Best Solar Companies in 2026: National Rankings and How to Choose

Choosing a solar installer is as important as choosing the panels themselves. A poor installation from a top-brand panel company will underperform and leave you fighting warranty claims. An excellent installation from a lesser-known installer will run trouble-free for 25 years.

This guide ranks the top national solar companies in 2026 and explains what distinguishes them — and where each falls short.

How We Ranked These Companies

We evaluated installers on five criteria:

1. Pricing — cost per watt installed versus market average
2. Customer satisfaction — BBB ratings, Google reviews, Trustpilot, and pattern of complaints
3. Equipment quality — panel and inverter brands typically offered
4. Warranty coverage — workmanship warranty length, production guarantees, equipment warranty facilitation
5. Financing options — cash, loan, lease, PPA availability and terms

The Rankings

1. Blue Raven Solar (Now Part of SunPower)

Best for: Straightforward cash/loan purchases with competitive pricing

Operating states: 20+

Pricing: Competitive — typically $2.80–$3.60/watt

Warranty: 25-year workmanship

Customer reviews: Above average

Blue Raven was acquired by SunPower in 2021 and continues operating under its own brand in many markets. Unlike SunPower's premium panel positioning, Blue Raven uses a range of tier-1 panels at more competitive price points. Customer satisfaction scores are consistently above national average.

Watch for: Post-acquisition service continuity in some markets has been inconsistent. Verify the local team structure before signing.

2. Palmetto Solar

Best for: Technology-forward homeowners who want strong monitoring and energy management

Operating states: 25+

Pricing: Mid-range — $3.00–$3.80/watt

Warranty: 25-year workmanship, production guarantee

Customer reviews: Strong (4.5+ stars across major platforms)

Palmetto's biggest differentiator is its Protect plan — ongoing monitoring, maintenance, and service for a monthly fee ($30–$50/month). For homeowners who want someone managing the system long-term without buying a lease, this is compelling.

Palmetto uses quality tier-1 equipment (Q Cells, Enphase) and handles in-house design, permitting, and installation in most markets.

3. Sunrun

Best for: $0-down lease/PPA customers who want no ownership responsibility

Operating states: 22+

Pricing: Above-market for purchases ($3.50–$4.50/watt), competitive for leases

Warranty: Full coverage under lease agreements

Customer reviews: Mixed — strong in CA, MA, NJ; weaker in AZ, TX

Sunrun is the largest residential solar installer in the US. Its lease product is its flagship offering — no money down, Sunrun owns and maintains the system, you pay for electricity production.

The lease comes with real strings (20–25 year contract, home-sale complications, annual escalators). For customers who evaluate and accept these terms, Sunrun delivers reliable service. For customers who want ownership, Sunrun's purchase pricing is above-market.

4. Sunnova

Best for: Long-term service agreements and battery storage integration

Operating states: 35+ (widest national reach)

Pricing: $3.20–$4.20/watt for purchases

Warranty: 25-year service agreement available

Customer reviews: Average — similar mixed pattern to Sunrun

Sunnova's widest geographic reach makes it a viable option in markets where other national companies do not operate. Its 25-year "Sunnova+" service agreement (monthly fee) covers all maintenance, monitoring, and repairs without a lease structure — closer to Palmetto's model.

Battery storage (Tesla Powerwall, Sonnen) integration is a strength, particularly for customers pursuing solar+storage in a single project.

5. ADT Solar (Formerly Sunpro Solar)

Best for: Homeowners who want the backing of an established national brand with existing home security relationships

Operating states: 22+

Pricing: $2.80–$3.60/watt

Warranty: 25-year workmanship

Customer reviews: Above average

ADT Solar leverages ADT's nationwide service infrastructure for monitoring and maintenance support. This is a genuine advantage — ADT has existing infrastructure and technician networks in most metro areas. Post-install responsiveness tends to be better than pure-play solar companies in some markets.

6. Trinity Solar

Best for: Northeast homeowners (MA, NJ, CT, NY, PA)

Operating states: Northeast focus (8 states)

Pricing: Competitive — $2.70–$3.40/watt

Warranty: 25-year workmanship

Customer reviews: Strong in core markets

Trinity Solar is technically a regional company but deserves national mention for its consistent above-average reviews in the competitive Northeast market. If you are in Massachusetts, New Jersey, Connecticut, or New York, Trinity should be in your quote pool. Pricing is below most national competitors in these markets.

Why Local Installers Often Win

Every homeowner who has compared quotes knows the pattern: local installers routinely come in 10–25% below national companies for identical equipment.

There are legitimate reasons national companies cost more: marketing, centralized call centers, regulatory compliance teams, investor return requirements, sales commissions. None of these benefit you as the buyer.

When national installers are worth the premium:

• You specifically want a lease/PPA product (fewer local companies offer these)
• You value brand stability for a 25-year relationship (reasonable concern)
• Local installer options in your market are very limited or have poor reviews

When local installers win:

• You are purchasing (cash or loan)
• Local reviews are strong and the company has 5+ years in your market
• You prefer direct relationships for post-install questions

How to Find Good Local Installers

EnergySage: The most reliable source for comparing vetted local installers. All installers on the platform are pre-screened for licensing, insurance, and NABCEP certification. You see multiple quotes in an apples-to-apples format.

NABCEP installer directory: The North American Board of Certified Energy Practitioners maintains a directory of NABCEP-certified installers. NABCEP certification is the industry's most rigorous credential.

State-specific databases: Many state energy offices maintain approved installer lists (required in some states for state incentive eligibility).

Red Flags to Screen For

Before signing with any installer, national or local:

• No physical address or local office — installers who cannot give you a verifiable local presence are higher risk
• Skipping permits — any installer who proposes unpermitted work is a liability, not a savings
• High-pressure same-day offers — "this price expires tonight" is a sales tactic, not a real deadline
• No NABCEP certification for the crew lead — verify credentials
• Vague warranty language — "covered for life" without specific terms is not a warranty

The Bottom Line

The best solar installer for your home is the one that offers the best combination of price, reviews in your specific market, and financing terms that fit your situation. A national brand name is not a guarantee of quality. A local company without reviews is a risk.

The most reliable strategy: use EnergySage to generate 3–4 quotes from a mix of national and local installers, verify NABCEP credentials on each, and check Google reviews from the past 12 months in your city.
