So, how do I rate a contractor? (1) Communication. From telling me what's being done to why to when it's being done, I want someone who will communicate with me. I have NEVER worked with a company more communicative than A1 Sun. I knew when they were coming, what they were doing, how long they were going to be there, and so forth. If I had a question, I emailed them and had a response within HOURS, not days. They were truly an amazing group to work with. (2) Quality of work. I work from home, so I get to watch the work from start to finish and yes, I pay attention. They did excellent work throughout. (3) Quality of workers. The people who came to work on my house were uniformly wonderful, up to and including knocking on my door to suggest that I bring my "little ones" (cats) inside just in case anything fell off the roof (nothing ever did). They were conscientious. They were friendly. I honestly enjoyed having them around. How often can you say that about the workers at your house? (4) Clarity of the bill. I got an itemized bill before the project started. I was warned of one cost overrun because of dry rot in my roof. I paid EXACTLY the estimated amount, plus EXACTLY the overrun estimate. Nothing like knowing exactly what you're paying. (5) Ease. They showed up. They did everything. They even handled the PG&E paperwork. I signed one e-Document and now I have solar power. Couldn't have been easier! In short, they were fast, they were friendly, they told me exactly how much it would be up front, and they did quality work. I cannot imagine hiring any other solar company after having worked with them. (Yes, I'm copy-pasting my review from Yelp. I liked them so much I'm hitting a bunch of sites)

Our experience with A1 Sun has been stellar. After researching all the local solar company options, we were so grateful to have found and settled on the best. We had our panels installed three years ago and they have been generating and making us smile at our PG & E bills ever since. A1 Sun truly cares about each and every customer and is committed to making it as easy as possible for you. They, not you, do all the hard work, including the permits, paperwork and installation and followup. It was a great pleasure working with Larry, Kathleen and the rest of their crew. Thanks again A-1 Sun!

This Oakland/Berkeley based solar company is absolutely first rate. From the time of the first meeting (estimate) to the completion of the job I had no problems. Everything was done professionally and the workers were on time and worked hard until the job was completed. All of my questions were answered completely and quickly. I really did not need to do anything including the potential hassle of dealing with PG & E to get hooked up to the Grid. I think for anyone interested in installing Solar, AI Sun could not be a better choice.

System installed Dec 2012. No options on tilt of panel, but they did raise them to reduce shading from nearby building. No problems with the installation, which was quick. Panels were U.S. made per customer request (Sunpower). System uses Enphase inverters. Installation on a second house 2014. They came out to make a bid, and noticed roof was about to be installed. They installed standoffs that day without a contract (saving us some money). We accepted their bid, and again the installation was done promptly without problems. Very pleasant to work with.

I was skeptical about installing a solar energy unit. Had bad experiences with two large companies. Found a smaller, local company in A1 Sun. They are a pleasure to deal with and and provide good value. I could not be happier with the service and product they provided.

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 A1 Sun 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 A1 Sun 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 A1 Sun 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.

By researching and considering these factors, you can select a reputable solar installer who will provide a quality solar energy system and a positive experience throughout the installation process. Connect with us to learn more about the best solar installers in your area.

Assess warranties, support, and the installer's experience while also checking for customer feedback and references. Gauge their responsiveness and customer service, ensuring they educate you about the process. Consider an installer's licensing, and certifications. Request accurate energy production estimates and review contracts for transparency. By evaluating these factors, you can confidently choose the solar installation option that aligns with your energy goals and budget. Connect with us for a free quote.

Steps for Installing Solar Panels

  • Site Survey: Technician assesses the site for solar panel installation, checking roof orientation and structural integrity.
  • Engineering: Behind-the-scenes process finalizes system layout, electrical configuration, and structural safety for permit submission.

  • Installation: Expert team mounts panels, installs wiring and inverters, connects the system to the grid.
  • System Activation: Request final inspections, obtain permission to operate (PTO) from the utility, and turn on the system. Monitoring apps track power generation.
