Elevators working by solar energy
A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps.The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has less environmental impact than pumps powered by an internal combustion engine (ICE). Solar pumps are useful where grid electricity is unavailable .
Off-grid is a system and lifestyle designed to help people function without the support of remote infrastructure, such as an electrical grid. In electricity, off-grid can be stand-alone power system to provide a smaller community with electricity.
Off-grid electrification is an approach to access electricity used in countries and areas with little access to electricity, due to scattered or distant population. The term off-the-grid (OTG) can refer to living in a self-sufficient manner without reliance on one or more public utilities.
Off-the-grid homes aim to achieve autonomy; they do not rely on one or more of municipal water supply, gas , electrical power grid, or similar utility services. A common misconception is that a true off-grid house is able to operate completely independently of all traditional public utility services.
Electricity generated from solar system using solar power got from solar panels. The power generated is called as Direct Current i.e, DC which needs to be converted into alternate current i.e, AC. Usually AC power is used for external applications. So the system is connected to one or more inverters to convert DC to AC. The inverters also help to regulate the current generated.
If the power generation is more from Solar PV System, then the power is reverted back to the grid. The advantage of this is the customer can avail credit for the surplus power generated from the power distribution companies. The in-flow and out-flow of the power can be measured by Bi-directional Meter. This system enables the user to avail Net Metering.
The Power distribution companies pays well to the customers for surplus energy exported to the grid.
One of the best alternative ways to reduce electricity bill overhead charges. Up to 90% reduction in electricity bill is possible
The value can be calculated by using this simple formula:
Net Units = Generated Units – Consumed Units
