GRIAN52 offers the highest quality products. See the chart below for a comparison of our solar panels to other models popular in Ireland. We recommend Luxen’s Series 5 panels because of their high capacity and efficiency in comparison with most options available in Ireland, which are typically 250-350W and 16-18% efficient. One needs only 7 panels to meet the maximum capacity paid for by the SEAI’s Solar PV grant of 4kW – less than half the total needed in the case of 250W modules.

*Luxen Series 5 panels are available in 480-500W to 575-595W capacities. Lower capacity panels are available in Series 3 and 4, and a 650-670W panel in Series 6. Efficiencies vary based on watt power.

In addition to our highest quality PV solar panels, GRIAN52 is also proud to begin selling hybrid PV/T modules this year. These modules provide both electric and thermal power by running water behind the solar panels. We recommend the 450W model, which has an electrical efficiency of 20.7% and a thermal efficiency of 58.2%. PV panels lose a great deal of potential energy to heat – typically 80% or more; the addition of water cools the panels and captures thermal energy. Our PV/T panels are able to utilize about as much of the sun’s energy, just under 80%, as most PV panels lose. One can create a renewable CHP system with PV/T as the sole energy source.
In addition to quality products, GRIAN52 also offers expertise in energy efficient and energy system design. We are here to streamline the renewable energy system installation process by tendering for projects and coordinating with a trusted list of contractors, and offer consulting services in design and project management as requested. All a contractor working with GRIAN52 needs to worry about is the installation and vertification of equipment. We can design a solar energy system for any home or business from just a picture of the roof and its dimensions. We offer a 20% commission on all sales, and a gift with the first order of GRIAN52 products. We will also advertise the services of trusted contractors on this website.
GRIAN52 offers customers a one-stop shop for renewable energy. We will design the optimal system to meet your energy needs, and coordinate with a trusted contractor to ensure that installation is completed in a timely and correct manner.
Alongside GRIAN52’s line of high quality, efficient and renewable energy products we also offer a number of unique products designed to decrease water waste. We offer a bio septic tank and water purification system which produces fertiliser and clean water from sewage, a rainwater harvesting system which can also be used with a purification system to produce clean water, and a environmentally friendly alternative to concrete for foundations — a paving system for use with grass or gravel. The rainwater harvesting system and grass paving grid can also be used separately or in tandem to prevent mud, flooding, and erosion.
When ordering from GRIAN52, there is no need to go to a bank to apply for a loan. GRIAN52 is partnered with Humm to offer financing up to €30,000. Applications take only 2 minutes and one needs only a PPSN and salary information to apply. We will also help our customers to secure any funding for which they are eligible through the SEAI, including Solar PV and Thermal grants.
