Solar Pumping Systems comprises PV panels, solar pump inverter and other equipment for ensuring electrical safety.
- Solar Pump inverter: is an inverter with a variable frequency drive which converts DC current to AC in order to supply the load of the home appliances. Depending on the achieved solar power, the output frequency of the solar pump inverter varies accordingly.
- Solar Pump Drives: are solar based water pumping that depends on the photovoltaic technology for energy generation. As the PV panels convert the solar energy into electricity, the ADV200 SP drive which is connected to the PV panel converts the electrical energy received into mechanical energy. As a result, the pump converts the mechanical energy into hydraulic energy.
Hybrid PV Systems comprises PV panels, hybrid inverter, batteries and other equipment for ensuring electrical safety.
Hybrid Inverter: is made of Grid tie inverter and a battery inverter, by which it is connected to a grid and at the same time operates with a battery bank. The solar power produced in the solar panels is used by the hybrid inverter to charge batteries, in addition to the energy produced by the utility grid. During the absence of the utility grid, the hybrid inverter utilises the batteries’ stored energy.
As previously mentioned, solar trackers increase costs of the solar panels’ installation. The cost of a standard 4 kW, ground-mounted solar panel system is $13,000, which is considered to be around double the cost of a standard 4kW solar pv panel. Tracking equipment’ cost varies from $500 per panel to over $1,000 per panel.
Just as the sunflower tracks the sunlight, there are solar panels that actually follow the sun’s energy. These kinds of solar panels are called solar trackers that are subsequently much more expensive than a regular solar panel. Is it better for a household in a city with less exposure to sunlight to install a solar tracker or more solar panels? It actually depends whether the household has more space to install more solar panels or not, as installing extra solar panels are much cheaper than the solar trackers. However, if the household has no extra space, then the solar trackers are the best solution.
When solar trackers and solar panels are coupled, more renewable energy sources will be produced. Solar trackers can be coupled with either ground-mounted solar systems or rooftop-mounted systems. The equipment of the solar trackers will actually be connected to the racking of the solar panels. There are different types of solar tracking systems which are Manual solar trackers, Passive solar trackers, and Active solar trackers. Manual solar trackers aren’t actually practical as someone is needed to physically move the panels to follow the direction of the sun. On the other hand, the passive trackers include liquid that evaporates by being exposed to the sun’s energy. As a result of evaporating, the system gets tilted towards the sun. The third solar tracker system, Active Solar trackers, are the most practical since they include motors or hydraulic cylinders that cause the solar panel to change direction. However, the parts of the motor could easily break if not used cautiously. Hence, the system should have frequent maintenance which leads to increased costs.
The solar trackers are categorized based on which direction they are moving. If the direction is east to west, then the category is Single axis solar tracker. The production is increased by the single axis tracker by 25% to 35%. The dual axis tracker follows the sun from east to west and from north to south. The dual axis tracker is usually used in households that have no enough space, in order to ensure that enough electricity will be produced.
