The truth is there are such a lot of tendencies to take a look at in 2022 that we have now to separate them into two articles. So, with out additional ado, listed below are our high three PV mission and software tendencies for 2022:
Hybridization
Photo voltaic-wind hybrid (SWH) tasks are a pattern in lots of components of the world, particularly these with congested grid connection processes or related wind and photo voltaic. peaks. The pattern in SWH tasks is probably finest exemplified in India and the US. One of many many causes India likes SWH tasks a lot is their capability to cut back renewable vitality uncertainties when the wind would not blow or the solar would not shine.
Bridge to India’s (BTI) managing director, Vinay Rustagi, mentioned that SWHs “have change into extra standard due to their easy energy output profile. We have seen a pattern. aka a trend aka a trend aka a trend A rising pattern is that utility and even massive company customers are preferring SWH over easy photo voltaic tasks regardless of the upper value. “
Jennifer King, a analysis engineer for the US Nationwide Renewable Vitality Laboratory (NREL), mentioned pv journal that SWS methods are an efficient instrument for avoiding transmission congestion.
“We could not be capable of make the transmission quick sufficient to achieve our decarbonization objectives in time,” King mentioned. “Hybrids are useful as a result of they supply a cheap (satisfactory) method to construct sub-optimal useful resource areas however not less than if there’s present transmission and keep away from grid congestion.”
Hybrids won’t solely enable builders to maximise their connection to the grid, however will enable extra renewables to stream nearer to the place mentioned vitality is used – the important thing to effectivity and stability in grid. Finally, King mentioned, “the restrictions of the transmission system actually drive hybrids. If the transmission system is absolutely established, we cannot want hybrids.
One other grid-congested and extra land-conscious continent, Europe, can be beginning to see the attraction of SWS methods. In Spain, one of many nations main the SWH push, the lure is offered by the capex financial savings gained by sharing the grid connection.
Additional north, in Denmark, and retrofitting of onshore wind farms with photo voltaic has begun. The top of public affairs at Eurowind Vitality, Joachim Steenstrup, spoke pv journal that the wind in Denmark doesn’t blow in July, however it’s observed that there isn’t any sunshine in January.
“They complement one another very properly,” Steenstrup mentioned. “If we had 100 MW of wind and 100 MW of photo voltaic sharing the identical 100 MW grid connection, the loss would solely be 8% (durations of overlapping era), and should you take a look at how beneficial is 8%, that is the worth subsequent to the left, as a result of wind and photo voltaic can be lively and due to this fact electrical energy costs will undergo the ground.
Hybridization just isn’t restricted to land, nonetheless, as this subsequent pattern will present.
Floating PV offshore
Floating PV (FPV) is now a well-established area of interest within the photo voltaic sector, however because the utility of FPV proves itself time and again, the enchantment of the open sea is stronger. In any case, there’s actually an ocean of house for offshore FPV to reap the benefits of, and due to mission builders pushing the boundaries, the coast is beginning to clear.
After all, offshore PV is of specific curiosity in nations that do not have a lot land to spare however loads of seashores to play with, such because the Netherlands, Malta, Japan and Singapore.

“In a spot like Malta a 20 MW, not to mention a 100 MW, photo voltaic park is unthinkable,” mentioned Luciano Mule’Stagno, director of the Institute for Sustainable Vitality and group chief of the Photo voltaic Analysis Lab in College of Malta. “However we will simply discover appropriate locations for a few of these marine vegetation. Mixed with the ever-decreasing value of vitality storage, I can see a spot like Malta operating on 100% renewables (FPV -plus-offshore wind) in 10 to fifteen years.
Since offshore FPV remains to be in its early phases, numerous designs are vying for supremacy, together with Norwegian-headquartered Ocean Solar’s versatile round floor membrane modeled after an enormous water lily, and a Dutch outfit which is SolarDuck raised triangular platform able to interlocking.
SolarDuck, along with its accomplice German utility RWE, launched the Merganser mission in 2022, a 500 kW pilot mission that goals to face up to winter storms within the North Sea. Though the mission remains to be ongoing, in November 2022 SolarDuck introduced that it had been chosen to construct a 5 MW offshore FPV mission with the Hollandse Kust West offshore wind farm within the North Sea.

Microgrid islands
Island microgrids are a rising pattern, particularly in distant areas on the finish of energy networks or components of the world vulnerable to pure disasters and unreliable grids. Photo voltaic-powered microgrids can present a neighborhood with larger stability and independence, permitting weak areas to not depend on distant era sources as demonstrated in recent times in locations like Australia and California because of fires, or Puerto Rico after hurricanes.
An island microgrid is a system of era (photo voltaic) mixed with storage that’s equally linked to the grid and in a position to place itself on an island. This functionality implies that communities can contribute their photo voltaic era to the grid, but when they fail the grid they aren’t left at nighttime.
For Jana Ganion, director of sustainability and authorities affairs for Blue Lake Rancheria (BLR), a federally acknowledged Native American tribal authorities situated in rural northern California, vitality conservation occasions within the state is understood to final for a number of days. Fortuitously, BLR is dwelling to a pioneering microgrid system that has demonstrated its price in a disaster repeatedly.
Based on Warda Ajaz, a analysis analyst at World Vitality Monitor who research microgrid adoption within the US, “disasters act as a big strain on the panorama for the adoption of microgrids within the US.” And never simply California wildfires both, as one among Ajaz’s interviewees mentioned concerning the New York College (NYU) microgrid in Manhattan: “One of many shining examples. [during Hurricane Sandy] when decrease Manhattan was darkish… NYU [microgrid] is the one one operating and working downtown. Lots of people are calling it the sunshine within the darkness of Sandy, rapidly individuals are beginning to take a look at it and say, ‘Hey, possibly it is a good resolution for our potential vitality points. -on.’ “
However relating to resilience within the face of hurricanes, there are few Puerto Ricans extra skilled. Within the aftermath of Hurricane Maria in 2017, and Hurricane Fiona in September 2022, Puerto Ricans are more and more turning to photo voltaic and now islandable microgrids.
As Puerto Rico generates 70% of its vitality within the south, however 70% of its inhabitants lives within the north, if a hurricane breaks the facility strains that traverse the island’s mountainous inside, outages will be extended. to repair. So why are neighborhood microgrids like the agricultural neighborhood of Castañer proving to be a testing floor for wider adoption and connectivity of microgrid methods.
This sense of Puerto Rico as a laboratory for grid redevelopment is not only a pleasant thought to place some optimistic gloss on a catastrophic state of affairs. The truth is, after the success of the Castañer microgrid throughout Hurricane Fiona, the US Division of Vitality determined to make use of the microgrid as a “dynamic laboratory” for the transmission and distribution supplier LUMA to observe how distribution works. Distributed sources assist restore energy after an outage.

Consisting of 225 kW of photo voltaic and 500 kWh of battery storage, the Castañer microgrid is a product of the neighborhood’s personal group and the New York-based Interstate Renewable Vitality Council’s (IREC) Interstate Renewable Vitality Accelerator Program, funded by the US Division of of Commerce Financial Growth Administration.
IREC Program Director Carlos Alberto Velázquez says the success of the microgrid system throughout Hurricane Fiona, not just for the 5 native companies it operates however the resiliency hub it created when the grid failed , that means that it “has already been recognized as an vital element of the brand new grid, albeit a small half, however sooner or later there can be a whole lot of those microgrids all through Puerto Rico.
