Autonomous Off-Grid Solar LED Lighting System Design
Pain Points (Public)
Off-the-shelf outdoor solar lights frequently fail to balance energy harvesting with storage capacity, leading to insufficient lumen output or premature shutdown before completing a full 10-hour nighttime cycle, particularly when constrained to custom form factors and low-voltage 12V DC operation.
Suggested Approach (Public)
Deliver an end-to-end off-grid hardware design integrating solar panel sizing, LiFePO4 or lead-acid battery management, an MPPT or PWM charge controller with low-voltage cutoff, and a high-efficiency constant-current buck/boost LED driver calibrated to sustain 5-8W continuous output over 10+ hours.

Opportunity assessment PRO
Development brief PRO
- Position as a specialized hardware prototyping service rather than a SaaS tool, directly bidding on custom outdoor lighting requests requesting 12V DC power architecture, round 8-10 inch solar panels, and 24-inch 5-8 watt LED fixtures.
-
- Build a reference 12V DC schematic in KiCad including an integrated MPPT/PWM charging controller and constant current LED driver circuit.
