Thin Film Solar Modules
Thin Film solar cells are made from depositing very thin layers of photovoltaic materials "film" onto a conductive backing. Each layer of film absorbs a separate spectrum of light and combine to form a solar cell. This manufacturing process makes these solar cells extremely thin and flexible allowing them to be installed on curved roof surfaces or in calculators.
- Lower cost to manufacture.
- Improved low light performance due to being able to absorb a larger portion of the spectrum.
- Much lower efficiency.
- Large space requirements for similar power yields to silicon solar technologies.
- High operating voltages prohibit micro inverter use and limit string sizes.
All 4 Thin film modules on this project are connected to a Fronius Galvo string inverter. Due to high operating voltages, Thin Film modules cannot be connected to micro inverters.
