Top Solar Installers in San Antonio - 2026 Rankings

Not all solar companies are equal. In San Antonio, you want someone who knows CPS Energy territory and local permitting.

Red flags when choosing a solar installer

We analyzed thousands of solar company reviews. The top complaints: poor communication, delayed installations, and companies that disappear after the sale. These aren't edge cases - they're patterns you can avoid by knowing what to look for.

How do I choose a solar company?

Years in business. 5+ is good. 10+ is better.

Local presence. They should know San Antonio permitting.

Warranty coverage. 25 years on panels, 10+ on labor.

Reviews. Check Google, Yelp, BBB.

Red Flags from Real Reviews

After analyzing 1,400+ negative reviews, these are the warning signs:

Complaints about 'pushy sales' or 'pressure tactics'

Reports of 'delays' lasting months or years

Issues with 'billing' that never got resolved

Damage to 'roof' during installation

How to ensure your installer keeps you updated

The #1 complaint in solar reviews: "They won't call me back." This happens more than you'd think. A good installer responds within 24-48 hours. If you can't reach them before the sale, imagine trying to get warranty service after.

What should I know before signing a solar contract?

Who handles the CPS Energy interconnection paperwork?

What's your warranty on workmanship?

Are your installers W-2 employees or subcontractors?

Do your battery systems qualify for grid services programs?

Price-Match Guarantee: We match any legitimate quote on equivalent equipment. You get competitive pricing without the stress of endless negotiations. True Transparency: Our quotes show exactly what you're paying for. No hidden fees. No surprise add-ons. What you see is what you pay.
