Mayo homes urged to cash in on solar as survey reveals myths and missed opportunities

A new survey has found that many Mayo homeowners are still in the dark when it comes to how solar power really works, despite record levels of solar energy now being fed into the national grid.

Research by Bord Gáis Energy shows that over one in three people (34%) incorrectly believe that solar panels only generate electricity when the sun is shining.

In reality, modern solar panels continue to work efficiently on cloudy or rainy days, meaning homes from Belmullet to Ballyhaunis could be cutting bills and even earning money from their rooftops year-round.

Last month alone, solar power accounted for more than 6.5% of Ireland’s total electricity, generating 173,163 megawatt-hours – more than double the same time last year.

Despite the growing contribution of solar, just 17% of people plan to install panels in the next year. While over half (56%) are aware that solar can actually make them money, many remain hesitant.

Here’s how it works: a home with panels that exports 8 kWh per day at Bord Gáis Energy’s current rate of €0.185 per kWh could earn €1.48 daily – more than €10 in a sunny week. With 370,000 homes already fitted with panels, the combined income potential is estimated at over €4 million a week.

Valerie Hand, Retrofit Manager with Bord Gáis Energy, said there is still a big knowledge gap. “Many don’t realise that solar works brilliantly in Irish weather – and that their roof could not only be saving them money but also earning them money. We want to help people on their Net Zero journey and believe solar will play an integral role in achieving a greener, fairer future while supporting the government’s Climate Action Plan targets.”

Affordability remains a sticking point. Over half (53%) of people said better grants would encourage them to invest, while 51% want more clarity on long-term savings. Government supports of up to €1,800 are currently available, and Bord Gáis Energy is offering free consultations to help households understand potential savings and eligibility for grants.

Typical installation costs are in the region of €8,000 to €10,000, with finance options now available through Finance Ireland. Systems are built to last for more than 25 years and can reduce electricity bills by up to 70%.

The study also revealed that “keeping up with the Joneses” has an influence on decision-making: almost half (46%) said seeing neighbours install panels would positively affect their own choice.
