Green Power Energy Solar Installation Options

Green Power offers solar panel installation to a variety of homeowners, businesses, and farmers in the Northeast.

Residential Solar Installation

Green Power residential installation follows a structured six-step process to guide homeowners through the entire project.

  1. Conversation: After filling out an online quote form, you will be contacted by Green Power to discuss your energy needs and walk through the home evaluation process. At this time, Green Power will schedule an appointment for a more in-depth conversation about what you’re looking for in a solar system.
  2. Survey: During your scheduled, in-person appointment, Green Power technicians will survey your property and discuss your best option for a home solar system.
  3. Design walkthrough: After your home consultation, Green Power Energy will design a custom system for your home and send it off for your approval, free of charge.
  4. Solar education: Before installation, Green Power will answer any questions you have and talk with you about what to expect from your upcoming solar panel construction.
  5. Installation: Green Power Energy will obtain proper permitting before the installation process begins. During installation, an on-site project manager will oversee the operation and be on-call for any questions or concerns that arise. Installation is typically completed within three days.
  6. Walk-through: When system installation is complete, the Green Power team will walk you through how to operate your system.

Note: For customers who want to save the excess energy their system generates for future use, Green Power offers a Tesla Powerwall for solar battery storage. The initial cost of a Tesla Powerwall battery starts around $9,000 without installation.

Commercial Solar Installation

Green Power Solar provides system installation to help businesses achieve energy independence and reduce their electric bills. On its website, Green Power explains the benefits available to businesses when they choose to go solar, including:

  • A federal government tax incentive worth 30% of the cost of the system
  • Solar Renewable Energy Certificates (SRECs) available to sell on the open market
  • Increased property value
  • The Modified Accelerated Cost Recovery System (MACRS) that results in a tax deduction

Pro Tip

  • As solar installer Christina explained during a This Old House project featuring over 60 panels: “The microinverters are great because you aren’t relying on the entire group. They work as individuals instead. So if you have a damaged panel or it’s shaded at a certain point in the day, the other panels will operate as usual.” Businesses considering commercial solar should ask their installer about microinverter technology, which can maximize energy production across large rooftop arrays.

Agricultural Solar Installation

Green Power Energy also offers solar installation to farm and landowners. The company works around your schedule to ensure it doesn’t interrupt the agricultural or livestock farming process. Similar to on-site screening during the residential installation process, Green Power analyzes your barn’s roof structure to ensure it can withstand a solar system. The company also caters to your unique energy needs to establish a construction plan that is minimally invasive and effective.

Pro Tip

  • When evaluating a barn roof for solar, installers on a This Old House project explained that they look for three key factors: the roof should face solar south (within about 15 degrees), the pitch should be between 30 and 45 degrees to optimize sun exposure and allow snow to shed in winter, and there should be minimal obstructions like trees that could cast shade on the panels—since shade is one of the biggest enemies of solar production.

Cost of a Green Energy Systems Solar Installation

The cost of solar installation by Green Power Energy depends on numerous factors, however, the average cost falls between $20,000 and $30,000. Green Power Energy offers potential customers a snapshot of their 20-year savings outcome through its online calculator. To give you an idea of your potential financial returns with solar energy from Green Power, we received a savings estimate based on a monthly electric bill of $110.

Green Power Energy Solar Savings Estimate

  • Monthly Electric Bill: $110
  • 20-Year Savings Estimate: $37,325

Pro Tip

  • Kevin Price, a solar installer featured on This Old House, explains why solar costs have become more competitive: “It is now cheaper to make electricity from the sun than the utility can make from the big power plant.” He attributes this to three key factors: the free cost of fuel from the sun, government incentives, and the dramatic drop in equipment prices.

Payment Options

Green Power provides customers with four purchasing options for solar panels and battery back-up installation: purchase, loan, lease, and power purchase agreement (PPA).

  1. Purchase: Customers can purchase their system upfront to experience immediate returns on their investment, as no monthly payment is required.
  2. Solar loan: Solar loan customers can own their system through set monthly payments starting at $0 down.
  3. Solar lease: Customers who lease their system pay set monthly payments over a fixed period to use their solar system.
  4. PPA: Customers who sign a PPA pay monthly for the power their solar panels generate.

Pro Tip

  • With lease and PPA options, it’s important to read the fine print carefully. As experts on Ask This Old House have cautioned, these are contracts with specific terms that homeowners need to understand—particularly what happens at the end of the lease or power purchase agreement. With the purchase and loan options, there’s no end date to worry about because you own the system outright, but lease and PPA contracts require careful review of their expiration terms.

How Does Green Power Energy Compare to Competitors?

While Green Power Energy offers a solid option within its three-state service area, we suggest homeowners compare services and rates offered by at least three companies before deciding on an installer. Learn more about some of our top-rated solar companies below.

Is Green Power Energy a Good Choice?

Green Power Energy is a good choice for going solar, based on our review. The company has installed nearly 150,000 solar panel systems across its service area of Texas, Connecticut, and New Jersey, and has an in-house team of North American Board of Certified Energy Practitioners (NABCEP)-certified technicians for high-quality installation. The installer also offers electric vehicle (EV) charging as well as repair services for existing systems. 

Add these services to the company’s flexible financing options and higher-than-average customer reviews, and we found that Green Power Energy is an installer worth considering for your solar project.

Pro Tip

  • As discussed on Ask This Old House, purchasing your system outright is the best financial option because all the tax credits, renewable energy credits, rebates, and electricity savings go directly to you. A solar loan is the next best choice—similar to a home equity loan for a kitchen renovation, you still own the asset and receive all the financial benefits while paying it back over time.

FAQs about Green Power Energy

Does my roof need to face a certain direction for me to go solar?

Although the ideal roof orientation is facing south, solar installers can work with a variety of roof orientations and slopes. Green Power Energy’s solar consultants will evaluate your roof to ensure it can support an efficient solar system before installation.

Can I install my solar system myself?

We recommend getting your solar system installed by a professional because of the expertise required to complete the project.

Do solar panels make noise?

Solar panels aren’t supposed to make any sound when absorbing sunlight and converting it into solar power, though you may experience wind noise because of your roof’s shape or panel installation.
