How do I get the SEAI grant in Grangecon?
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 happens to my solar panels if I move house in Grangecon?
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.
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 roof direction is best for solar panels in Grangecon?
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.
Do solar panels work in winter in Wicklow?
Yes, solar panels generate electricity all year round. While output is lower in winter, Wicklow still receives usable daylight hours even in December. Annual generation figures (3,788 kWh for a 4kWp system) already account for seasonal variation.
How much electricity will solar panels generate in Grangecon?
Based on Wicklow county data, a 4kWp system in Grangecon generates approximately 3,788 kWh per year, covering 90% of average household use (4,200 kWh/year). Wicklow receives around 1,448 sunshine hours annually.
Can you go off-grid with solar in Grangecon?
Fully off-grid setups are rare in Grangecon. 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.
