Vertical bifacial photovoltaics – A complementary technology for the European electricity supply?

Value of bifacial photovoltaics used with highly reflective ground materials on single‐axis trackers and fixed‐tilt systems: a Danish case study

“…Therefore, the value of the energy generated by the six systems is not estimated and compared solely based on hourly Nord Pool Spot power market prices and income. We additionally use the value factor ( VF ) as used in [31, 43], which is the ratio of the income generated by a specific PV system relative to the average spot price during the period analysed the following equation: Derivations of the VF numerator and denominator are shown in (2) and (3), respectively. In (2), is the calculated hourly spot price ( P t ) weighted according to the hourly electricity ( E t ) generated by a given PV system.…”

“…Bifacial PV and HSAT technologies – whether used individually or together – offer the possibility to shift peak production to match times of peak demand. Investigations to this end have been conducted for vertically mounted east‐west facing bifacial systems (VBPV), and their potential to match supply and demand profiles, stabilise the grid and increase self‐consumption [29–31]. Simulations performed by Van Aken [32] have shown that bifacial on HSATs can generate more revenue per watt peak than VBPV in climates with both low and high fractions of diffuse irradiance.…”

Marginal Effect of Variation in Photovoltaic System Configuration's Generation Profiles on Price Stabilization in the Netherlands Compared with Deployment of Flexible Demand and Supply

“…[ 5 ] A study by Chudinzow et al shows that in some scenarios the price per MWh of solar electricity in the market will decrease even faster with increased deployment. [ 6 ] In contrast, Chesser and co‐workers describe how increased electricity generation and local storage by consumers leads to increased consumer prices, as the fixed costs for the centralized generation and transport have to be recovered by a smaller market volume. The higher consumer prices will lead to more consumers to generate a larger fraction of their electricity consumption themselves, yielding a positive feedback loop in favor of more, distributed generation for self‐consumption.…”

Enhancing the Value of Solar Electricity as Solar and Storage Penetrations

“…Alternative PV system configurations can shift the timing of solar production, although many studies of this approach focus exclusively on plant costs without connecting the shifted production to changes in grid value [6][7][8][9][10][11][12]. More recent studies use wholesale market prices or power market simulation models with a limited set of standalone PV plant configurations-including changes to tilt, azimuth, and solar tracking device-to show that shifting production timing can marginally increase grid value [13][14][15][16][17][18][19][20]. Some of these studies conclude that the value-maximizing azimuths for PV are increasingly westward as solar penetration increases [18,19].…”

“…The four primary contributions of this study relative to the existing literature are: (i) we consider a broader range of PV options in a unified framework, (ii) we evaluate configurations with and without energy storage, (iii) we quantify the benefits of PV participation in ancillary service (AS) markets, and (iv) we utilize a larger and more granular dataset on historical and projected wholesale prices with increased solar penetration. While most previous studies focus on one or two configuration options [6][7][8][9][10][11][12][13][14][15][16][17]20] and the more comprehensive studies assess a few configuration options [18,19], our analysis considers more than ten options. We compare existing PV plants with grid-friendly PV options ranging from simple tilt and azimuth adjustments to vertical bifacial modules, provision of ancillary services, and addition of energy storage.…”
