Energy Efficiency Mortgages: Integrate Solar Upgrades with Home Buying

April 28, 20254 min read

When buying a home or refinancing, it’s a golden opportunity to make smart, future-proof upgrades like going solar. And guess what? There’s a mortgage for that. Energy Efficiency Mortgages (EEMs) are specially designed to help homeowners finance solar panels and other energy-saving improvements right alongside their home purchase or refinance. Let’s break down how these loans work, their benefits, and how you can use them to boost your home’s value and efficiency without breaking the bank.

What is an Energy Efficiency Mortgage?

An Energy Efficiency Mortgage is a special type of home loan that includes extra funds earmarked for energy-efficient upgrades. This might include solar panel installations, better insulation, energy-saving windows, or high-efficiency HVAC systems. The logic is simple: homes that cost less to run leave you with more cash to pay your mortgage which is good for you and the lender.

How Do Energy Efficiency Mortgages Work?

Here’s a simple walkthrough:

  • Home Energy Assessment: A certified energy rater evaluates your home to identify where energy improvements (like solar) make sense.

  • Loan Approval: Your lender approves a mortgage that covers both the home and the energy-efficient improvements.

  • Post-Closing Upgrades: Once the deal closes, you’ll have access to the extra funds to complete the solar upgrade or other improvements.

  • Enjoy the Benefits: You immediately start saving on energy bills and your home is more comfortable, eco-friendly, and valuable.

Why It’s Smart to Bundle Solar with Your Mortgage

  • Lower Rates: Mortgage rates are typically much lower than credit cards or personal loans. That means solar costs less in the long run.

  • Spread Out Payments: Instead of paying for solar upfront or over 5–10 years, EEMs let you stretch the cost over your 15–30 year mortgage.

  • Instant ROI: Even though your mortgage might be a little higher, your energy bill drops so you’re saving money right away.

  • One and Done: It’s easier to roll everything into one loan rather than juggling multiple financing options.

Benefits of Energy Efficiency Mortgages

  • Lower Utility Bills: Use less power, save more cash.

  • Increased Home Value: Homes with solar and energy upgrades are more attractive to buyers.

  • Improved Comfort: Energy-efficient homes are better at holding heat in winter and staying cool in summer.

  • Eco-Friendly Impact: Use clean energy and reduce your carbon footprint.

Who Can Qualify for an EEM?

Most buyers or homeowners refinancing can qualify as long as:

  • You meet typical mortgage approval requirements (income, credit, etc.)

  • Your upgrades are cost-effective (your energy audit will prove this)

  • You plan to live in the home as your primary residence

Steps to Get an Energy Efficiency Mortgage

  1. Find an EEM Lender: Not all banks or mortgage brokers offer EEMs. Look for lenders familiar with energy-efficient financing.

  2. Schedule a Home Energy Audit: A certified auditor inspects your home and gives you a list of recommended upgrades (like solar) along with cost and savings estimates.

  3. Submit with Your Loan Application: Include the audit report and quotes for your upgrades when applying.

  4. Close the Loan and Upgrade: Once the deal closes, the funds for energy upgrades are released and the work can begin.

FAQs: What Homeowners Are Asking

Q: Can I use an Energy Efficiency Mortgage for solar only?
A: Absolutely! Solar panels are one of the most popular upgrades financed through EEMs.

Q: What kinds of upgrades can be bundled?
A: In addition to solar, things like insulation, smart thermostats, energy-efficient windows, doors, water heaters, and HVAC systems often qualify.

Q: Are there limits to how much I can finance?
A: The amount you can add to your mortgage varies, but typically it must be equal to or less than the projected energy savings.

Q: Will this slow down my home buying process?
A: Not by much especially if you’re working with a knowledgeable lender and energy rater. A good team can streamline the entire process.
