Rathcormac solar panel questions answered
How much do solar panels cost in Rathcormac?
A 4.4 kWp system in Rathcormac typically costs €8,300–€9,000 before grants. After the €1,800 SEAI grant and 0% VAT, the net cost is €6,500–€7,200. The system generates approximately 3,628 kWh/year, paying for itself in 4-6 years.
How do I get the SEAI grant in Rathcormac?
Apply online at seai.ie with your MPRN and Eircode. Use an SEAI-registered installer. Do not start work before your Letter of Offer. After installation, complete a BER assessment. The grant is paid to your bank within 4-6 weeks.
What size solar system do I need for my home in Rathcormac?
Most homes in Rathcormac benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 86% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
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.
Can I get solar panels on an east or west facing roof in Rathcormac?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
How much electricity will solar panels generate in Rathcormac?
Based on Cork county data, a 4kWp system in Rathcormac generates approximately 3,628 kWh per year, covering 86% of average household use (4,200 kWh/year). Cork receives around 1,380 sunshine hours annually.
What is the Microgeneration Support Scheme?
The Microgeneration Support Scheme allows homeowners to sell surplus solar electricity back to the grid at 15-25c/kWh. You need a smart meter (free from ESB Networks) and a grid-connected system. The first €400/year of export income is tax-free.
Can you go off-grid with solar in Rathcormac?
Fully off-grid setups are rare in Rathcormac. 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.
