Solar FAQ: Straight Answers to the Hard Questions

No sales pitch. No green marketing. Just straight answers to the questions skeptical homeowners are actually asking.

Aren’t most solar panels made in China?

Yes — and that’s exactly the problem.

China controls over 80% of global solar panel manufacturing, including most of the silicon wafers and cells used in panels branded by American and European companies. Many “American solar companies” are just selling Chinese-manufactured product.

But you have a choice. First Solar manufactures in Ohio. Q CELLS manufactures in Dalton, Georgia. Auxin Solar manufactures in California. American-made panels exist, they’re competitive, and buying them qualifies you for a 10% bonus on top of the standard 30% federal tax credit.

Ask your installer: “Where is the panel manufactured?” Not where the company is headquartered. Where the factory is.

Isn’t the solar tax credit a government handout?

No. It’s YOUR tax dollars coming home.

The 30% Investment Tax Credit has been part of federal tax law since 2006. You’ve been paying taxes your whole life. This is the IRS giving you a credit — a direct reduction in what you owe — for making a specific kind of capital investment.

Your neighbors who installed solar got $7,200 back on a $24,000 system. That money came from the same pool of federal tax revenue you contribute to. You’re not taking a handout — you’re reclaiming money from a system you’ve paid into.

The honest framing: if you DON’T take the ITC, you’re voluntarily overpaying your taxes while your neighbors pocket the difference.

How long does it actually take to pay off?

Typically 6–12 years. The system lasts 25–30.

The “payback period” depends on:

• Your local electricity rate (higher = faster payback)
• Your annual rate of increase (documented average: ~3.5%/year per EIA)
• Your system size relative to usage
• Your federal tax credit (30% baseline, 40% with American-made panels)
• Your state incentives

NREL benchmarks a typical residential system payback period between 6–12 years. After payback, you’re generating free electricity — for 15–20 more years.

Over a 25-year system life at 3.5% annual rate escalation, a family currently paying $150/month saves $75,000+ compared to staying on grid power. The ROI typically runs 8–15% — better than most bonds, comparable to average stock market returns, with no market volatility.

State your assumptions explicitly when running numbers. Verify your specific situation with a local installer. Individual results vary.

What if electricity rates go DOWN?

They haven’t, and there’s no structural reason they will.

The EIA’s historical data shows US retail electricity prices have increased in 22 of the last 25 years. The structural drivers — aging grid infrastructure requiring capital investment, increasing demand from electrification, monopoly rate structure that rewards capital spending — point to continued increases.

Could rates drop? Theoretically. Natural gas price crashes have occasionally slowed rate growth. But a utility with a guaranteed rate of return has no incentive to pass savings through to customers. The PUC process means any decrease in fuel costs can be offset by a rate case for infrastructure investment.

If you’re betting against 25 years of documented rate history: it’s your bet to make. Run the numbers at current rates and decide.

My HOA says no. Can I still go solar?

In 44 states: yes.

Forty-four states have passed some form of solar access law that limits or prohibits HOA restrictions on solar installations. Your HOA may not know this, or may be hoping you don’t.

Key steps:

1. Look up your state’s solar access law at DSIRE (dsireusa.org)
2. Send a written request to your HOA citing the applicable statute
3. Your HOA can typically require “reasonable” aesthetic restrictions (placement, color of panels, equipment screening) but cannot outright prohibit solar

Florida, California, Texas, Arizona, and most other major solar states have strong solar access laws. Verify your state’s specific provisions — strength varies significantly.

Will my power go out when the grid goes down?

Standard grid-tied systems yes — unless you add battery backup.

A standard grid-tied solar system (no battery) is required by law to shut down during a grid outage. This is a safety measure — utility workers need to know the lines are dead.

With battery storage (e.g., Tesla Powerwall, Enphase IQ Battery, Generac PWRcell): Your system can island from the grid and continue powering your home during an outage. You generate and store during the day; you run critical loads overnight.

The economics of battery storage have improved significantly. A Tesla Powerwall + solar system qualifies for the same 30% ITC as the solar equipment. If grid reliability is a concern, batteries are the answer — and the tax credit applies.

Are the technology and warranties reliable?

Yes. Solar is mature technology.

The first commercial silicon solar panels were produced in the 1950s. Modern crystalline silicon panels have been commercially available since the 1970s. The technology is not experimental.

Modern tier-1 panels carry:

• 25-year production warranties (guaranteeing 80–90% of rated output at 25 years)
• 10–12 year product warranties (against defects)
• Independently certified by UL, IEC, and other testing bodies

NREL has tracked the reliability of deployed solar systems and found median annual degradation rates of 0.5% per year — meaning a panel rated 400W today would still produce ~380W after 10 years.

Ask your installer for the specific warranty terms. Make sure they’ll still be in business to honor them.

What permits do I need?

A building permit and utility interconnection agreement — your installer handles both.

Any legitimate residential solar installer pulls the permits. If an installer offers to “skip the permit to save money,” walk away. Unpermitted solar creates problems when you sell your home and can void your homeowner’s insurance.

The typical process:

1. Installer submits permit application to your local building department
2. Building department reviews plans (1–4 weeks typically)
3. Inspector visits after installation for final approval
4. Utility interconnects your system (1–8 weeks depending on utility)

Ask your installer: “Do you pull all permits and handle interconnection?” The answer should be yes.

Does solar work in cold/cloudy climates?

Yes — solar generates from light, not heat. Cloudy doesn’t mean dark.

Germany — one of the cloudiest countries in Europe — is among the world leaders in solar adoption. New England and the Pacific Northwest have significant solar installations despite their reputations for clouds.

Cold temperatures actually improve panel efficiency — panels produce more watts per hour of sunlight in cold weather than in hot weather. Snow can temporarily cover panels, but it slides off quickly.

NREL’s PVWatts calculator (pvwatts.nrel.gov) lets you enter any US address and see estimated production based on decades of actual solar resource data. Use it. It’s free, government-produced, and more accurate than anything a salesman will tell you.

The relevant question is not “Is my climate good?” but “How many peak sun hours does my location average?” NREL’s data answers this for every county in the country.
