How to Discern Between Solar Quotes?

Getting multiple solar quotes is a smart way to ensure you’re getting the best deal, but how do you compare them effectively? Here are the key factors to consider when evaluating solar quotes.

1. System Size & Production Estimates

Each quote should specify the system size in kilowatts (kW) and estimate annual energy production in kilowatt-hours (kWh). Make sure the production estimates align with your energy needs and compare projections across installers to see if they are realistic. Confirm that your quote includes your utility rate in order to accurately reflect savings.

2. Equipment Quality & Efficiency

Not all solar panels and inverters are the same. Higher-efficiency panels may cost more upfront but produce more power over time. Check the brand, warranty, and efficiency ratings of the panels and inverters in each quote to ensure you’re getting reliable equipment.

3. Total Cost vs. Cost Per Watt

Compare the total system price, but also break it down into the cost per watt ($/W). This metric helps standardize pricing, making it easier to compare quotes of different system sizes. Be sure to check if the quote includes installation, permits, and additional costs.

4. Incentives & Financing Options

Some installers include federal, state, and local incentives in their pricing, while others list them separately. Make sure you understand what incentives you qualify for. Also, compare financing options like loans, leases, or power purchase agreements (PPAs) to find the best fit for your budget.

5. Warranties & Maintenance

A solid warranty protects your investment. Compare panel, inverter, and workmanship warranties. Industry standards are 25 years for panel performance and 5-12 years for inverters and workmanship. Some companies also offer ongoing maintenance services—check if they are included.

6. Reputation & Customer Reviews

Research each installer’s reputation by reading customer reviews and checking their certifications. Look for companies with a strong track record, NABCEP certification, and positive feedback from homeowners in your area. Going solar is a long-term relationship and your workmanship warranty is only good if your installer is still around!

7. Contract Terms & Hidden Fees

Read the fine print. Some contracts include escalator clauses that increase payments over time. Also, watch for hidden fees related to installation, permitting, or grid connection. If anything seems unclear, ask for clarification before signing.

Final Thoughts

Choosing a solar installer isn’t just about price—it’s about quality, reliability, and long-term savings. By carefully comparing system specs, warranties, costs, and company reputation, you can make an informed decision and maximize the benefits of going solar.
