The need for an on-grid and off-grid solar system arose due to two main issues:
 -The increasing cost of commercial electricity.
 -The harmful effects of fossil-fuel-based electricity on the environment.

People started looking for better options; hence, the wide-scale use of solar systems to generate electricity became popular.

Moreover, high-efficiency solar panels facilitate the production of electricity to power the industrial sector as well.

However, to choose the best solar energy generation system, it is crucial to know the differences between an on-grid and off-grid solar system.

Although solar system installers provide the necessary guidance to select the ideal option for your power requirements, it is always better to do some research on your own.

If you want to know the critical aspects of these two solar systems, you have come to the right place. Let us dive deep into understanding both of these models in detail.

What Is an On-Grid Solar System?

The on-grid solar system is also referred to as a grid-tied system.

It can produce surplus electricity that can meet the energy requirements of not just the residential sector but also the commercial and industrial sectors.

The first basic requirement of installing this system is the presence of a grid. Out of the units that solar panels produce during the day, whatever is not being consumed is transferred to the grid.

The transferred units are imported from the grid at night. And here's the brownie point: if the solar panels don't produce enough electricity due to unfavourable conditions on a certain day, the consumer can use the power from the grid.

So, no matter the scenario, your house gets electricity. Also, this system does not require a battery. Your grid is your battery!

What Is An Off-Grid Solar System?

An off-grid solar system functions independently. People don't need to connect solar panels to any grid. However, this system requires a battery backup to store the solar power generated during the day.

The off-grid solar system consists of solar panels, a charge controller, a battery, mounting structures, and an inverter. The solar panels capture sufficient sunlight during sunshine hours and the battery stores excess charge to power all the electrical appliances at night.

This system is self-sustaining and ideal for areas with no power grids.

Solar pump definition is, as the name suggests the pump uses solar energy to function. Solar-pumps are robust, installation is simple, minimum maintenance is necessary and very expensive when we compare with normal water pumps. The life span of these pumps is a maximum of 20 years. But time to time the solar panels need to be cleaned for running. These kinds of pumps mainly used where there is an electricity problem otherwise consistent power supply is not accessible.

How Does Solar Pump Work?

When the solar energy drops sun rays on the PV panels then the solar panel converts the rays into electrical energy with the help of Si wafers fixed within the PV panels. Then the solar energy supplies to the electrical motor to operate the pumping system using cables. By the revolution of the shaft which is fixed to the pump, then the pump begins to pick up the soil water and supplies to the fields.

Solar Pump Types

The solar-pumps are classified into four types namely submersible solar pumps, surface solar-pumps, DC pumps, and AC pumps.

Submersible Solar Pumps

These pumps can lift the water up to 650 feet and fit within a big well. Whenever the water deepness in the well is above 20 feet from the surface then these pumps can work straightly

Solar Pump Applications

The applications of solar pumps mainly used where pumping water is required.
 *Water supply for animals.
 *Water supply for harvest irrigation.
 *Water supply for Cooking and Drinking water supply.
 Thus, this is all about an overview of solar pumps. From the above information, finally, we can conclude that these pumps are very efficient compared with traditional ones. These pumps are extremely used in small scale for farmers, horticulture farms, cattle feeding, irrigation, gardens, etc. Furthermore, these pumps are also used in gas and oil extraction.

Street lights have been in use since the Roman and Greek civilizations. Before the invention of incandescent lamps, oil lamps, candle lighting and gas lamps were used to illuminate the streets for public safety. In 1878, the first electric street light was used in the cities of France. With time, cheaper and brighter incandescent lamps replaced arc lights. Today, conventional street lights use high-pressure sodium lamps.

*LUMINARY

Any lighting unit which houses one lamp or more than one lamps along with the parts which are designed to distribute the light and to protect and power the lamps is called a luminary. A solar street light also has a similar light-giving body.

*SOLAR PANEL

A solar panel is composed of many solar cells that generate power to run a solar street light. It is a device that is used to absorb sunlight and convert solar energy into electricity to light up solar lights. The two main types of panels are:
  -Polycrystalline
  -Mono crystalline
Polycrystalline panels are commonly used due to their affordability and they offer the same performance even in high temperatures. Monocrystalline panels are expensive and can perform better in cold climates.

*BATTERY

A solar battery is a type of battery that gets charged with energy from solar panels. Modern solar street lights use:
  1. Li-ion batteries
  2. LiFePO4 batteries

*CONTROLLER

Solar controllers are charge regulators that regulate the flow of current going from the solar panels to the batteries. They prevent backflow of current from the battery to the panel and also overcharging and undercharging of batteries. Solar street lights use:
  1. MPPT controller
  2. PWM controller

MPPT controllers are highly priced, more efficient and work better in cooler conditions. PWM controllers work well in smaller power systems and are cheaper.

*Types of Solar Street Lights

  1. All in one or fully integrated solar street light
  2. Integrated or all in two or split solar street light
