Royall Solar Systems:

Royall has taken the history of being a green company and engineered a widely popular product for the solar energy industry.  Amazing how you can take the power of the sun and heat your home.  Now you can take the luxury of buring wood and coal for the winter months and also incorporate solar.  Please take a few minutes and read the information below to help make your decisions moving forward with solar power manufactured by Royall Manufacturing, Inc. 

Solar Water Heating has been used for hundreds if not thousands of years to heat water.  With advances in technology, solar water heating systems have become more and more efficient, with Evacuated Tube Solar Water Heating offering effieciencies of well over 90%.  That means that more than 90% of the sun's energy landing on a surface is converted into heat which can be used to heat water.  This is also one of the cheapest renewables; with costs starting from pennies per Watt required comparing to dollars per Watt for PV Solar and Wind Turbine power generation.

Vacuum or Evacuated Tubes are made from glass - typically ultra - strong and heat resistant Pyrex with a double wall constrction.  The glass on the inner tube is coated on its outer surface with an absorbent coating, and on its inner surface with a reflective coating.  Inside each tube all air is removed making a vacuum and a copper heat pipe is located through the center of the tubes.  Most of the infra - red radiation from the sun is absorbed by this sealed heat pipe which contains an anti - freeze type liquid. 

As heat rises, hot vapors from the antifreeze rise up to the top of the heat pipe where its copper tip connects with a header pipe through which more antifreeze flows.  This hot antifreeze is then pumped through pipes inside the hot water tank with the end result that the water gets hotter and the antifreeze cooler.  The antifreeze then continues its journey around the system and back out to the solar water heater to be reheated.

The copper at the tip of the heat tube can reach well over 390 degrees easily heating water to 194 degrees Fahrenheit on hot days and to 140 degrees Fahrenheit even in the winter.  This simple system is completely sealed and needs minimal maintenace over its 20 plus year life.

• Rays from the sun heat the solar tubes
• Heat rises from the tubes to heat antifreeze
• Hot antifreeze comes into your house and heats water
• You use the hot water
• Cold antifreeze gets taken back out to the solar tubes
• The solar tubes heat the antifreeze
• The cycle continues

Many people have the false belief that Solar Energy cannot work in the Northeast or the Midwest - states like New York, New Jersey, Connecticut, Massachusetts, Minnesota, Wisconsin, Illinois and others, because the winters are too cold, too long, days are too short and it is too cloudy there too often.

The truth is Solar Hot Water is incredibly efficient and cost - effective in the Northeast and Midwest.  This is because of a newer technology - Evacuated Tube Solar Collectors.  Evacuated Tube Solar Collectors have many advantages over traditional solar collectors, including:

• Unique 360 degree design increases collection earlier and later in the day
• Increased freeze - protection offers better operation in winter time and colder climates
• High BTU Outputs
• Cost - Effective and affordable pricing
• Short payback periods and high returns on your investment
• Can be used for domestic hot water
• Can be used for pool/spa heating
• Can be used for radiant home heating
