A solar panel generates an electric charge, which charges the electric fence energizer battery. The electric 12 volt energizer provides a safe current to the electrified wire on the fence, creating a barrier that discourages unwanted animals from breaching the fence.

A solar electric fence is constructed with the same components as a traditional electric fence but is powered by solar panels which gather energy from the sun. In many cases, these are used in conjunction with an AC/DC charger that converts stored solar energy into DC electricity.

Absolutely not! Solar electric fences use very low levels of electricity. They are at the same energy level as a static shock from walking across a carpet. It will not harm humans or animals and is completely safe to be around after the initial installation is complete.

Solar electric fences are most effective with cattle, horses, and predators. They will deter other animals, but certain predators and wildlife require specialized electric fence systems for deterrence. It is unlikely that they will be stopped by an electric fence wire alone.

The range of a solar electric fence is dependent on the amount of voltage generated and is dependent on how many strands you have. For example, a 10-joule solar electric fence will have a range of 100 kilometers. If you wish to expand your fence you can add additional wire and build your fence up to many kilometers. The general rule is 1 joule will energize 10 km of insulated fence wire.

Electric fences deter bears by providing an electric shock when the animal touches the charged wires. Under normal operating conditions, an electric fence functions as an incomplete (open) circuit with repeating pulses of electricity generated by the energizer sent through the charged wires of the fence. When an animal touches a charged wire, it grounds the fence, creating a closed circuit. An electrical pulse travels through the animal and back to the energizer, delivering a shock to the animal.

Solar water pumps use the energy of the sun to power an irrigation system. These pumps can be used to provide water for a variety of valuable plants, or even your household needs. Solar-powered pumps are ideal for remote areas where electricity is not available, or in times when power outages occur.

A solar water pump moves water using the energy of the sun. It consists of an electrical pump system in which the electricity is provided by one or more PV panels . The typical solar powered pumping system is made up of solar panels that power an electric motor, which in turn power a bore or surface pump.

Submersible solar pumps can lift up to 650 feet and fit in a 4″ or larger well casing and are used when the water supply is deeper than 20 feet from the surface. Submersible solar pumps can operate directly off solar panels, batteries, or in some cases, an AC power source.

Yes a solar powered water pump will work in all seasons

A solar water pump or a solar photovoltaic water pumping system is a system powered by solar energy. It is just like the traditional electric pump with the only exception that it uses solar energy instead of fossil fuel or electricity. It consists of one or more solar panels, also known as solar photovoltaic modules, a motor pump set, electronic controls or a controller device to operate the pump, the required hardware and in some cases, other items like inverters, batteries, etc.

A solar water pump is used for extracting water from ponds, rivers, borewells or other sources of water which are then used to meet the water requirements for irrigation, community water supply, livestock and other purposes.

A solar water pump works like any other pump with the only difference being the solar energy used instead of non-renewable energy for its operation. When sunlight falls on the solar panels it produces direct current (DC) which then feeds the motor to pump out the water. However, in the case where the motor requires an alternating current (AC), the DC produced by solar panels is converted to AC using an inverter.

The advantages of solar water pumps over conventional electric pumps are:

• Solar water pumps do not require any fuel or electricity to operate. Once installed, solar water pumps do not incur the recurring costs of electricity or fuel.
• Does not get affected by power cuts, low voltage, single phase problems or the motor burning.
• Can be installed in remote areas where electricity is unavailable or diesel is difficult to procure.
• Incurs low maintenance costs as solar water pumps have fewer moving parts as compared to a diesel-powered pump and thus, fewer chances of wear and tear.
• No lubricants are required for operation and hence no chances of water/soil contamination due to the lubricants.
• Easy to operate

There are several different types of solar-powered pumps depending on how they have been classified. But primarily there are four types of solar water pumps–submersible pumps and surface pumps, direct current (DC) pumps and alternate current (AC) pumps.

Submersible pumps: As the name suggests, a submersible pump is located deep below the ground level and remains submerged under water. The suction head of the submersible pump is beyond a depth of 10 metres. The installation of these pumps is done by digging a borewell, which leads to an increase in its installation and maintenance cost. 

Surface pumps: The surface pumps remains out of water and in the open. They are installed where the water table is within a depth of 10 metres. As they need to be on the surface, these pumps are easier to install and maintain. They are, however, not apt for deep water table.

DC pump: This pump runs on a motor which operates on direct current, therefore no battery or inverter is needed in this type of pump. 

AC pump: The motor of this pump operates on alternating current, which means the direct current produced by the solar panels gets converted to AC using the inverter. The conversion from DC to AC leads to loss of power from generation and consumption.

The selection is based on the groundwater level and the water source. In the case of a borewell with a water table deeper than 10-15 metres, a submersible pump is used. If it is an open well, pond, etc, then using a surface pump is better. Also, the surface pump is installed when the water level is less than 10 metres.

Based on the classification, the following types of motor pump sets are available:

• Surface mounted motor pump set
• Submersible motor pump set
• Floating motor pump set

Although DC pumps have an advantage over AC pumps in terms of higher efficiency and no requirement of an inverter for operation, the cost of DC pumps is higher. Also, the repair and maintenance of DC pumps are difficult in rural and remote areas due to lack of service centres in these areas.

Yes, there are certain criteria for selecting the location for both the solar panels and the pump. In the case of the solar panels, they should be installed in an area which is shade free and has minimal dust or dirt, has a low incidence of bird droppings and which can provide space for unrestricted tracking movement (keeping the orientation of the solar panels in the direction of maximum solar irradiation). Also, the surface where the panels are mounted should be even. Panels should be easily accessible for cleaning and should be as close as possible to the pump and water source.

The pumps should be located close to the solar panels but within the area to be irrigated. The suction lift for the pump should be low. If there are multiple water sources, the source with the highest water table should be chosen for placing the pump.

Generally, it is said that a 2 HP pump can cater to about two acres of land and a 7.5 HP is said to cater to 10 acres of land, but this data vary depending on the groundwater levels and the type of irrigation required for a particular crop.

The motor pump set for irrigation and domestic drinking water should have a capacity in the range of 0.1 HP to 5 HP. Although, municipal and rural community applications could choose a higher capacity solar pump. 

For a DC motor pump set, the discharge varies from 14 – 100 litres of water per watt peak of PV array while for AC motor pump, the discharge varies from 13 – 19 litre of water per watt peak of PV. The average discharge, however, depends on solar intensity, location, season and other factors. 

Relocation of the solar pump system is possible using a mobile trailer or other means.

No. Lack of sunlight affects the working of solar water pumps. On such days, however, battery power supply can be used to supplement the pump.

The modern day solar panels have adequate safety features and are very unlikely to be damaged by a hail storm. However, in rare cases, a direct lightning strike might cause considerable damage to the solar panels. But the risk of a lightning strike can be mitigated by the integration of an external lightning protection system with the solar array. 

During a storm or a cyclone, the panel gets damaged only if the surface on which it is mounted collapses. In areas prone to cyclones and storms, special consideration should be given to building strong foundations for the installation of a fixed panel. Also, as a precaution during storms or cyclones, the array should be kept horizontally at 180 degrees so that minimum resistance is offered to the wind. 

The system needs very minimal maintenance which includes cleaning of the panels on a regular basis. Cleaning maintains the efficiency of the panel without which the panel’s surface gets reduced exposure to irradiation from the dust and dirt on it. 

In comparison to diesel pumps, solar water pumps have a significantly longer life expectancy and continue to produce electricity for even longer than 25 years.
