Solar Panels: A Guide to Costs and Benefits

Are you considering solar panels for your home? Learn about different technology options, installation costs and grants available.

Considering the rising electricity costs and the increasing interest in sustainable living, many homeowners are exploring the benefits of solar panels for their homes. In this article, we'll delve into the world of residential solar panels, exploring technology options, efficiency, installation, costs, and available grants in Ireland.

Solar Technology Options for Homeowners

When it comes to solar technology, homeowners can choose between photovoltaic panels (PV) and thermodynamic panels. Photovoltaic panels generate electricity for powering homes, including heating water, while thermodynamic panels focus solely on heating water.

How much electricity can solar panels generate?

Solar panels, with the right system, can provide homeowners with all the energy they need, and even a surplus that can be sold back to the grid. Even on cloudy days, solar panels generate electricity, albeit not at their maximum capacity. Location and a battery storage system are crucial considerations for optimal efficiency.

Designing a Rooftop Solar PV System:

When opting for a rooftop solar PV system, considerations include system size, the inclusion of battery storage, and additional features like a hot water diverter or an EV charger. High-capacity panels from top global brands are recommended for limited roof or garden spaces, maximising the available area.

Installation Process and Timelines:

The installation timeline for PV solar panels varies based on factors such as system size and type. On average, the installation process takes around 2 to 3 days. The initial steps involve a phone consultation, system design, price determination, and estimation of annual electricity generation. Thorough on-site visits precede the installation to address any questions and finalise details with your preferred installer.

Return on Investment and Maintenance:

The return on investment for solar panels varies based on system size, with an estimated payback period of 7 to 10 years. Solar panel systems are generally maintenance-free, but providers often offer cleaning and inspection services if needed.

Grants for Solar PV Panels in Ireland:

The SEAI provides grants based on the peak performance of installed systems in kilowatts. At the time of writing, customers can expect grants of €900 for each kilowatt installed up to 2kW and an additional €300 for each additional kW up to 4kW, with a maximum grant of €2400. In January 2024, the size of the Domestic Solar PV grant will be capped at €2,100, with grants reduced on a pro-rata basis.

As the world continues to embrace renewable energy solutions, residential solar panels offer homeowners an opportunity to reduce electricity costs and contribute to a sustainable future. With various options, installation considerations, and available grants, harnessing solar power has become an accessible and viable choice for those looking to make their homes more energy-efficient.
