CO2 emissions reduced by 22%

Analysis of electricity data shows an impressive reduction in Limerick County Hall's primary energy consumption and CO2 emissions since the installation of its 28.6 kWp solar PV system by Cool Power.

In the first six months of 2009, primary energy consumption in Limerick County Hall was reduced by 132,013 kWh, and CO2 emissions by 26.3 tonnes - a reduction of 22%.

This achievement is a result of the green, clean energy produced by Limerick County Hall's solar PV system (detailed below) together with an associated improvement in County Hall's energy management practices.

Flexible installation

The one solar PV system can have modules in different locations: they don't have to be on the one roof, wall or piece of ground.

The Limerick County Hall solar PV system takes advantage of this feature by siting modules on both the atrium (pictured above and on right, during installation), and restaurant roofs (pictured below).

28.6 kWp of Solar PV

The system on the atrium roof includes ninety-nine 180 Wp Sharp modules and three Fronius IG 60 inverters, providing an output of 17.8 kWp. The system on the restaurant roof includes sixty 180 Wp Sharp modules, providing an output of 10.8 kWp.

This brings the total output of Limerick County Hall's solar PV system to 28.6 kWp.

In terms of emission reductions, the Limerick County Council solar electricity systems (28.6 kWp at County Hall and 10.7 kWp at Limerick Library ) are the equivalent to taking 800 cars off the road for a year.
