Community of green energy, renewable power, electrical machinery, automation, process control...

But we hope more of you will participate in this community for living green, eco-friendly life. The environment is becoming worse now. It's our choice to going green, environmentally friendly.

We can choose more renewable energy, such as bioenergy, wind power, solar energy, hydropower... We can use hybrid automobiles or electric cars... We can reduce our energy consumption or water consumption...

There are so many

Solar energy: Solar panels can be used to convert the sunlight into electrical energy. Some achievements of solar energy have been achieved during these years.
 

Wind energy: Wind turbines are connected to the generators, turn to generate electrical energy.

Hydropower: In the hydro-electric plant, water is stored in a reservoir. The water's potential power is converted to kinetic energy as it is piped into turbines that are connected to the generators.

Geothermal power: Geothermal energy harnesses the heat of our Earth to provide heating & electricity.

Biomass: Biomass is organic matter that can be converted to provide heat or electricity.

The sales of solar power panel were 5.6GW in 2008, which is up 48 percent. In 2008 3.3GW or 60% solar panel sales was produced in Asia. And about 1.5GW solar energy panel sales was produced in Europe. Only 750MW solar power panel sales was produced in the United States.

 

The downturn of alternative energy (green energy, renewable power) happened in 2009, and the manufacturing capacity utilisation was below 50%, which is similar to the semiconductor-for-IT industry. But in 2010 the solar panel market is picking up again

There's one revolutionary advancement for the development of solar energy. Caltech (California Institute of Technology) researchers claim they have developed a solar cell that is twice as efficient as conventional solar wafers and that could be much cheaper to make.

Using silicon-wire arrays, Caltech researchers claim they can trap up to 96 percent of incident sunlight at a single wavelength and up to 85 per cent of the collectible sunlight, then convert between 90 and 100 percent of it into electrons, aka electricity, surpassing previous optical microstructures developed to trap light. As we know conventional photovoltaic (PV) cells convert about 40% of the sunlight they absorb into electricity.

Solar energy is a kind of cheap energy source for Africa, clean, green, free, without pollution or damage to the environment.

Electrifying the rural areas poses great challenges for African governments. Remote and scattered, rural homes, which are unlike homes in the urban areas, are costly and often impractical to connect to the main electricity grid. But stand-alone sources of power, such as solar energy, wind energy and power from mini-hydro generators, can help to fill the gap of remote and scattered, rural homes. In Africa solar power, which is clean and renewable, fits the demands.

The sun is free and inexhaustible.

Benefits with home green power (renewable energy, eco power) include:

Home security
Family protection 
Increase in home value
Fixed cost for electricity
Clean (and sometimes quiet) power production
Free, renewable, green fuel
Reduction of emission of greenhouse gasses
 

According to the statistics, before October, 2009, there are about 50 companies, which are constructing , expanding, or preparing to construct the production line of multicrystalline (poly-crystalline) silicon in more than 20 provinces in China. The scale of the construction for multicrystalline (poly-crystalline) silicon is 50,000 tons to 100,000 tons.

Regarding the wind power, there are about 70 manufacturers of wind energy now for just several years in Chna. But in fact the demands for wind power in the market of China, the capacity of the first 3 manufacturers are enough fully. That means other 67 manufacturers can't find enough demands of the market for their wind power.

 

But this is not the most serious problem these companies of renewable energy face.

This biggest problem is off-grid (stand-alone) for these clean energy (solar power, wind energy).

Home solar power systems (residential solar energy systems) are not as hard to set-up as in a commercial or industrial setting. Generally a home solar power system (residential solar energy systems) can handle about 60% to 80% of household electricity needs.

In fact we don't have to be an engineer to build this home solar power system. Homeowners can develop their own solar energy system at home by following a few guidelines from a book about this. Setting-up a home solar power system may require a couple of solar panels of photovoltaic cells and a rigged system that includes wiring, an inverter, distributor and storage batteries.

Nowadays more and more home solar energy systems (residential solar power systems) are used in our life. Although solar energy is green and eco-friendly, there are still some questions before applying these systems.

What do I want this home solar energy system to do?

Will the home solar power system you build or have installed act as a backup power source only?

Or do you expect to be able to use your home solar energy system to meet all of your energy needs, which include the home heating, hot water, lighting and the running of all your appliances?

Residential solar panels are meant for residential (home use) rather than commercial. With the use of residential solar panels, we can benefit from both indoor and outdoor lighting, backup power, solar water heater, water pumps, pool heaters, and covers to utilize the solar energy (solar power) in the best possible way.

Get the best residential solar panels and save yourself from the inflated energy bills, such as electricity bills. Make sure you conserve the environment by harnessing renewable energies (green energies), reducing the green house effect and global warming.
