My new panels look great and are performing well. The whole team at OnSite was great to work with, from the installers to the sales crew. I've worked with them on two projects now, and I know they take care of their customers, with one of the projects requiring some warranty work that was taken care of quickly. My only minor complaint was that they were slammed when I contacted them (Late March 2020), and it took until the end of September before my panels were turned on. Overall I'd absolutely work with them again, though!

OnSite Energy was recommended by a neighbor and we were not disappointed. We installed a solar powered battery backup system with net metering. Throughout, communications with company were clear, project design was tailored to our needs, timelines were realistic, and the cost estimates were all-inclusive. The installation team was friendly and efficient. We received a detailed tutorial on the use of our system and the office team responded quickly to any queries. We have no hesitation recommending this company.

Follow up was done on system to make sure everything was operating. Would recommend them highly.

We purchased a house that had a system previously installed by OnSite Energy. We contacted them to see what it would take to increase the size of the system. From this first contact onward they were professional and easy to work with. We decided to go ahead with the project and the installation went smoothly. On our request, they quoted the job using a previously installed (not by them) wind generator inverter. At the completion of the installation, the existing inverter was unable to support the system properly. OnSite worked with us to fix the issue despite it not being their problem. We're very happy with the outcome, their service and would not hesitate in recommending them.

We love our new solar system. This was all new to us, but Conor spent as much time as necessary to help us understand the system and the financing/incentives. Sam handled the installation professionally and with very open communication. We loved the entire process and really enjoy using the app to watch our solar system work. We highly recommend OnSite Energy.

We had a good plan for our solar needs and placement. Conor and the Onsite Team were great to work with. Everything from counsel over components, system design and installation, and follow up after we went online with NWE. System is working great and producing more power than anticipated.

Happy Customer in Montana | Bozeman, Montana

We highly recommend Onsite Energy if you are considering installing a solar energy system. When we contacted Onsite Energy, one of their associates came to our property within a few days to evaluate our house for potential solar panel installation. We received a quote within a day of his visit. The quote was thorough, easy to follow and understand, and provided several options for payment. Once we decided to undertake the project, we were given a timeline. Onsite Energy held to the date they provided and met all the benchmarks they committed to. Their management team was helpful, detail oriented, and prompt at getting back to us with any questions we had. Their install team was friendly, professional, neat, and careful. We think they took safety very seriously. We are very happy with the product and will recommend Onsite Energy to any potential customers as they were recommended to us by former customer.

Swanson Family | Bozeman, Montana

When we built our new home we knew that we wanted a solar component to be part of the overall project. We wisely chose the services of Onsite Energy to craft and install our solar array. Every member of the company with whom we interacted was not only professional but highly personable. The mix of great folks plus superior products make for our strong recommendation of Onsite Energy being your solar service provider.

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 OnSite Energy consider:

Experience and Reputation:

Look for a company with a solid track record and years of experience in the solar industry. Read the latest OnSite Energy 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 OnSite Energy.

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

  • Qualification: Contact solar companies through web forms, referrals, or flyers. Answer questions to determine eligibility.
  • System Design: Receive initial solar system design in a proposal. Review the design and consider panel placement, avoiding “under-sizing“ or “oversizing.“
  • Compare Quotes: Evaluate quotes, considering factors like monthly payments, power output, and system details. Seek guidance to simplify the comparison.
  • Contract Signing: Select a company and panel design, understand and sign the contract.
  • 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.
  • Permitting: The company obtains necessary permits and approvals, ensuring compliance with regulations.
  • 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.
