iPyramid™
Capture More Sun

Quadra Solar is a concentrated solar systems technologies development company. We are developing iPyramid™, a Concentrated Photovoltaic and Thermal (CPVT) system for the flat rooftop market which has the following benefits:

  • Highest PV Efficiency of 32.2%.

  • Dual Energy System: demonstrated PV and Thermal efficiencies of 32.2% and 30.5% respectively and to reach 35% each.

  • Triple Usage System: Power, Heating & Cooling for both summer & winter use. Perfect for hot climates and cold ones like in Canada.

  • 3 to 6 times the overall efficiency of PV panels.

  • 2 to 3 time the overall efficiency of other CPV systems.

  • Outperforms all competitors systems in the locations where they work & works in locations where they fail (like Canada & north of 40 parallel).

  • Lowest kWh cost.

How we Acheive Higher Overall Efficiency

Quadra Solar is designed to offer the best Overall Efficiency, 3 to 6 times higher than our panel or CPV competitors.
To calculate the Overall Efficiency of a solar system, more than just PV module efficiency must be factored in. We have broken the Overall Efficiency down to 7 efficiencies, 3 conversion efficiencies and 4 non-conversion ones.

The conversion efficiencies are:

  1. Light Type Efficiency: Global (100%), Direct (62.7%) or Diffused (37.2%). An average of 120 cities worldwide.

  2. PV Efficiency: The efficiency of converting sunlight to electricity.

  3. Thermal Efficiency: The efficiency of converting sunlight to thermal energy.

The non-conversion efficiencies are represented by:

  1. Tracking Energy Efficiency: 100% for tracking solutions & 66.4% for stationary ones. 

  2. System Tracking Efficiency (No Shade Efficiency): represents the efficiency of a system in tracking the sun. Shading is the main factor here.

  3. Space Efficiency: the area of the surface capturing the sunlight divided by total area used.

  4. Weather Efficiency (for cold climates): the percentage of total up-time factoring in downtime in sun capturing due to snow falls and snow cover (accumulations).

Below is a summary table for the 7 efficiencies for different technologies.
