How can you decide whether using bifacial outweighs the extra investment?

There is a few cents price gap between mono perk and bifacial modules. Manufacturers are working on reducing the price gap through several tools. Obvious methods like increasing bifacial production and manufacturing technology enhancements are two necessary focuses. The total production cost is partially resulting from producing the bifacial module’s backside. The technology is not new but only recently commercialized.  

The million-dollar question is, whether the increased energy production sufficient to cover the extra price? The response is complicated. While the raised cost of tools and setup prices of bifacial PV plants are not disproportionate, there are other variables. There are design elements specific to bifacial systems that contribute to more significant general installment expenses. The primary consideration is the backside of the modules. It is challenging to accurately predict the enhanced result for a system layout because of the many variables that affect back side manufacturing.

“Integrity is choosing courage over comfort; choosing what is right over what is fun, fast, or easy; and choosing to practice our values rather than simply professing them.”

A new thermodynamic formula reveals that the bifacial cells making up double-sided panels generate on average 15% to 20% more sunlight to electricity than the mono facial cells of today’s one-sided solar panels. The formula considers different terrain, such as grass, sand, concrete, and dirt. The formula developed by two Purdue University physicists can be used by EPC’s and investors for calculating in minutes the most electricity that bifacial solar cells could generate in a variety of environments, as defined by a thermodynamic limit.

“The formula involves just a simple triangle, but distilling the too complicated physics problem to this elegantly simple formulation required years of modeling and research. This triangle will help companies make better decisions on investments in next-generation solar cells and figure out how to design them to be more efficient.

It is essential to keep in mind that we are searching for the optimal “Levelized Cost of Electricity” (LCOE), not the maximum power feasible. There are numerous ways to boost power production, but many of these options are not cost-effective. Dual-axis tracking can increase power production, but it is pricey, and many moving parts are adding to complexity for O&M management.





A significant obstacle for bifacial modules in the marketplace is producing precise simulations satisfying financial questions regarding the additional costs. Enhanced testing and advanced modeling have been underway for many years. Improvements in irradiance, as well as geospatial information, have added significantly to renovations in these simulations. Bifacial test sites were constructed, doing research, and bifacial installations were completed producing energy and supplying actual data.

Some suggestions to enhance your bifacial installation and attain increased ROI and reduced LCOE consider some of the following: Your site location where land is cheap, bifacial modules can have optimum spacing resulting in greater yields. Additionally, bifacial gains are more significant where the diffuse light power is better, which means at higher latitudes, the bifacial return will be above at lower latitudes. Desert sand is a good option. The best alternative is white concrete or very reflective roofing aluminum foil. Snow and also ice also has exceptionally high reflective power. Height of the ground, tilt, row distance, to name a few more. If conditions fit the returns, the bottom line will be better, overcoming the increased cost now there are no tariff advantages.
