Solar Panel FAQs for Rostellan
How much do solar panels cost in Rostellan?

Do I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid. ESB Networks installs smart meters for free. Your installer submits the NC6 form to ESB Networks after installation, which triggers the meter upgrade if needed.
What is the payback period for solar panels in Rostellan?
With a net cost of €6,500–€7,200 after the SEAI grant and savings of €1088+ per year plus export income, a typical solar system in Rostellan pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
How much electricity will solar panels generate in Rostellan?
Based on Cork county data, a 4kWp system in Rostellan 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 happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect ESB workers). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
What happens to my solar panels if I move house in Rostellan?
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.
How long does solar panel installation take?
A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the ESB Networks notification (NC6 form).
Can you go off-grid with solar in Rostellan?
Fully off-grid setups are rare in Rostellan. 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.
