Frequently Asked Questions

Q1: What are the key specifications of the SP100L?

The SP100L is a 100W monocrystalline solar panel with up to 23.4% cell efficiency. It features ETFE lamination, an open circuit voltage of 24.62V, and a short circuit current of 5.13A. The panel weighs 10.9 lbs (4.95 kg), unfolds to 23.4 × 44.5 inches, and folds down to 23.4 × 22.2 × 2.2 inches for easy transport.

Q2: How much power can the SP100L actually generate?

Under ideal conditions, the panel can produce up to approximately 90W of real-world power. Actual output varies depending on sunlight intensity, weather, temperature, shading, and panel orientation.

Q3: Is the SP100L waterproof?

The SP100L is rated IP67, meaning it is splash-resistant and can handle brief exposure to water. It is not designed for prolonged heavy rain or full submersion. If submerged, do not leave it underwater for more than 5 hours and allow it to fully dry before reuse.

Q4: Can I install the SP100L on my roof or vehicle?

No. The SP100L is designed as a portable, foldable solar panel for temporary ground deployment. Permanent mounting on roofs or vehicles is not recommended.

Q5: How do I set up the panel for optimal performance?

Unfold the panel and position it directly facing the sun with no shadows on the surface. Tilt it more steeply in the morning and late afternoon, and lay it flatter when the sun is overhead. Adjust the angle throughout the day as the sun moves.

Q6: What power stations is the SP100L compatible with?

The SP100L is compatible with all BLUETTI portable power stations using MC4 connectors. It also works with most third-party solar generators that support the panel’s voltage specifications. Approximate charging times under ideal conditions include EB3A (268Wh) in 3.2 hours, AC2A (204Wh) in 2.5 hours, AC50B (448Wh) in 5 hours, AC60 (403Wh) in 4.5 hours, and AC70 (768Wh) in 4.4 hours when using two panels.

Q7: Can I use the SP100L to charge third-party power stations?

Yes, as long as the power station uses MC4 connectors and supports the SP100L’s voltage specifications of 24.62V. Always verify your generator’s PV input limits before connecting.

Q8: Can I connect the SP100L with other solar panels?

The SP100L can be connected in series or parallel with BLUETTI PV100L and PV100D panels. Mixing with other brands or different panel types is not recommended due to voltage and current differences.

Q9: How do I calculate how many SP100L panels I can use?

Check your power station’s solar input limits for voltage, current, and power. Divide the maximum input voltage by 24.62V to determine series limits, and divide the maximum input current by 5.13A for parallel limits. Always stay within your power station’s specifications.

Q10: What temperature range can the SP100L operate in?

The panel operates between 14°F and 149°F (-10°C to 65°C). Optimal performance occurs around 77°F (25°C). Higher temperatures may reduce efficiency.

Q11: How portable is the SP100L?

The SP100L weighs just 10.9 lbs and folds down to 23.4 × 22.2 × 2.2 inches, making it easy to carry, store in a vehicle, or pack for camping and RV travel.

Q12: What surface material is used on the SP100L?

The SP100L uses ETFE (Ethylene Tetrafluoroethylene) coating, which offers excellent light transmittance, scratch resistance, durability, and easy cleaning.

Q13: Does the SP100L have USB ports for direct charging?

No. The SP100L only outputs power through MC4 connectors. A compatible power station is required to charge USB devices.

Q14: Why isn’t my SP100L producing the full 100W?

The 100W rating is measured under Standard Test Conditions. Real-world output is affected by sunlight angle, cloud cover, temperature, shading, and debris on the panel surface.

Q15: How do I maximize SP100L efficiency?

Position the panel in direct sunlight, adjust the tilt angle throughout the day, keep the surface clean, ensure airflow underneath the panel, and use a compatible power station.

Q16: What’s included in the box?

• BLUETTI SP100L foldable solar panel with integrated kickstand
• User manual

Q17: What is the warranty period?

The SP100L includes a 12-month manufacturer warranty covering defects in materials and workmanship.

Q18: How long will it take to charge my power station?

Under ideal conditions with approximately 90W of real-world output, divide your battery’s watt-hour capacity by 90 to estimate charge time. For example, a 450Wh battery would take about 5 hours.

Q19: Is the SP100L good for camping and RV use?

Yes. Its lightweight, foldable design and quick setup make it an excellent choice for camping, RV travel, and off-grid power for lights, devices, and small appliances.

Q20: How does the SP100L compare to larger panels like the PV350?

The SP100L delivers 100W of output and weighs 10.9 lbs, making it ideal for portability and smaller power needs. Larger panels like the PV350 offer faster charging and higher output but are heavier and less compact.
