Romag | Quality British PV

Romag are the only UK owned company currently manufacturing solar PV panels in the UK.

With a 70 pedigree as a specialist glass manufacturer, making everything from building  to bullet proof glass at their factory in County Durham.

Romag have been manufacturing solar panels since 2004, but have drastically revamped their quality control, product range and pricing policy recently to the point where they can now offer panels that are of a quality to match the best European manufacturers but at prices that are competitive with the panels coming out of China.

Key quality control improvements at Romag include:-

• £2 million electro-luminescence testing machine to check the quality of solder joints and cell integrity.

• Flash testing and sorting of all cells, and cell strings prior to assembly.

• Automated soldering process and assembly lines.

Romag also manufacture solar slates and building integrated PV, including the transparent glazed panels recently used in the multi-million pound redevelopment of Kings Cross Station's historic roof.
