Both PV glass and solar thermal glass are solar glass, but they are exactly the same.
When choosing the solar glass, PV glass customers focus on Light Transmittance, while solar thermal customers care about Solar Energy.
Because they are solving two completely different problems.
PV modules = electricity generation
Only specific wavelengths can generate power.
Higher light transmittance = more usable photons = higher output.
While Solar thermal systems = heat generation
They absorb a much broader spectrum, especially infrared.
What matters is total solar energy transmission, not just visible light.
Simple takeaway:
PV = maximize useful light
Solar thermal = maximize total energy
The mistake we often see:
Using PV-oriented glass for solar thermal applications - which means lost efficiency without realizing it.
At Migo Glass, we help clients match the right glass to the right system - not just chase a single parameter.
Are you optimizing the right metric for your project?
