40% efficiency
​
30+ years in aerospace
​
Performance degradation on hot days less than 10% of silicon PV
1000X concentration - greatly reduces required cell area
​
Gallium arsenide is expensive but only a small cell area is needed
Silicon PV needs 166,400 sq.in. to produce 29.5kW we only need 56 sq. in.
High concentration enables efficient heat collection resulting in a 55% increased power production
​
Geothermal daily & seasonal storage - 90-95% efficient
Matches high summer production with high winter demand
Accuracy ±0.5° maximizes solar power output
​
Power feedback loop optimizes power and is self-correcting
​
Ease of installation and maintenance
Cogency’s product is transformational. The introduction of disruptive technologies generally involves high technical risk as an unproven technology is commercialized. Cogency, however, has designed its market-changing product by integrating four technologies with multidecade deployment histories. Their synergistic combination is novel and changes the terms of the solar marketplace but the risk of disappointing performance is minimal because the system components have demonstrated their viability for many years.
High Efficiency = Low Cost, High Areal Density
Our beta test systems have a net output efficiency of 66+%! PV panels have a net output efficiency on the order of 15%. Our production generators have efficiencies in the 70+% range. This high efficiency drives the cost down below fossils fuels and reduces land usage, which further reduces cost and enables most 1 or 2 story buildings to be powered on property carbon free.
GEOTHERMAL
01 / Geothermal Heating and Cooling
Geothermal HVAC (Heating Ventilation and Air Conditioning) systems is a proven technology with many thousands of installations worldwide. Our system consists of drilling bore holes into the ground 150 to 400 ft deep, inserting tubes filled with a heat transfer fluid to transfer thermal energy to and from the ground. Then heat pumps convert energy to cooling or heating depending on the needs of the building/facility.
02 / Thermal Storage
The earth makes a very efficient thermal battery. The thermal energy produced by our solar generator is stored in the ground using the geothermal ground loop. It be stored for use during non-sunlight hours or for many months for seasonal storage. For example in a cold climate heat is needed in the winter, but the most sunlight is in the warmth of summer. So in summer we store that heat in the ground to be used during the winter months. The round-trip efficiency is in the 90%-95% range compared to electrical battery storage of 75%-90%. And this thermal battery doesn’t degrade with time having a 50+year life.
