A full roof covered with pv solar panels At PV Green Energy Savings (PV Panel installers and equipment suppliers) we are bringing to Ireland for the first time, a renewable energy system that is clean, maintenance free and extremely cost effective. Our system uses photovoltaic (PV) solar panels, which use the energy from the sun to generate electricity for your home or commercial premises.
“But surely that can’t work in Ireland!” PV solar panels generate their electricity from solar radiation, which is emitted to the earth regardless of local weather conditions. All the system needs to generate power is daylight. This makes a system of this kind ideally suited to the Irish climate.
Sounds interesting, how does it work?
The system consists of an array of solar panels which are usually mounted on the roof, or can also be set up in a standalone area to the side or rear of a property depending on the space available on the site. The pv solar modules are made up from panels containing the actual solar cells. The maximum amount of power will be generated when the system faces in a southerly direction.
The panels are linked to the main electricity supply with a connector that automatically switches to solar power when available (during daylight hours) and switches back to the national grid when darkness falls. You now have a choice as to what time of the day to run your Heavy Users so as to get the maximum benefit from the free electricity generated by the solar array.
PV is here already
PV is a clean energy. It does not require the consumption of any fossils fuels. It does not impact the environment in any negative way. It is a long term solution for your property or business and will assist you in dramatically slashing your energy bills.
This method of small scale power generation is known as ‘micro generation’ and is a proven concept worldwide. In fact, you have seen PV solar cells before; you probably did not even notice them.
The application of PV technology is growing at an exponential rate. The next time you travel down any motor way in Ireland, keep a look out for the Emergency ‘SOS’ contact points in the hard shoulder, these units are all powered by small PV panels sitting just above the emergency equipment. Road signs at school crossing points that are time sensitive are now also powered with PV cells.
In the 1990s several governments grasped the possibilities of the practical application of this technology in terms of electricity generation. The adoption of PV technology for the domestic market was championed and Germany, Japan and the US state of California were the front runners in championing PV technology. In these regions, home owners were encouraged via subsidy schemes to install roof mounted PV units. Ireland is now following suit and PV Green Energy Savings can provide renewable photovoltaic systems for the majority of domestic and commercial situations.
Summary
So to summarise, a PV system is generally roof mounted, and generates electricity for your home or business from the suns energy. It’s cost effective, maintenance free, (system has no moving parts) and comes with a read out device to allow monitoring and tracking of generation patterns.

The Basics of Photovoltaic Cells in simple language
By converting light into electricity.
pv cells in a pv modulePhotovoltaic (or PV for short), generates electricity by using daylight on silicon solar cells. The cells are made up into a solar module with in turn go into making the PV Solar Panels.
The electricity that is generated is then converted from a DC current to an AC current so you can use it any electrical application. When the electricity generated by the silicon solar cells is not being used, it can be redirected to your immersion to help heat your hot water.
If the system still has excess power floating around there is an option of selling this back to Electric Ireland and, as there are no moving parts, it is silent and virtually maintenance free.
It produces clean electricity which contributes to a greener planet for future generations while providing you with a generous Savings and possible earnings.
PV is at the forefront of Microgeneration and the possibilities are endless for its applications.
Ireland Gets Cloudy, do PV Cells it work on a Cloudy day?
YES, even on an overcast day a PV installation will still be able to generate power. This is because photololtaic cells not only use direct sunlight, but also diffuse solar radiation which is light that has been scattered by dust and water particles in the atmosphere. Obviously the electricity generated is proportional to the intensity of light energy which falls into the conversion area. However, you can still have an electricity supply on a cloudy day!
The benefits of installing PV panels in your home or commercial premises are clear.

PV inverter for the first time in Ireland at truly realistic prices, home and business owners can enjoy the benefits and cost savings of a realistic renewable energy solution. Using the power of solar radiation, PV technology will generate electricity for your premises via pv panels on your roof.
Photovoltaics is not a new technology. The phenomenon of light to energy conversion was first noticed by a 19 year old French physicist in 1939. However, it wasn’t until 1922, when Albert Einstein won the Nobel Prize for his 1904 paper on the ‘Photoelectric effect’ that the possibilities of this technology were truly realised.
The science bit – Einstein and Photovoltaics
From the Nobel Website
Question: For what did Einstein receive the Nobel Prize?
Answer: Einstein was rewarded for his many contributions to theoretical physics, and especially for his discovery of the law of the photoelectric effect.
Question: What is the photoelectric effect?
Answer: The photoelectric effect is a phenomenon in which electrons are emitted from the surface of matter (usually metals) when light shines upon it. Einstein explained the effect by proposing that light consists of small particles, or quanta, called photons, which carry energy that is proportional to the frequency of light. The electrons in the matter that absorb the energy of the photon get ejected. These findings were published in 1905 in the paper “On a Heuristic Viewpoint Concerning the Production and Transformation of Light”. Einstein’s observations that the photoelectric effect could only be explained if light behaves like a particle, not a wave, was instrumental in establishing the hypothesis that light can behave both like a wave and a particle.
PV is here already
The application of PV technology is growing at an exponential rate. The next time you travel down any motor way in Ireland, keep a look out for the Emergency ‘SOS’ contact points in the hard shoulder, these units are all powered by small PV module/panel sitting just above the emergency equipment. Road signs at school crossing points that are time sensitive are now also powered with PV cells.
The really great thing about PV is that as it only uses sunlight, it will work on a cloudy day too!
You’ve also seen PV cells before on your solar powered calculator in the 1980s!
However, it wasn’t until the 1990s that several governments grasped the possibilities of the practical application of this technology in terms of electricity generation. The adoption of PV technology for the domestic market was championed and home owners were encouraged via subsidy schemes to install roof mounted PV units.
Germany, Japan and the US state of California were the front runners in these schemes and in these regions, PV units in the domestic setting is now the norm as opposed to the exception.
Ireland is now following suit and PV Green Energy Savings can provide renewable photovoltaic systems for the majority of domestic and commercial situations.

closeup of pv cells within a pv panel A standard domestic PV Panel installation will be completde in one day.
The installation of the PV Modules within Panels is comprised of the following steps:
Your fitter will arrive at your property at the pre-arranged and agreed time.
All equipment will be brought into your property and arranged at an appropriate access point to the roof.
The PV Modules will be assembled into panels and mounted on your roof.
Domestic electricity supply is temporarily disconnected for a few minutes while the PV system is wired into the house circuit.
Electricity supply is reconnected and the PV system and all connection points are fully tested.
When your PV system is in place, you will be given a certificate of installation along with a detailed demonstration and operation details.
Enjoy the benefits of your new PV Photovoltaic Installation:)
