How To Become A Solar Installer: 6 Tips Plus Mistakes To Avoid

The solar energy industry is growing by leaps and bounds. Due to exceptional opportunities, many new solar installers are entering the market.

As with most things, there is a learning curve involved with the solar installation process. However, applying these tips can help keep projects on schedule and on budget. In addition, avoiding certain pitfalls can increase your sales and boost your reputation. Let’s examine these so you can avoid common mistakes when starting out in the solar energy business.

Top Tips For New Solar Installers

There are many tricks of the trade that are critical to prosper as a solar provider. And, solar panel systems vary by the property and installation process. Here are our top tips for new installers.

Get Familiar With Solar Panel Terminology

It is critical to be able to explain solar panel technology to potential clients and answer all their questions articulately. Likewise, being able to read and understand solar panel installation manuals and spec sheets is essential for proper solar system design and installation. Also, it could be difficult to obtain permits without basic solar panel terminology in your vocabulary.

A handful of essential vocabulary includes:

A great way to get familiar with essential terms is to read articles, specification sheets, and manuals. The GreenLancer blog is a great place to get started!

Learn PV Battery Terminology

Solar batteries have skyrocketed in popularity as many homeowners want to gain energy independence and avoid disruption from power outages. However, just like solar panels, it is essential to develop a vocabulary around batteries. Make sure to read up on storage options for solar installations.

Sharpen Your Skills

It is critical to gain the skillset required to both attract customers and then safely design and install solar energy systems. If one person is fulfilling all of these roles, it can require learning a bit of everything.

  • Hands-on experience: Although reading on the topic is a great way to learn, nothing beats hands-on experience. If possible, attend a local workshop or hands-on training program. In some cases, it might be possible to volunteer with a non-profit. Many solar installers work for other companies before starting their own firms.

  • Customer service: Providing excellent customer service is critical for building a positive reputation and gaining referrals. This involves responding promptly to phone calls and emails, keeping projects on schedule, communicating issues clearly with customers, and performing high-quality work.

  • Safety protocols: Ensuring a safe worksite is essential. Falls are among the most concerning issues on solar job sites because many systems are installed on roofs. Therefore, it is essential to follow OSHA standards and use fall prevention measures.

  • Sales: If you can’t make sales, running a profitable solar installation company will be nearly impossible. This starts with having effective lead generation strategies and definitely includes closing sales. Having an attractive website and marketing materials can assist in this. You can seek out 3rd parties who specialize in sales and marketing to potential solar clients to supercharge your efforts.

Make Sure You Have The Necessary Solar Installer Certifications

Although they vary widely across the U.S., some states have specific licensing requirements for solar installers. For example, a C-46 license is required in California, while other states require a licensed electrician to complete solar PV installations. Therefore, before launching your solar installation company, it is critical to know the qualifications in your state.

Having the appropriate licenses, certifications, and insurances can help earn trust among solar shoppers. So let’s explore some of the top certifications in the solar industry.

  • North American Board of Certified Energy Practitioners (NABCEP) Certification: This program for renewable energy professionals involves passing an exam and having the minimum required hours in the field.

  • OHSA Construction Safety: These courses are designed to prevent injury on the job. The OSHA 10-Hour for the Construction Industry course is a good choice for solar installers. In addition, many OSHA courses are available online, eliminating the need to travel.

  • Electrical license: These licenses are issued on a state-wide level, and the requirements vary by state. Typically, there are different levels of licensed electricians, and they require passing an exam and possibly completing a certain number of hours in the field.

Understand State And Local Regulations and Incentives

From permitting requirements to local incentives and rebates, the solar energy industry varies by state and local governments. Before opening your business, it is essential to know the regulations and perks in your area. If there are additional incentives beyond the federal tax credit, let solar shoppers know and put this information on your proposals and feasibility studies. The DSIRE database is a great way to learn about local incentives.

Likewise, many states have additional siting requirements, such as setbacks. Even local building codes vary by location, especially if an area is prone to hurricanes or extreme weather. GreenLancer has the expertise to design and engineer systems that comply with the local utility and building department’s codes and requirements.

Understand Solar Warranties

The vast majority of the solar equipment you install will include warranties that vary by the manufacturer. For example, solar panels come with power performance guarantees and product warranties that commonly last ten years and often much longer. Inverter warranties usually last at very least five years. Lithium-ion solar battery warranties typically last around ten years. Likewise, racking systems often have warranties ranging from 10 – 25 years.

It's important that installers understand this information so they can effectively communicate it to clients. In fact, these warranties help protect client solar investments and might be required for solar financing. Keep in mind that the warranties are often for the product but don’t necessarily pay for the labor to swap out a failed piece of equipment. Many installers list warranty information on their solar proposals to make it crystal clear to potential customers.

Common Mistakes To Avoid

Unfortunately, there are also some common pitfalls to avoid when launching a solar business. Avoiding these issues can help with client acquisition and boost sales.

Not Educating The Client

Unless they demonstrate otherwise, don’t assume your potential clients know much about solar panels or solar power in general. Educate them on the benefits of solar energy and dispel common myths to close a sale. This is especially true for commonly misunderstood aspects of solar, like power purchase agreements (PPAs).

Therefore, use your proposals, website, and even additional educational materials like videos, infographics, blogs, and social media posts to educate your customers about solar energy as a home improvement. In addition, many solar installers include estimated utility bill savings, the payback period, and tax credit information on the contracts. Finally, after installing the solar modules, make sure your customers understand how to read their electricity bills, especially in areas with net metering.

Often, solar design software is an excellent tool to assist in educating your clients. For example, some programs will create a mockup of the solar PV system on the home, perform a shading analysis, and calculate estimated solar savings. In addition, the PVWatts calculator is an excellent resource for evaluating solar power system output and utility company savings based on the system size and potential shading.

Not Asking For Referrals

Some of your best leads will come from existing customers, especially if you ask for referrals. Often, you will have already earned the trust of referral clients, and they may even have seen one of your projects. This is because your existing customers will help educate new potential customers. As a result, referrals have higher closing rates than other channels for leads and often save time in the sales process. In addition, some solar companies offer a referral bonus to existing customers to encourage referrals.


Establishing a solar business does require learning some new skills. Often, this expertise is quite varied and includes everything from roof safety practices to permitting requirements. While it might sound like a lot to handle, understanding the common mistakes and how to avoid them will set you up for long term success in the solar business.
