Installing Solar on Rented Properties: What You Need to Know

Installing solar panels on rented properties is becoming increasingly popular in Ireland as landlords look for ways to reduce running costs, improve BER ratings, and make their properties more attractive to tenants. However, rental properties come with additional legal, financial, and practical considerations that do not apply to owner occupied homes.

This guide explains what landlords and tenants need to know before installing solar panels on a rented property, including permissions, responsibilities, grants, and long term benefits.

Can You Install Solar on a Rented Property?

In most cases, only the property owner can authorise permanent building works such as solar panel installations. Tenants cannot install solar panels without written consent from the landlord, as panels are fixed to the roof structure and connected to the home’s electrical system.

For landlords, installing solar is usually straightforward provided the property meets structural and regulatory requirements.

Legal and Tenancy Considerations

Before installing solar on a rental property, landlords should review:

• Lease agreements and tenancy terms
• Responsibilities for maintenance and repairs
• Access arrangements for inspections and servicing
• Insurance coverage for renewable energy systems

It is advisable to document any solar installation in the tenancy agreement to avoid disputes over access, usage, and future upgrades.

The Residential Tenancies Board outlines landlord responsibilities for maintaining rental properties and ensuring they meet minimum standards, which can include safe electrical systems and structural integrity.

Who Pays and Who Benefits?

One of the main challenges with rental property solar is the split between who pays and who benefits.

Landlord Pays, Tenant Benefits

If the landlord funds the installation, tenants usually benefit from lower electricity bills. This can:

• Increase tenant satisfaction and retention
• Reduce vacancy periods
• Support higher long term rental value

Passing on Costs

Some landlords factor solar investment into rent levels, especially where energy savings are clearly demonstrated.

Transparent communication helps avoid misunderstandings.

Grants and Financial Support

Landlords may be eligible for certain energy upgrade incentives depending on property use and occupancy. While many SEAI grants are focused on owner occupiers, some schemes may apply in specific circumstances.

System Design for Rental Properties

Solar systems on rented homes should prioritise reliability and low maintenance.

Key design priorities include:

• Durable, high quality panels
• Reliable inverters with strong warranties
• Clear isolation and safety labelling
• Simple monitoring systems

Choosing robust components reduces the risk of tenant disruption and ongoing service costs.

Maintenance and Responsibility

Landlords are typically responsible for maintaining fixed building systems, including solar installations. This usually covers:

• Inverter servicing
• Electrical inspections
• Fault repairs
• Insurance claims

Tenants should be given clear guidance on basic system use and reporting faults.

Impact on BER Ratings and Property Appeal

Solar panels can improve a property’s Building Energy Rating, making it more attractive to energy conscious tenants. A better BER can also support long term property value.

Solar and EV Charging in Rental Properties

Some landlords also consider installing EV chargers alongside solar systems. While this adds value, it requires careful planning around metering, access, and billing.

Tax and Accounting Considerations

Solar installations on rental properties may qualify as capital improvements for tax purposes. Landlords should consult an accountant regarding:

• Capital allowances
• Depreciation
• Expense treatment
• Impact on rental income reporting

Professional advice ensures compliance and maximises financial benefits.

Final Thoughts

Installing solar on rented properties in Ireland can deliver strong long term benefits for landlords and tenants alike. Lower energy costs, improved BER ratings, and increased property appeal all contribute to better rental performance. However, success depends on proper permissions, clear agreements, and professional installation.
