Solar Panels – simply put; a no-brainer if your house solely relys on electricity. If you are burning oil or gas as your heat source, Solar PV System will take take slightly longer pay-back time wise. But remember, for every 1kW you send to grid, they give you 24cent (Price from Energia Oct 2023 as an example).
So if you are not using it, you are making money!
Couple of questions to ask yourself when making this investment;
- What’s my pay-back time? Supplier should be able to give this estimated time based on your previous 12months of bills.
- With most panels there is a guarantee of 20 years – so make sure you are no more than 7/8yrs of pay back to get the most benefit.
- Orientation and tilt of panels – Get the most out of your system – In Ireland, the ideal orientation for solar panels is typically south-facing. South-facing panels receive the most sunlight throughout the day, as they are angled toward the sun’s path in the Northern Hemisphere.The tilt angle of solar panels in Ireland is often set at around 30 to 40 degrees from the horizontal. This angle helps balance the need to capture sunlight throughout the year. Panels with a fixed tilt at this angle can generate a good amount of energy year-round
