From start to finish, Cosmic Solar made the entire installation easy! It took just a few months from start to finish! They helped us source financing.

What a great solar company! Starting with the Senior Energy Consultant / Ken very professional, on time and walked the talk. Roofing Manager / Ron also was very professional and helpful coming up with a solution for a part of my re-roof project. Office Staff / Mary and Arlene outstanding customer service and very attentive. Being in the construction trades myself for over 40 years I've work with many tradesmen and I have to say that both the roofers and solar system crews were top notch, left the site clean each day and installed all products in a professional manner. I would / and have recommended Cosmic Solar and Roofing to many of family members and friends. Thanks for an outstanding install and experience . Scott F.

My wife and I recently had a main service panel upgrade and residential solar system installed by Cosmic Solar and their electrician Joel Johnson (interconnection/completed date 8/9/2022). After extensive research on solar, we debated on using a national/regional installer vs a local installer but ultimately decided we preferred supporting a local company, having the whole process be in house with one company, and felt customer service would be superior. Cosmic Solar's customer service, installation, products, and performance are prime evidence of this. Pey, Arlene, Alison, and Mary were a pleasure to work with from the beginning - they outlined the process at the start clearly and stayed in constant communication along the way to ensure everything was moving along appropriately. Pey and the entire office staff always seemed to be one step ahead with the solar paperwork flow and all the necessary documents and permits - by the end, there was not a single delay with SDGE or the city and the project was ultimately approved and completed ahead of schedule. Just as important for this to happen was the efficient installation process Cosmic delivers. Hector and Alex were our solar installers and they did a great job - they were noticeably efficient while performing quality work, very personable and approachable, and took care of our roof and the surrounding areas of our house. They were also able to find a way to run all the conduit safely through our attic to the service panel thus concealing it and avoiding conduit running along the side of our house. A few days later on a day pre-scheduled with SDGE, Joel Johnson came to perform the main service panel upgrade. He was also a pleasure to have on the job - very efficient (power was only off for a few hours) and performed expert level electrical work throughout the whole process. His stucco and painting work was superb as well - the new panel and the surrounding area looked better than it was before. My wife and I plan to use Joel Johnson for any future electrical work we need done in our house. Following this, Cesar and Johnny came out a few days later for the city inspection and to finish up final details (final wiring, SunPower monitor placement, etc.). Again, as expected, everything was done in a timely, efficient, and friendly manner. And on top of all this, the SunPower products that Cosmic uses are top of the line and offer the highest performance and efficiency you can obtain on the market. They also offer a competitive price for these products. Given our installation experience and their track record, we also know Cosmic Solar will offer us a top level service experience for any service we may need along the way led by their Service Manager Khiry. When you put this all together, we plan to recommend Cosmic Solar to anyone who reaches out for a referral and encourage anyone reading this review to use Cosmic Solar for your solar installation needs.

Cosmic Solar was referred by a friend and we couldn't be happier. The install crew went above and beyond...on time and friendly! Can't wait to start saving on our electric bill.

Cosmic Solar installed our solar panels in 2019 and since then we have been able to utilize our heater and air without paying huge amounts of money on our SDG&E bill. In fact, we usually get a credit each month. We were impressed with the installation and follow up of this company. I highly recommend them and will contact them for any future solar needs!

We needed new roof before we could install solar panels. Their roofing work was excellent and Ron Schwenk was especially knowledgeable in fitting our roof needs. Cosmic Solar was an excellent choice for us because we wanted battery backup.

Cosmic solar had the most honest and transparent sales process of all the companies I spoke with (Ken is great). They installed my panels quickly and everything looks/works great. We are very happy with our system!

What To Look For In A Solar Installer?

When looking for a solar installer, it's essential to consider various factors to ensure you choose a reputable and competent company that meets your needs.

When selecting an installer like Cosmic Solar, Inc. consider:

Experience and Reputation:

Look for a company with a solid track record and years of experience in the solar industry. Read the latest Cosmic Solar, Inc. solar reviews from past customers to gauge their reputation.

Certifications and Licenses:

Ensure the installer holds the necessary licenses and certifications required in your area. Look for certifications from organizations like the North American Board of Certified Energy Practitioners (NABCEP) to verify their expertise.

Quality Products and Technology:

Inquire about the types and brands of solar panels, inverters, and other equipment they use. Quality matters for long-term performance. Ask if they offer the latest solar technologies, such as high-efficiency panels or energy storage solutions.

Warranty Information:

Understand the warranties they offer for equipment and workmanship. A reputable installer should provide comprehensive warranties. The majority of modern solar panels are equipped with a warranty spanning 20 to 30 years, encompassing both the product's integrity and its energy output. An ordinary workmanship warranty offered by a certified company typically provides coverage for solar panels for an average period of 10 years.

Transparent Pricing and Contracts:

Get detailed solar quotes that include all costs, from equipment and labor to permits and inspections. Review the contract carefully to ensure it's clear and transparent, with no hidden fees or surprises.

Local Knowledge:

Choose a company familiar with local building codes, regulations, and permitting processes. This can expedite the installation and ensure compliance.

Customized Design:

Look for companies who provide custom solar system designs tailored to your specific energy needs and property characteristics.

Energy Production Estimates:

The installer should provide accurate estimates of how much energy the system will generate, factoring in local climate conditions and other key influences. If your estimated solar savings are much higher with one solar company, you'll want to inquire further to ensure their savings projections aren't skewed to close the sale. Connect with us for a free estimate.

Financing Options:

Inquire about solar financing options, including purchase, lease, or power purchase agreements (PPAs). Ensure you know the pros and cons of each option.

Customer Service:

Assess their responsiveness and willingness to answer your questions and concerns and consider the installer's commitment to your project satisfaction. Throughout your solar process we’ll advocate for you, ensuring your solar project is done right.

References and Recommendations:

Seek recommendations from friends, family, or colleagues who have installed solar panels. Ask the installer for references from past clients who can share their experiences. You can also read the latest reviews on Cosmic Solar, Inc..

Multiple Quotes:

Don't hesitate to obtain quotes from multiple installers to compare pricing, services, and warranties. Hint: We can help!

Financing and Incentive Knowledge:

Ensure the installer is knowledgeable about available incentives, tax credits, rebates and financing options. At EnergyPal, we’ll help maximize your savings.

Safety Practices:

Confirm that the installer adheres to safety protocols during installation to protect both workers and your property.
