SP TEL- Sol™
Proving again that they are a leader in renewable energy development, Sacred Power Corporation has developed an entirely new product for the Telecom industry with the advent of the SP TEL-SOL™. The passively heated and cooled telecommunication shelter, which incorporates the best of solar electric and solar thermal technologies, will become the standard for housing remote telecommunication equipment.
System Description
The unit, designated the SP TEL-SOL™ is designed based on the need by the Telecom Industry, to economically power, heat & cool equipment enclosures or shelters that are located in remote areas and have limited access to utilities. Maintenance free, fully automated, and ready to be delivered to remote sites, the SP TEL-SOL™ provides the solution with the features never before seen by the Telecom Industry. These features include the following:
- Patented Cool Cell Technology-for cooling and heating (uses no electricity)
- Roomy 8'x10'x9.5' Enclosure for repeater racks and electrical equipment
- All Steel Construction with weather-tight Industrial Grade Enamel finish
- R-30 Insulation in walls, floor and ceiling, Non-Conductive Vinyl Floor Tile, Panolam Inner Walls and Ceiling
- Skid mounted on 4' I-Beams including forklift ports and varmint shield
- Heavy Duty 3' x 7' Entry
- Energy Efficient Lighting-Inside and out (20A 120VAC)-Receptacles Inside
- Interior Halo Grounding-#2 Stranded copper
- Compact size and transportability, but heavy weight for stability
The SP TEL- Sol™ is designed for high quality through manufacturability resulting in low cost. The system is built and tested in a controlled environment. Once delivered, the unit is completely operational. The only on-site "construction" is the attachment of the optional SP Solar HYBRID Power System, other conventional power source and any other equipment such as communication or wind generator tower and/or back-up power generation equipment.

The use of Cool Cell™ passive cooling technology enhances the life and the reliability of the equipment located inside the shelter by reducing the ambient temperature within the enclosure. The fluid absorbs the heat generated by the equipment during the day and releases it at night while at the same time absorbing the cooling effects of the night air and providing chilled fluid for a cooling effect inside the shelter the following day. Alternately, during cold weather, heat is transferred from and external solar collector, located on the south-facing side of the building, to the existing thermal storage tank located on the inside. Both cooling and heating are based on natural convection resulting in little or no electric usage.
Cold Weather Performance (Sandia Crest Data)
Lowest mean temperatures are in January and February at 20°F. Average daily winter shelter temperature will be 20°F + 18°F=38°F. On sunny days the solar heating system will add an additional 6,000 Btu/day or another 16°F to 38°F base temperature for an average shelter temperature of 54°F. When temperatures are colder shelter temperatures will also be lower. If more heat is required the solar heating systems can be easily up sized to meet the demand.
During extremely cold, cloudy weather the thermal mass of the water with the shelter provides 184, 320 Btu's of heat as it freezes. This heat is enough to guard the shelter from subfreezing temperatures for 10 days at -17°F temperatures. At times when the weather is colder than normal and additional heat is required, a 300 watt electric heater is provided for back up.
Warm Weather Performance (Sandia Crest Data)
Internal shelter temperatures will be in the high 60's to low 70's. Lower elevations-6,500 ft. -Shelter temperatures will be in the high 70's to be 80's. A 2000 BTU thermo-electric air conditioner is offered as an option.

The SP TEL-Sol™ with SP Solar HYBRID Power System Option
When equipped with an optional SP Solar Hybrid Power Systems the TEL-Sol™ truly becomes the answer for all remote telecommunication applications that are beyond conventional power.
The SP HYBRIDS are all equipped with true sine-wave power conditioning units that ensure all internal electrical equipment operate smoothly. Dual-axis trackers provide more power versus the use of affixed or seasonally position adjusted type photovoltaic module mount. They include the use of Industrial Grade Deep-Cycle Maintenance Free Gel Batteries which alleviates past problems dealing with the frequent customer servicing of batteries. Larger SP HYBRIDS include high-power generators combined with dedicated large propane tanks which back-up the solar power system during continuous cloudy weather. The projected 30-day supply of fuel mirrors regular deliveries by the Propane Company. And finally, like the SP-TEL-Sol™ they are pre-manufactured ready for plug-n-play operation.
