Photovoltaics TRIZ Cases
- Multilevel Power Converter Control With Estimated Input Voltages
Estimated input voltages let a master controller coordinate multilevel converter switching at high frequency with fewer sensors and lower losses.
- LED-Lit Photovoltaic Array With Prism Reflectors for Night Power
Internal LEDs and prism reflectors keep photovoltaic cells illuminated after dark, extending power generation without external charging.
- Mobile Solar Panel Cleaning for High-Pressure Dirt Removal
A mobile cleaner combines high-pressure water and frictional scrubbing to remove solid dirt and prevent edge buildup on solar panels.
- PV Combiner Box Protection Switch for Fast Short-Circuit Isolation
A release-triggered protection switch isolates a shorted photovoltaic unit faster than fuses, protecting lines and cutting cable cost.
- Cholesteric Liquid Crystal Waveguide for Selective Light Reflection
Stacked cholesteric liquid crystal layers in an optical waveguide tune selective reflection bands to improve reflectance and suppress scattering.
- Thermoelectric Nano-Jet Cooling for Uniform PV Cell Temperature
Pulsating nanofluid crossflow and local jet cooling lower PV cell temperature while improving thermal uniformity and power generation.
- Solar Array Reflector Layout for Higher Rooftop Power Density
Angled wedge reflectors redirect sunlight onto vertical solar cells to raise rooftop power density and shorten residential payback periods.
- PV Panel Power Tapping for Solar Tracker Controllers
Directly tapping PV panel output powers controllers and motors without grid wiring or battery charging, simplifying solar tracker power supply.
- PV String Curtailment Control With Selective MPPT Tracking
During curtailment, selected PV strings keep MPPT active while others stay power-limited, preserving optical power data and grid stability.
- Framed Solar Panel Structure for Wire Insulation and Impact Resistance
A rigid frame, insulation plate, and adhesive films protect cells and exposed wires to improve impact resistance, safety, and panel life.
- Portable Solar Battery Transfer for Plug-and-Play Home Power
A movable rechargeable battery links solar panels and an inverter, avoiding fixed wiring and making home solar power easier to install and use.
