Application and delivery services

Sunna Design Support Proven Through Site Decisions

Services connect survey inputs, photometry, autonomous-energy assumptions and installation constraints to a reviewable release package.

Outdoor lighting engineer surveying a roadway

Four disciplines around one site

Site intake

Coordinates, road classification, pedestrian activity, operating hours, mounting limits, wind exposure and access conditions establish the design boundary. For autonomous solar systems, shading and local solar resource are recorded before hardware is shortlisted.

Photometric coordination

Current IES or LDT data is applied to actual pole spacing, mounting height, setback and target plane. Average illuminance alone is insufficient; uniformity, vertical light, glare, BUG rating and spill at boundaries shape acceptance.

Energy and autonomy review

Load profile, dimming schedule, solar resource, module orientation, battery capacity and temperature assumptions form an energy balance. A nominal panel wattage cannot prove year-round autonomy without a defined location and operating strategy.

Delivery documentation

Drawings, configured bills of material, installation notes and market-specific UL, CE or RoHS evidence are assembled for the selected system. Commercial dates and warranty terms remain governed by authorized documents.

Illustrative decision paths

Roadway pole spacing model

Roadway spacing review

A preliminary layout uses uniform pole spacing despite changes in intersection width and pedestrian crossings. The review divides the corridor into calculation zones, applies current candela distribution and records exceptions for conflict areas. The outcome is a traceable layout basis, not a fabricated accident-reduction claim.

Remote solar path review

A path requires dusk-to-dawn operation where grid extension is impractical. The team compares local irradiance, seasonal load, dimming profile, shading, battery temperature and maintenance access. Autonomy is expressed against stated inputs; it is not generalized to every climate.

Request a site decision review.

Provide drawings, coordinates, operating schedule and the unresolved selection question. Identify the civil, structural, electrical and commissioning owners so unresolved dependencies remain visible.
