SolarWorld

World Class Design & Technology

SolarWorld photovoltaic systems allow you to use solar power at home to reduce your electricity costs by providing a large portion of your electricity needs. SolarWorld boasts over 35 years of expertise in crystalline solar power technology and its solar modules are subject to German quality standards, comprehensive quality assurance and extensive product tests.

Comprehensive Quality Tests

Intensive tests that greatly exceed international standards ensure that only premium quality products leave the SolarWorld factories.

  • Weather resistance tests mimic temperature shock, humidity-freeze, damp-heat conditions
  • Hot spot tests identify any micro flaws which may damage the module over the long term
  • Electrical Insulation to ensure proper insulation in both wet & dry conditions
  • Mechanical load tests performance when exposed to high winds, wind suction and snow loads
  • UV light aging tests - extreme levels of UV radiation simulates 25 years of radiation to ensure durability
  • Module breakage and hail impact tests
  • Salt spray resistance
  • Incoming goods inspection to ensure only the highest quality raw materials

SolarWorld 25 year Linear Performance Guarantee

SolarWorld guarantees the performance of your PV system over 25 years providing confidence in the long term performance of an investment in Solar Photovoltaic.

  • Guaranteed maximum performance reduction of 0.7% per year
  • Guaranteed performance of 90% after 11 years
  • Guaranteed performance of 80.2% after 25 years

Power generation from solar PV has been used for over fifty years and is a clean sustainable energy technology. The direct conversion of sunlight to electricity occurs without any moving parts or environmental emissions during operation, as a result PV systems have low maintenance and operating costs.

Designing your Solar PV system

SolarWorld systems are innovative on roof or in roof solutions suitable for either slate or tile roofs with an incline of between 15o and 60oC. Heat Merchants and SolarWorld will provide a detailed PV system design and will custom assemble a kit to fit your specific needs.

As this is a bespoke service we have the right solution for every roof taking into consideration the end users individual requirements as well as the specific building and

on-site conditions. This facilitates a quick and easy installation by a RECI approved electrician on site using the provided mechanical and electrical plan.

Solar Photovaltaic Frequently Asked Questions

Q: What are solar modules? The sun supplies us with energy in the form of electromagnetic radiation on a daily basis. This radiation can be exploited with the help of the photovoltaic effect. To do so, the semi-conductor material silicon can be used. When the thin silicon discs known as wafers are exposed to radiation, electrons are set free and can be used to create electricity. To increase a wafer’s yield, a special coating is applied which gives solar cells their distinctive blue or black colouring. A thin lattice consisting of metallic conductive strips is also affixed to ensure that the current can be conducted and used. Once this production stage is completed, wafers then become solar cells. The solar cells are arranged in rows and interconnected in so-called strings. Several strings are placed next to one another to form a photovoltaic module, which is then laminated in the last production stage to make it airtight and waterproof. The module is now ready to convert sunlight into electrical energy.

Q: Where should I install the solar panels? As a general rule, solar power systems can be installed in any location where there is sufficient light. A southfacing surface achieves optimum yield at an angle of about 30o A variation in orientation towards the southwest or south-east or in pitch between 25o and 60o will only reduce the energy yield slightly. Shade produced by trees, adjacent buildings, gables, aerials and similar should be avoided, as they considerably reduce the electricity yield.

Q: What happens to the electricity produced by the PV System? The electricity is consumed in the dwelling by your appliances that are working at the same time as your PV System. The power from the PV system is used firstly & topped up where required by the standard supply line.

Q: Can I make use of the excess electricity used? No. Currently in Ireland you can’t export back on to the grid for any form of pay back. There is no feed in tariff in existence at the moment.

Q:Is it a renewable energy source for compliance with building regulations Part L? Yes! It is a full renewable energy source and can contribute as part of your compliance to your Part L within your building regulations.

Q: Is the PV System safe? Yes! Once it is installed by a Registered & competent installer and all guidelines are followed it is as safe as any other appliance in your home. As with all electrical appliances due care and attention must be given at all times.

Sunfix On Roof Solar PV System

Sunfix is a versatile support structure for installation of solar modules on pitched roofs. Each system is individually preassembled as a complete set, based on the existing roof structure and provides for multiple mounting options, with either vertical or horizontal module alignment. The light aluminium frame ensures low roof load and allows for fast and easy installation without causing any damage to the existing roof. Tile and slate roof versions available.

Sundeck In Roof Solar PV System

Fast and straightforward installation is a key feature of this system - it is fastened directly onto the substructure of the roof, at the same level as the rest of the roof and it has few parts ensuring installation couldn’t be easier. A galvanized steel plate with an additional polyester coating delivers lasting corrosion resistance. There are versions of the Sundeck developed for both tile and slate roofs.
