Going solar is a big decision—and choosing the right system requires more than just comparing price tags. To ensure you get the most from your investment, here are the top questions to ask before committing to a solar package, and why each one truly matters.
1. What’s Included in the Solar Package?
🔍 Why It Matters
Some solar offers look budget-friendly—but they may exclude essential elements like inverters, mounting hardware, permits, or inspections. Understanding what’s included helps you compare apples to apples.
Things to Clarify
Are panels, inverters, racking, wiring, and shipping included?
Does the system cover permits, inspections, and utility interconnection?
Are there add-ons like monitoring, smartphone apps, or homeowners’ insurance implications?
Make sure the solar installer explains each component clearly. If any piece is missing—or hidden—it could add hundreds or thousands of dollars to your final cost.
2. What Panel Brand and Efficiency Level Are You Offering?
🔍 Why It Matters
Not all solar panels are created equal. Higher-efficiency panels generate more power in less space, are better suited to small or shaded roofs, and tend to be more durable over time.
Ask About:
Panel wattage (e.g., 350 W vs. 410 W) and efficiency ratings (20%+ preferred)
Warranty coverage (25+ years is standard for power production)
Tier 1 vs. Tier 2 brands (trusted manufacturers vs. budget panels)
You can find helpful background information in the Department of Energy’s home solar guide —and it’s a great resource to compare what’s being offered to what you’re quoted.
3. Will You Include a Battery Backup or Service Panel Upgrade?
🔍 Why It Matters
If you’re considering energy independence, emergency backup power, or resilience during outages, you’ll need either a home battery or a panel upgrade—and the system should be designed accordingly.
Points to Cover:
Are storage options (like Tesla Powerwall) included or offered as an add-on?
Does your current electrical panel meet code, or is an upgrade required?
Can the system support critical loads during outages?
Designing the system with battery backup in mind upfront is far easier (and safer) than retrofitting it later. Poor integration can lead to reduced performance, code violations, or higher costs down the line.
4. What Are the Financing Options and Incentives?
🔍 Why It Matters
Solar isn’t just about lowering energy bills—it’s also about using financing and incentives to maximize ROI. Many options exist, and the support you receive in navigating them can make a big difference.
Ask:
Do you offer financing, solar loans, or leasing?
Will you help with local/state/federal incentives, like rebates or tax credits?
Are ongoing service plans or warranty upkeep included—and what’s the cost?
Jonas Energy is proud to help connect customers with financing options and rebates, smoothing out upfront expenses and long-term ownership.
5. Who Handles Design, Permits, and Inspection?
🔍 Why It Matters
A solar project isn’t just panels and inverters—they also require engineering, electrical inspections, and utility approvals. Errors in design or permitting can cause delays, fines, or safety issues.
Questions to Ask:
Do you handle engineering drawings and calculations?
Will you file permit applications and secure approvals?
How long after installation will inspections and the final sign-off happen?
If you’re ever not sure, reminder: getting the right paperwork upfront saves you headaches later—and keeps the utility company happy.
6. What Is the Expected System Performance?
🔍 Why It Matters
It’s easy to buy a solar system—but tough to expect reliable energy output. Estimates need to account for your roof orientation, shading, location, and panel losses.
Topic Checklist:
Provide annual kWh output estimate, based on your site.
Explain production ratio—how much energy you’ll produce per kW installed.
Offer monitoring options to track real-time performance.
Solar monitoring isn’t just a nice-to-have—it’s essential. It helps spot malfunctions or underperformance, so you get the system’s value in full.
7. What Is Included in the Warranties and Long-Term Support?
🔍 Why It Matters
A solar system lives for 25+ years, so you’ll want a partner who stands behind their work long-term—not just the installation.
Warranty Must-Haves:
Panel power warranty (at least 25 years, 80%+ output guarantee)
Equipment warranty on inverters and racking (10+ years common)
Workmanship guarantee (5–10 years recommended)
Emergency or routine monitoring plans?
Jonas Energy offers robust warranty packages, including ongoing support and regular checkups, ensuring system health and peace of mind.
8. Are You Licensed, Local, and Responsive?
🔍 Why It Matters
Local knowledge, licensing, and customer service make a world of difference—especially when it comes to quick support or emergency repairs.
Look For:
California C-10 or C-46 solar-specific contractor license
Local presence— live service crew, offices, and accessibility
References, reviews, and case studies from Lake County or nearby homes
Jonas Energy handles solar panel and battery installations, panel upgrades, and service throughout Lake County—with live phone support, online scheduling, and a reputation built over 70+ years of service.
9. What Timeline Can I Expect?
🔍 Why It Matters
Delays in any stage—from permits to inspection—can push your system off-season, hurting energy production and ROI.
Timeline Checklist:
Site assessment date (within 1–2 weeks)
Time to issue permits and utility interconnection (typically 4–8 weeks)
Installation window (1–2 days for most residential jobs)
Inspection and activation timeline (final sign-off within 1–3 weeks)
Ask for a site-level timeline from your installer so you’re never left guessing when your system will go live.
10. How Will My Home’s Value and Energy Bill Change?
🔍 Why It Matters
Solar can increase your home’s resale value—and dramatically reduce your monthly power bills—but you should know how to predict these benefits.
Metrics to Request:
Estimated annual energy savings (based on your current usage)
Approximate increase in home equity from solar
Break-even projections: How many years until the system pays for itself?
While every home is different, a well-sized solar system can slash electricity bills and even add 3–4% in resale value—especially in California’s sunny market.
