HQST 100watt solar panel

First Impressions

I have this on the FrontRunner roof rack on the 4Runner.

I have aluminum mounting brackets under this bolted to the roof rack. I’ve been on the highway over 80MPH and had no problems. My vehicle lives outside and so far so good. I have a 10ft cable running inside charging a Jackery 240 battery. I went camping for a weekend and the panel kept enough power in the battery to power a cooler type frig in the back. We had a mix of sun and rain. Mounted flat on the roof is not ideal, but this is what I have. The jackery has a max charge ability of 60 watts. Unless it’s super cloudy, It usually charged at 60. So, this panel is putting out at least that much mounted flat. I now use the jackery to charge other devices like phones and wireless guitar packs etc. All sun power!

Frequently Asked Questions about Solar Panels:

  1. How long does it take for solar panels to start saving me money?
    Experts suggest that homeowners usually experience a return on investment within seven to 12 years after installing solar panels. This is when the savings from reduced energy bills surpass the initial investment. Those opting for leasing or power purchasing agreements may see immediate savings.
  2. Is it more advisable to purchase or lease solar panels?
    If you have the financial means, buying solar panels is preferable, primarily due to the 30% federal tax credit on the total project cost. This credit significantly reduces the overall expense, leading to quicker attainment of “free” energy. Leasing provides energy bill reduction but lacks the tax credits, resulting in comparatively lower long-term savings.
  3. Do you require a permit for solar panel installation?
    The necessity of a permit depends on your location. In many municipalities or within homeowners’ associations, obtaining a permit before initiating the work is likely. Most installers typically handle this permitting process on your behalf.
  4. Care and lifespan of solar panels – Solar panels often come with a 25-year warranty, yet their actual lifespan typically extends beyond this timeframe. Moreover, they boast low maintenance requirements, merely necessitating the removal of obstructions such as dirt, leaves, and snow to ensure optimal performance.

When the sun is out and solar panels’ efficiencies drop, one technology that outputs power to supplement these is wind turbines.
