SGA – Harnesses the sun’s energy

Posted on: 7th January 2016

On the 11th December Navitron Ltd installed 80 x 250w solar panels on the Hermetics factory roof which equates to 2 x 10kWp systems. The two 10kWp systems should produce an average of 16,540 kWh of electricity per year, this is effectively the energy used by 5 households, it will reduce SGA’s contribution to CO2 emissions (the main greenhouse gas) by around 16000kg’s per annum.

The Photovoltaic (PV) process converts sunlight the most abundant energy source on the planet directly into electricity. The electrical output of photovoltaic modules is dependent on the intensity of the light to which it is exposed. So PV cells will tend to generate more electricity on bright days than when skies are overcast. However photovoltaic cells do not need to be in direct sunlight to work, so even on overcast days the PV cell will generate some electricity to be used in production processes and general supporting activities at SGA.

The average lifetime of a PV module can be in excess of 20 years.


There are many advantages of solar energy which SGA has recognised. Solar energy is a renewable, abundant, sustainable and environmentally renewable energy which supports SGA’s environmental policy of minimising our activities impact on the environment.
