Photovoltaic Cells – Solar
These cells are relatively inexpensive, virtually maintenance free and a great source of energy. Photovoltaic cells absorb the energy of the sun and turn it into electricity that can be joined in series with two or hundreds of modules depending on the energy need and space available. Modules are then hooked up directly to the electrical panel to power areas when needed and excess power will be reversed back to the energy provider when electricity is in excess.
Due to the natural abundance of silicon, the semi-conductor material that PV cells are primarily made of, and the practically unlimited resource in the sun, solar power cells are very environmentally friendly. They burn no fuel and have absolutely no moving parts, which make them virtually maintenance free, clean, and silent.
Solar thermal technology harnesses the suns energy for domestic hot water, hot tubs, pools and hydronic (in-floor) heating applications. Flat panels or vacuum tubes are placed on the roof to maximize sunlight and to stay as hidden as possible. This is great way to create a more sustainable home and utilize a clean energy source.
Solar thermal energy can also be accompanied with a steam generator that will create electricity to be used by the home or cycled back to the energy provider when electricity is in abundance. Hot water is then stored in a hot water tank that will be used for domestic hot water when needed.
Heat pumps are one of the most efficient ways of heating homes in British Columbia. Air to liquid heat pumps produce cold or hot water abundantly and efficiently being a minimum of 4 times more efficient than a regular high efficiency boiler. There are several ways to utilize heat pumps such as: radiant in-floor heating, low temperature radiant baseboard heaters, fan coil forced air heating and can be integrated with domestic hot water. Payback on investment for heat pumps can be returned in half the amount of time as solar energy and in BC can be seen as fast as 4 years after installation. These are a great idea for all new home construction and certain renovation scenarios.
