Green Day Power Overview

Company Background

Green Day Power is a California-based solar company and dealer that has passionately served its residential customers since 2016. They are located in Sacramento, CA, and focus on delivering high-quality solar solutions to homeowners.

Since its inception, the Sacramento solar company has completed over 3,500 projects and has just over 200 employees.

The company mission: “We believe our work keeps the Earth healthy and customers with more energy independence while providing financial freedom from your utility company.”

Service Areas

As of June 2023, the company currently serves Sacramento (NorCal), Fresno, the surrounding Central Valley, Corona, and other areas of Southern California. According to the company website, specific service areas are vague and unclear.

Industry Certifications and Licenses

Though specific industry certifications and licenses were not found in the search results, verifying this information directly with the company when considering their services is essential.

Solar Installation Process

Site Assessment

The site assessment is the first step in the solar installation process. A team of professionals will visit the property to evaluate the potential for solar installation. They will carefully inspect the condition of the roof, its orientation, and any potential shading issues. Furthermore, they will also assess the property’s electrical system to ensure that it is compatible with solar panel installation.

Permits and Approvals

After the initial sales process and site assessment, the necessary permits are obtained before each solar installation. Each jurisdiction has specific requirements, so the company diligently works to obtain these permits and licenses to ensure a seamless and compliant installation process. This phase includes the approval documents and coordinating with utility companies and local and state authorities.

Installing Solar Panels

The next step involves the actual solar panel installation on the roof. Green Day Power’s team of experienced technicians carefully installs the solar panels, ensuring they are securely mounted and positioned to maximize exposure to sunlight. Wiring and other electrical components are also installed during this phase, connecting the panels to the property’s electrical system. The team adheres to safety guidelines and best practices to provide a high-quality, efficient solar installation.

Final Inspection and Activation

Once the solar panels are installed, the system undergoes a final inspection by local authorities or utility representatives to ensure compliance with regulations and safety standards. After a successful review, the solar panel system is activated. The activation includes connecting the system to the grid, allowing the property owner to start generating clean, renewable energy and enjoying the benefits of solar power.

In summary, the solar installation process involves four main steps: site assessment, permits, city inspections and approvals, installing solar panels, and final inspection and activation. The company is committed to providing homeowners in California with a high-quality solar installation experience, prioritizing safety and efficiency while adhering to local regulations.

Costs and Financing

Installation Costs

The California-based solar company offers competitive installation costs for residential solar projects. Although the exact cost of a solar installation varies depending on factors such as system size, location, and equipment choices, the company aims to provide affordable pricing to help more homeowners switch to clean energy. However, based on our research, their average price per watt ranges from $3.30 to $3.65 watt.

Financing Options

To assist with the costs of solar installations, Green Day Power provides a range of financing options for homeowners. These include:

Solar loans: Green Day Power partners with various lenders, allowing customers to find a suitable loan option with competitive interest rates and terms.

Solar financing lenders offered are:

  • Mosaic
  • GoodLeap
  • Dividend Finance
  • Service Finance

Solar leases: For those not interested in owning their solar system outright, solar leases offer an opportunity to install and maintain a system with low monthly payments.

Power Purchase Agreements (PPAs): This option allows customers to install a solar system on their property without any upfront costs. Instead, they agree to purchase solar-generated electricity for a specified term at a fixed rate per kilowatt-hour.

Solar leases and PPAs offered are through Sunrun and Sunnova. In this case, GDP is the solar installer, and the solar companies are the solar agreement fulfillment companies. This is where Green Day Power acts as a dealer while offering its in-house purchase options.


Solar Forever Warranty

When you buy a solar system from Green Day Power’s Forever Solar program, they promise to fix anything that breaks for free, as long as it can be fixed. They offer a 25-Year Full-Service Bumper-to-Bumper warranty that covers parts, panels, and labor. Limited warranties also protect your system from the manufacturers. To learn more, check the details provided by each manufacturer.

Remember to make any warranty claims before the warranty period ends. The 25-Year Solar Forever warranty cannot be transferred, but the manufacturer’s warranty can be transferred within the first ten years for free. After ten years, there’s a fee of $100 per remaining warranty year.

This warranty covers various components and installations provided by Green Day Power. These include solar panels, brackets, inverters, wiring, foundations, and interconnection equipment. It also covers leaks caused by roof penetrations made during installation, excluding leaks that would have happened without them. Green Day Power’s liability for roof penetration won’t exceed the total purchase price of the solar system.

Besides the mentioned warranty, Green Day Power doesn’t provide any other warranties, including implied warranties of quality and performance. This warranty doesn’t cover damage resulting from improper use or maintenance, unauthorized repairs or installations, abuse, negligence, natural disasters, or repairs/maintenance done by others. No implied or statutory warranties of merchantability or fitness for a specific purpose will apply.

You’ll receive any warranties the component manufacturers provide, such as solar panels, inverters, and disconnect switches. If a specific component is unavailable, Green Day Power can substitute it with a reasonable equivalent item.

Incentives and Rebates

Green Day Power customers may benefit from various federal, state, and local solar incentives, rebates, and financing options. Some examples include:

  • Federal Investment Tax Credit (ITC): The federal tax credit allows homeowners to claim a percentage of their solar installation costs on their federal income taxes, potentially reducing overall costs.
  • State and local incentives: Various states and municipalities offer additional solar incentives such as tax credits, rebates, or property tax exemptions to encourage the adoption of solar energy.
  • Utility rebates: Some utility companies may offer refunds for solar installations, reducing overall costs.

To maximize their savings, Green Day Power will work with customers to help identify and apply for all the available incentives and rebates applicable to their specific situation.

Customer Experience

Customer Reviews

Mixed reviews are expected with most solar companies, Green Day Power is no different. Some clients have rated the company highly, giving them 5 stars. On the other hand, some customers have given them ratings as low as 1 star. The differences in these ratings could be due to individual project experiences, expectations, or even customer service during the solar installation process.

Customer Service

Customer service is essential to any business, and Green Day Power receives both positive and negative feedback. Some customers report having had a smooth experience working with the company, while others have faced challenges and felt frustrated dealing with them. The different experiences shared by customers imply that the company might have inconsistencies in service quality which should be addressed to maintain a good reputation.


Effective communication between a company and its customers is vital for a successful project. Green Day Power has been facing communication issues with its clients, as seen in some reviews. While some customers have appreciated their responsiveness and transparent communication, others have been displeased with their experiences, citing delays and unresponsiveness. Improving company and client communication can help enhance customer satisfaction and foster better relationships.
