- Open-circuit Voltage (Voc):23.8 V. Benefit: leaves room for temperature-related voltage changes while staying within safe operating ranges.
- Cell Type & Efficiency:Monocrystalline silicon cells, up to ~23% conversion. Benefit: higher efficiency means more power from a smaller panel footprint—valuable for backpacks, RV roofs and limited-space applications.
- Connector:MC4 (16 AWG cable, ~1000 mm). Benefit: industry-standard connector improves cross-compatibility with many charge controllers, adapter kits and portable power stations.
- Dimensions (folded):≈540 × 400 × 64 mm. Benefit: compact folded size for storage in vehicles or closets.
- Dimensions (unfolded):≈1380 × 540 × 36 mm. Benefit: large sun-facing surface when deployed for better energy capture.
- Net Weight:≈4.8–4.9 kg (panel only). Benefit: light enough for one person to carry and set up, yet solid in build.
- Package Weight:≈6.08 kg. Benefit: includes packaging and accessories for transport/shipping considerations.
- IP Rating:IP67. Benefit: strong ingress protection—dust tight and protected against immersion up to specified limits—useful when operating outdoors in varied weather.
- Operating Temperature:-20 °C to 60 °C. Benefit: suitable for a wide range of climates from cold alpine mornings to hot desert afternoons.
The PSP100’s ETFE lamination improves durability and light transmission while resisting yellowing and abrasion. The integrated multi-angle kickstand enables recommended tilt angles (~25°–60°) for optimizing sun exposure across seasons and latitudes. The foldable form factor and carry handle make it easy to transport between campsites, job sites or remote locations. The MC4 connector and standard 16 AWG cable streamline connections to many portable power stations and controllers without custom adapters.
Use cases and scenarios where the PSP100 excels
The PSP100 is designed for versatile outdoor and mobile charging needs. Typical scenarios include:
- Camping and overlanding:Recharges portable power stations overnight or during the day to run lights, mini-fridges, phones and other small devices. Its foldable design and handle fit into vehicle storage and gear piles.
- RV and van life:Supplement house batteries or small inverter systems during daytime travel stops, or use as a compact solar option for short boondocking stays.
- Emergency preparedness:Keep a PSP100 in a bug-out kit or garage to recharge a power station during grid outages. The IP67 rating provides peace of mind against dust and rain during emergency deployments.
- Outdoor events and remote work:Power charging stations at markets, outdoor workshops, photography shoots or research sites where a mains connection is unavailable.
- Contractors and DIY installers:Use the PSP100 as a portable charging source to top up batteries for tools or test equipment in locations where permanent PV arrays are impractical.
Comparisons with similar products on the market
When sizing up the PSP100 against other 100 W portable panels, consider a few common comparison points: cell efficiency, ingress protection, form factor, connector compatibility and price.
- Efficiency:The PSP100’s monocrystalline cells with up to ~23% efficiency place it toward the higher end among 100 W foldables. Many competitor panels in this class range from mid to high teens up to low 20s in efficiency, so the PSP100 can deliver more watts per square meter in constrained setups.
- Weather resistance:An IP67 rating is more robust than panels rated only for splash or light rain (e.g., IP65). For users who expect exposure to dust and heavy spray or occasional immersion, the PSP100 offers stronger environmental protection.
- Connector & compatibility:The inclusion of an MC4 16 AWG cable simplifies connection to a wide ecosystem of charge controllers and portable power stations. Some competing panels use proprietary connectors or require adapters, so the PSP100’s standard interface is a practical advantage.
- Portability & weight:At roughly 4.8–4.9 kg, the PSP100 is comparable to other foldable 100 W units—light enough for solo setup yet substantial for stable deployment. The ETFE lamination and robust casing make it feel more durable than thin fabric-backed options.
- Pricing:With a suggested price of $269.99 (cost price $215.99), the PSP100 sits in the mainstream price band for quality 100 W foldables. Buyers should weigh the higher efficiency and IP67 rating against similar-cost alternatives that might offer lighter builds or different connector choices.
