As a real estate professional working with homebuyers and sellers in Northern Colorado, where the sun shines an average of 300 days per year, ☀️ I often hear questions about solar panels. Buyers and sellers alike wonder if solar systems are worth the investment, how they impact property values, and what’s involved in a transaction when a home has solar. If you’re considering buying or selling a solar-equipped home, this guide will walk you through what to know about the technology, financial options, and the steps involved for everyone in the transaction.
1. Should You Buy or Pass on Solar?
Solar can add value to a property, but the decision to buy (or not) depends on a few key factors:
Long-Term Savings: Solar panels often reduce energy costs, which can be appealing. However, check the local utility rates, the home’s energy efficiency, and the system’s capacity to understand the real savings. Janelle McGill, an advocate for solar energy, says that it takes about 7 years to break even on the cost of adding a solar system against the cost of the utilities. There are a few variables, but this is a general rule of thumb.
Environmental Impact: Solar energy is clean, renewable, and attractive to eco-conscious buyers looking to reduce their carbon footprint. However, it's also important to consider what happens to panels once they reach the end of their useful life. While panels typically last 25–40 years, disposal and recycling are growing concerns as solar becomes more common.
Many solar panels can be recycled, with materials like glass, aluminum, and certain metals recovered for reuse. However, the recycling process can be costly and complex, so currently, only a limited number of specialized facilities handle it. Fortunately, new advances in recycling technology and initiatives to improve end-of-life panel management are in progress. When discussing solar's environmental impact, buyers and sellers should keep this lifecycle aspect in mind, especially as eco-friendly disposal and recycling options continue to expand.
System Age, Condition, and Ownership: Solar panels lose efficiency gradually, so if the system is nearing the end of its warranty period, it’s wise to consider potential replacement costs down the line. However, other factors play a role in deciding if buying a home with solar is a smart investment.
First, consider who owns the system. If the panels are leased, review the lease terms, monthly payments, and conditions for transfer. On the other hand, if the system is owned, it could add property value and allow for immediate savings without ongoing fees.
It’s also essential to check if the system offers a net metering benefit, where homeowners can sell unused energy back to the grid for credits. Net metering arrangements vary by state, but they can significantly increase savings on utility bills. Balancing these factors — age, ownership, and potential savings — will help determine whether buying a home with solar panels is a solid long-term deal.
2. The Lifespan and Obsolescence of Solar Panels
Most solar panels come with a 20–25 year warranty, which usually guarantees around 80–90% efficiency for that duration. After the warranty expires, efficiency typically starts to decline, but that doesn't mean the panels will stop working altogether. In fact, many panels can remain functional for up to 40 years or more, though they may produce less energy over time. This gradual reduction in efficiency is an important consideration for buyers and sellers, as older panels may not deliver the same savings as newer ones.
Understanding these factors helps manage expectations on future energy output and may influence a buyer's decision on whether to keep the existing system or consider upgrades down the line.
3. To Lease or Buy? Pros and Cons
Buying:
Pros: Full ownership means no third-party contracts, and you can likely add to your home’s value. You’re also eligible for tax credits and rebates.
Cons: Higher upfront cost.
Leasing:
Pros: Lower or no upfront cost and can be good for short-term savings.
Cons: The lease agreement often transfers to the buyer, which can complicate transactions.
4. Technical Rundown of Solar Panel Systems
Solar systems usually consist of photovoltaic (PV) panels, inverters to convert solar power to usable electricity, and sometimes battery storage. Panels vary by type, efficiency, and warranty length. Key factors for buyers: power output, panel durability, and inverter type. A basic residential solar system includes:
Solar Panels: Capture sunlight and convert it to DC electricity.
Inverter: Converts DC electricity to AC, which powers the home.
Battery (optional): Stores energy for use during cloudy days or at night.
Monitoring System: Tracks energy production and usage.
5. Understanding the Value of Net Metering
Net metering is a key benefit of solar systems that many buyers overlook. Through net metering, any excess energy your solar system generates is sent back to the grid, and you earn credits on your utility bill. This can significantly reduce or even eliminate monthly energy costs, especially during peak sunny months. For buyers, understanding the net metering arrangement with the local utility company is essential, as it can vary in terms of compensation rates and contract terms. This is a powerful tool for reducing long-term costs and increasing the financial appeal of a solar-equipped home.
6. Financing Options
There are several financing options:
Cash Purchase: Avoids interest but requires a substantial upfront investment.
Loans: Federal and local banks offer loans specifically for solar installations.
PACE Financing: Property Assessed Clean Energy loans, tied to your property tax.
Power Purchase Agreement (PPA): Pay only for the power generated by the system without owning the panels.
7. Rebates and Incentives
Federal and local rebates and tax credits make solar more affordable.
Federal Tax Credits: The federal investment tax credit (ITC) allows homeowners to deduct a portion of solar installation costs. This can be about a 30% off the total cost as a tax credit.
State and Local Incentives: Many states, municipalities, and utility companies offer rebates or credits. Check out the Database of State Incentives for Renewables & Efficiency (DSIRE) for local options.
8. Insurance and Hail Damage Concerns
Colorado’s hailstorms raise concerns for solar. Panels are generally durable, but insurance coverage for solar systems is critical. Most home insurance policies will cover hail damage, but it’s worth double-checking and possibly updating coverage to include solar.
9. A Checklist for Everyone in the Transaction
For the Seller:
System Documentation: Have contracts, warranties, and proof of ownership ready.
Inspection and Maintenance: Get the system inspected to ensure it’s functioning properly.
Transfer Ownership: If leased, make arrangements for a smooth transfer to the new owner.
For the Buyer:
Review Contracts: If the panels are leased, understand the terms.
Inspection: Verify the system’s efficiency and expected remaining lifespan.
Financing Options: Check if you can assume existing financing or need new financing.
For the Listing Agent:
Highlight Solar Benefits: Promote energy savings and eco-friendliness.
Coordinate with Utility Providers: Ensure smooth transfer of any energy credits.
Educate on Value Impact: Understand how appraisers in your market value solar.
For the Selling Agent:
Due Diligence on Lease/Loan Agreements: Research any terms that could impact your client.
Inspect Transfer Requirements: Make sure any financial liabilities are clear to the buyer.
For the Title Company:
Lien Check: If financed or leased, verify if there’s a lien on the system.
Transfer Documentation: Facilitate necessary title and financing transfers.
Solar systems can bring great value but can also complicate transactions if not handled right. As your real estate agent, I’ll take the fear out of the process and ensure you have all the information you need to make a confident, informed decision. Reach out, and let’s navigate the sunny side of real estate together!
