SOLAR 3D (3DPV) (3D-(3DPV))

Hexagonal Tesselation: Mathematically, hexagons are the most efficient shape for tiling a plane with the least perimeter. This reduces "wasted" space between cells compared to round wafers, though current manufacturing favors rectangles because they align with standard roof edges and silicon cutting processes.
3D Energy Capture: Your idea of "inward-facing triangles" suggests a 3D solar structure. Research into 3D photovoltaics (3DPV) shows that non-flat designs—such as cubes or towers—can double or even triple daily energy generation per unit of base area compared to traditional flat panels. These shapes capture more light when the sun is at low angles (sunrise/sunset).
Incidence Angle: The primary mathematical driver for efficiency is the angle of incidence. Peak energy is captured when sun rays hit the panel at a perpendicular (90°) angle. Your proposed geometry could theoretically maintain a "better-than-flat" angle for more hours of the day.

Solar Expansion in India & Saudi Arabia
You are correct regarding the massive investment and ideal conditions in these regions:
India's Solar Potential: India consistently receives approximately 300 clear, sunny days per year.
Capacity Growth:
India: As of early 2025, India surpassed 100 GW of installed solar capacity. By 2032, solar and wind are projected to drive two-thirds of the country’s power generation growth.
Saudi Arabia: The Kingdom is rapidly scaling, with solar capacity projected to reach over 52 GW by 2031. Long-term pathways for net-zero by 2060 include up to 151 GW of solar.
