Solar Modules

A SOLAR ELECTRIC MODULE WORKS LIKE A CAR BATTERY CHARGER... EXCEPT INSTEAD OF PLUGGING IT INTO THE WALL, YOU PUT IT OUT IN THE SUN.

PHOTO-VOLTAIC or solar cells convert sunlight directly to electricity within wafer thin cells. Light "particles" called photons actually bounce electrons across a barrier, creating an electrical current. About 36 cells are built into a 4 to 12 square foot solar module. Cells are sealed within a tough resin between a tempered glass front and plastic or foil backing, then framed in aluminum rail. There are many sizes and brands of modules, at similar prices, specifications, and claims. New brands come each year, many as good as, but none better than, the proven reliable brands listed in the next pages. Considering cost and length of module lifetime and warranty, we stock the longest tested and most respected brands.

DIRECT SUNSHINE with no shadows is absolutely necessary for full power. Partial power is produced on overcast days, but any shadows falling directly on a solar module will reduce power, regardless of what some advertisements claim.

DURABILITY: First used 40 years ago for space satellites, modules of that vintage still operate unless the glass has been broken or water has entered the seals. Life expectancy of solar modules is over 30 years. Most photovoltaic modules come with a 20 to 25 year warranty on power output and may last a lifetime.

THE AMOUNT OF POWER a solar array produces depends on the number of modules you use and the number of daily sunshine hours in your climate. Overcast days with only half normal brightness give half of normal power. Some climates allow much more power in summer than winter. Solar modules can easily be added to your array to increase power as your needs grow. Modules are rated by volts, watts, and amps. The AMP rating is the best indicator of the charging you get and is what you will see on your meter during ideal sun conditions.

Helios Solar Works manufactures high-performance crystalline solar modules for solar electric

Schott Solar has been a leading global developer and manufacturer of solar products for over 52

years. Engineered in Germany, the high quality Schott Solar PV modules are extremely durable and reliable as demonstrated in several important ways:

Industry leading warranty: Schott Solar offers an industry leading linear power output warranty for 25 years in addition to five years warranty for any defects in materials or workmanship. This enhancement provides 6% more guaranteed power over the 25 year period compared to standard step-down warranties common in the industry.

Narrow output tolerance: Schott Poly modules are among the industry leaders in lower output tolerances. Schott Solar sorts all modules to a positive tolerance (minus zero watts) which provides for a stable, high energy output you can feel secure in.

Long-term reliability: SCHOTT modules are environmentally tested to double the industry certification standards for thermal cycling and damp heat tests to ensure consistent and superior performance over the long term. In addition, SCHOTT has performance data from over 25 year of actual field testing the supports our high quality products.

High resistance to mechanical loads: SCHOTT Solar modules are tested to an extreme loading pressure of 5,400 PA to ensure additional security for your investment.

Up-to date features: SCHOTT Solar modules offer up-to-date electrical features such as double insulated PV cables for use with transformerless inverters and locking connectors.

These SolarWorld PV modules are designed for use in a wide variety of applications from off-grid residential systems using a MPPT charge controller to high-voltage grid-tie commercial systems. The modules use 60, six-inch semi-square mono-crystalline cells in series behind tempered glass within a silver aluminum frame. They have a sealed junction box with bypass diodes and 37.4 inch long output cables with Multi-Contact locking connectors (MC4). The Sunmodule is certified to the stringent safety and design requirements of UL1703 and IEC 61215. All US Sunmodules are currently produced in the ISO 9001:2000 certified Camarillo, California facility. SolarWorld also offers end-of-life module recycling for all Sunmodules.

SolarWorld bonds the tempered glass laminate deep into the aluminum frame with a continuous bead of silicone adhesive. This method guarantees exceptional rigidity for the entire module and prevents the frame from loosening or pulling away from the glass. UL Load rating is 75 pounds per square foot which shows that the module can withstand heavy accumulations of snow and ice.

Sunmodules have a +/-3% power tolerance and a 10-year 90% power warranty, 25-year 80% power warranty. 5 year manufacturers warranty.
