Signify's Philips SunStay all-in-one solar street light with integrated LFP battery, solar panel and MPPT charger.
Philips SunStay from Signify is an integrated solar street light: the monocrystalline solar panel, lithium iron phosphate battery and MPPT charge controller are built into the luminaire, so no separate battery box or grid cable is needed.
Signify offers off-grid and hybrid versions, and battery capacity and panel size vary by model. The exact order code should be selected for the required light output and site conditions.

It depends on how much electricity you use, when you use it, and the space available. We review your electricity bills and loads during a site survey and size the system accordingly.
On-grid systems work with the utility supply and need no batteries. Off-grid systems run independently with batteries. Hybrid systems combine both, so they can keep essential loads running during power cuts. We recommend the right type after understanding your needs.
Yes. Panels still produce electricity on cloudy days, although output is lower than in full sunshine. Systems are sized with seasonal variation in mind.
Mainly regular cleaning of the panels to remove dust, and periodic inspection of connections, protection devices, inverters and batteries. We offer maintenance and inspection services.
