Land cost accounts for
60%
of CAPEX.
(Solar IT Company HAEZOOM)
Despite COP28’s UAE Consensus goal to triple renewables by 2030, the IEA finds current deployment trend to be 30% short on the goal. For solar, land is a key constraint—costing up to 60% of CAPEX—which drives up generation cost and leads to mass forestration.
High Land Efficiency, Low CAPEX
O&M cost decrease, LCOE decrease
Forestration Decrease, Installation in Urban Area Possible
SPIRALPANELS
The bottleneck behind solar power adoption is the large land that traditional single-layer PV system occupies. So we...
Stack 'em.
TRADITIONAL
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
Other stacked solar concepts 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 that use high-reflectance materials like aluminum and polymer mirror sheets. These reflection panels 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 applies a dual-axis active solar-tracking algorithm to control the rotation and movement of the reflective panels.
This algorithm maximizes 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
Iterative testing found that SpiralPanels model can yield up to 5-6x more electricity generation compared to traditional single-layer, even when considering land size and energy consumption.
40%
CAPEX Decrease
In installing a set region of PV panels, SpiralPanels model uses 4x less land, 40% less CAPEX, and yields 22.8% less LCOE even when considering additional components.
2.3X
Adoption of Solar Power across the world
According to Woo, C. K. (2024), SpiralPanels' LCOE reduction is associated with approximately a 2.3× increase in solar adoption, strengthening the feasibility of achieving the COP28 renewable energy target.
