How can Single-Axis Solar Trackers improve your project’s Return on Investment (ROI)?

A single-axis solar tracker positions the panels towards the sun capturing maximum solar energy during the day. Tracking arrays are designed to literally follow solar position at every minute, hour, and day of the year – without requiring manual adjustment.

Gain in Energy Production from Single-Axis Solar Plants

In traditional Solar PV fixed-tilt Plants, the power output follows a bell curve throughout the day, it gradually increases until peaking at noon, then returns to decrease. Whereas, in single-axis Solar PV Plants, we approach the maximum power from early in the morning and this production is maintained until late afternoon. Hence, seeing a performance gain of approximately 25% (Energy Sage, 2019) as compared to the fixed PV installation.

Unlike fixed-tilt traditional Solar PV Plants, single-axis tracking systems require more space per module to allow for the rotation of the PV modules and to eliminate all possible shadowing. However, the latest innovation in the industry is to optimize site design by adjusting the array layout to accommodate greater modules unique to its specific latitude and vertical tilt angle.

10 MW Single-Axis Solar Power Project for Eni Pakistan

For the 10 MW Eni Bhit Gas Field, horizontal single-axis trackers have been used. These are powered by motors and gear trains, through an astronomical clock controller. This is Reon’s first integrated Solar Powered Project for the Oil and Gas sector that shall help Eni shut down one of its gas turbines during the day. The single-axis panels have been installed with wind and precipitation sensors that can immediately detect any unusual weather changes while taking its angle to a 0-degree tilt to minimize the impact of heavy rain or wind.

The use of solar trackers is increasingly on the rise in photovoltaic plants because it allows a significant increase in energy production; hence, improving project profitability. Tracking systems tend to cost more than the fixed-tilt PV Plants but the 25% increase in energy yield could significantly help bring the cost down.

How Virtual Power Plants will change the future of electricity?

Share With:

Virtual Power Plants (VPP) have been the talk of the town and are gaining immense popularity. These are cloud-based distributed power plants that aggregate the resources of various distributed power generating units to enhance energy generation and even trade units on the electricity market.

What are Virtual Power Plants?

Virtual Power Plants (VPP’s) are a network of decentralized, medium scale power generating units such as solar parks, wind farms, and storage systems in a cloud-based setting. These interconnected units are transmitted through the central control room of the Virtual Power Plant but remain independent in their ownership and operation.
The primary objective of a Virtual Power Plant is to forecast, monitor, optimize, and dispatch energy generation and consumption while relieving the load on the grid. This is achieved through intelligent distribution of the power generated by individual units during periods of peak load.

Decentralization and Virtual Power Plants (VPP)

Virtual Power Plants seem to have a promising future by reaping cost-savings and environmental benefits for the grid, consumers, and utility companies. VPP within the distributed system offers a way to forgo capital intensive investments, create grid reliability and operational optimization.

Distributed energy generation at such a scale in Pakistan would need both technological and institutional change that maximizes the use of renewables- especially solar and wind. The good news is that decentralized assets is the now in trend worldwide and VPP’s makes it possible for such smaller assets to get the same regulatory treatment as power plants.
