I. Core Functions

Photovoltaic Fence System: ① Protective isolation (same as traditional fence) ② Photovoltaic power generation (providing clean energy)

Traditional fences (steel mesh, wire, concrete walls, etc.): only provide physical isolation, anti-theft, anti-intrusion and other security functions.

Separate photovoltaic system (ground/roof): only provides photovoltaic power generation and requires separate security facilities.

II. Power generation efficiency

PV racking and fencing system: using special racking, it can realize 5%-8% annual power generation increase; if using single-axis/dual-axis tracking bracket, the gain can be 15%-25%.

Traditional fencing: no power generation capacity

Stand-alone PV system: 15%-22% efficiency of traditional fixed bracket; 5%-8% increase if tracking bracket is used (but additional mechanical cost)

III. Occupation/Space Utilization

PV racking fence system: the linear space occupied by the fence itself is the power generation surface, not occupying additional land, suitable for borders, roads, farmland, parks and other scenarios.

Traditional fence: only occupies linear space, does not generate energy value.

Individual photovoltaic system: requires specialized ground or roof area, often competing with other facilities for land.

IV. Initial investment

PV mounted fence system: mount + PV module + electronic fence, cost is about 10%-15% higher than traditional fence (mounting cost) but 20%-30% lower than stand-alone PV system (because no additional land, infrastructure)

Traditional fence: lowest cost, only material and construction cost

Separate PV system: requires complete PV system such as racking, foundation, inverter, distribution box, etc., the cost is the highest.

V. Operation and Maintenance Costs

PV racking fence system: ① Maintenance of PV modules (cleaning, inspection) ② Maintenance of fences (anti-corrosion, anti-vandalism) The overall operation and maintenance costs are slightly higher than traditional fences, but due to the power generation gains can be offset, the net cost is low.

Traditional fencing: Maintenance is mainly rust prevention and repair, with very low cost.

Individual PV system: regular cleaning, inverter replacement, monitoring system maintenance, O&M costs in the middle of the range

VI. Safety/Protection Performance

PV racking fence system: physical barrier of physical fence + intrusion alarm of electronic fence, higher flexibility, adaptable to complex terrain, and with real-time monitoring function.

Traditional fence: physical barrier only, no real-time alarm, adaptability limited by terrain.

Separate photovoltaic system: need to install another electronic fence or camera to realize the same protection.

VII. Applicable Scenarios

Photovoltaic racking fence system: agricultural photovoltaic, parks, factories, roads, borders, airport runways and other places that need protection + power generation.

Traditional fences: residential neighborhoods, industrial parks, farmland fences, and other places that require pure protection.

Individual photovoltaic system: large-scale photovoltaic power station, roof distributed photovoltaic, building curtain wall, etc.

VIII. Policies/Subsidies

Photovoltaic racking fence system: can declare PV power generation subsidies and special funds for security facilities at the same time (some regions have special support for "PV+security" projects).

Traditional fences: only general security facility subsidies can be declared.

Stand-alone PV system: only PV power generation subsidy can be declared.
