Extra Costs to Consider

When planning for solar energy, remember that expenses go beyond equipment and installation. Costs like roof work, maintenance, and battery storage can significantly affect your overall investment.

Solar Roof Requirements

Before installing solar panels, ensure your roof is in good condition to avoid surprise costs later. A professional roof inspection can help spot any issues early on. If repairs are needed after installation, removing panels can cost $200 to $300 per panel – or roughly $2,800 to $4,800 for a system with 14 to 16 panels. Replacing a shingle roof on a 1,500 sq. ft. home typically costs about $6,960. If you opt for solar shingles instead, expect a price range of $31,500 to $37,500 for the same roof size. Keep in mind, you’ll also need to budget for future maintenance beyond roof repairs.

Solar Upkeep and Repair Costs

Regular maintenance is essential for keeping your solar system running efficiently and extending its lifespan. Annual upkeep usually costs between $300 and $850. Key tasks include:

• Panel cleaning: Costs range from $150 to $500 (or about $10–$20 per panel), while inspections are typically $150 to $350.
• Service call fees: Expect to pay between $100 and $250.

Common repairs include:

• Fixing broken glass: $20 to $450
• Wiring repairs: $100 to $400
• Inverter replacement: $1,500 to $3,000

Since dirt and debris can reduce energy output by as much as 30%, regular cleaning and inspections are crucial for maintaining efficiency. Many maintenance contracts include these services, offering a convenient way to keep your system in top shape. Also, consider the cost of battery storage to fully understand your solar investment.

Solar Battery Storage Options

Adding battery storage gives you a backup power source during outages or when production is low. Here’s a breakdown of typical costs:

• A 5 kWh battery: Around $6,500 before incentives, dropping to $5,000 after the tax credit.
• A 13.5 kWh battery: Approximately $17,550 before incentives and $13,500 after.
• A 20 kWh battery: Roughly $26,000 before incentives and $20,000 after.

Popular battery options and their estimated prices include:

• Tesla Powerwall: $9,200
• Enphase IQ 10: $10,000
• SolarEdge Home Battery: $9,000
• LG Chem Prime: $9,500

On average, battery storage costs about $1,300 per kilowatt-hour before incentives, dropping to $1,000 after applying the federal tax credit. A typical battery can power essential appliances for over 8 hours without needing a recharge. DC batteries are often more budget-friendly, while AC batteries are usually easier to integrate with existing systems. When choosing a battery, consider your energy usage, available incentives, and utility rates to find the best fit.

2025 Solar Incentives and Savings

Solar Federal Tax Credit Details

The Residential Clean Energy Credit provides a 30% tax credit on the total cost of your solar installation. For example, if your solar system costs $20,000, you could receive a $6,000 tax credit to reduce your federal taxes.

This credit covers a range of clean energy equipment, such as:

• Photovoltaic solar panels
• Battery storage systems
• Solar water heaters
• Geothermal heat pumps
• Wind turbines
• Fuel cells

"You can claim the full cost of the solar panels if you finance instead of purchasing outright; however, financing costs and interest are not eligible."

The 30% tax credit is available through 2032. It then drops to 26% in 2033, 22% in 2034, and will no longer be available after 2035. To qualify, you need to:

• Purchase the system (either with cash or a loan)
• Have enough taxable income to claim the credit
• Install the system at your primary or secondary residence
• Obtain utility Permission to Operate (PTO) within the tax year you’re claiming the credit

Beyond federal incentives, state and local programs can further reduce your costs.

Local and State Programs

State and local initiatives can help lower your solar expenses through property and sales tax exemptions, SRECs, PBIs, and utility rebates. Here’s a look at some programs:

Other benefits include:

• Property tax exemptions for solar installations
• Sales tax exemptions, saving between 4% and 7%
• Solar Renewable Energy Certificates (SRECs)
• Performance-Based Incentives (PBIs)
• Rebates from utility companies

Utility Bill Savings

In addition to tax credits and local incentives, installing solar panels can significantly reduce your utility bills. Homeowners typically see:

• Average yearly savings of $1,390 (based on $0.13 per kWh)
• Lifetime savings ranging from $10,000 to $30,000

Ways to Pay for Solar Panels

Direct Purchase vs. Loans

Buying solar panels outright offers the most long-term savings. In 2025, the average cost of a home solar system is $29,360 before incentives and $20,552 after applying the federal tax credit. While this requires a substantial upfront investment, it avoids any financing costs.

On the other hand, solar loans let homeowners pay over time, but they come with added interest. In fact, financing can increase the system’s lifetime cost by up to 47%. For example, a $29,360 system could end up costing around $43,159 over its lifetime.

Here’s a quick breakdown of the pros and cons of each:

If upfront costs are a concern, other options like solar leases and Power Purchase Agreements (PPAs) might be worth exploring.

Lease and PPA Options

With a PPA, a third party handles installation, ownership, and maintenance of the solar system. You then buy the electricity it generates at a pre-agreed rate.

"A solar lease or PPA requires that you either pay it off or that the new buyer agrees to pay the monthly payments and take over the contract. This is more difficult in terms of a home sale than a system that you own that transfers with the home."
– Roger Horowitz, director of Go Solar programs at Solar United Neighbors

These arrangements differ significantly from owning a system outright, as summarized below.

Payment Method Comparison

Here’s a comparison of the key financial aspects of different payment methods:

With electricity prices rising 6.2% from 2022 to 2023, owning a solar system becomes more appealing for long-term savings. Plus, homes with solar panels tend to sell 20% faster than those without, particularly when the system is owned outright.

"PPA applications can often be approved and signed in a single meeting."
