Overview

SOLIS NEXT — Integrated solar LED road lighting luminaire. SOLIS NEXT è un apparecchio stradale LED solare integrato: pannello fotovoltaico in silicio monocristallino, batteria LiFePO4, elettronica di regolazione e moduli LED SMD5050 in un unico corpo in alluminio pressofuso. Disponibile nelle configurazioni PRO ad alte prestazioni con controller MPPT e CORE bilanciata con controller PWM, ciascuna nelle taglie S compatta e L estesa. Pensato per strade principali e secondarie, piazze, percorsi e aree prive di cablaggio di alimentazione. This Centro Studi briefing does not replace the product page: it frames the luminaire within the design process, from requirement definition to on-site verification.

Where it is used

SOLIS NEXT belongs to the street lighting scope and is used in urban and suburban roads, roundabouts, pedestrian crossings and neighbourhood streets. Three items always come first: classification of the scope under the applicable standard, the real installation geometry (spacings, heights, brackets or pitches) and the maintenance conditions planned over the installation life cycle.

  • Strade principali e secondarie
  • Piazze e aree urbane
  • Percorsi pedonali e ciclabili
  • Aree senza cablaggio di alimentazione

Build characteristics

Photometric data: Specific photometric values (flux, efficacy, expected illuminance) are not published in generic form because they depend on configuration and installation geometry. Photometric files for calculation are available from the technical office at info@lumeitalia.it.

  • Monocrystalline silicon photovoltaic panel with 3,2 mm high-transmittance tempered glass
  • Panel service life over 15 years
  • Integrated LiFePO4 battery
  • SMD5050 LED modules with PC lens dedicated to road light distribution
  • Mechanical adjustment up to 180°
  • Photosensor: switch-on at dusk, switch-off at dawn
  • Timed management of power levels
  • SOLIS NEXT PRO with 3,2V MPPT controller, charging efficiency up to 95%
  • Photovoltaic panel power — 60 / 90 W
  • Conversion efficiency — 22 %
  • Battery — LiFePO4 3, 2V 60 / 90 Ah
  • Battery energy — 192 / 288 Wh
  • Light source — 80 / 160 LED SMD5050
  • CRI — >70
  • CCT — 3000 / 4000 / 5000 / 5700 / 6500 K
  • Charging time — approx. 4 (with sufficient irradiance) h

Regulatory requirements to verify

The requirement must be stated before product selection and repeated at commissioning with the same measurement method. A requirement written without a reference standard and without verification conditions is the most frequent cause of dispute at acceptance.

  • UNI 11248 — road classification and risk analysis
  • EN 13201-2 — performance requirements for M, C and P classes
  • EN 13201-3 — performance calculation method
  • Scope classified under the applicable standard, with the risk analysis attached
  • Performance requirements stated with standard, measurement point and conditions
  • Maintenance factor justified and consistent with the cleaning plan
  • Photometric files requested from the supplier for the design calculation
  • Ingress protection, impact resistance and electrical class matched to the site
  • Dimming system and control protocol defined in the specification
  • Warranty terms, spare parts and maintenance accessibility

Installation, operation and maintenance

During installation the main variables are aiming, tightening of the fixings and correct execution of the electrical terminations. In operation, the maintenance plan must state the cleaning frequency of the optical surfaces, periodic gasket checks and how electronic components are replaced.

In short

SOLIS NEXT is a defensible choice when street lighting requirements are stated, the calculation reproduces the real geometry and commissioning follows an agreed protocol. The full datasheet and quotation request are on the product page: https://lumeitalia.it/prodotti/solis-next. The technical office is available for design requirement reviews at info@lumeitalia.it.

Domande frequenti

Which projects should consider SOLIS NEXT?+

Street lighting projects covering urban and suburban roads, roundabouts, pedestrian crossings and neighbourhood streets. Suitability starts from scope classification and real geometry, not from datasheet comparison.

Which documents should be requested before specifying SOLIS NEXT?+

Photometric files for the proposed luminaires, declaration of conformity, declared lifetime data per IES LM-80 with its conditions, maintenance schedule and warranty terms.

Is SOLIS NEXT suitable for retrofitting an existing installation?+

It depends on the inherited geometry: existing spacings and heights must be checked with a dedicated calculation before confirming a one-for-one replacement. The technical office runs the check on request.

Why are photometric values not published?+

Because an out-of-context figure cannot be verified: the result depends on configuration, optic and installation geometry. Photometric files are available at info@lumeitalia.it.
