What Is a Solar Street Light Driver Card?
A solar street light driver card is a single printed circuit board (PCB) that integrates two critical functions into one compact unit: a solar charge controller (managing battery charging from the solar panel) and a DC-DC LED driver (powering the LED luminaire from the battery). Combining both functions on one card eliminates the need for two separate components — reducing cost, wiring complexity, and assembly time.
Systellar manufactures two variants:
- MPPT Solar Street Light Driver Card — synchronous buck converter, >95% conversion efficiency, dual LED driver output up to 60W. Ideal for premium and high-wattage solar street lights.
- PWM Solar Street Light Driver Card — 3-stage charging, 9W–45W range, 12V 5A / 8A models. The cost-effective choice for standard solar street light assemblies.
MPPT Solar Street Light Driver Card >95% Efficiency
The MPPT driver card uses a synchronous buck converter MPPT topology — the most efficient charge controller architecture available — to deliver over 95% conversion efficiency. It features a dual LED driver output supporting up to 60W total LED load, making it suitable for high-wattage integrated solar street lights where maximum battery runtime and luminaire output both matter.

Frequently Asked Questions
What is a solar street light driver card and how does it work?
A solar street light driver card is a combined PCB that integrates a solar charge controller and a DC-DC LED driver on a single board. The charge controller section manages charging of the battery from the solar panel — using either MPPT or PWM algorithms. The LED driver section converts the battery’s DC voltage into a constant-current supply to drive the LED luminaire.
By combining both functions on one card, assemblers eliminate two separate components, reduce wiring, and simplify luminary assembly. Systellar’s driver cards use terminal block connectors throughout — no soldering required.
What is the difference between MPPT and PWM solar street light driver cards?
The MPPT driver card uses a synchronous buck converter MPPT algorithm achieving >95% conversion efficiency. It also features a dual LED driver output supporting up to 60W — suitable for premium and high-wattage solar street lights (30W–60W LED). MPPT delivers more energy from the same solar panel, extending battery runtime especially during cloudy days or shorter winter daylight hours.
The PWM driver card uses 3-stage PWM charging (Boost, Absorption, Trickle) with >91% efficiency, optimised for the 9W–45W range. It is the cost-effective choice for standard and budget solar street light models.
Which battery types are compatible with Systellar driver cards?
Both the MPPT and PWM driver cards support LiFePO4 (Lithium Iron Phosphate), Li-ion (Lithium-ion), and Lead Acid batteries. The battery chemistry is programmable — the card is configured at the factory to deliver the correct charging profile (end-of-charge voltage, absorption voltage, trickle voltage) for each chemistry. The same driver card SKU works across all battery types in your product range.
Do the driver cards support PIR motion sensor dimming?
Yes. Both the MPPT and PWM driver cards support dimming using either a PIR (Passive Infrared) sensor or a Radar sensor. When no motion is detected the LED dims to a lower programmed intensity. When motion is detected the LED brightens to full or a higher programmed level. This extends battery backup duration significantly and is required in most MNRE-aligned solar street light specifications. Dimming level and sensor type are selectable during commissioning.
What LED wattage can these driver cards support?
The MPPT driver card features a dual LED driver output with 18V–36V DC output range (factory set), supporting up to 60W total LED load. The dual output allows two LED arrays or a single high-wattage LED module to be driven from one card.
The PWM driver card is rated for solar street lights in the 9W to 45W range, with LED driver output also in the 18V–36V DC range (factory set).
Are these cards available for bulk and OEM orders?
Yes. Systellar supplies driver cards directly to solar street light assemblers, OEM manufacturers, EPC contractors, and distributors across India. Bulk pricing is available for orders of 50+ units. Custom configurations — battery chemistry profiles, LED driver output voltage, motion sensor parameters — are available for established OEM customers. Contact us at +91-9568004455 or email info@systellar.in for a quotation.
Can the driver cards be used in humid or outdoor luminary enclosures?
Yes. Both driver cards are designed and tested for use in high-humidity environments — suitable for installation inside outdoor solar street light luminary enclosures across all Indian climatic zones including coastal, high-rainfall, and monsoon-affected areas.
