Harnessing the Power of the Sun

PV Array

Solar Power Systems

PV modules (or panels) are the solar-electric system's main component, where sunlight is used to make direct current (DC) electricity. Other components in your system such as charge controllers, disconnects, and inverters, enable the electricity from your solar modules to safely power your electric loads. Solar modules are available in many sizes, voltages and formats. Modules are virtually maintenance free and very long lasting (most manufacturers offer 25 year warranties). Solar electric systems are easily expanded and produce no Greenhouse Gases.

Grid Tie with Battery Backup

Grid Tie Array

Same as above, but the inverter also uses electricity stored in a battery bank for backup situations where the power is out. Typically, a limited number of loads are run by this battery bank.

Off Grid

Although they are most common in remote locations without grid service, off-grid solar electric systems can work anywhere. These systems operate independently from the grid to provide all of a household's electricity. That means no electric bills and no blackouts.

Off-grid solar electric systems can be sized to provide power during cloudy periods when the sun doesn't shine. But sizing a system to cover a worst-case scenario, like several cloudy weeks during the winter, can result in a very large, expensive system that will rarely get used to its capacity. To spare your pocketbook, we can size the system moderately. One may consider a generator or hybrid system to get through those occasional sunless stretches.

Backup Systems

Another option is to use an Off Grid style configuration as a Backup System. When there is a power outage, a smaller Battery Bank will power a limited number of loads. A generator may also be tied into this type of system.

Thermal Systems | Terratek - Vancouver Island and Vancouver area, BC - geoexchange

Ocean/Lake Loop – Similar to a horizontal trench, if there is a large body of water available, loops can be anchored down into the body of water which is an excellent source. The idea is to take advantage of the heat storage capabilities of the earth and leverage that using a heat pump to create ultra efficient heating and cooling.

Power Systems | Terratek - Vancouver Island and Vancouver area, BC - micro hydro

As energy becomes more costly, businesses with water processes and municipalities are installing micro hydro turbines as a means of energy recovery - even on potable water systems. If you have a seasonal stream or river, combining a micro-hydro system with a solar-electric system can supply you with year round power.

Thermal Systems | Terratek - Vancouver Island and Vancouver area, BC - hybrid and district systems

When the weather gets cold the geoExchange system pulls heat out of the ground as ususal but with increased efficiency and performance since the ground has a higher temperature. A district heating system is a system for distributing heat generated in a centralized location to provide the heating and cooling requirements in several buidings.

Power Systems | Terratek - Vancouver Island and Vancouver area, BC - wind

Unique to Wind and Microhydro systems, when the battery bank is fully charged, the excess power that the turbine will continue to produce needs to be used by some form of a Dump Load. This power can be stored in a battery bank for later use or fed back to the Utility Grid by way of an inverter. By taking advantage of these two sources, this setup becomes a perfect fit for the Vancouver Island climate.

Thermal Systems | Terratek - Vancouver Island and Vancouver area, BC - solar hot water

Unglazed collectors cost less and typically offer payback periods ranging from 2 to 5 years.These collectors are easy to install and can be integrated in either existing or new pools. Japan and Germany are current leaders in the solar markets, yet BC's climate shows greater solar potential than both countries. Installing a solar thermal system is one of the most reliable and cost effective ways to reduce your electric or gas bill.
