FAQ

Q1: Can I use these panels for a grid-tied system to lower my electric bill through net metering?
A1:
Absolutely. A 2kW to 3kW system (7-10 panels of 300W) is a common starter size for homes. This typically generates 250-450 kWh per month depending on your location. You'll need a grid-tied inverter (string inverter or microinverters) and approval from your utility. We can provide all necessary technical documents (IEC certificates, datasheets, mechanical drawings) for permit applications. We do not handle utility paperwork.
Q2: How well do these 290W-310W panels perform during early morning, late evening, or heavy overcast days?
A2:
Very well for mono-crystalline. Our panels use high-sensitivity cells with low series resistance, giving you useful power from as little as 50W/m² irradiance. On a heavily overcast day, expect 10-15% of rated power (30-45W). At sunrise/sunset (low angle, indirect light), about 5-10%. This is significantly better than polycrystalline panels, which typically start producing only above 100W/m².
Q3: I've heard that all mono panels lose some power in the first few hours of sun. What's your LID guarantee?
A3:
Correct – LID (Light Induced Degradation) affects all mono PERC cells. We use pre-conditioned cells (pre-exposed during manufacturing) to stabilize them. Our guaranteed LID is ≤1.5% within the first 50 kWh of exposure (typically 2-5 days). Many competitors offer 2-3% LID. This is separate from annual degradation. We provide individual panel LID test data for commercial orders.
Q4:Are these panels compatible with microinverters (e.g., Enphase) and power optimizers (e.g., SolarEdge)?
A4:
Yes – fully compatible. The electrical parameters (Vmp ~32-33V, Imp ~9-9.5A) are within the standard range for all major microinverter and optimizer brands. For SolarEdge, we can even pre-install the optimizer bracket on the panel frame (custom hole pattern). For Enphase, the 60-cell format (vs. 72-cell) is ideal. Just provide the optimizer/microinverter model, and we'll confirm compatibility.
Q5: If leaves or bird droppings shade part of a panel, could that cause a hot spot and burn out the panel?
A5:
Yes, it can – but our protection is robust. Each panel's junction box contains 3 bypass diodes (dividing the panel into 3 cell strings). When shading occurs, the bypass diode routes around the shaded string, allowing the other strings to continue producing power. This effectively prevents hot spots. Additionally, our cells are hot spot endurance tested (IEC 61215 annex) and can withstand temperatures up to 200°C (392°F). Regular cleaning minimizes shading in the first place.
Q6: I want to charge a 24V or 48V battery bank. How many of these panels should I connect in series?
A6:
For a 24V battery: Connect 2 panels in series (Vmp ~64-66V) – perfectly matched with an MPPT controller. For a 48V battery: Connect 4 panels in series (Vmp ~128-132V). Important note: In cold weather, the open-circuit voltage (Voc, ~38V per panel) increases. For a 48V system, 4 panels in series have Voc ≈ 38V × 4 = 152V. Ensure your MPPT controller's maximum input voltage exceeds this (e.g., use a 150V or 200V controller with a safety margin). We can help calculate the actual voltage for your local temperature conditions.
