"On the grid"
Let me start this off by saying that my water, out of the faucet,has a PH level of 7.1-7.3 depending on the time of day as far as I can tell and thus is an ideal hydroponic PH level… SO, I have hydroponic PH level reduction in everything I do because the [...]
Birmingham and the southern part of Alabama are rated Zone 7b-8 by the United States Department of Agriculture although I will be focusing more on what can be grown in Birmingham. This means that the lowest winter temperatures do not dip below 10 degrees F. very often. Birmingham Alabama’s mild winters are warm enough that [...]
5kW Grid-tied complete system featuring a vertical axis wind turbine
Reliable, affordable, independent, clean electricity with zero greenhouse gas emissions!
Wind energy can be converted to electricity easily and cleanly with vertical axis wind turbines. With today’s rising gas and oil prices driving electricity costs higher and higher, it makes sense [...]
Urban Green Energy – Custom wind turbine solutions
By solar power On September 23, 2011 · Leave a Comment · In Clean energy, News, On the grid, Wind energy
At Urban Green Energy’s website one can find the “Build your own wind turbine” tool where you really can design your own setup. Grid tie vs battery backup, tower size, color of the turbine, etc. Who knew that one company could bring it all together in a [...]
NISKAYUNA, N.Y.
General Electric Co. on Thursday said it will focus on low-cost thin film photovoltaic technology as part of its efforts to develop a cheaper, more efficient solar module to compete in the growing alternative energy market.
GE plans to harness cadmium telluride technology from PrimeStar Solar Inc., a start up firm that [...]
U.S. Sen. Mark Udall (D-Colo.) announced Wednesday a new bill intended to boost solar energy production by extending solar tax credits to residents who invest in community solar farms to power their homes.
The bill is the first of a series of clean energy bills Udall plans to unveil. He said the legislation was inspired [...]
Other Thin Films
A number of other promising materials such as cadmium telluride (CdTe) and copper indium diselenide (CIS) are now being used for PV modules. The attraction of these technologies is that they can be manufactured by relatively inexpensive industrial processes, certainly in comparison to crystalline silicon technologies, yet they typically offer higher [...]
Amorphous Silicon
Amorphous silicon cells are composed of silicon atoms in a thin homogenous layer rather than a crystal structure. Amorphous silicon absorbs light more effectively than crystalline silicon, so the cells can be thinner. For this reason, amorphous silicon is also known as a “thin film” PV technology. Amorphous silicon can be deposited [...]
Thick-film Silicon
Another multicrystalline technology where the silicon is deposited in a continuous process onto a base material giving a fine grained, sparkling appearance. Like all crystalline PV, this is encapsulated in a transparent insulating polymer with a tempered glass cover and usually bound into a strong aluminium frame.
Multicrystalline Silicon Cells
Made from cells cut from an ingot of melted and recrystallised silicon. In the manufacturing process, molten silicon is cast into ingots of polycrystalline silicon, these ingots are then saw-cut into very thin wafers and assembled into complete cells. Multicrystalline cells are cheaper to produce than monocrystalline ones, due to the [...]
