Is there really enough sunlight in Ireland for solar to be effective?
Yes. Ireland gets just over half the solar energy received at the equator - more than enough to operate a solar water heating system. Over the year, a typical solar water heating system in Ireland provides 50% to 70% of annual domestic hot water requirements (approximately 90% in summer, 50% in spring, and 20% in winter). A solar energy system provides heat input even on cloudy days by using energy from diffused light.
Even in winter, the system will pre-heat the water in your cylinder, which will make a significant reduction to your gas, oil or electricity consumption throughout the year.
How do I get hot water even when it isn't sunny?
The solar water heating system works alongside your existing hot water system. On cloudy days, even a little sunlight will pre-heat the water in your cylinder, and your boiler or immersion heater will do the rest.
How big is the solar panel / collector?
This depends on the optimal size of system for your property, the number of people in the house, the capacity of cylinder installed, and the available roof area. Generally a two person household will require 3m2 of panel area and a three to four person household would require 6m2 of panel area. We can advise on the best sizing for your property during the free site survey.
What will need to be done?
If the solar panels are to be installed on the roof, scaffolding must be erected to comply with Health & Safety requirements. Securing the solar panel involves removing and replacing half a dozen roof tiles. The installers will also need access to the loft space. Your existing cylinder will need to be replaced by a dual coil cylinder, and the solar panel will be connected to the dual coil cylinder with new pipe work.
How long will it take to fit the system?
A Solas Solar Water Heating System can be fitted in about two days. Our installation teams will take care to clean up after themselves and you will not be without hot water for more than a few hours.
