Project Description:

Description : Solar PV fit out
Location : Co. Mayo, Ireland
Completed : 2021
Role : Solar PV Contractor
Scope : Design & Build of New Solar PV works.
Contract Value : £124,000.00

Key Features:

  • 362nr panels Installed
  • 150kW installed

WRB Group were proud to be appointed to the GAA Connacht Centre of Excellence. The GAA commissioned us to help them achieve their sustainability development in becoming green. We installed 148.42KW Solar PV on the main office building, which consisted of 410W JA Solar panels and Solis inverters. This project will reduce energy costs to help offset the running costs of the Dome, which is the largest Dome in Europe.

Heading here

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.

Durability

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

Lower resistive losses

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%.

Shade resistance

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.

Less chance of hotspots

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

Reduced installation area

 Roof space can be saved using half cell technology.
