250 Watt PV panels
(Detailed technical specs available on request)
The PV cells (or Photovoltaic solar cells) are the easiest way of harvesting clean energy from the nature. Every day countless KWh’s (kilowattshour) are delivered to us by the Sun, Earth’s largest source of energy. Most of this FREE energy is not used and goes to waste.
In Ireland, the ESB is willing to pay for your surplus energy, if you are willing to poor it into the national grid. During times of no domestic usage, while you are in work during the day, or while you are away from home for weeks during holidays, the PV system will keep generating energy and earn you money.
The photovoltaics will collect and deliver free electricity every day of the year.
There is an average of 12 hours of light a day, between the shorter winter days and the longer summer days. Even on a very cloudy day the PV cells will still generate electricity.
How profitable is a PV cell system?
For the PV’s the maximum power output is calculated during the peak time of sunny spells. In Ireland this peak time it’s estimated at an average of 3.5 hours per day, around the year. For instance a 1 Kw PV cells system, will ensure a production of 3.5Kwh per day, or approx 1, 275 Kwh per year.
If you want calculate how quickly the PV system pays for itself, you can compare the installation costs versus your typical yearly electricity bills. You will see that, made in a D.I.Y. method , the PV system pays for itself in less than 3 years.
Using a contractor, prices usually treble, so the PV system will pay for itself in 10 or more years.
However, due to long and trouble free operation, with PV cells working for at least 30 years, any PV system is highly efficient and profitable, both on medium and long run.
