Hong Kong researchers have designed an agrivoltaic system that makes use of blockchain tech and sensible contracts to cut back uncertainty between PV system operators and grape farmers. The proposed system makes use of rainwater to wash photo voltaic panels and supply irrigation.
Scientists from The Metropolis College of Hong Kong has developed a novel system design for agrivoltaic initiatives in vineyards.
The researchers describe their findings in “Built-in techno-economic and life cycle evaluation of shared round enterprise mannequin based mostly blockchain-enabled dynamic grapevoltaic farm for main grape rising states in India,” which was just lately printed in Renewable Power. They are saying the brand new design of the system simpletates rainwater harvesting, with photo voltaic array tilt to comply with the course of rain. The system shops and reuses the collected water for irrigation functions.
Researchers use a round enterprise mannequin (CBM) based mostly on blockchain and sensible contract applied sciences to coordinate between PV system operators and grape farmers.
“The proposed system works even with out the blockchain configuration,” mentioned researcher Nallapaneni Manoj Kumar. pv journal. “However with the blockchain configuration, agrivoltaics work extra effectively with excellent coordination taking into consideration all of the uncertainties that come up between solar energy era and grape farming by way of co-location accessible that accessible as water for plant irrigation and photo voltaic panel washing.That is solely potential if the system is ready to monitor real-time climate and function mechanically by means of sensible contracts.
Lecturers use a sustainability efficiency, life cycle evaluation, and techno-economic (RePLiCATE) technique to display the multifunctional viability of the system in a number of grape producing states of India. They declare that the nation’s present laws for energy buy agreements (PPAs) don’t make agrivoltaics viable.
“Good contract helps in automating the agreements and gives a hyperlink to the power and grape buying and selling market,” they mentioned.
For the 1-ha “grapevoltaic” farm mannequin, the analysis crew thought of the vine–plot planning, photo voltaic PV configuration for the winery, plant water necessities contemplating evapotranspiration, rainwater harvesting potential, and power necessities for groundwater extraction. Modeling is concerned 1,458 rising crops in 27 rows and 504 kW PV set up organized in 14 rows. The system options panels with outputs of 100 W every and dimensions of 1,197 mm × 535 mm There’s a distance of 0.13 meters between the modules.
The panels have a floor that permits the free movement of water. Water can be utilized to wash the panels themselves or present irrigation by means of a drip system related to the storage tank.
Scientists say that the entire earnings generated by a 1-ha Grapevoltaic farm might differ, relying of electrical energy productions and grapes, electrical energy costs, and market costs of grapes. They are saying the proposed system can scale back water consumption for farmers and PV operators.
“Agrivoltaics generally is an effective resolution for grapes and higher and the grape has a shade tolerant potential however is extra delicate to climate occasions,” Nallapaneni mentioned. “To keep away from this we’d like such excessive technical programs that may hyperlink, for instance, the grape farm to the GrapeNet platform the place commerce laws and grape certifications might be accomplished with one click on. “
