Solar Generator FAQs: What Home Users Need to Know

The use of solar power systems in homes is becoming more and more popular, but many users have questions about their installation, maintenance and economic benefits. Below are answers to some frequently asked questions to help home users better understand solar power generators:

What factors need to be considered before installation?

• Before deciding whether or not to install a solar PV system, you first need to assess the energy needs of the entire home and the condition of the roof. South-facing roofs are best for installing solar panels, but any unshaded roof in good condition will do.
• Electricity usage and solar power generation need to be confirmed and the required system capacity estimated.

What do I need to be aware of during installation?

• When installing a solar PV system, it is important to ensure that all components comply with the Code of Conduct issued by the State Energy Agency (SEAI) and that the work is carried out by a registered installer.
• After installation, the operating manual, data sheets and warranty information should be read carefully and you should understand exactly how the system works and how to use it correctly for optimum performance.

What are the maintenance and care considerations?

• Solar PV systems are inherently very durable, but they are not zero-maintenance. It’s important to monitor system performance regularly, including routine checks of the inverter to ensure it is functioning properly.
• Although solar panels are robust, it is recommended that they be cleaned every few years, especially in areas by the sea or alongside major roads where more frequent cleaning may be required.

What are the government subsidies and policy support?

• Subsidies from the State Energy Agency (SEAI) are available for systems up to 4 kW peak power.
• From 2022, a Clean Export Guarantee (CEG) has been introduced under the Microgeneration Support Scheme (MSS), which means that owners of solar PV systems can receive a subsidy to compensate them for excess electricity delivered back to the grid.

How do I sell excess electricity back to the grid?

• If your solar PV system generates excess electricity, it can be delivered back to the grid via a smart meter and receive a subsidy for it.
• The installer must submit form NC6 to the ESB network and you will need to have a smart meter installed to take advantage of this benefit.

How are installation costs and financial payback periods calculated?

• The total cost of installing a solar PV system includes the cost of the equipment, the cost of installation and the necessary permits and approvals.
• Careful calculation of the financial payback period is necessary, taking into account the reduction of electricity required from the utility provider and government subsidies.

With these answers, homeowners can gain a more complete understanding of the installation, maintenance and financial benefits of a solar power system. Choosing the right supplier and following the correct operating guidelines are key to ensuring the long-term stable operation of the system.
