Solar power systems are of two types one is on-grid and other is off-grid systems. Which one is better to use and how it works? Read here to know which grid system is best fits to your home.
On-grid or grid-tiedsolar power systems generate energy when it is connected to the local utility grid. In order to function these systems are connected to the grid. When you are overproducing power, these on grid systems send extra generated power back to the grid that helps you reserve it for later use. Here your utility system itself acts as your battery storage it means these systems works without batteries.
Here grid interactive inverter plays a major role. The inverter converts DC current produced by the solar panels into AC current which is required to power your home. That means energy freely passes from renewable source to the utility system via grid interactive inverter. If, the renewable source produces more energy with your system than you need the excess electricity you are not consuming is sent back to your utility grid's company. In this way, you can earn money by selling your excess energy to the utility company. At the same time when your system is not producing energy, you can retrieve energy from utility grid with the help of inverter.
1) Electricity grid works without battery and saves the cost of battery here
2) Can earn money directly from your rooftop by sending extra current to the utility company
The off-grid solar power system is independent of grid, instead, a wide range of equipment is needed for example solar panels, solar power controllers, solar cables, battery, off grid inverter etc. The off-grid solar system helps you to save energy in a device called a battery. During the daytime energy produced by the renewable source can be sent into batteries as well as supplied to your home. The energy stored in the battery can be used later, during the night or on a cloudy day.
The power generated by the solar panels initially charges the battery with the help of charge controller. DC current supplied to the inverter can be converted into AC current which is used for household appliances. Sometimes your renewable source over-produce energy these can be stored in the battery and use it later.
1) In case of regular back outs, the off grid system is very suitable
2) These are less expensive when compared with on-grid where utility wire to be stretched to property
3) These systems provide efficient power which benefits the environment
Moreover, in all locations, On-grid system is not suitable, of course, all say Off-grid solar systems are costly for the equipment like battery, inverter etc. But in real Off-grid solar are still cheaper than paying to be connected to the grid.
However, the choice of the system lies with you. We offer Off-grid installation services with warranty schemes. For best offers visit our website www.naturalpower.in and contact us for more details.
