Do solar panels work in winter in Clare?
Yes, solar panels generate electricity all year round. While output is lower in winter, Clare still receives usable daylight hours even in December. Annual generation figures (3,552 kWh for a 4kWp system) already account for seasonal variation.
What roof direction is best for solar panels in Ennis?
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 increase property value in Ennis?
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 Ennis 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 size solar system do I need for my home in Ennis?
Most homes in Ennis benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 85% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
How much electricity will solar panels generate in Ennis?
Based on Clare county data, a 4kWp system in Ennis generates approximately 3,552 kWh per year, covering 85% of average household use (4,200 kWh/year). Clare receives around 1,343 sunshine hours annually.
Can you go off-grid with solar in Ennis?
Fully off-grid setups are rare in Ennis. 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.
