CdTe PV Modules Vs. Silicon PV Modules
A Technology Comparison
The Silicon Problem
The average Silicon production cycle requires roughly 5 manufacturing plants and immense labor and energy.
Silicon Modules are sensitive to heat, hail, and cell cracking.
CdTe vs. Si
CdTe Advantage over Si Modules
- Silicon PV cells are fragile, crack very easily and are subject to heat overload failure- even on cool days.
- More than 90% of Silicon PV Solar cells are made in China.
- Silicon PV semi-conductors are sensitive to mild heat, and are NOT well aligned with the Sun’s light spectrum.
- Silicon PV modules are subject to global semi-conductor shortages.
- Silicon PV is reliant upon forced labor.
- Silicon requires large amounts of electricity to manufacture.
- Silicon PV manufacturing uses ‘dirty’ energy derived from coal.
Higher Power Longer Life
CdTe has the longest lifespan, requires less installed kW's (Kilowatts) of installed power, and generates more power per year than Silicon PV modules.
Toledo Solar’s sleek black panels are fabricated using two sheets of high-strength tempered glass hermetically laminated in a frameless construction.
By contrast, silicon panels typically comprise many parts soldered together that are easily damaged by wind, hail, transport, installation and frequent cleaning in the field.
Thin-film CdTe panels are 100% recycled in a special-purpose facility, with over 90% of all materials being reused, whereas silicon panels are mostly scrapped in local landfills, creating a major hazardous waste problem.
Silicon PV solar cells require 2.5 times more energy to fabricate and are not recycled. CdTe is 100% recycled on an end of life recycling program, and all modules are made from 99% recycled materials by weight.
CdTe means less need for as many installed kW's than Silicon = the fastest Payback Period in the industry.
The power output of silicon panels drops significantly as the module is exposed to warm temperatures. CdTe panels are far less affected by heat.
Toledo Solar panels are more efficient in humid climates.
CdTe captures more sunlight silicon, giving it more total useable power output over the course of a day.
