How do glass windows affect this process.

Windows can be converted into solar panels by sandwiching nanoparticles between panes of glass which could make them useful in cities where space for solar panels may be limited.
Up against the glass unless its a skylight will not aim the panel properly toward the sun when it is above the horizon.
In addition to this some of the light is reflected meaning that a significant amount of power will be lost.
This will vary depending on the specific glass used as well as other factors but the power loss could be in excess of 50.
When the sun is above the horizon there will be reflection of incoming light at all of the surfaces of the window costing you power.
Whilst light does obviously travel through the glass some of this is blocked by the iron content in glass.

Placing solar panels behind windows will cost you quite a bit of energy.
Suntrica does not recommend charging behind a window glass or through a car windshield as they weaken the charging performance and the temperature might rise dangerously high for the.
By placing a solar panel behind a glass or a window you are eliminating the dni component of solar radiation that would directly impact the solar panel.
From the iron content of standard glass which blocks some light to low e glass which blocks some more light to the extra reflections from additional air glass interfaces you will lose a lot of power 50 or more.
