Installation Quality Is The Most Important Factor

The best solar installers are professional, courteous, and care about your home. These professionals complete a perfect installation and they will leave your property clean.

The best solar installers are not just people who know how to put panels on roofs and work on your service panel. They take pride in their work with clean installations that last a lifetime.

Are The Big National Solar Companies Better?

The advantage of large national solar companies is their financial strength, warranty reserves, and volume pricing. However, the level of service varies greatly. Local installers have a more consistent performance to judge by.

What About Bad Reviews?

How a residential solar installer handles unhappy customers reveals the quality of their customer service. Bad reviews provide good insight into management. 

Are Solar Brokers On The List?

The short answer is no. They are middlemen and aren’t the contractor. Always find out if the company is a licensed contractor or a sales broker by asking for their license number. Check the license on the Contractors State Licensing Board. If they are a broker, then they will only have a Home Improvement Sales License.

Orange County Solar (Southern California)

From The Business:

Orange County Solar Installation specializes in custom solar installations using Premium Solar panels. We offer a variety of premium panels and we are a Panasonic Premium Installer. When it comes to pricing, we’re simply the best. We keep the overhead low so that we can pass the savings on to the customer. This also helps the process to be quick and reliable, allowing you to deal directly with the owner. We also offer premium finance solutions, such as 8, 10, and 12 year 2.99%, and 15 and 20 year 3.99%. 

Why We Like Them:

Premium is the buzzword of choice at OC Solar: Premium panels, financing, customer service, and installation. I like that they start your project with a 3-way QA call between the salesperson, project manager, and customer to be sure everyone is on the same page. This should be mandatory for every solar project! They also end your project with a phone call, which is a nice touch.

After all the research I did, I feel confident that Taylor Energy provided better pricing and a much faster turnaround time than any of the larger companies. In terms of service, all the people at Taylor Energy were helpful, kind, down-to-earth, and definitely knew their business. They worked with us closely to determine the optimal solar panel arrangement and inverter location. They smoothly navigated the permit, inspections, and PG&E details.

We’re here to make your Solar experience a great one. 

Why We Like Them:

We worked for years with SolarQuote’s Operations Manager, and nobody knows solar better than Juan Solano. His installations are perfect! He is a master electrician and a General Contractor, but most of all, he cares about his customers, and it shows. I love that they offer a cleaning and maintenance program because solar panels in California are ridiculously dirty from ash-filled air and gusty winds blowing dirt around, especially since we have very little rain to wash the panels naturally!

Review Highlights:

I worked with Solar Quote on my home installation, and the process couldn’t have been easier. They listened to my wants, designed the system around where I wanted the panels to be while advising me on better placement for better power production. The pricing was very competitive, and the whole process was smooth and without issue. Two years in, my system is working flawlessly, and my summer high bill of $500+ was less than $20 since the installation. I haven’t had to pay anything at true-up either, all around a great system and a great experience dealing with Solar Quote. Highly recommend Solar Quote.
