Energy Efficiency Loans For Good and Bad Credit

What are energy efficiency loans?

Energy efficiency loans are financing options that allow you to pay for upgrades that improve your home’s energy performance. Instead of covering the entire cost upfront, you can spread payments over a set term, often with fixed monthly installments.

While some programs offer specialized financing for energy upgrades, some homeowners use personal loans. Personal loans can be used for a wide range of projects, give you the flexibility to choose your contractor or supplier, or finance more than one project, and don’t require your home as collateral.

Common projects funded with energy efficiency loans include:

• Installing solar panels or battery storage systems
• Replacing HVAC systems with high-efficiency models
• Upgrading to Energy Star–rated appliances
• Adding insulation or replacing windows and doors
• Installing smart home energy management systems

What can I use an energy efficient loan for?

An energy efficient loan can be used for almost any home improvement that reduces energy consumption or improves sustainability. Examples include:

• Solar installations: Panels, inverters, and storage batteries
• Appliance upgrades: Energy Star–rated refrigerators, washers, dryers, and dishwashers
• Heating and cooling systems: High-efficiency furnaces, heat pumps, or air conditioners
• Weatherization improvements: Insulation, air sealing, and energy-efficient windows or doors
• Water heating: Tankless or solar water heaters
• Lighting upgrades: LED retrofits for whole-home efficiency

Because personal loans aren’t tied to specific vendors, you can bundle multiple improvements into one project and one loan.

How do energy efficiency loans work?

When using a personal loan for an energy-efficient project, the process is straightforward:

1. Check offers — Through Acorn Finance, you can compare offers from multiple lenders in minutes with no impact to your credit score. Alternatively you can shop offers directly with local or online lenders.
2. Select your loan — Choose the offer that best fits your needs and budget.
3. Obtain approval - Accept an offer to complete the approval process with the lender.
4. Receive funds directly — Once approved, the full loan amount can be deposited into your account, usually within 1–2 business days, although funding times may vary.
5. Pay for your upgrades — Hire contractors, purchase equipment, or schedule installations on your timeline.
6. Repay in fixed installments — Make predictable monthly payments until the loan is paid off.

This flexibility allows you to control the scope of your project and negotiate directly with suppliers or contractors.

Are energy efficient loans available for bad credit?

Yes — while higher credit scores typically qualify for more competitive offers, some lenders are willing to work with borrowers who have less-than-perfect credit. If your score is lower, lenders may also consider:

• Your income and employment stability

• Your debt-to-income ratio

• Your history of on-time payments

• Whether you can add a co-signer with strong credit

Some lenders, such as OneMain Financial — an Acorn Finance lending partner — do not have a minimum credit score requirement. Instead, they place more emphasis on factors like income and overall financial stability to determine eligibility.

Do energy efficiency loans require home equity?

Not necessarily. While some energy improvement financing — such as certain government or utility programs — may require home equity or be tied to your property taxes, personal loans do not. Personal loans are unsecured meaning they do not require collateral. 

Can I save money with an energy efficiency loan?

Yes — in many cases, the monthly savings on your utility bills can help offset part of your loan payment. For example:

• Installing solar panels may significantly reduce or even eliminate your electricity bill.
• Replacing old HVAC equipment with a high-efficiency system can lower heating and cooling costs.
• Upgrading insulation and windows can reduce heating and cooling loss, saving energy year-round.

Over time, these savings can add up — and once your loan is paid off, you’ll enjoy the full financial benefit of reduced energy costs.
