Do solar panels increase property value in Keenagh?
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 Keenagh is a long-term investment in your property.
Do solar panels work in winter in Longford?
Yes, solar panels generate electricity all year round. While output is lower in winter, Longford still receives usable daylight hours even in December. Annual generation figures (3,416 kWh for a 4kWp system) already account for seasonal variation.
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).
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.
What is the payback period for solar panels in Keenagh?
With a net cost of €6,500–€7,200 after the SEAI grant and savings of €1025+ per year plus export income, a typical solar system in Keenagh pays for itself in 4-6 years. After payback, you get 20+ years of near-free electricity.
Is my roof suitable for solar panels in Keenagh?
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.
Can you go off-grid with solar in Keenagh?
Fully off-grid setups are rare in Keenagh. 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.
