All Solar Panels Are Not Created Equal


Like many other products, solar panels are made in various countries and made with different materials that can have an effect on their quality.  At American Sentry Solar, we use top-tier quality solar panels made from monocrystalline.  The solar cells made from crystalline silicon are almost magical devices.  They take sunlight shining on them and convert them to electricity.  You may be saying to yourself mono-what?  Well you're not alone, that why we felt it was necessary to go over the different types of solar panels as well as their advantages and disadvantages.

Monocrystalline Solar Panels


  • Monocrystalline solar panels use the highest grade material that produces up to or more than 20% efficiency rates.  
  • Compared to other panels Monocrystalline are the most space efficient.
  • Monocrystalline panels will last the longest with warranties that usually stretch for at least 25 years.


  • The main disadvantage of monocrystalline is the cost.  Even though these are the most expensive, you will have the highest quality and generate the most with monocrystalline panels.

PolyCrystalline Solar Panels


  • Polycrystalline solar panels are easily made and wastes less silicon compared to monocrystalline panels.
  • Polcrystalline panels don't cost as much due to the process it takes to make them, however they aren't as efficient.


  • Only produce 13-16% efficiency 
  • Poor rooftop appeal
  • Space limitations

 Thin Film Solar Panels


  • Great rooftop appeal
  • Less expensive than other options
  • High temperatures has less impact on the performance of the panels


  • Not a common option for residential homes
  • Need to have a lot of space to install
  • Doesn't produce as much as monocrystalline in the same amount of space.
  • Shorest warranty compared to other panels

Every option ultimately has its advantages and disadvantages, however monocrystalline panels are your best option because of its efficiency and durability.  Thanks for taking the time to learn about the different types of solar panel options.
