Frequently Asked Questions

Yes. Homeowners in Ireland can avail of grants through the SEAI (Sustainable Energy Authority of Ireland). These grants can significantly reduce the upfront cost of installing solar PV systems, depending on the system size and eligibility.
The SEAI currently offers grants of up to several thousand euro for residential solar PV installations. The exact amount depends on the size of your system. We guide you through the application process to ensure you receive the maximum available support.
The cost of a solar PV system varies depending on system size, property type, and whether battery storage is included. Most residential systems in Ireland range from €5,000 to €12,000 after grants. We provide a tailored quote based on your energy needs and property.
Most customers see a return on their solar investment within 5 to 7 years, depending on energy usage, system size, and electricity prices. With rising energy costs, many systems can pay for themselves even sooner.
Absolutely. Solar panels generate electricity from daylight—not just direct sunlight—so they work efficiently even on cloudy days. Ireland’s climate is well-suited to solar PV, and systems are designed to perform year-round.
Yes. Battery storage systems allow you to store excess energy generated during the day and use it later, such as in the evening or during peak times. This increases your energy independence and savings.
Savings vary, but many homeowners reduce their electricity bills by 30% to 60% or more, depending on system size and energy usage habits.
