BC Hydro - Solar power for your B.C. business: an update
BC Hydro recently had an inquiry from a business group about how they might apply solar power in lodging and campground-based businesses.
Photovoltaic technologies convert sunlight directly into electricity.
When sunlight strikes the semiconductor surface of the photovoltaic cell, an electrical current is created that can be captured and harnessed.
An emerging approach to producing photovoltaic cells that shows great promise is thin film photovoltaics, where a relatively thin layer of semiconductor is deposited on a low-cost material such as glass or plastic.
British Columbia has a moderate average annual solar resource, with nearly three times the energy available in July and August compared to December and January.
Over the year, a one-kW PV system located in Vancouver will generate approximately 1,000 kWh.
Northwest B.C. has the poorest solar resource, where one kW of installed photovoltaic will generate between 800 to 900 kWh per year.
Photovoltaic systems can be viable and economic in B.C. for off-grid applications to support residential loads in cottages and remote communities, and for non-domestic loads that are not connected to the B.C. grid, such as lighting in park areas distant from the distribution system.
While photovoltaics are still relatively new in B.C., solar hot water is catching on fast.
This technology uses an array of pipes to capture heat energy from the sun (instead of translating solar energy into electricity).
The heat can be used for domestic heating, through radiant heat systems, and/or for domestic hot water.

The solar energy resource in British Columbia is characterized by large
variation between summer and winter.
Part of the cost of the photovoltaic system is offset by the cost of
the material replaced.
BIPV products are high quality construction materials with warranties
that match the lifespan of the solar cells.
Residential BIPV products are limited mainly to roofing materials as
the roof presents the greatest surface area on most residential buildings
suitable for PV.
The most popular approach to BIPV roofing incorporates solar cells into
conventional roofing products such as tiles or metal roofing.

RICHMOND - Vancouver International Airport Authority has installed
the largest solar powered hot water heating system in British Columbia.
The 100 solar panels have been installed on the roof of the domestic
terminal building, and will help to heat an average of 800 gallons of
hot water at Vancouver International Airport (YVR) each day.
Over the past year, Vancouver International Airport Authority and BC
Hydro have worked in tandem to reduce energy consumption and energy
costs at YVR.
The savings associated with the installation of the solar panel heating
system will add to the nearly $2 million saved to-date through various

BC Hydro is exploring the potential for green energy---that is, energy
generated from renewable resources through licensable and environmentally
and socially responsible projects---to contribute to meeting future
demand for electricity in British Columbia.
A potential project for any of these resources would need to be reviewed
to determine whether it meets BC Hydro's Green Energy Criteria.
All projects for these resources have the potential to create GHG credits
and to be considered green energy projects under BC Hydro's definition.
Summary: Wind energy has not yet been developed at a large scale in
B.C., and BC Hydro has focused much effort in the last few years on
exploring and enabling this resource.

a restructuring meant to make the company more competitive.
The next month, BP Solar (Linthicum, MD) decided to close down production
of its thin-film amorphous silicon and cadmium telluride (CdTe) solar
panels to focus on crys-talline-silicon technologies.
Current applications of PV solar panels include providing power to spacecraft
and isolated villages in developing countries, solar-energy systems
in homes and buildings in Western countries (Figure 1), and even powering
the lamps of remote lighthouses.

The most western province of Canada, British Columbia, has benefited
for years from an inexpensive supply of hydroelectric power generation.
However, due to the environmental disruption of large-scale hydro electricity,
much of the new electricity demand is expected to be met with combined
cycle natural gas-fired generation.
In order to meet future electricity demand and maintain low green house
gas emissions, the potential of renewable energy sources and their integration
into the existing electricity supply network must be explored.
Recognizing that Building Integrated Photovoltaic (BIPV) systems reduce
the cost of solar electricity by combining energy production with other
functions of the building envelope, PEARL embarked on several BIPV demonstration
