Solar PV Panels rethinking energy

Generate your own FREE green daylight electricity and save money with one of Gilroys.ie solar system.

A Solar Photovoltaic (PV) Panel is made up of silicon cells, prepared in such a way that when the sun’s rays pass over them they become ‘agitated’ creating an electric charge. This electricity is generated in the form of direct current (DC) generally the electricity is then converted to alternative current (AC) via an inverter to make it compatible with the electricity supply. Alternatively it can be stored as DC in a battery for use later.

Factors that will impact how much energy a Solar PV system will generate are:

  • The efficiency of the panel.
  • The overall size of the PV array.
  • The latitude of the location.
  • Which direction the panels face.
  • The angle at which the panels are mounted.
  • The amount of shade that may cover the panels.

The Case for Solar PV

Contrary to popular belief, a Photovoltaic system does not necessarily need bright sunlight to operate successfully. A correctly engineered system will continue to generate electricity even on cloudy days.

The first practical application of solar photovoltaic’s was to power orbiting satellites and other spacecraft, but today solar photovoltaic systems are becoming far more main-stream and can be used for any number of exciting applications. While traditionally most systems were grid-connected whereby excess electricity was fed onto the national grid, off-grid or hybrid systems are becoming more popular.

There are many reasons for this on the most basic level off-grid battery storage systems allow communities where there is no grid to have access to electricity. There has also been a trend in the developed world towards on-site storage. Electricity prices are increasing to such an extent that in many cases electricity generated by PV panels and stored on site is cheaper than the electricity that you can buy from the grid.

Many of the grids are in need of upgrading and therefore unable to deal with demand, as a result, we are facing the real threat of grid black-outs in the not too distant future.

“Rang Martin for a quote on a solar pv system with battery, called to our house the next day for a site survey. Martin had the best price of 3 quotations and offered more in the package with a Solar iBoost. Also the products he is using is of a much better quality than the other quotations. I can’t recommend Gilroys Green Energy high enough, any time I rang Martin with a query he answered and was more than happy to explain things to me. When we set a date for the work to commence Martin and his team arrived on time and finished the job quicker than quoted. Thanks Martin, look forward to dealing with you in the future.”
