The Best Way to Produce Electricity

When people think about electricity generation in Ireland, they often imagine wind farms, gas plants, or traditional rooftop solar panels tilted toward the sun. However, one of the smartest and most efficient solutions for Ireland’s climate is often overlooked: vertical solar panels, especially bifacial vertical solar panels.

Vertical solar panels are mounted upright rather than angled on a roof. These produce energy from direct sunlight from above, and bifacial modules also capture light on both sides — front and back — using direct and reflected sunlight from the ground, nearby surfaces, and the naturally bright Irish sky. This makes them particularly effective in Ireland, where cloud cover is common and sunlight can often be diffuse in nature, rather than direct. Additionally, due to changing weather patterns, where there is cloud in the morning it can often be sunny in the afternoon – bifacial solar panels in a vertical configuration will certainly produce energy under such daily conditions – whereas a roof-mounted system may have missed the opportunity to produce.

Ireland’s weather actually makes vertical solar more attractive than most people realise. Traditional roof-mounted solar works well in strong, direct sunshine, but Ireland experiences frequent overcast conditions and low winter sun angles. Vertical panels perform better during these darker conditions because they can capture morning and evening sunlight more effectively and continue generating when the sun sits low on the horizon. Studies on Irish solar output show that even in winter, solar can still provide meaningful energy generation, with modern systems benefiting from moderate temperatures and diffuse sunlight conditions. Bifacial panels can also add up to 30% more energy by collecting reflected light from both sides throughout the day.

Another major advantage is cost. Vertical systems reduce maintenance and cleaning costs because rain naturally washes the panels, and dirt, dust, and leaves are less likely to settle on a vertical surface. Snow and frost are also less of a problem compared to tilted panels, helping systems stay productive in poor weather. Reduced cleaning and lower performance losses from dirt — known as soiling — improve long-term return on investment.

Vertical panels are also excellent in relation to land use. Instead of taking up valuable roof or field space, they can be installed as boundary fences, along roads, around farms, beside warehouses, or integrated into commercial buildings. This means electricity can be generated without sacrificing agricultural land or development space. For Ireland, where land value and planning restrictions can be significant barriers, this is a major benefit.

Perhaps the biggest financial advantage is the production pattern. Traditional south-facing solar panels produce most of their electricity around midday, when demand is often lower. A lot of this energy will eventually end up being dumped, discarded due to the exorbitant costs of grid-scale batteries and storage. Vertical east-west bifacial panels create two production peaks — one in the morning and one in the late afternoon — when homes and businesses actually need power most. This improves self-consumption, reduces grid stress, and makes the electricity more valuable. Research has shown vertical bifacial systems can outperform traditional monofacial systems in winter and provide stronger all-day generation patterns in every season.

Vertical Solar panels can produce energy as and when the grid requires it.

In Ireland, the best electricity solution is not simply the cheapest panel — it is the system that works best with the climate, land, and energy demand. Vertical bifacial solar panels offer lower maintenance, better winter performance, improved efficiency, smarter land use, and stronger long-term savings. Most importantly, they also produce more electricity per kWp installed, up to 30% more, and that’s critically important for financial returns, lowering the LCOE, and thereby reducing overall energy costs for homes & business alike.

For Irish homes, farms, and businesses looking for reliable and affordable power, vertical solar is not just an alternative — it is the future of electricity generation.
