Solar Panels and Services offered by Slingshot Power

Specific Solar Panels Offered

Slingshot Power installs solar panels from the following solar manufacturers;

  • Q CELLS: Q-Cells is a South Korean solar manufacturer that develops and sells photovoltaic (PV) solar cells. Q CELLS solar panels start at around 20% efficiency with the Q.PEAK DUO-G5, and top out at 20.9% with the Q.PEAK DUO XL-G9. The panels come in different models ranging in output power of 345 to 500 watts.

The SunPower M-Series AC solar panels are the highest-efficiency available at 440-420 watts. The X-Series delivers more power and savings, with fewer panels on your roof.

Installation costs and process


The cost of going solar with Slingshot Power is estimated to be about $3.00 per watt before any solar incentive. There are several solar incentives available that could cut these costs to very affordable levels. Incentives such as;

  • Federal Solar Tax Credit (ITC): With this solar incentive, every solar patronizer in the US is eligible to a 26% tax credit for solar systems installed in the years 2020 to 2022, then it comes down to 22% in 2023. This means you can reduce the total cost of installing a solar system for your home or business by 26%. But remember this incentive applies to those who buy their system either by cash purchase or solar loan, and not leases.
  • Net Metering Program: Electric utilities in California offer “true net metering” to customers with solar PV systems.


Some of the solar incentives available in California include;

  • California Solar System Property Tax Exemption: California has a renewable energy property tax exemption so that residents of the State don’t pay extra taxes as a result of the value their solar panels add to their homes


Slingshot Power offers the following financing options;

  • Loan – You can apply for a loan through your local bank or credit union or explore Slingshot Power’ loan options, allowing you to finance your solar system even if you cannot purchase it outright. Clients can also utilize tax credits and rebates for a cheaper payment.
  • Lease – Low monthly payments to add solar to your home or business.
  • PACE – Through the Property Assessed Clean Energy (PACE) program, businesses in participating areas can pay for their solar system through their property tax, allowing repayment for up to 20 years on a fixed rate loan.


Based on our analysis of their competitors in the state, we expect Slingshot Power’s price rates to meet the average standard solar rates in California. Any reader interested in going solar in California should also take advantage of the solar incentives available in the state.
