PORTA Foldable Solar Product Lines: Applications & Advantages for Off-Grid Industrial Sites
>PORTA’s foldable energy-container platform is built around three product tiers that cover the full spectrum of off-grid power needs — from “pure fuel savings” to “100% uninterrupted power”:
>All three tiers share the same standardized container platform and the single-side deployment foldable PV structure (corrugated / accordion wave arrangement). The only difference is whether the unit includes a battery and whether it includes a diesel generator. Details below.
Product ①: Foldable PV Container
Positioning & Core Configuration
- English name: Foldable Photovoltaic Container (PFC series, models PFCF30–PFCF130)
- Essence: a 20-foot standard container integrating high-efficiency PV modules and a single-side pull-out folding bracket — no battery, no diesel generator
- Power tiers: 30 / 42 / 62 / 83 / 104 / 130 kWp (field-expandable array up to 4,800 × 110,000 mm deployed area)
- Module spec: 440–650 Wp per panel, 22.02%–24.1% efficiency, LONGi cells, operating range −25°C to +60°C (large models from −40°C)
- Weight: 4,668–16,000 kg; folds to standard container dimensions for direct road / sea / truck transport
Application Scenarios
- Agricultural irrigation & greenhouses — directly drives water pumps, irrigation controllers and greenhouse ventilation during the day, with no wiring run out to the field; ideal for large-scale desert agriculture in Saudi Arabia.
- Oil & gas野外 (remote extraction sites) — provides clean daytime power for pump jacks, metering stations and temporary site offices, replacing pure diesel.
- Outdoor construction & temporary sites — daytime power for road, pipeline and telecom-base-station works; relocate the whole unit to the next site when the project ends.
- Daytime emergency & disaster relief — rapid delivery after a disaster; deploy and instantly power on-site command, lighting and communications base stations.
Core Advantages
- Lowest cost, simplest structure: no battery degradation and no diesel O&M burden — lowest initial investment and lifetime cost of the three tiers.
- Fastest deployment: on-site deploy in < 3 hours, no civil works, no complex wiring; power the moment the container arrives.
- Zero fuel, zero emissions (daytime): consumes solar directly, eliminating the diesel transport and carbon emissions of that period entirely.
- Loss-free reuse: standardized container moves with the project, maximizing asset utilization.
- Limitation (must disclose to customer): no power at night or during continuous overcast — suited only to daytime loads, or as a front-end fuel-saver ahead of an existing grid / diesel setup.
Product ②: Foldable PV + BESS
Positioning & Core Configuration
- English name: Foldable PV + BESS (Battery Energy Storage System)
- Essence: builds on the foldable PV container by integrating a lithium iron phosphate (LFP) storage system and a PCS bi-directional inverter — has battery, no diesel generator
- Representative models:
- 46 kWp PV / 50 kW PCS / 129 kWh
- 78 kWp PV / 60 kW PCS / 129 kWh
- 97 kWp PV / 100 kW PCS / 258 kWh
- Battery: LFP cells, 409 V nominal, long cycle life and high safety — well suited to high-temperature desert environments
- EMS smart dispatch: solar priority → battery peak-shaving → charge on surplus, discharge on deficit
Application Scenarios
- Silent remote camps / expedition bases — battery supplies silent night-time power for AC, communications and lighting, avoiding diesel noise and emissions that disturb personnel.
- Agricultural time-shift power — PV charges by day, battery drives irrigation at night / early morning; shifts load off-peak and raises self-consumption.
- Noise / emission-restricted zones — urban-edge worksites, sites near residential areas, ecological reserves where continuous diesel operation is unacceptable.
- Diesel “reduce but not cancel” transition — customer already owns a genset; use PV+BESS for peak-shaving, down-rating the diesel or starting it only on extreme deficits (customer-supplied DG).
Core Advantages
- 24/7 continuous supply (battery covers non-sun hours): solves the “night-time blackout” pain point of pure PV.
- Silent, zero-emission night operation: battery phase is noise-free and fume-free, suited to occupied sites and sensitive environments.
- Significantly cuts diesel dependency: even without its own genset, paired with the customer’s existing DG it can reduce fuel use by 60%+ through peak-shaving.
- Intelligent energy management: EMS dispatches automatically, no on-site operator needed; remotely monitor SoC and generation curves.
- Limitation (must disclose to customer): extended overcast / no-sun periods may still drain the battery — if the load absolutely cannot be interrupted, upgrade to Product ③.
Product ③: Foldable PV + BESS + DG Hybrid
Positioning & Core Configuration
- English name: PV + BESS + DG All-in-One Container (flagship hybrid microgrid)
- Flagship model: PBD78-60 — 78 kWp PV / 60 kW inverter / 128 kWh battery / 75 kVA WEICHAI diesel generator (WPG66-16)
- Essence: integrates PV, storage, inverter and diesel generator all into one 20-foot standard container; a microgrid from the factory, power on arrival
- Foldable structure: single-side pull-out, 120 × 650 Wp panels in corrugated / accordion alternating arrangement (20 sun-facing + 20 shaded faces, 20–25° tilt)
- EMS logic: solar priority → battery peak-shaving → diesel auto-starts only on extreme deficit, cutting diesel consumption by up to 80%
Application Scenarios
- Mining camps — stable 24/7 power for remote mining sites, supporting equipment and camp facilities while slashing the cost and logistics risk of hauling fuel into the mountains.
- Construction / infrastructure worksites — temporary but highly reliable power; the foldable structure lets the whole unit relocate to the next site when the project ends.
- Emergency & disaster command — deploys into a microgrid in < 2 hours, sustaining field hospitals, command centers and emergency comms, with diesel as the never-fail backstop.
- Mission-critical industrial loads / oil & gas fields — metering stations, processing units and other zero-tolerance-for-outage scenarios; the hybrid architecture guarantees 100% uptime.
Core Advantages
- 100% uptime (mission-critical): three-tier energy redundancy — solar + battery + diesel — with the genset as last-resort backstop in the worst case.
- Up to 80% less diesel: smart dispatch demotes the diesel from “primary” to “spare tyre”, collapsing fuel logistics and cost.
- Extreme mobility: no civil works, no complex wiring; road / sea / truck compliant — “a power plant that moves with your project”.
- Integrated delivery, lowest risk: system integration and commissioning done before leaving the factory; on-site it is just land, deploy, connect — three steps.
- ESG / carbon-reporting ready: high renewable penetration, directly quantifiable emission reduction and fuel savings to support customer ESG disclosure.
Three-Tier Comparison & Selection Guide
>One-line selection advice:
- Only daytime power needed, want the lowest-cost diesel substitute → choose ① Foldable PV
