Last updated July 2026
Tesla Solar
The lowest-price name-brand residential solar installer
Advantages
- Lowest price per watt among major installers ($2.20-$2.80/W installed)
- Deep integration with Tesla Powerwall battery storage
- Powerwall bundles unlock Tesla Electric net-metering-plus programs where available
- Sleek, low-profile panels manufactured in-house
- Fully digital ordering process through the Tesla app
Drawbacks
- Widely reported slow installation timelines (3-9 months)
- Customer service is notoriously hard to reach
- Limited installer network in some states
- Warranty support experience is inconsistent
Sunrun
America's #1 home solar installer with in-house crews
Advantages
- Largest residential solar installer in the U.S.
- In-house installation crews in most major metros
- Strong equipment and workmanship warranties
- Multiple financing options: cash, loan, lease, PPA
- Brightbox by LG battery bundle available
Drawbacks
- Pricing higher than Tesla ($3.00-$3.80/W)
- Lease and PPA options can complicate future home sales
- Installation timelines 3-6 months (still faster than Tesla on average)
Tesla Solar undercuts the industry on price ($2.20-$2.80/W) but has a reputation for slow installation and poor communication. Sunrun is the largest residential solar installer in the U.S. with in-house crews and multiple financing options. Cheap and slow versus expensive and reliable.

Sunrun Wins
Sunrun wins for most homeowners despite the higher price, Tesla's installation and support issues offset the cost savings for many buyers.
Tesla's $4K-$6K savings on a typical 8kW system is real, and if you're patient and technically savvy, the numbers can work. But the sustained pattern of slow installs and difficult customer service means Sunrun's premium buys real peace of mind. Choose Tesla if you specifically want a Powerwall-integrated system and are OK managing a slow install. Choose Sunrun otherwise, or get quotes from both and a local installer to see if you can beat both prices.
