| Navigation
Buoys |
| The
Marine Navigation Services division of the Canadian Coast Guard
is charged with the duty of keeping the waters accessible by providing
navigational aids, developing waterways, and protecting navigable
waters. The navigation aids are either shore fixed or anchored buoys.
In most cases the aids are comprised of a flashing beacon powered
by a small solar array and battery system. The aids serve to mark
hazards and geographic locations. In some cases, the aids are fitted
with a radio transmitter to identify a specific geographic location
for global satellite (GPS) systems.
SPS
has supplied a number of different solar modules to meet the varying
criteria prevalent on both shore fixed or anchored buoys. One such
module is BP85 from BP Solar that incorporates a proprietary ultra
high efficiency laser grooved monocrystalline cell. The BP85 provides
the most power per square meter of any commercially available module,
ideal for an area where space is at a premium.
Another
module used on navigational buoys is the SPS MAR-115. This is a
proprietary 11.5 W module designed by SPS exclusively for the Canadian
Coast Guard to meet some of the toughest marine environmental standards
in the world.
The programs of the Marine Navigation Services benefit pleasure
craft, fishing and commercial vessels, and ensure the public's right
to navigate.

| Lighthouse
Automation |
SPS
designed and supplied 14 solar power systems to automate lighthouses
on the coast of Newfoundland. The systems were supplied to the Canadian
Coast Guard and included over 800 Shell SP-75 Solar Modules, and
the SPS manufactured PV-3 Charge Controller and mounts. System design
and full training was also provided by Soltek Powersource. The systems
power beacons and fog horns in the lighthouses and are located on
Newfoundland's coast.
There are four types of solar systems installed at the various
lighthouse sites that range in size from 8400 watts at the largest
to 525 watts at the smallest. The 8400 W systems consist of four
solar arrays, and each measures 17 m long and incorporates 112 solar
modules.
The power systems use Shell SP-75 solar modules. These 75 watt
panels offer the superior low light level performance of single
crystal cell technology, ideal for foggy coastal areas. They also
feature Shell Solar industry leading 25 year power warranty. Soltek
Powersource manufactures the high-amperage PV-3 Charge Controllers
that will protect the batteries from overcharging and deep discharges.
Digital metering came standard with this model, and Soltek Powersource
added accessories like alarm relays as required. SPS has supplied
power systems to the Canadian Coast Guard for the past eight years.
Past experience has included lighthouse generator to solar conversions
and the delivery of over 2000 modules to power floating navigation
aids by solar. |

| Hybrid Solar Power &
Generator System |
Soltek
Powersouce (SPS) supplied a turn-key solar/generator power system
to service the electrical needs at the Huxley Island Park Warden
Station. Located in the Moresby Island archipelago, Huxley Island
serves as a base camp for parks staff in the region and as a registration
office for visitors arriving by boat. It is also used by visiting
scientists performing studies in the area. The camp has a 2 75 m
building with full kitchen, bunks for 4 people and an office equipped
with satellite telephone VHF radios and computers.
SPS installed a power system consisting of a 600 watt solar array
using eight Siemens SP-75 solar modules, a 4.0 kW TRACE sine wave
inverter, a 38 kWhr lead acid battery bank and a 5.0 kW gasoline
generator. To facilitate installation, all electrical components
were preassembled and 2 wired on a 1.3m “power board”
before shipment. SPS also provided a waterproof, aluminum outdoor
cabinet for the batteries and power equipment which was installed
directly behind the living quarters. A battery state of charge display
and a remote control for the inverter and generator was installed
on an interior wall of the building for the convenience of park's
staff.
One of the key features of the Gwaii Haanas integrated power system
is completely automated operation. The solar system supplies the
majority of the power to the loads, with the generator available
for backup charging using the 100 amp charger in the inverter. In
the event of poor weather or excessive loads, the generator is programmed
to start automatically when 50% of the battery capacity has been
removed. In this way, the batteries are charged before a potentially
damaging low battery condition is reached. |

| Solar Power System |
In
2001, Soltek Powersource provided a custom power system to the Outdoor
Learning Centre project in British Columbia's Golden Ears Park.
This fascinating job included the integration of an alternative
energy system into a First Nations Longhouse.
The local First Nations Band will operate the Centre in conjunction
with BC Parks. The Longhouse will also provide services for environmental
education in the park.
Soltek Powersource installed four 70-watt solar modules, a 1500-watt
inverter/charger system complete with overcurrent protection, and
a 10 kWh battery bank. A DC to DC converter was also installed,
as multiple DC voltages were necessary. Future plans include expanding
the solar modules to eight panels.
The Longhouse is set within a well-treed area that enhances the
aesthetics of the site but does not allow for sufficient sunlight
penetration. Therefore, the solar modules were mounted across two
large poles roughly 15' from ground level in an area with full southern
exposure. However, this new site presented challenges as it is remote
and adjacent to a gravel parking lot. As many people visit the area
unsupervised, a decision was made to add an extra level of protection
for the solar modules; therefore, the solar array was fitted with
a lexan cover on
the face side, and sheet aluminum to safeguard the rear.
The 12VDC interior electrical system consists of four area lights,
three exit signs, two exterior motion sensor lights, and an inline
fan to provide airflow for a fire pit. The inverter system provides
120 VAC for a slide projector and a future food preparation area.
An external VAC receptacle was wired to the inverter's 70 amp charger
to take advantage if using a portable generator should the need
arise. |

| Outdoor Lighting System |
Soltek
Powersource builds outdoor lighting products for signs, driveways,
path lighting as well as decorative lighting systems. The applications
for solar powered outdoor lighting systems are endless.
Even with hydro power nearby, the costs of trenching and installing
underground wiring often make a solar system a lower cost option.
Soltek Powersource offers a wide range of lighting packages from
our flashing beacons to the LED Signlight. We also custom design
and manufacture packages for any application. Systems can be designed
to run for any period of time.
For the Parking Lot Lighting System, pictured above, SPS provided:
- Two 75 W Shell Solar Modules
- Fluorescent floodlight v Aluminum pole and light fixture
arm, powder-coated in white
- Morningstar SunLight-10 charge controller
- Battery bank with two PH 350 batteries
