Review by in Vallejo, CA
Carsten did an excellent job installing our solar panels! He made the entire process seamless and easy, from initiating the PG&E application and obtaining the city permit, to installation and finally connecting to the grid. I was a little nervous about working with such a new company, but have no regrets choosing Gomaxxx now that the process is complete. We also received a quote from a large solar panel company, but Carsten charged a much fairer price and we wanted to support a local business. We met with Carsten a couple of times before signing the contract to review the design plans and ask him questions. He was very professional, knowledgeable, and provided thorough explanations. He was patient with answering our questions and promptly responded to all follow-up emails. We requested that the installation be completed before the end of the year. When we found out that the panels in our original design plan wouldn't be available until early next year, Carsten selected a different brand of panels, which I think were even better and would be available immediately. The installation took a little more time than expected, but Carsten kept us informed throughout and he took his time to ensure everything was properly done. We are very pleased with the quality of the materials and workmanship. When we received final approval from the city inspector and PG&E (which happened only one day after installation was complete!), Carsten turned our system on and even did some trouble-shooting to connect our inverter to wifi so we could monitor our production in real time. It's been about one week since our system has been in operation and we are very happy with our production so far! While everything happened very quickly, we never felt rushed, and Carsten was great to work with throughout the process. He provided detailed and well-prepared documentation of the design and wiring, as well as all of the equipment manuals. I wouldn't hesitate to work with Carsten again and highly recommend Gomaxxx to anyone interested in going solar.
Response by GOMAXXX, Inc.: Thanks Charlene for the nice review. It was my pleasure to install that system for you, which works great and is producing as predicted.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
