Comparison and Selection Guide

Why 1‑Axis Tracking vs. Fixed‑Tilt?

Compared with a hypothetical fixed‑tilt 1MW system at the same site, 1‑axis tracking typically offers:

• 10–25% higher annual energy yield (per NREL and IEA studies)
• Better alignment with daytime commercial load profiles
• Slightly higher CAPEX (here, $80,000 tracking adder)

For Brazilian commercial users with high daytime consumption, the incremental CAPEX is justified by additional kWh and improved LCOE.

Microinverters vs. String Inverters

This configuration uses microinverters, which offer:

• Module‑level MPPT and monitoring
• Higher resilience to partial shading and mismatch
• 96.5% conversion efficiency

For a 1MW ground‑mount, string inverters are also common, but the microinverter choice here prioritizes granular monitoring, redundancy, and simplified DC design. Procurement teams should weigh:

• CAPEX: microinverters may be higher unit cost but can reduce some BOS and design complexity
• O&M: easier fault isolation at module level
• Safety: lower DC voltages in the field

How This 1MW System Compares to Other SOLAR TODO Configurations

Configuration	Capacity	Tracking / Storage	Typical Budget (USD)
Commercial hybrid roof + 200kWh LFP	100kW	Fixed + storage	180,000–240,000
Factory roof fixed‑tilt	200kW	Fixed, no storage	130,000–170,000
Industrial hybrid + 1MWh LFP, single‑axis tracking	500kW	1‑axis + storage	850,000–1,100,000
This BR ground‑mount system (case study)	1000kW	1‑axis, no storage	1,808,800 turnkey

All systems use N‑Type TOPCon or high‑efficiency mono modules with up to 24% efficiency and 30‑year module warranties. SOLAR TODO can integrate LFP storage (200kWh–1MWh) where peak shaving or backup is required, though this specific 1MW configuration is grid‑tied without batteries.

FAQ

Q: What does the $1,808,800 turnkey price include for this 1000kW system? A: The $1,808,800 turnkey price covers engineering, procurement, and construction for a 1MW single‑axis tracking system: high‑efficiency mono modules, microinverters, mounting and tracking structures, BOS components, labor ($300,000), soft costs ($600,000), and project margin. It also includes commissioning and performance verification, but excludes incentives and land costs.

Q: What is the difference between the FOB $1,356,600 and CIF $1,537,480 prices? A: The approximate FOB price of $1,356,600 reflects factory‑gate equipment supply only, with the buyer arranging freight, insurance, and import logistics. The CIF price of $1,537,480 includes equipment plus international freight and insurance to the destination port. Neither price includes local installation or construction services.

Q: How much energy will the 1000kW system in Brazil generate annually? A: The verified configuration produces 1,968,938 kWh in year 1, with a 22.5% capacity factor and 5.2 peak sun hours. By year 25, annual output is modeled at 1,704,140 kWh due to normal degradation. Monthly production ranges from about 108,292 kWh in winter months to 226,428 kWh in peak summer months.

Q: What is the expected payback period and internal rate of return (IRR)? A: The system achieves a simple payback of 6.7 years based on $268,209 in first‑year savings and $27,132 in annual O&M. Over a 25‑year analysis period, the project delivers a 10.7% internal rate of return and $1,742,874 net present value, with total lifetime savings of $4,850,508 against the initial $1,808,800 investment.

Q: How is the $1.81/W installed cost for this project structured? A: The $1.81/W installed cost is built from several components: modules at $85,000 total, inverters at $300,000, BOS at $250,000, single‑axis tracking adder at $80,000, labor at $300,000, soft costs at $600,000, and project margin of $193,800. Incentives are modeled as zero, so all savings come from bill reduction.

Q: Why use single‑axis tracking instead of a fixed‑tilt structure? A: Single‑axis tracking adds about $80,000 to CAPEX but increases annual energy yield compared with fixed‑tilt, especially in Brazil’s high‑irradiance climate. This improves the LCOE to $0.033/kWh and supports a 22.5% capacity factor. For commercial loads with strong daytime demand, the extra generation typically justifies the incremental cost.
