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

Do solar panels increase property value in Newtownmountkennedy?
Yes. Solar panels improve your BER rating and can increase property value by up to 4%. Buyers increasingly look for energy-efficient homes with lower running costs. A solar system in Newtownmountkennedy is a long-term investment in your property.
Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in Ireland. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.
What happens to my solar panels if I move house in Newtownmountkennedy?
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 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 do I get the SEAI grant in Newtownmountkennedy?
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.
Do I need planning permission for solar panels?
Most residential solar installations are exempt from planning permission, provided panels don't project more than 15cm from the roof and don't cover more than 50% of total roof area.
Can you go off-grid with solar in Newtownmountkennedy?
Fully off-grid setups are rare in Newtownmountkennedy. 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.
