Once you decide to go for solar installation on your rooftop, you would need to decide the type of solar rooftop PV system that you want to install. It could be off-grid roof-top or an on-grid solar rooftop PV solar system. For more details on off-grid and on-grid, please refer http://ecosoch.com/power/ For a standalone off-grid solar [...]
It was in year 1800, that first electric light was invented by Humphry Davy. It took next century to make a first commercially available incandescent bulb, a bulb that changed us for ever to nocturnal.  Incandescent’s were soon followed up by Florsecent Lamps, Halogens, HP mercury vapour, Metal halide, High pressure sodium, Low pressure Sodium. [...]
 Solar Micro Inverters existed since the advent of the solar PV systems, but then due to high costs associated with manufacturing, it wasn’t popular until recently when a company enphase made the first commercially successful micro inverter M175 in 2008. Since then many established companies like SMA, Power-One (now ABB), Delta and other companies [...]
There are three type of On grid or grid-tie inverters (for details on what is a grid-tie inverter, you can refer to an earlier post  http://goo.gl/0jtWMl). They are 1. Micro inverter 2. String inverter 3. Central inverter. A Micro inverter is connected a single solar panel to  convert its generated DC current to AC current. This [...]
It’s a common misconception that the solar panels generate more energy with higher temperatures and less energy with lower temperatures. So the assumption is that we have more power generated in places like Chennai than in Bangalore or for that matter in Himachal Pradesh. But in reality,  solar cells, like in all semiconductors  are [...]
Electricity generated by a Solar Photo Voltaic (PV) system can be directly consumed by the load itself or can be  stored in a battery bank or can be sent out to the grid. A solar PV system in which the electricity generated can be sent to the grid is called an on-grid system. This type of [...]
The difference between ordinary fans and superfans is the motor. Motors work on the principle that like magnetic poles repel. The fan blades are attached to a shaft that is connected to the motor. The motor has two main kinds of magnets. A permanent magnet and an electromagnet. The polarity of the electromagnet is changed [...]
71% of the earth is covered by water of which 6% is ice. Therefore absorption of solar energy and evapo-transpiration of water at the earth's surface are dominated by the oceans. These drive the earth's climate system. Heat is transferred frim the equator towards the poles by the atmosphere and the ocean. The atmosphere does [...]
If you follow this link: http://www.amco.co.in/products.php?id=9 , you can see how a battery's weight increases with it's Ah rating. You need bigger batteries to store more electric charge. The capacity of a battery is related to the quantity of active materials and electrolytes in it as well as the surface area of the plates. Electric current is the flow [...]
If you go to their online store, you can see the Ah or Storage Capacity of a range of Exide Lead Acid Inverter batteries. With a terminal voltage of 12V,  you get Ah ratings of 180.00, 165.00, 150.00,  130.00, 100.00,  88.00, 80.00 and  65.00. To know which battery to pick, you must know your load current [...]
