Solar PV.

Energywise are one of Munster’s leading installers of solar PV panels also know as solar photovoltaics. Our solar PV systems are installed in 1 day complete with a 10 year warranty for peace of mind. Energywise Ireland have partnered with Solitek, a European manufacturer of solar PV panels with 22 years of experience. Solitek manufacturer their panels in Europe with Scandinavia being their biggest market. The panels are manufactured using renewable energy without any CO2 emissions and the organisation are in the process of attaining C2C certification which will certify the product as totally sustainable. Production is powered and cooled by renewable energy mix – both solar (150 kW on the roof of the building) and geothermal (108 boreholes as deep as 148 m underground), which produces 1 MW of Geothermal power.

The modules are some of the finest crafted solar PV panels on the market but have also been tested for years in the harshest of conditions in Norway, Sweden and Finland in extreme temperatures and near coastal areas. We believe this is very important for Ireland with it’s harsh Atlantic climate. The Solid Pro frameless glass panel is almost indestructible and with salt resistance, is ideally suited for long life and against the harsh weather the Atlantic Ocean will throw at them. The power output is also extremely high at 320W per panel and depending on your household usage, it is possible along with battery storage to power up to 80% of your home electricity requirements with solar PV.

How do solar PV panels work?

Sunlight is made up of photons, and when it hits the semi-conductor metal of the PV panel, electrons are released; these electrons form a direct current. People have been using PV for years, for example Sharp release their first pocket calculator in 1976 which has a number of PV cells. A typical solar PV systems consist of three main elements:

The inverter is an electronic device that converts the DC electricity produced by the solar array into AC with the same voltage and frequency as the mains supply. The inverter also performs various safety functions, constantly monitoring the grid and switching off in the event of a fault or major fluctuation in mains supply. The output of the inverter goes directly into the building’s fuse box – feeding solar electricity into the building’s conventional electricity supply which means you will not have to buy so much electricity from your electricity supplier.

The appliances in the building will use the free electricity generated from your solar PV system and any surplus power will automatically be exported into the grid so that others can buy the “green” electricity you have generated Most solar PV systems are grid connected, which means that the electricity generated is fed directly into (and synchronised with) a building’s existing mains supply. On a sunny day, the power generated by the solar PV system reduces the amount of electricity that needs to be bought from the electricity supply company. On very sunny days, or at times when not many loads are turned on, the PV may generate more power than is needed in the building, and the surplus will be exported out into the grid. There are six main factors that will impact how much energy a Solar PV system will generate:

SoliTek panels are Cradle to Cradle Certified® To receive certification, products are assessed for environmental and social performance across five critical sustainability categories: 

Cradle-to-cradle

Material Health – The material health category helps to ensure products are made using chemicals that are as safe as possible for humans and the environment by leading designers and product developers through a process of inventorying, assessing and optimizing material chemistries. As a step towards full certification, manufacturers may also earn a separate Material Health Certificate for products that meet Cradle to Cradle Certified™ material health requirements.

Material Reutilization – The material reutilization category aims to eliminate the concept of waste by helping to ensure products remain in perpetual cycles of use and reuse from one product use cycle to the next.

Renewable Energy & Carbon Management – The renewable energy & carbon management category helps to ensure products are manufactured using renewable energy so that the impact of climate changing greenhouse gases due to the manufacturing of the product is reduced or eliminated.

Water Stewardship – The water stewardship category helps ensure water is recognized as a valuable resource, watersheds are protected, and clean water is available to people and all other organisms.

Social Fairness – The aim of this category is to design business operations that honour all people and natural systems affected by the manufacture of a product.

Does Solar PV work in Ireland?

There is an opinion out there that Solar technology would not work in Ireland , this stems from people thinking that we don’t get enough sunlight in the summer, never mind the winter. This however is not true, photovoltaic cells work on sunlight as opposed to the heat from the sun. In fact, Ireland has the same annual Irradiation levels as many parts of central europe, ranging from 1200 kWhr/m2/yr in the south of the country to 1000 kWhr/m2/yr in the north of the country, a good average for the entire country is 1100 kWhr/m2/yr. If you consider our typical winters would not be as bad as many parts of central europe, our mild climate is ideal for solar installations, as we never get too hot or too cold and we have good light levels for a large part of the year.

FAQ's

Solar PV panels produce electricity by converting sunlight into electricity. The amount of electricity that is produced is dependent on how sunny it is and how many solar panels are grouped together. Solar PV systems sizes are rated based on their maximum potential output under full sunny conditions and is rated in kilowatt peak (kWp). A 1 kWp solar PV system would produce about 800 units of electricity per year in Ireland.
When your heat pump needs most electricity, your PV panels are producing the least amount of electricity i.e. short winter days. The PV panels will contribute to your annual electricity demand but can’t be relied upon for instantaneous demands.

Solar panels, whether for hot water or for electricity, should be orientated in a Southerly direction between South East to South West. So if the back of the house faces towards the South, then this is the correct location. 

For solar PV Panels it is generally not a problem to install the panels on the garage provided that the orientation is correct.

Testimonials

For a few years we have been considering the addition of a PV solar system on the roof of our home in County Kerry. We spent many hours researching available systems, ESB tariffs, size options, costs and all other aspects. We spoke to a handful of good companies about the subject. In the end we made the decision to give EnergyWise Ireland the go ahead to install a system. They laid out the complete project proposal for us to consider. They paid particular attention to our concerns about the effect high wind might have on the solar panels; our home is situated near a tidal bay subject to high winds in the winter. They outlined their reasoning for recommending the solar panels and the inverter manufactures; all the warranties and advantages. They oversaw all the official documentation needs, and they advised us on the process with ESB. On the two days of the instillation they were clean and professional. In fact the wiring from the PV panels to the fuse panel and Inverter is the tidiest wiring in our home. Our system today cranks out power trouble free. In installing this system we have effectively slashed our electricity cost permanently. We look forward to twenty five plus years of greatly reduced ESB bills. I recommend EnergyWise Ireland even if you are just considering the option of PV solar panels on your home our business. They have the experience, expertise and resource to provide a professional first class service and an excellent finished job.
