We are very excited to announce that we have become the first and only SunPower authorized dealer in Park City.  After a year and a half of working toward this very prestigious certification, we have finally become a dealer of the best solar panels on the market.

What does our partnership with SunPower mean for solar in Park City?  Let's take a look 3 reasons On Top Solar's partnership with SunPower will improve the solar market for Park City homeowners.

1. The Most Efficient Solar Panels Made

SunPower currently makes the most efficient residential solar panels available.  Sunpower's Maxeon® solar cell is fundamentally different and dramatically better. 

Its unique copper foundation delivers unmatched reliability and allows SunPower to build panels with the world record for highest efficiency.



SunPower Equinox X-Series

X-Series residential panels convert more sunlight to electricity by producing 38% more power per panel* and 70% more energy per square foot over 25 years.**

  • 345w Panel - 21.5% efficiency
  • 335w Panel - 21% efficiency

SunPower Equinox E-Series

E-Series residential panels convert more sunlight to electricity by producing 31% more power per panel* and 60% more energy per square foot over 25 years.**

  • 327w Panel - 20.4% efficiency
  • 320w Panel - 19.9% efficiency

The high efficiency of SunPower means that you need less panels to produce the same amount of power as traditional solar panels.  Or if you use a lot of power, it means that you can offset more of your usage even with smaller roof areas.


2. The Best Solar Warranty

The SunPower Equinox system is unique because SunPower makes the entire system.  Because of this, they are able to offer the most comprehensive solar warranty.

Traditional solar panel manufacturers will typically have a 10 year product warranty with a 15 - 25 year stepped performance warranty. 

Essentially, if there is a product failure due to manufacturing mistakes, they will replace it within 10 years and if your panels are performing worse than their stated degradation, they will fix your system to ensure it performs as it should. 

SunPowers warranty is a complete 25 year warranty.  They have a 25 year linear performance warranty and a 25 year product warranty.

That means that you entire system is covered for 25 years.  SunPowers panels also degrade much slower, meaning you will produce more power at year 25 than traditional solar panels.

According to SunPower, " SunPower covers 100% of repair or replacement costs, while conventional solar warranties don’t.* Labor, shipping, parts – we’ve got you covered for 25 years.* Plus we guarantee that your panels won’t lose more than 8% of their original power output in 25 years. Compare that to 19% for conventional solar.".


3. The Most Beautiful Solar Panels

It is undeniable that SunPower makes the most aesthetically pleasing panels on the market.

SunPowers Maxeon® design has eliminated all metal lines and strips on the front of solar panels.  That means they look more like a flat glass surface.  Combine that with their Invismount that has no exposed hardware and you get incredibly clean solar arrays.
