How Solar Electric Systems Work and Power Our Homes

In the wake of growing environmental concerns, the need for renewable sources of energy has seen a dramatic increase. One of the most popular alternatives to fossil fuel is solar power, but how to solar electric systems power our home?
Elements Involved are:
1.     Solar Panels - Solar panel soaks in sunlight and converts it into usable energy.
2.     Photo Voltaic Cells –Photovoltaic cells are made of semiconductor material, commonly silicon.




The Process:
1.     When the sun’s rays hit the cells, the absorbed photons get transferred to the silicon.
2.     The resulting energy from the absorbed light knocks loose electrons.
3.     The structure of the photovoltaic cells forces the electrons to flow in  a specific direction, creating an electric current
4.     Metal contacts placed above and below the cell draw the current away for use by the home
Once the electric current is available it gets directed to Micro inverter which converts Direct Current (DC)from the solar array into Alternating Current (AC), the type of electricity used in our homes.
The Main fuse box divides the current and directs it to:
1.     The electric meter that connects our home system to the electrical grid
2.     The AC appliances that plug into the electrical sockets throughout the home
If possible have your solar power system facing south to get the most sunlight throughout the day
While direct sunlight is best, solar electric systems produce electricity even on cloudy days. If your solar panels produce more electricity than your home uses, the meter spins backward sending electricity back to the grid. This means your energy credits. When there isn’t enough sunlight your home draws power from the grid instead of the solar cells essentially withdrawing the credits that you deposited earlier.

Rain Water Harvesting

Demand for water is growing in most cities as every urban citizen requires almost double the amount of water than a rural citizen. Moreover, India is rapidly urbanizing. Urban population in India has grown almost five times in five decades from (62.44 million) in 1951   to (286.08) in 2001. Not long ago, most of our cities were self-sufficient in meeting their water needs from the extensive urban water bodies to supply water to citizens. Today these water bodies have completely disappeared. Municipalities have been stretched to their limits to find water for the growing urban populations. Groundwater is being extracted by the government as well as the private parties. The term rainwater harvesting is being frequently used these days, however, the concept of water harvesting is not new for India. Water harvesting techniques had been evolved and developed centuries ago. System of collecting rainwater and conserving for future needs has traditionally been practiced in India....

Blue Crete Cement - Innovative Cement Technology

After years of research scientists have invented a new type of cement that is a cross breed of Geo-Polymer and Nano-Ceramic cement. Geo-Blue Crete is a complete low carbon alternative that looks, acts and works like Portland cement but has three times the compression and tensile strengths of Portland cement. It can be distributed in the same way, with the same equipment, at a low manufacturing cost. This new age cement is a one-part system that only requires a simple paddle mixing of its powdered chemical formula at ambient temperatures. The manufacturing process is not dependent on fossil fuels or large kilns. However, it's delivery system remains the same as OPC and the product itself results in a high-performance concrete at 6000 psi and over. It is water retardant, acid retardant, discourages the oxidation of rebar, and has a near-zero coefficient of expansion, which makes it excellent in below-freezing temperatures as well as in tropical regions. It does not trans...
