we do per project rather than per page. For a first-pass array and battery size, start with our panel sizing calculator, then compare the all-in-one solar street light line we build courts from.

What this page still needs

This page carries design specifications, not a case study, because we do not publish numbers we cannot stand behind. Missing before it can carry a real project: at least one completed court with location, court dimensions, fixture count and wattage, pole heights, measured illuminance, operating history, and photographs. Until then this page stays a design-specification page — useful for writing an RFP, but not evidence of a delivered job. If you are evaluating a court project now and want references, ask us; we will connect you with completed installations directly.
