12 Gen 1500 Vdc Solar Systems
[2016-01-12]. 1500 Vdc solar systems set to reduce overall Balance-of-System (BOS) and installation costs, especially for utility-scale solar farms. Higher-voltage systems enable longer strings, which allow for fewer combiner boxes, less wiring and trenching, and therefore less labor. Ohmic losses are also reduced.
According to a GTM research, installing 1,500 Vdc systems in place of now-standard 1,000 Vdc can lower costs by as much as $0.05 per watt – about 5% of the total cost of a utility-scale solar farm. These advantages make high voltage use seem like a foregone conclusion, but there are a few market and regulatory barriers to these systems, especially in the US where the 1000 Vdc standard has been regulated only since 2013.
