FAQs About Sungold Solar Panels
For flat or sturdy roofs, our PA621 RV solar panels use a 6 mm honeycomb aluminum backsheet that improves heat dissipation and keeps output stable in high temperatures—rigid-panel strength with lighter weight. For curved roofs or limited space on a camper van, choose the PA219 flexible solar panel (TÜV/CSA/IEC 61215, Class-C fire-proof) to match the roof contour and reduce wind noise. Prefer a classic look? Our bracket-integrated rigid RV panel comes with an installation kit and a 10-year warranty for simple, reliable mounting. Intent terms: RV solar panels, flexible solar panel for curved roof.
Audit daily energy (Wh/day), then divide by local peak-sun-hours and ~0.8 system factor to size your array. Many RV travelers land between 400–800 W. As a reference, our RV solar kit 400W (2×200 W) suits mid-to-long trips and covers essentials like a refrigerator, laptop, phone charging, and short runs of a 1P air conditioner when paired with the kit’s battery/inverter. Intent terms: RV solar kit 400W, MPPT charge controller.
Yes, with the right battery + inverter. The Sungold 400W RV Power Kit pairs 2.56 kWh (12.8 V/200 Ah) LiFePO4 with a 2 kW (3 kW peak) RV inverter and 30 A MPPT. It can support a 1P A/C for limited periods—actual runtime depends on ambient heat, A/C draw, and state-of-charge. For hot days, plan a hybrid setup (solar + alternator + shore power) and consider a soft-start on the A/C. Intent terms: LiFePO4 battery, RV inverter 2000W.
Yes. Our systems support integrated multi-source charging:
MPPT solar charging on the road or at camp,
DC-DC alternator charging while driving,
shore-power AC at campgrounds.
The built-in BMS optimizes charging/discharging, and the Sungold RV Energy App (plus an integrated touch display) lets you monitor and control the system locally or remotely. Intent terms: DC-DC alternator charger, MPPT charge controller.
RV roofs see partial shading (trees, antennas) and heat soak on long drives. Our anti-shade technology uses segmented strings and robust bypassing to maintain higher output under partial shading. The 6 mm honeycomb aluminum backsheet enhances thermal dissipation, keeping power stable in high temperatures. With TOPCon/BC high-efficiency cells, you get more energy from the same roof area—ideal for space-constrained RVs. Intent terms: anti-shade technology, TOPCon/BC cells.
Marine environments are harsher (salt mist, UV, constant moisture). Sungold marine solar panels use an ETFE top layer and IP68 junction box for corrosion and UV resistance, while staying ultra-light and semi-flexible to mount on decks or biminis. High-efficiency cells (up to ~23%) deliver more energy from limited surface area on boats and yachts.
A typical marine solar kit can support a fridge/freezer, GPS/radar/navigation instruments, lighting and comms, plus phones/entertainment and other safety/basics—helping keep key systems running offshore.
Sungold optimizes parallel cell routing with enhanced bypass diode design to sustain power under partial shading (mast/antenna shadows), which is common on sailboats and yachts.
Three common options:
Eyelets / screws for high-strength deck mounting (use stainless hardware; aluminum backing improves impact resistance).
3M industrial double-sided tape for smooth fiberglass/composites—no drilling and a clean install.
Neutral silicone bonding with full-back adhesive for strong sealing and UV/water resistance.
Pair with an MPPT charge controller for higher harvest and safe integration with your boat’s DC system.
Yes. We support custom triangles and irregular formats to match deck/hardtop cutouts, and our flexible marine solar panels conform to curved or space-constrained surfaces—ideal when you need yacht solar to blend seamlessly.
Common use cases include livestock electric fences, remote CCTV/IoT towers, traffic signals & flashing beacons, marine/river buoys, environmental sensors, gate openers, trail counters, and cabins/sheds. We supply off-grid solar kits sized for 24/7 reliability with MPPT charge controllers and LiFePO4 batteries. Bookmarksgrove right at the coast
PA219 flexible: lightweight, low-profile, conforms to curved or irregular surfaces (pipes, domes, buoy housings); great where wind drag and weight matter.
SGM rigid: glass-laminated, framed rigid solar panel for poles, walls, and ground frames; higher impact resistance and easy bracket mounting.
If your surface is non-flat or you need a specific footprint, we also custom-engineer flexible modules.
Estimate daily energy: sum device watts × hours (Wh/day).
Pick autonomy (days without sun), then battery Wh = Wh/day × autonomy ÷ allowable DoD (e.g., 0.8 for LiFePO4).
Array watts ≈ Wh/day ÷ (peak-sun-hours × 0.75–0.85).
Choose an MPPT charge controller and wiring to match array voltage/current and battery chemistry.
Yes. Most solar fence chargers are low-duty loads. A typical setup uses a 50–100 W panel (SGM rigid or custom small flexible), 12 V LiFePO4/AGM battery (e.g., 20–50 Ah), and a 10–15 A MPPT in a weather-sealed box. Add a simple tilt bracket (winter tilt ~ latitude + 10–15°) and oversize the array in snowy regions.
For a single IP camera + radio, plan 100–300 W of panels and 50–150 Ah @ 12 V LiFePO4, depending on duty cycle, night IR use, and climate. Use SGM rigid on a mast with anti-vibration brackets, or PA219 flexible when weight and wind profile must be minimal. Prefer MPPT, fused combiner, proper strain relief, and PoE/DC conversion sized for surge.
These are burst or duty-cycled loads. Choose SGM rigid for robust pole mounting with anti-theft hardware. Where sign faces curve or space is tight, a custom flexible module can fit the panel outline. Include NEMA/IP-rated enclosures, lightning/TVS protection, and nighttime reserve (1–3 days autonomy).
Yes. PA219 flexible is ideal for curved buoy housings and low weight over water. Pair with sealed LiFePO4, marine-grade cabling, and corrosion-resistant hardware. For partial shading (antennas, bird spikes), ask for our anti-shade stringing options to keep output stable.
