Five questions Irish homeowners should ask before buying renewable energy technology

What is Smart Technology?

As sustainability and energy efficiency become more critical, many Irish homeowners are considering purchasing renewable energy technologies such as solar PV, heat pumps and electric vehicles. These technologies can help decrease carbon footprints, reduce the cost of energy in the home and encourage smart behaviours.

1. What combination of technology is best suited for my home, lifestyle and energy use?

Choosing the right renewable energy system depends on various factors, including location, energy needs, and available space.

Considerations: 

• Roof and Land Space: Evaluate your roof’s orientation and size for solar panels or yard space for the outdoor heat pump unit. Your installer will be able to help you assess the area and make a recommendation. 
• Lifestyle: How does your work/commute affect your energy use and time of energy use?

2. What Are the Initial Costs and Long-Term Savings?

Considerations:

• Installation Costs: Get a detailed breakdown of installation costs, including equipment and labour.
• Maintenance Costs: Ask about ongoing maintenance and associated costs.
• Payback Period: Calculate the time it will take for energy savings to cover the initial investment.

Grants are available for different energy upgrades and technologies. This will help with the upfront costs of purchase. The return-on-investment can be improved with 'time of use tariffs' and and smart behaviour. Explore available grants, tax incentives, or rebates, offered with SEAI.

3. What Is the Expected Lifespan and Warranty of the System?

Renewable energy systems are long-term investments, so understanding their durability and warranty is important. 

Considerations:

• Lifespan: Inquire about the system’s operational lifespan. Solar panels typically last 25-30 years.
• Warranty: Ask for details on warranty coverage for both equipment and installation. Heat pumps generally have a warranty of 5-7yrs. Check with your supplier.

Performance Guarantees: Some suppliers offer guarantees on the system’s energy production over its lifespan. Furthermore, understanding how much this technology will improve your home’s BER is important and will help increase the value of your home.

Maintenance: For example, Solar panels involves occasional cleaning to get rid of dust and debris and inspecting electrical connections. If you take proper care of your solar panels, they can last for longer.

4. How Will This Integrate with My Existing Energy Infrastructure?

Seamless integration with your current home smart setup maximizes the benefits of renewable technology.

Considerations:

• Suitability to your Home: Ensure the new system is compatible with your existing electrical infrastructure.
• Becoming a Smart Home: If you have or plan to have a smart home, check the system’s integration with smart devices and applications.
• Grid Connection: Understand how the system will connect to the national grid managed by ESB Networks, including options like net metering to sell excess power back to the grid.

5. What Are the Environmental and Social Benefits?

Beyond cost savings, renewable energy systems offer significant environmental and social advantages.

Considerations:

• Carbon Footprint Reduction: Request an estimate of how much the system will reduce your household’s carbon footprint.
• Energy Independence: Understand how the system will contribute to reducing your reliance on non-renewable energy sources and assist in your journey in being a complete smart home.

Transitioning to renewable energy technology is a significant step toward sustainability and energy efficiency and security. By asking these essential questions, Irish homeowners can make informed decisions, ensuring they choose the best system for their needs, budget, and environmental goals. Being well-informed and proactive will help maximise the benefits of your investment, contributing to a greener future for your home and community.
