How Much Does PosiGen Cost?

While PosiGen does not publish pricing, the average monthly cost for a solar lease is $50 to $200. A number of factors will affect a homeowner’s monthly cost, including the size of the system, a household’s energy needs, solar storage options, panel manufacturer, and local labor rates. For homeowners who desire to purchase their solar panels, the average installation cost is $16,500 for a 1,500 square foot home.

PosiGen is primarily a solar leasing company; however, it also offers direct purchase and financing options. Specific pricing and loan details are only available through an appointment with a company representative, however Modernize home improvement experts indicate the average cost for solar panel installation is $12,000 to $30,000 after federal tax credits.

Posigen Review: Factors Affecting Costs

Solar panel installation costs vary because each home and household is different. Even so, there are factors that influence solar installation purchase, financing, and leasing costs. Here are the primary things to consider when evaluating PosiGen:

  • System Size: How much energy a household needs determines the size of its solar panel system. PosiGen will evaluate a home’s electric bill to determine its solar requirements. If solar panels are intended to provide complete grid independence, that will also increase the cost.
  • Roof Type: Some roofs are easier for solar installation than others. Steep roofs and those needing additional repairs prior to installation require more equipment and labor.
  • Solar Panel Type: Several types of solar panels are available for residential applications. On average, monocrystalline solar panels are the most energy-efficient and cost-effective for homeowners. Solar tiles blend with roof shingles but typically come with a higher price tag. High-efficiency brands and panels are often more expensive due to their higher energy conversion and output.
  • Leasing vs. Financing: Solar leasing offers initial savings with no down payments or upfront costs, however it is often more expensive in the long term compared to paying cash or financing.
  • Local Labor Rates: PosiGen employs in-house and independent contractors for its solar installations, depending on the region. Labor rates can vary widely from state to state and will impact installation or monthly leasing costs.

Benefits of Investing in PosiGen

PosiGen allows homeowners to enjoy cost savings and increased energy independence from solar panels without the large upfront costs associated with direct purchase or financing. As owners of the leased system, PosiGen also takes care of the design, installation, insurance, and regular maintenance for many years of worry-free service.
