Msanidi programu wa Ujerumani BEC-Energie Consult ameunda mfumo wa kupachika ambao unatumia nyenzo kidogo kuliko mifumo ya kawaida. Inadai teknolojia mpya inaweza kufikia MW 1.45 za pato kwa hekta. Inaweza pia kutumika kwa mifumo ya agrivoltaic ya kiwango cha chini.
Germany-based solar project developer BEC-Energie Consult GmbH has developed a self-supporting mounting structure for ground-mounted PV projects.
The company said it is now testing its patented “BECU” system at a 7 MW pilot facility in Sonneberg, Germany.
“The core idea of the patent is to exploit the self-supporting capacity of the photovoltaic module frame through the simplest, most stable, low-maintenance and space-saving installation possible in rows or blocks,” the company said.
The structure is south-oriented, with an incline of 9 degrees to 10 degrees.
“The holder reinforcing bar system, which leaves a gap of between 10 cm and 20 cm between the rows of modules depending on the design of the holder, consists of a galvanized reinforcing bar and 10 specially developed module holders,” said BEC-Energie Consult.
The reinforcing bars are driven into the ground up to 1.3 meters deep using a ram or caulking hammer, depending on the quality of the soil.
BEC-Energie Consult claims that its transport costs are lower. It said that its structures could also be used in ground-level agrivoltaic projects, if designed appropriately.
Livestock could be kept below the modules, said BEC-Energie Consult. It is now working on enabling ground-level vegetable cultivation with the help of small, autonomously operating robots.
In a classic ground-mounted system with the “BECU” substructure, system owners could achieve 1.45 MW of output per hectare, according to the company. For ground-level agricultural PV systems, 1.2 MW per hectare could be achieved.
