The global solar PV mounting systems market is experiencing an unprecedented surge. Valued at over USD 47 billion in 2025, it is projected to reach nearly USD 70 billion by 2034, growing at a CAGR of 4.47%. This rapid expansion lies in a wave of innovation—from advanced anti-corrosion materials and extreme-weather-resilient designs to the rapid emergence of agrivoltaics and integrated solar carports. For project developers, EPCs, and procurement teams, understanding these mounting structure trends is no longer optional—it is the key to unlocking lower levelized costs, longer asset lifespans, and higher energy yields.
This article explores the five most important solar mounting structure trends shaping the industry in 2026, and how leading manufacturers are adapting their engineering strategies to meet these evolving demands.
1. The Material Revolution: Aluminium, ZAM Steel, and Anti-Corrosion
The solar mounting structure is the backbone of any PV installation. It must endure 25–30 years of UV exposure, wind stress, humidity, and in many regions, salt spray and chemical pollutants. Material selection directly affects structural longevity, maintenance costs, and total cost of ownership. The industry is now moving beyond the traditional binary choice of hot-dip galvanized (HDG) steel versus standard aluminium.
The Rise of ZAM Steel
A third contender, Zinc-Aluminium-Magnesium (ZAM) coated steel, has been rapidly gaining ground, especially in utility-scale solar projects. ZAM steel achieves its superior performance through a ternary alloy coating: zinc provides baseline corrosion protection, aluminium enhances atmospheric resistance, and magnesium dramatically improves cut-edge corrosion resistance—a common failure point in traditional galvanized structures. This coating is reported to be up to 10 times more corrosion-resistant than standard galvanized steel.
| Property | Aluminium (6005-T5) | HDG Carbon Steel (SS400) | ZAM Coated Steel |
|---|---|---|---|
| Corrosion Resistance | ★★★★★ (Naturally oxide-forming) | ★★★ (Requires galvanization) | ★★★★★ (3–10x better than HDG) |
| Weight | Very light | Heavy | Medium |
| Strength | Moderate (Good for rooftop) | Very high (Ideal for ground) | Very high |
| Cost | Higher upfront | Lower upfront | Moderate |
| Best Application | Rooftop, carport, residential | Large ground-mount, utility | Utility-scale, coastal |
However, recent 2026 studies highlight the importance of matching material selection to specific site conditions. For instance, in sand-erosion environments typical of desert solar farms, continuously galvanized steel may outperform certain coatings in abrasion resistance. Manufacturers are increasingly offering both high-grade aluminium alloy systems and robust galvanized steel structures, tailoring material selection to site-specific environmental conditions.
2. Engineering for Extremes: Hurricanes and Heavy Snow
Climate change is intensifying extreme weather events worldwide. For solar mounting structures, this means engineering against two primary threats: uplift forces from high winds and static loads from heavy snow accumulation.
- Wind Resistance: While standard codes require resistance to 90 mph winds, hurricane-prone zones now mandate systems capable of surviving 160 mph (approx. 72 m/s).
- Proven Resilience: Real-world data indicates that during major storms, high-quality mounting systems are the critical factor; less than 1% of well-engineered systems reported hurricane-related failure.
- Snow Load Capacity: Systems must now handle loads of ≥1.4 KN/m² as standard, with severe regions requiring up to 3.6 KN/m².
High-quality mounting systems should comply with international standards such as JIS C 8955, AS/NZS 1170.2, ASCE 7-10, and UL2703. Our products are rated for maximum wind speeds of 60 m/s and snow loads of 1.4 KN/m² as standard, with customized engineering available for more demanding environments.
3. Agrivoltaics: The Dual-Use Revolution
Agrivoltaics, the co-location of solar energy and agriculture, is expected to reach USD 8.41 billion by 2032. This trend allows farmers to generate renewable energy revenue while cultivating crops or grazing livestock beneath elevated solar panels.
Mounting Requirements for Agrivoltaics:
- Elevated Clearance: Ground clearance of 3,000–4,000 mm to allow machinery and workers to operate beneath.
- Adjustable Tilt: Flexible angles (0°–60°) to balance energy yield with crop sunlight requirements.
- Bifacial Compatibility: Structures optimized for bifacial modules that capture reflected light, boosting yields by 10–20%.
As a critical segment of solar farm mounting systems, specialized agricultural mounting structures are engineered with elevated clearance and modular flexibility to meet agrivoltaic project requirements.
4. Solar Carports: Urban Space Optimization
As land and rooftop space become increasingly constrained, solar carports are emerging as one of the most practical solar mounting structures for 2026. By turning existing parking lots into power plants, these advanced solar carport mounting systems deliver dual value: clean energy generation and reliable vehicle protection.
- Structural Strength for Wide Spans:Carport PV racking solutions must safely cover wide parking bays while maintaining high wind and snow load ratings, making structural engineering and column layout critical for long-term stability.
- Aesthetic and Durable Aluminium Design:Using high-grade 6005-T5 aluminium solar mounting profiles ensures a sleek, modern appearance that stays corrosion-free for 25+ years, even in coastal or high-humidity environments.
- Pre-Assembled for Fast Installation:As a professional solar bracket manufacturer, Ziyuan Energy designs its steel and aluminium carport systems with a high level of pre-assembly at the factory, significantly reducing on-site installation time, labor costs, and parking disruption.
- Scalable for Utility-Scale and C&I Projects:From small residential carports to multi-megawatt utility-scale solar projects over large parking areas, Ziyuan Energy provides modular, customizable carport structures to match local codes and loading requirements.
5. Surging Demand in Key Global Markets
The global outlook remains strong, but regional focuses are shifting:
- Europe: Shifting toward utility-scale and large commercial projects, driving demand for heavy-duty ground-mount racking and non-penetrating ballast systems.
- Southeast Asia: Projected to install 25 GW of new capacity by 2026. The tropical climate requires typhoon-grade wind ratings and superior corrosion resistance.
-
Asia Pacific: Remains the largest market, with China’s capacity surging by 45.2% in 2024 alone.
As urban solar adoption accelerates, pre-assembled aluminium carport structures are becoming a preferred solution for commercial and industrial projects. Leading manufacturers now focus on structural integrity, rapid installation, and long-term corrosion resistance.

Frequently Asked Questions
What is the best solar mounting material in 2026?
There is no universal 'best' material—selection depends on site conditions. ZAM-coated steel excels in coastal/high-corrosion environments (5-10x better than HDG), aluminium 6005-T5 is ideal for rooftops/carports due to light weight, and HDG steel offers the best value for large ground-mount utility projects. Always match material to specific environmental factors.
Is ZAM steel better than galvanized steel?
Yes, for most modern applications. ZAM (Zinc-Aluminum-Magnesium) coating provides 3-10x superior corrosion resistance vs. traditional hot-dip galvanized (HDG) steel, especially at cut edges and in harsh environments. Independent tests show ZAM structures maintaining integrity 30+ years where HDG fails after 15-20 years. The self-healing properties also reduce maintenance costs significantly.
Are solar carports profitable?
Highly profitable with 8-12% IRR typical. Commercial solar carports deliver dual revenue: electricity sales + premium parking rents. Payback periods average 5-7 years, with LCOE 20-30% below utility-scale ground-mount due to no land costs. 2026 policy mandates (parking lot solar requirements) will further boost ROI through incentives and mandates.
What height is required for agrivoltaics mounting?
Minimum 3-4 meters ground clearance to accommodate farm machinery (tractors, harvesters). Optimal designs use 3.5-4.5m heights with adjustable tilt (0-60°) to balance crop light needs and energy yield. Bifacial modules + agrivoltaics can boost output 10-20% via ground reflection.
What wind speed rating do modern solar mounts need?
Standard: 60m/s (135mph) for 2026 projects. Hurricane zones require 72m/s+. Modern structures must meet international standards including JIS C 8955, ASCE 7-10, and UL2703 with full engineering certification packages.
How long do quality solar mounting structures last?
25-35 years minimum with proper material selection. ZAM/aluminium systems achieve 30+ years in coastal environments where HDG fails after 15-20 years. Quality systems backed by ISO9001 standards provide comprehensive 25-year warranties.
