About WRB Group

Northern Ireland's trusted solar and electrical contractors. Over 30 years providing premium renewable energy solutions and electrical services across NI.

Our Story

Founded in 1995, WRB Group began as a traditional electrical contracting business serving commercial and industrial clients across Northern Ireland. With over three decades in the industry, we built our reputation on reliability, quality, and professional service.

In 2010, recognising the growing importance of renewable energy, we expanded into solar installations. Since then, we’ve completed over 500 successful renewable energy projects, helping homes and businesses across NI reduce their energy costs and carbon footprint.

Today, WRB Group combines traditional electrical knowledge with modern renewable technology. From residential solar installations to large commercial projects, we deliver complete energy solutions backed by strong local knowledge and support.

Meet the team

Hugh McManus Managing Director

I have been with WRB for 4 years and have over 15 years in the renewable energy sector.

I strive to provide the best care before and after installation and will help with grant applications.

I will commit to site visits and phone calls, whatever is needed, to talk through the benefits of solar PV and what type of system will work best for your personal needs.

Climate change is a concern for us all and with rising costs, there has never been a better time to invest in your future.

These panels are European made and come with a 30-year Performance Warranty. They are the latest half cell technology. Implementing half-cut cells in solar panels can help improve the power output of a solar panel system. Half-cut solar cells are exactly what their name suggests – they are traditional silicon solar cells that have been cut in half using a laser cutter.

Since the cells are physically smaller, they are more averse to cracking.

A half-cut cell carries half the current and a quarter of the resistance of a full cell. So a complete half-cell module has the same current but half the resistance of a regular module. Resistance = wasted power, meaning a half cell solar panel can boost output by around 3%.

A regular panel is made up of 3 rows of cells connected in series with bypass diodes. If one cell is shaded, a third of the panel’s output can be lost. But in a half-cut panel, there are 6 rows of cells. So, if one of the cells is shaded, only a sixth of the output is lost.

With a lower current in each cell, there’s less heat concentration.

 Roof space can be saved using half cell technology.
