Sungrow has announced that one of its 1500V PV projects was successfully connected to grid, officially initiating the next phase of the project. With a total of 30 MW installed capacity, the project uses mixed systems combining both 1000V and 1500V. In comparision to the 1000V system, the 1500V system is capable of reducing nearly 20 per cent of cable costs, leading to a lower cost of roughly $US 3 cents per watt. The increase to direct voltage at 1500V helps to improve efficiencies, by allowing more modules to be connected in every string and reducing the amount of cabling. This in turn, leads the system to be improved by more than 1 per cent.
