What is Bifacial PV?

Why is it Gaining Momentum & How Can EKO Help?

Bifacial Photovoltaic (PV) modules have nothing to do with face creams, skincare, or tanning; and everything to do with the future of solar power generation.

‘Bifacial PV’ modules are a type of solar panel designed to receive solar irradiance front and rear, generating power on both sides and, in a nutshell, that allows for new possibilities in solar power; alternatives to the conventional south orientation and latitude-based tilt optimisation of traditional projects.

New possibilities mean greater flexibility, greater power generation potential, and a great deal more excitement.

Indeed, the 2 Vs. 1-way power generation potential of Bifacial PV modules is helping to drive growth in PV power generation projects, despite reduced government incentives globally, with the ‘International Technology Roadmap for Photovoltaics’ predicting that Bifacial PV modules will represent 35% of the PV module market share by 2028.

This all sounds great, and indeed, with Bifacial PV you would naturally expect increases in yield and performance, however, there are uncertainties as to how much actual yield can be expected at each location. Like traditional PV projects, modelled yields and returns are needed to determine project scope, design, and to help secure financing.

That being the case, researchers around the world are working to define just how much additional power these new modules will make at different sites, under different sky conditions, and in different string configurations.

Performance monitoring of PV sites has for years required continuous measurements of the solar broadband irradiance, with instruments deployed in Global Horizontal Irradiance (GHI) and Plane of Array (POA) irradiance orientations. Now the added parameter of upward or reflected irradiance (RI) must be monitored too.

Enter EKO Instruments!

EKO Albedometers like the MS-80 are capable of being mounted in a traditional albedo measurement configuration, one sensor measuring the downward irradiance and another measuring upward irradiance; both levelled horizontally with the surface. And EKO is unique in the PV industry for its complete product line of research-grade equipment.

With EKO, researchers can source the sensors they need to study the true performance of bifacial PV modules. Get in touch to find out more.
