How much does a solar tracker system produce?

September 05, 2025

Those who choose to install a photovoltaic system aim to achieve the highest possible performance.

One of the most effective technologies to increase energy production is the solar tracker, an intelligent mechanical system that allows the panels to follow the sun’s path throughout the day.

But how much energy does a system with a solar tracker actually produce compared to a fixed structure? And what are the factors that affect its efficiency?

In this article, we analyze the figures, variables, and advantages of this technology, referring to the solar tracking systems designed by Solward, among the most advanced on the market.

What is a solar tracker

A solar tracker is a structure that allows photovoltaic modules to move in order to maintain the optimal angle of incidence with respect to the sun.

Unlike fixed structures, which remain static throughout the year, the tracker automatically adjusts the position of the panels, maximizing the solar radiation received.

There are two main types of tracking systems:

Single-axis: the panels move along a single axis (east-west), following the sun from morning to evening.

Dual-axis: adds a second movement (north-south), for even more precise inclination.

Single-axis systems are currently the most common solution in the utility and industrial sectors, thanks to their balance between energy yield, cost, and maintenance.

How much energy does a system with a solar tracker produce

The yield of a plant depends on various factors: geographical location, orientation, panel quality, and weather conditions.

However, under optimal conditions, the use of a solar tracker allows for an average increase in production between +25% and +35% compared to a fixed structure system.

Here’s a comparative example:

These values may vary depending on latitude and tilt, but they clearly demonstrate how a solar tracking system increases energy efficiency and reduces the payback time (ROI).

Why does a solar tracker produce more?

The principle is simple: a panel exposed perpendicularly to the sun’s rays always produces more energy than one with a fixed tilt.

The solar tracker continuously follows the sun’s position, maintaining the best possible angle of incidence throughout the day.

In Solward systems such as Tracker One and Tracker Agro, efficiency is further improved thanks to:

• 3D backtracking algorithm, which prevents shading between module rows.
• ZigBee wireless communication, which reduces cabling and improves remote management.
• Independent self-power supply, ensuring continuous operation even without grid connection.
• Compatibility with bifacial modules, capable of capturing light from the rear surface as well.

All these elements help maximize real production, making the tracker an ideal choice for industrial, agricultural, and agrivoltaic installations.

Example of annual performance

To better illustrate the benefit, let’s assume a 1 MW ground-mounted photovoltaic system installed in central Italy:

• Fixed structure: 1,400 MWh/year
• Single-axis tracker: 1,820 MWh/year
• Difference: +420 MWh/year

Considering an average energy price of €0.12/kWh, the increased production equals over €50,000 in additional revenue per year.

This shows how a solar tracker, despite a slightly higher initial investment, allows for a faster and more sustainable economic return over time.

When is it worth installing a solar tracking system?

The installation of a solar tracker is worthwhile whenever the increased energy production offsets the system’s additional cost.

It is particularly advantageous when:

• The site has good solar exposure and sufficient spacing between rows.
• It involves systems above 200 kWp or solar farms.
• The goal is to maximize profitability per hectare or per installed MW.
• The system is intended for agricultural or industrial self-consumption, where the energy produced is used directly.

Maintenance and lifespan

A common misconception is that trackers require extensive maintenance.

In reality, modern solar tracking systems, such as those designed by Solward, require minimal maintenance, limited to periodic checks on actuators, screws, and electrical components.

Their service life exceeds 25 years, thanks to galvanized materials and anti-corrosion treatments that ensure durability even in harsh environments.

Frequently asked questions about solar trackers

How much does a solar tracker cost?

The price depends on the type of system and plant capacity, but the additional cost is recovered in a few years thanks to increased production.

Does it require a lot of maintenance?

No, Solward systems are designed to operate with minimal, scheduled maintenance.

Is it suitable for agricultural installations?

Yes, particularly the Tracker Agro has been developed specifically for agriculture, with increased height and reinforced structure.

Does a tracker-equipped system work on cloudy days?

Yes, the trackers still follow the sun’s calculated path using the astronomical algorithm, optimizing diffuse light as well.

A photovoltaic system with a solar tracker can produce up to 35% more energy than a traditional one.

Choosing a Solward solar tracking system means investing in innovation, efficiency, and sustainability, with the reliability of a product tested and certified in Italy.
