A Japanese supplier brings new aluminum cables to the market for solar power systems



Japan’s GBP said its new cables comply with several international standards. It claims that the cables have an anti-theft function because they should prevent copper thieves from approaching the PV system.

The company claims that the advantage of the new product is an anti-theft solution, as aluminum costs significantly less than copper and aluminum cables are less prone to thieves than their copper counterparts.

GBP said the new aluminum cables are compatible with international standards 4 mm² x 95 mm², 4 mm² x 120 mm², 1 mm² x 150 mm², 1 mm² x 185 mm², 1 mm² x 240 mm², and 1 mm² x 300 mm².

“The conductivity of aluminum cables is about 60% of the conductivity of copper cables,” the manufacturer said. “But by choosing the right size, it is possible to achieve the same performance as with copper conductors. In addition, aluminum cables are 30-50% lighter and more flexible than copper cables, so they facilitate installation, reduce construction time and save labor costs.

GBP claimed that using its new cable could reduce the cost of a solar project by up to 10 percent. “It complies German standards,” the service provider said. “Anti-theft measures, such as our aluminum cables, also attract attention abroad.

Aluminum is cheaper than copper, but it is sensitive to oxidation. In addition, aluminum is also more brittle at normal temperatures and breaks more easily than copper.

In practice, aluminum cables are rarely used in small roof installations and are mostly used in large solar installations. These cables require a thicker cross-section than copper cables for the same output and therefore a little more space.
