Are solar panels worth it in Carlow Town?

What is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight. Solar thermal panels heat water directly. For most Irish homes, solar PV is the better investment: it's more versatile, qualifies for the SEAI grant, and you can sell excess electricity. Solar thermal only heats water.
What size solar system do I need for my home in Carlow Town?
Most homes in Carlow Town benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 87% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
Do solar panels work in winter in Carlow?
Yes, solar panels generate electricity all year round. While output is lower in winter, Carlow still receives usable daylight hours even in December. Annual generation figures (3,644 kWh for a 4kWp system) already account for seasonal variation.
What is a BER assessment and do I need one?
A Building Energy Rating (BER) assessment is required after installing solar panels to claim the SEAI grant. A BER assessor visits your home and rates its energy efficiency from A1 to G. Solar panels typically improve your BER by 1-2 grades. The assessment costs around €150-€200.
What happens to my solar panels if I move house in Carlow Town?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. The SEAI grant does not need to be repaid if you sell. Your installer can transfer monitoring accounts to the new owner.
Can you go off-grid with solar in Carlow Town?
Fully off-grid setups are rare in Carlow Town. Most homes stay grid-connected and sell surplus back through the Microgeneration Support Scheme. A hybrid inverter with 10-20 kWh of battery storage covers evenings and power cuts, which is what most people searching "off-grid" actually want. A true off-grid system needs a much larger array and battery bank, and you lose the grant-supported export income.
