To understand how easy our collectors are to install, please see out collector installation video: |
COMMERCIAL SOLAR WATER HEATING Our Revolutionary Self Return Skyline Collector Design Dramatically Reduces Installation Cost by Reducing the need for Expensive Return Lines.** We Specialize in Lightweight, Much Safer* to Install Water Heating Collectors Need a Low Profile Installation? Need an Architecturally Attractive Installation? Have a Weight Load Issue? Need a No Penetration installation?
WE HAVE THE SOLUTION! Our efficient Skyline® collectors are low-profile and light weight with self-balancing features. They are durable and have a 150 mph wind rating. Far less roof loading means lower cost to the mounting structure and overall collector installation. See more photos of our attractive commercial systems. See: COMMERCIAL CONFIGURATIONS SolarRoofs.com can design the perfect solar water heating system for your business. Call us today at (888) 801-9060
*Skyline® Collectors are much safer to install: Back Injury is the most prevalent and costly source of injury to American workers. A reported 372,683 back injuries occurred in 2001, accounting for 27% of all lost time cases. (US Bureau of Labor Statistics). See: SAFETY **Commercial Skyline® collectors are available with the absorber tubes going through the end of the collectors. Up to 5 “throughput” collectors can be connected end to end. Fed from the center, collectors can be used for a run up to 144’with no return lines needed. See: COMMERCIAL CONFIGURATIONS What We Need To Know To Help You With Your Commercial Solar Water Heating System (Rules of Thumb): 1. We need to know how many Btu's you need supplied. This can be established a number of ways. Find out how many Therms or, if Electric, how many kWh you are using to heat water. If your water heating is not monitored, you can often get an idea of consumption with Gas or Propane by looking your non space heating season bills, usually the cost to heat water is 80 to 95% of this bill. If Electric, your spring or fall, non-heating, non-cooling bill will be your lowest bill and 50 to 70% of this bill can be your cost to heat water. In both cases, it depends on what other uses for energy you have for the fuel. 2. An example of another way would be for an apartment or Hotel/Motel with consistent 7 day a week usage. Figure 10 square feet (s/f) of collector area per person day of usage. A motel with 100 rooms occupied and average of 75% of the time by one person to a room may need a 750 s/f system. This would also cover the laundry. If the Motel has a large restaurant with lots of dishes, a larger system may be needed. 3. A lot of times the system size is limited by available space for collectors and or storage, or simply by budget. This limitation may cause the system to be smaller but smaller systems can be a very cost effective Green investment. 4. If you want us to give you any idea of savings, we also need location and your cost of energy in Therms or in kWh. We also need to know your usage patterns and what the water is used for. 5. You need the collectors to face the sun so you need a good, unshaded, southern orientation (if in the Southern Hemisphere, a good Northern orientation) We need to know how you system will be installed. Be sure to take your orientation readings from True South, not magnetic. 6. Tilt angle is important. The higher the collectors are tilted (from horizontal) the more winter collection they will achieve and the potential for summer overheating is reduced. 7. We need to know if you have a flat roof or a tilted roof and we need to know the material. Pictures are very important for us to help you with this. 8. You need enough space for storage. Depending on your situation, you will need from 1 to 2 gallons of storage per s/f of collector area. Agan, pictures are very important for us to help you with this and we need measurements. 9. Most areas require a heat exchanger but some warmer coastal areas can use open loop systems. 10. You need a good pipe run. You need to be able to connect the collectors to the tank or tank heat exchanger so you need to establish that a pipe run can be made and how long it will be. 11. Depending on the amount of collector used, the pipe size will vary greatly from 1/2" to 3". We need to know the length of the pipe run. 12. Local code, Permits and other issues including roof warranty need to be considered. Cost: Commercial systems "rule of thumb" cost is based on installed cost per square foot (s/f). In general, smaller commercial systems cost more per s/f than larger ones. A solar thermal system can produce up to 50 watts of thermal power per s/f where a PV system can produce up to 15 Watts per s/f. A typical residential installed system costs $150 to $175 per s/f so commercial systems go down in s/f cost as their size increases. Larger installed systems on average cost from $50 to 140 per s/f installed. The lower end is for those who self install and / or have simple installations. The higher end is for Prevailing Wage jobs which adds greatly to the cost. Typical commercial solar water heating jobs over 800 s/f cost from $85 to $110 per s/f installed depending on the level of difficulty. We give basic design help and draft estimates to customers on the above at no charge. More extensive design work, drawing, and plans are done at $100 per hour. We look forward to helping you cost effectively Go Solar!
