What Downings homeowners ask about solar
How much do solar panels cost in Downings?
A 4kWp system in Downings typically costs €5,000-€8,000 before grants. After the €1,800 SEAI grant and 0% VAT, the net cost is €3,200-€6,200. The system generates approximately 3,268 kWh/year, paying for itself in 4-6 years.
What roof direction is best for solar panels in Downings?
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.
What is the Microgeneration Support Scheme?
The Microgeneration Support Scheme allows homeowners to sell surplus solar electricity back to the grid at 15-25c/kWh. You need a smart meter (free from ESB Networks) and a grid-connected system. The first €400/year of export income is tax-free.
What is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight. Solar thermal panels heat water directly. For most Irish homes, solar PV is the better investment: it's more versatile, qualifies for the SEAI grant, and you can sell excess electricity. Solar thermal only heats water.
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).
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year, so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
How does shading affect solar panels in Downings?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
