How to Choose Between a Fixed System and a Tracking System?

Question

Accepted Answer

Choosing the Right System for Your Space When deciding between a fixed system and a tracking system, it’s essential to consider the available space for your solar array. Fixed systems are ideal for small areas, such as rooftop installations, while tracking systems are better suited for larger spaces. For example, if you have a 5-acre property, a tracking system can provide more energy production and make the most of the available sunlight.
Evaluating the Budget and Energy Needs The cost of a tracking system is significantly higher than a fixed system, with prices ranging from $0.50 to $2.50 per watt, depending on the technology and brand. In contrast, fixed systems typically cost between $0.25 and $1.50 per watt. To justify the investment in a tracking system, you need to have a high energy demand or a large space to cover. For instance, if you require 5 kW of energy and have a 2,000 square foot rooftop space, a fixed system might be sufficient. However, if you have a larger area or a high energy demand, a tracking system could provide a return on investment within 5-7 years, depending on the local electricity prices and sunlight conditions.
Understanding the Technology and Maintenance There are two primary types of tracking systems: single-axis and dual-axis. Single-axis tracking systems follow the sun’s movement in the east-west direction, while dual-axis systems track the sun’s movement in both the east-west and north-south directions. Dual-axis systems provide the highest energy production but are more complex and require more maintenance. It’s crucial to consider the maintenance needs and the technology’s reliability when choosing a tracking system. For instance, a single-axis system with a 10-year warranty and a 20-year lifespan might be a better option for a small off-grid setup, while a dual-axis system with advanced technology and a 25-year warranty might be suitable for a larger commercial installation.
