What size solar system do I need for my home in Castleplunket?
Most homes in Castleplunket benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 83% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
Do solar panels work in winter in Roscommon?
Yes, solar panels generate electricity all year round. While output is lower in winter, Roscommon still receives usable daylight hours even in December. Annual generation figures (3,468 kWh for a 4kWp system) already account for seasonal variation.
Is my roof suitable for solar panels in Castleplunket?
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.
Do solar panels increase property value in Castleplunket?
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 Castleplunket is a long-term investment in your property.
How do I get the SEAI grant in Castleplunket?
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 Castleplunket?
Fully off-grid setups are rare in Castleplunket. 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.
