LTi REENERGY I VENDOR VIEW
Largest English solar plant: high efficiency factor ensures success
It took just eight weeks to build the largest solar power farm in England which supplies over 7,500 households with power. The plant near Wymeswold, close to the city of Nottingham, is highly efficient, and central inverters from LTi ensure maximum efficiency and continuous availability.
England is currently experiencing a solar boom. Solar modules with an output of 520 megawatt were installed in the first quarter of 2013 alone. The most spectacular project is based on the site of a former airfield that is now used as a public racing track. Six different open spaces between roads accommodate a solar power plant with 130,000 solar modules and a 33 megawatt output. Cost came to approximately 35 million pound.
At the behest of SAG, the German company LTi developed the inverters for the plant which play a key role in converting the resulting energy into alternating current. A total of 24 PVmaster stations are used with an AC output of 1.22 megawatt each. In addition to a medium-voltage transformer and medium-voltage switchgear, each station includes four PVmaster central inverters.
The crucial element is their efficiency factor of over 98 percent – an outstanding value that guarantees maximum electricity feed-in and a rapid return of investment. The installation is also very robust, because its power electronics are liquid-cooled very efficiently in a closed circuit. For planners, investing in LTi technology turned out to be a particularly smooth solution as the PVmaster stations are compact ISO containers that can be shipped to England easily and take up little space.
A VPN internet connection is used to monitor how efficient this technology is working, and the installation is controlled from the office. The planners are satisfied – this solution is highly efficient and future-proof, an important contribution to the alternative electricity market in England.
