Panel Options

Sunrun’s solar panel selection includes monocrystalline options from various brands. This panel type offers the best efficiency rate and energy production. Monocrystalline panels have become the standard option for most residential solar panel installations. We recommend speaking with a Sunrun representative to get a complete list of available solar panel brands.

Warranty Options

Sunrun’s warranty varies based on your selected financing option. If you purchase your system with cash or a solar loan, your solar panel system includes a 10-year warranty for parts, labor, system repairs, and equipment replacement. You also receive 10 years of roof leak coverage, protecting your home from leaks and damage caused during the installation.

For leasing and power purchase agreement (PPA) customers, the coverage extends to a 25-year warranty, offering the same protections as cash and loan customers with 10-year leak protection. Homeowners also receive additional coverage for solar panel damage and theft.

Installation and Offered Services

Sunrun handles all designing and permitting for its solar systems but employs third-party installers to complete its installations. After installation, customers can use the mySunrun monitoring app to track system performance, gauge average energy usage, and pay bills. Leased customers receive advanced monitoring services, such as proactive service scheduling when system issues are detected.

Along with solar panels, the company offers the Brightbox Home Battery storage option for added backup power. Solar batteries help extend your energy savings by providing additional energy during emergencies or when panels are inoperable.

Homeowners can choose from two top solar batteries: the LG Chem RESU or Tesla Powerwall. The LG Chem can support up to four home circuits, while the Powerwall provides whole-home backup power. Sunrun offers the Ford Connected Charge Station as its EV charger.

Sunrun’s BuilderChoice New Homes Program includes full system installation through its network of home builders nationwide.

These high-efficiency solar panels offer 22% or higher ratings, making them better at converting sunlight into usable electricity.

Sunrun Financing

Sunrun offers four financing options:

SunPower Financing

SunPower also offers the same options for its customers but uses different terminology for some payment options:

Homeowners who use cash payments or loans qualify for additional solar incentive savings, such as the federal solar tax credit. Incentives help lower solar installation costs, helping to make your solar transition more cost-effective. 

During our research, Sunrun emphasized its solar leasing and PPA options more than cash alternatives. The company offers limited information on how leasing options disqualify you from added solar incentive savings. We recommend reviewing all available payment options and selecting the best choice based on your budget and goals.

Sunrun Customer Reviews

Below are several customer reviews for Sunrun:

“I have been up and running for a little longer than 6 months now and am amazed at how efficient my system is. My electric bill has dropped to about $15.00 per month, which is just for small taxes and the electricity delivery charge per month. I am extremely pleased with the system.” —Martin P. via Best Company

“They have been providing us with a great service so far. [T]he system is running properly without any difficulties since they have installed my panels. I have been getting enough energy for my property. I would say that I’m satisfied with the service I have been provided by Sunrun.” —Rustam A. via Best Company

“This company charges a lot more than they are worth. The salespeople didn’t tell the truth about what you would get from the solar panels, and instead of saving money, it has cost me more.” —Mary Z. via Best Company

“My system has been underperforming my contract guarantee for over a year. My customer service rep has changed numerous times and my current one assigned doesn’t respond to emails. All I’ve been told is that they are waiting on parts, for a year now, and they will review my account once it’s fixed. Again, more than a year now. Terrible customer service. Just terrible.” —Wes C. via Best Company

SunPower Customer Reviews

Here’s a sample of recent SunPower reviews:

“I went with SunPower for the knowledgeable presentation I saw and their reputation in the industry. So far, the installation was smooth, and the system seems to be working great. Right in time for our heatwave too!” —Jose F. via Best Company

“I relied heavily on reviews before choosing SunPower. With the exception of a couple scheduling hiccups and failure to notify me they have delivered as promised. The sales representative was very thorough with her explanation and answers, the installation team was very efficient and did a nice job. My system has only been active a few weeks and seems to be doing fine, only time will tell. I am happy with my decision to go with SunPower.”  —William B. via Best Company

“Installation was rough. It required multiple visits the first day and it required multiple scheduling attempts, mostly because the dispatch team would not call and would only text for some weird reason to try to schedule the installation. The technology is awesome, the equipment is great, and it produces power, so it does everything it needs to do, but their project management team and scheduling team is not to the same level as their sales team.”  —Jeme via Best Company

“Overall the experience has been good over the years but in the last year you keep sending out techs who don’t show or don’t fix the issue. I realize they are not part of your organization but neither your group or theirs seems to know what’s going on.” —Sheila K. via Best Company

Our Recommendation

Choosing the right solar energy provider depends on your needs, system preferences, and budget. If you want to invest in high-quality residential panels and the best long-term comprehensive warranty coverage, choose SunPower as your solar company. You’ll benefit from the high-performance system, leading to better energy bill savings. If you’re more interested in leasing your system and not in solar incentives, consider Sunrun for your solar needs. You’ll receive a reliable renewable energy system and added theft or damage protections.

We recommend getting quotes from at least three solar providers to find the best option for your home.
