As the Summer Solstice hit us on June 21st, Ireland experienced its longest day of the year, with up to 16.5 hours of daylight. This period is a golden opportunity for solar energy enthusiasts and newcomers to maximise their solar power generation.

The extended daylight hours and clearer skies mean solar panels can produce more electricity. This significantly reduces energy bills and contributes to a greener environment.

This abundance of sunlight means your solar panels can generate more electricity on this day compared to other days of the year. For instance, in Ireland you can expect around 30-40% more solar energy production in the Summer Solstice. This is compared to an average day in December.

Whether you’re a seasoned solar power user or a newcomer, this guide will help you optimise your home solar setup. You’ll harness the sun’s power just in time for the sunshine surplus.


The Solar Surge: Energy and Savings in the Summer.

The Summer Solstice marks the longest day of the year, with up to 16 hours of daylight in Ireland. This extended period of sunlight allows solar panels to generate more electricity than on other days.

This energy is enough to power a million homes for the day or make hundreds of millions of cups of tea. This remarkable output highlights the potential savings and energy generation that can be achieved during this peak period.

On days like this solar panels can generate up to 30% more energy than the winter solstice, when the sun is at its lowest point in the sky and daylight hours are shorter. Solar energy can significantly reduce energy bills. Savings for homeowners can be even higher during the Summer Solstice due to increased energy production. On a well-optimised system such as we supply our customers at Solarstream, the savings in the Summer can be significant, potentially reducing your energy costs to nearly zero for this period.

With its long daylight hours and abundant sunshine, the summer solstice presents an opportune time for Irish homeowners to install solar panels. With €500 off a new system or 2 free panels the savings are not just for Summer but for long term too..
