Generate Your Own Free Electricity

Our solar photovoltaic range of products offer our customers an environmentally friendly means of producing your own electricity. This provides long term energy savings, reduces carbon emissions and makes us less dependent on imported energy. See your property’s energy rating climb with the introduction of solar photovoltaic.

Passive House Systems are specialist suppliers of solar PV products. We are the first company in Ireland to get NSAI Agrément Certification for solar PV systems. With years of experience in the industry and with our own dedicated solar engineering department, we understand how to design for cost effectiveness, building compliance and quality assurance, giving our customers 100% peace of mind.

Why Solar PV?

Solar PV offers the most convenient and simple solution to turn your building into a renewable energy generator. As the efficiency of the solar PV technology improves and the price continues to fall investing in a solar PV system has become an excellent initiative, offering significant savings into the future and providing a protection from rising energy costs.
Our systems are designed for both domestic and commercial applications. Solar PV technology is a very established means of generating renewable energy worldwide. We only offer the highest quality solar PV components and accessories, direct from reputable manufacturers.

Part L Compliance

All new buildings must meet a minimum provision of installed renewable energies. Solar PV is ideal for this:
• 4kWh/m2/annum of renewable electrical energy.
• 10kWh/m2/annum renewable heat contributing to energy use for domestic hot water heating.
• A combination of these that would have the equivalent effect.

Solar PV System

Solar Photovoltaic systems offer the ideal renewable energy generations system. The system has no moving parts, little to no maintenance and a limitednumber of easy to install components. Solar PV also has a long working life providing free and clean electricity from the sun for over 25 years.
The panels are producing DC voltage during daylight hours. It’s converted immediately to normal ESB compatible voltage and distributed throughout your property. It is possible to export the excess power back to the grid, or use it for space or water heating. The sun provides us with an unlimited and reliable source of free energy. Solar PV panels harness this free and natural energy and convert it into useful electricity.
Just imagine that you could get all your electricity from the panels during periods of the day. All our PV are tested to the highest quality in NSAI & TUV audited factories and come with a 25-year production warranty as standard.
Certifications:nsai certification
  • EN 61215,
  • CE Certified (EN 61730),
  • MCS 010-1.5, MCS 005-2.3,
  • EN ISO 9001 & 14001.

*See NSAI Certificate 18/0395 for a full range of panel types and properties.

String Inverters

The Inverter is required to convert the DC current generated by the PV panels into an AC electric current, this can be used by the appliances in your home or exported into the grid. Passive House Systems offer a range of inverters to suit your needs. All our inverters come with a five year warranty which can be extended to ten years. 

The range has exceptionally low input voltage making them suitable for very small systems of just two modules. All products offered are certified to EN50438 for the Irish market.  We offer inverters in single phase (for domestic dwellings) and three phase (for industrial applications). All our inverters are certified to EN50438, to comply with Irish grid requirements:

  • Over 95% max efficiency,
  • 50V – 400V operating voltage,
  • Protection Class IP65 rating,
  • Precise MPPT system,
  • Optional Wi-Fi and App monitoring,
  • 5 year warranty extendable to 10 years.


  • Grid regulation EN50438 Irish Deviations,
  • CE Certified to EN62109-2:2011 & EN62109-1:2010,
  • Safety IEC62109-1 & -2,
  • AS3100, EMC: EN61000 (6-1, 6-2, 6-3, 6-4, 3-2, 3-3),
  • EN ISO 9001 & 14001.

Micro Inverters

Our micro-inverters mark a breakthrough in solar technology, making PV arrays more powerful, smart, bankable, cost effective and safer. Conventional string inverters operate as efficiently as the lowest-performing module, meaning reduced output from a shadow or leaf on one module cuts output across all modules in the array. Passive House Systems micro-inverters are smarter.

Our technology individually monitors and maximizes power generation for each module in the array, boosting system efficiency by up to 20 percent. One unit handles two PV modules, lowering installation and system costs. All micro-inverters are engineered to comply with local grid requirements, ensuring safety of system installers and emergency responders.

PV Mounting System

Schletter PV mounting systems are a high quality range of fixing products, manufactured in Germany and offer a wide range of components and systems to facilitate the fastening of almost any module configuration, to almost any roof. Usually, two horizontal mounting rails carry one row of PV modules mounted vertically. These rails are fastened to the roof structure using roof hooks or other fasteners. The modules are fastened to the rails using middle and end clamps. Accessories are available for most applications.An MCS012 certified, Schletter Rapid2+ mounting system provides quick and simple installation.

  • Trapezoidal Clamps,
  • Standing Seam Clamps,
  • Rapid 2+ Tile Hook,
  • Flat roof/Ground mount,
  • Rapid 2+ slate flash kit,
  • Hanger bolts.


Roof and Felt Grommets

The multi-cable Solar Flashing EPDM Roof Grommet is a speciality flashing for managing solar PV cables on tile or slate roofs. It allows up to 10 cables to be taken effectivelythrough any roof. It also helps to avoid risk of damage, by isolating them and provides a complete weatherproof seal.

Felt Grommets ensure there is no compromising of your roof felt integrity, by routing your cabling through. Fully adhesive, with a flexible EPDM rubber to reliably facilitate cables penetrating the roof felt.

Battery Storage

Lithium-iron phosphate battery technology is one of the most reliable, safe and long-lasting lithium battery technologies currently available due to its uniquely high chemical stability and resulting extremely high application reliability, durability and lone life. 

Connecting photovoltaic systems to a battery system can enhance consumption of your self-generated electricity. We can design and supply a hybrid inverter and battery storage combined system which allows greater utilisation of your solar installation. We offer a range of battery types and sizes to suit different budget and system sizing.



Power Diverter

The solar diverter uses the surplus photovoltaic energy generated at your home to heat the water in your standard cylinder and save you money.

You will benefit from:

  • Maximising the use of the free solar energy generated at your property,
  • Cutting the cost of heating your water,
  • Reduced use of your boiler.

The solar diverter uses ONLY energy which would be otherwise exported, so you take the opportunity to use as much of the free solar energy as possible.

PV Optimisers

Solar PV optimisers increase energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually.

The MPPT per module allows for flexible installation design with multiple orientations, tilts and module types in the same string. This allows the installer even greater flexibility with longer strings and strings of different lengths in order to design optimal PV systems.
