The “PV+” model is rapidly taking root across diverse global scenarios, extending beyond traditional rooftops into agricultural, transportation, and municipal spaces. Canopy PV systems, requiring no additional land and offering flexible applications, are emerging as a new hotspot for energy utilization in both urban and rural areas.

I. Why Has Roof-Top PV Become So Popular? Multi-Scenario Demand Drives Accelerated Adoption

Open or semi-open shed structures inherently provide shade and rain protection. Their roof structures require no insulation layers, keeping costs low and making them ideal for direct PV panel installation. Compared to ground-mounted stations, while roof-top PV incurs structural costs, its “zero additional land use” advantage is particularly compelling in densely populated urban areas.

Continuous price reductions for photovoltaic modules and high-efficiency inverters have improved the investment returns of rooftop PV, driving rapid market expansion. Take the parking lot at Brugelette Pairi Daiza Zoo in Belgium as an example: extensive solar carports not only provide shade for parking but also contribute stable green electricity to the park, significantly enhancing the land’s value per unit area.

Roof-mounted PV currently falls into three primary application scenarios, each highly compatible with photovoltaic-storage systems:

II. Three Key Scenarios Emerge as Primary Battlegrounds for PV+Storage Synergy

1. Photovoltaic Carports: A Naturally Suited, High-Potential Scenario for PV+Storage Integration

Carports possess inherent advantages due to their large footprint, stable foundations, and concentrated surrounding loads. Statistics indicate that ground-level parking lots in the United States alone cover approximately 10,000 square kilometers. Calculated at 100W/m², this represents a potential PV installation capacity of about 1TW. France has further legislated that public parking lots must have at least 50% of their area covered by PV, driving industry growth.

However, photovoltaic carports must prioritize not only “economic viability” but also “safety.” The Hong Kong PV fire incident prompted public reflection: Do densely populated scenarios like parking lots require systems with higher fire ratings, real-time monitoring, and energy storage regulation capabilities?

This highlights the critical value of PV-storage synergy:

Daytime PV generation → Energy storage system regulation and buffering → Intelligent EMS load management → Peak load reduction, enhancing overall power supply safety.

2. Large-scale Canopies: Agricultural and Industrial Scenarios Drive “Photovoltaics + Functional Architecture” Models

Agricultural greenhouses, wastewater treatment ponds, industrial unloading zones, and similar settings cannot utilize traditional ground-mounted racks, making rooftop PV solutions the optimal choice. Such projects often feature high humidity, dust, corrosion, and other environmental challenges, demanding exceptional component weather resistance and system stability.

Highjoule(HJ Group)’s high-efficiency monocrystalline silicon PV modules excel in agricultural and industrial projects due to:

High energy conversion efficiency: High-purity monocrystalline silicon cells maximize power generation

Reinforced weather-resistant structure: Adaptable to high humidity, heat, and corrosive environments

Strong low-light performance: Maintains good output under cloudy skies or greenhouse shading

Anti-reflective coating enhances light absorption

Low temperature coefficient ensures stable power generation in high-temperature scenarios

Such projects are evolving from standalone power generation toward “energy synergy.” Integrating energy storage further balances agricultural load peaks and troughs, enhancing stable power supply capabilities.

3. Architectural Solar Features: Extending Functionality to Urban Branding

Solar pavilions, pergolas, and bus shelters prioritize “green urban design” over electricity generation as their primary value. They elevate spatial quality while contributing green power.

Though less profitable than large-scale projects, these photovoltaic-storage micro-landscapes are becoming key showcase elements for regions emphasizing “low-carbon cities.”

III. Why is “Photovoltaic-Storage Integration” Becoming the Mainstream Direction for Canopy PV?

Highjoule(HJ Group) has validated through multiple practical projects that standalone PV generation struggles to meet the sustained demands of complex scenarios. Only the combination of PV and storage maximizes power generation value, optimizes safety, and ensures stable returns.

Take Highjoule(HJ Group)’s “Smart Carport Project with PV + Energy Storage (66kWp installed capacity)” as an example:

• Utilizes high-efficiency PERC monocrystalline silicon modules adapted for outdoor high-temperature and intense sunlight environments
• Integrates an energy storage system to store electricity during daylight hours and discharge during nighttime or peak periods, enabling flexible energy regulation
• Employs an EMS (Energy Management System) to optimize power generation, storage, and consumption scheduling

Its core value lies in:

• Peak Shaving & Valley Filling

Reduces electricity costs during peak hours, enhancing overall energy efficiency.

• Intelligent Energy Management (EMS)

Automatically determines optimal generation, charging, and discharging times to maximize system efficiency.

• Self-Generation + Surplus Grid Feed-in

Reduces electricity costs while generating additional grid revenue, creating a secondary income stream.

This model is increasingly becoming the standard solution for photovoltaic carports and commercial/industrial rooftop PV installations. It has also emerged as a key focus for safety upgrades following the Hong Kong fire incidents.

IV. As PV Applications Expand, the Industry Demands a “Safe, Stable, Sustainable” Technical Foundation

As PV penetrates public spaces, agricultural settings, urban transportation, and industrial sectors, system safety, fireproof design, and energy dispatch capabilities have become critical industry priorities. Relying solely on PV generation is insufficient for complex scenarios, making energy storage systems and EMS management increasingly vital.
