The Highest Quality Solar Panels

Our passion for quality and performance begins with installing the best solar panels from a trusted and experienced manufacturer. That’s why we partner with SolarWorld, the largest US manufacturer of solar panels since 1975, to ensure our solar panels meet and exceed the highest performance specifications and quality standards. All of our solar panels come with a 25 year warranty and are manufactured in Hillsboro, Oregon.

Powerful & Beautiful

Can’t solar panels be both powerful and aesthetically attractive? With Kasselman Solar, the answer is yes. We install SolarWorld monocrystalline black solar panels to give our customers the best looking and most powerful solar panels available. Aside from being black, these solar panels are also thin (just 1.2 inches thick), allowing for an elegant design that blends with the roof line and provides a sleek, low-profile appearance.


Key Features:

  • High-efficiency monocrystalline cells.
  • 25-year linear performance guarantee.
  • All black appearance creates sleek & low-profile roof installations.
  • SolarWorld Energy Conversion & Light Capture Technology.
  • Manufacturing solar panels in the US since 1975.
  • Anti-reflective coating minimizes glare & maximizes solar yield.

Each solar panel we install is was made in Hillsboro, Oregon by US workers. SolarWorld’s US factory is evidence of their superior solar panel manufacturing process by skilled US workers. Manufacturing solar panels since 1975, SolarWorld has demonstrated a commitment to longevity and solid financial footing, assuring they will be in business in 25 years for any warranty concerns.

Every component used in our solar panels exceeds IEC (industry standard) specifications at least 300%. One might ask a solar manufacturer how often do they test their solar panels? SolarWorld tests every single solar panel they manufacture, guaranteeing we give our customers the power they expect.

PID or Potential induced degradation is a condition that reduces a solar panel’s performance when a high negative voltage bias to ground exists. Our solar panels have been certified PID free by renown independent testing agencies.

The TÜV Rheinland “Power Controlled” inspection certification is a rare and demanding specification SolarWorld has earned by producing solar panels that have a 2% measuring tolerance. This mark is more proof that our customers are getting the watts they expect, no other manufacturer can claim such precise performance.

Our solar panels have a snow load capacity of 113 psf,  more than double Albany County’s 50 psf snow load. Although this may far exceed the snow rating for Albany, the snow rating reaches 80 psf in Warren County & other counties in New York State.

Plus‑Sorting, noted previously,  guarantees highest system efficiency and reliability. Only solar panels that meet or exceed the designated nominal power in performance tests are shipped. When one of our solar panels is labeled as 275 Watts, we know it makes 275 or 280 Watts (+5), no less.

Our solar panels have special surface coatings and a geometric glass texture which both eliminates glare and acts to trap light within the solar panel (light-trapping). Unique features such as this create value by eliminating a potential nuisance while increasing efficiency.

Our solar panels meet IEC 61701 salt spray test conditions. This affords piece of mind that our solar panels won’t corrode or degrade, even if rock salt is thrown on a solar array to melt ice/snow.

The certification means that our solar panels are rated to 1000 Vdc which far exceeds the prevalent rating of 600 Vdc.

Our manufacturer shares technical data which contributes to global solar energy research, helping the whole planet benefit from their technology.
