Prism Solar and PPG Industries Partner to Test Performance of Anti-Reflective Glass in Standard and Holographic Solar Modules

Prism Solar Technologies and PPG Industries have partnered on a project to test the performance of different types of glass in both standard and holographic photovoltaic (PV) modules at various incident and direct angles. The test will compare PPG’s Solarphire® AR high-transmissive glass to patterned glass to determine the increase in energy yield.

Prism Solar will be characterizing the performance of PPG’s anti-reflective glass and patterned glass to determine the increased energy yield in relation to angular performance. By measuring energy yield from a series of modules characterized to be equivalent in terms of peak watt rating, it will be possible to determine the added value of anti-reflective properties for mono-facial modules as well as bi-facial Holographic Planar Concentrator modules. Test arrays with tilt angles from 0° to 90° will be explored to provide data on a full range of possible array tilt angles.

Increasing the energy yield of PV modules offers numerous advantages on the system level by reducing the number of peak watts needed to produce a given number of kWhs. The more kWhs generated per peak watt means a lower levelized-cost-of-energy (LCOE, or $/Wh) through reduced capital expenditure and a reduction in operation and maintenance costs for the system. Prism Solar is focused on producing PV modules with the highest energy yield per peak watt coupled with low cost.

This collaboration with PPG is one more step in enhancing the performance of PV modules by bringing PPGs strong science and engineering skills with glass and coatings to bear on the bright future of solar energy.
