What Tallow homeowners ask about solar
How much do solar panels cost in Tallow?

What roof direction is best for solar panels in Tallow?
South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in Ireland.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year, so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
What size solar system do I need for my home in Tallow?
Most homes in Tallow benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 79% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
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.
Are solar panels worth it in Tallow?
Yes. With estimated savings of €996+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Tallow pays for itself in 4-6 years and lasts 25+ years.
Is my roof suitable for solar panels in Tallow?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.
