Why Cronin Solar Cork Recommends Solar PV Over Solar Thermal
At Cronin Solar Cork, we help homeowners, businesses, and farms across Cork make the switch to renewable energy. One of the most common questions we get is:
“Should I install Solar PV or Solar Thermal?”
While both systems use sunlight, the truth is clear — Solar PV is the smarter choice for Irish homes today. Here’s why.
What Solar PV Is and Why It’s Powerful
Solar PV (Photovoltaic) panels generate electricity from sunlight — even on cloudy days — which can power your home, heat your water, charge your EV, or even feed excess power back into the grid.
At Cronin Solar Cork, we design Solar PV systems that:
Reduce electricity bills immediately
Work efficiently in Irish weather
Qualify for SEAI solar grants
Can be paired with batteries for energy independence
Unlike Solar Thermal, Solar PV does more than heat water — it gives you complete control over your home’s energy.
What About Solar Thermal?
Solar Thermal systems are designed only to heat water. While this can reduce your hot water bills, they have several limitations:
Cannot generate electricity
Often require a back-up heating system
Not eligible for new SEAI grants
Less flexible for future energy needs
In short, Solar Thermal might be suitable if your only goal is hot water. But in 2026, homeowners and businesses want more than just hot water — they want energy independence, cost savings, and sustainability.
Why Solar PV Is the Right Choice for Cork Homes
Lower electricity bills: Use your solar electricity first, reducing reliance on the grid.
Hot water included: A diverter can heat water using excess solar power.
Future-ready: Compatible with home batteries, EV chargers, and smart energy systems.
Supported by SEAI: Grants of up to €1,800 make installation more affordable.
At Cronin Solar Cork, we specialise in tailored Solar PV installations that suit your home, business, or farm — maximizing savings and efficiency.
