Land cost accounts for
60%
of CAPEX.
(Solar IT Company HAEZOOM)
Countris globally are signing agreements like COP28 to triple their renewable energy capacity. However, their current implementation speed is far slower than their goal (IEA). One difficulty in adopting renewable energy like solar power is the large land that it requires and the high generation cost that comes from land cost.
High Land Efficiency, Low CAPEX
O&M cost decrease, LCOE decrease
Forestration Decrease, Installation in Urban Area Possible
SPIRALPANELS
TRADITIONAL
The bottleneck behind solar power adoption is the large land that traditional single-layer PV system occupies. So we...
Stack 'em.
This is SpiralPanels.
An innovative solar power generation structure that combines three systems:
Multi-layer PV Panel, Reflection Panel, and Dual-Axis Active Solar Tracking Algorithm
01
Multi-layer PV Panels
Increase in PV Density
Increase in Land Efficiency
SpiralPanels stacks solar panels in multiple layers. Through this stacking approach, it maximizes the total panel area that can be installed within a restricted footprint.
02
Reflection Panel
Removal of Shadow
Maximizing Efficiency
Although similar stacked solar concepts have been proposed, they suffer from a critical drawback: upper layers cast shadows that significantly reduce the efficiency of lower panels.
SpiralPanels addresses this by integrating adjustable reflective panels—using high-reflectance materials like aluminum and polymer mirror sheets—that reposition throughout the day to redirect sunlight and maximize illumination across all installed layers.
03
Dual-Axis Active Solar Tracking System
Adjustment to Sun Altitude
Individual Lightweight Control
SpiralPanels model applies a dual-axis active solar-tracking algorithm to control the rotation and movement of the reflective panels, thereby maximizing the amount of reflected light directed to the solar panels on each layer as the sun’s altitude changes throughout the day.
Data-driven Impact
5-6X
Efficiency compared to single-layer
SpiralPanels experimented its prototype against traditional single-layer system and derived that it can yield upto 5-6x electricity generation, even when considering land size and energy consumption.
40%
CAPEX Decrease
In installing a set region of PV panels, SpiralPanels model occupies 4x less land, thereby reducing the CAPEX by 40%, even when considering additional components.
2.3X
Adoption of Solar Power across the world
40% CAPEX decrease leads to approximately 22.8% LCOE decrease. According to Woo, C.K. (2024), that leads to 2.3x increase in solar power adoption, making COP28 agreement a reality.
