The research demonstrated significant efficiency
improvements in solar-driven hydrogen peroxide production,
combining biological mimicry with photocatalytic applications to
advance solar energy harvesting technology (Qin et al., 2021).

Design and Development of Smart Flower PV System

A compact solar energy system is modelled after sunflowers and
their heliotropic movement (natural sun-tracking). The panels are
arranged in a petal formation around a central axis, offering two
key benefits: increased power generation in a smaller footprint and
visual appeal. The micro-scale prototype measures 18 inches tall
(with petals extended) and 14 inches in both length and width, as
shown in Figure 44.

The data was gathered through a comprehensive review of
recent literature examining sunflower-inspired solar tracking
systems. The analysis revealed substantial enhancements in solar
energy efficiency, with improvements spanning 18% to 90%
compared to traditional fixed solar installations. These gains were
accomplished through biomimetic tracking technologies and
cutting-edge system components. Research conducted previously
demonstrated that combining photovoltaic panels with thermal
energy collection systems, along with implementing Light
Dependent Resistors (LDRs) and microcontrollers for continuous
sun positioning, substantially increases energy capture rates. The
incorporation of self-bending polymers and light-responsive
hydrogels into solar tracking mechanisms also reduces
mechanical complexity while boosting operational efficiency.
Studies further examined dual-axis tracking configurations
utilising N-type mono-crystalline cells, achieving efficiency rates
up to 24.3%. These sunflower-inspired designs offer compact and
flexible characteristics that enable deployment across diverse
settings, including residential installations, commercial facilities,
and agricultural environments.
