In addition to electronics, furniture, appliances, and groceries, Costco members also have access to solar products. Here are four important things to know before deciding whether or not to purchase solar though Costco:

1. Costco members have access to DIY solar kits as well as residential solar systems from Sunrun

There are two very different ways to go solar through Costco.

The first is by purchasing solar equipment from Costco and installing it on your own. Costco sells Grape Solar 5830 Watt Grid-Tied solar kits, which include 22 solar panels, an inverter, and a roof mounting system. The retailer also sells Goal Zero Nomad 100 solar panels and Goal Zero Yeti 1000 + Nomad 100 solar generator kits that customers may use in their solar outfits. However, do-it-yourself solar installation isn’t the best option for everyone.

The second solar option for Costco customers is a residential solar system from one of the nation’s largest solar providers, Sunrun. With this option, Sunrun will provide customers with high quality solar equipment, professional installation, warranties, and system monitoring.

2. Customers can earn a 10% Costco Shop Card on qualifying residential solar system purchases

Costco members who purchase a qualifying residential solar system from Sunrun, either with cash or with a loan (not through a lease or a power purchase agreement), will receive a Costco Shop Card for 10% of the pre-tax cost of the equipment, including solar panels, racking, inverters, and batteries. This promotion does not apply to the cost of the installation.

These Costco Shop Cards may be used toward merchandise at Costco, including purchases at the Costco Gas Station and Costco Food Court.

3. Individuals who purchase a residential solar system from Sunrun through Costco will receive an extended roof penetration warranty

Sunrun provides all customers with a number of warranties, including a 20-year warranty on workmanship and a 10-year warranty on roof penetration. However, customers who purchase a Sunrun solar system through Costco will receive an extra 5 years added on to the roof penetration warranty, bringing roof coverage up to a total of 15 years.

4. Residential solar system purchases through Costco are only available in select states

Only individuals who live in select areas have access to a Sunrun solar system through Costco. Available areas include the following:

  • Arizona
  • California
  • Colorado
  • Connecticut
  • Florida
  • Hawaii
  • Illinois
  • Massachusetts
  • New Jersey
  • New Mexico
  • New York
  • Nevada
  • South Carolina
  • Texas
  • Vermont

If you live in one of these areas, a Sunrun solar system through Costco may worth looking into, but we always recommend obtaining multiple solar quotes and price shopping before making a decision. Whether or not you live in one of the states listed above, you can view top rated solar companies in your area and read solar company reviews here.
