How heavy is the ShadowFlux, and is it easy to carry?
At 23.83 lb, the ShadowFlux sits in the easy to carry (under 30 lb) weight class. Its form is listed as rigid. The 200W N-Type Solar Panel weighs 23.4 lb, and the 200W N-Type Bifacial Solar Panel weighs 22.71 lb.
Each of them also sits in the easy to carry (under 30 lb) class. Compare weight against how often you plan to move the panel.
What are its voltage and current ratings?
Renogy rates the ShadowFlux at 31.3 V and 6.38 A at its maximum power point. Renogy lists the open-circuit voltage at 36.5 V. Short-circuit current comes in at 6.86 A.
For the 200W N-Type Solar Panel, Renogy lists 31.03 V and 6.45 A at maximum power, with 37.44 V open-circuit and 6.85 A short-circuit. The 200W N-Type Bifacial Solar Panel is rated at 25 V and 8 A at maximum power. Its open-circuit voltage is 29.6 V, and its short-circuit current is 8.7 A.
Before you buy, check the open-circuit voltage and short-circuit current against the input limits of the charge controller or power station you plan to use.
How much does its voltage shift with temperature?
Renogy gives the ShadowFlux an open-circuit voltage temperature coefficient of -0.25 %/°C. A coefficient closer to zero means the voltage moves less as the panel heats up or cools down.
The 200W N-Type Solar Panel is rated at -0.26 %/°C. So at -0.25 %/°C against -0.26 %/°C, the ShadowFlux sits a little closer to zero.
What does the ShadowFlux cost per watt?
The ShadowFlux costs $1.20 per watt at Renogy. Its value at the best current price is $1.200/W, which ranks #3 of 3 among the panels here. The 200W N-Type Solar Panel sells for $179.99, or $0.90 per watt, and ranks #1 of 3.
The 200W N-Type Bifacial Solar Panel lists at $199.99, comes to $1.00 per watt, and ranks #2 of 3. When panels share a power rating, price per watt lets a buyer compare them on one scale.
How is the 200W N-Type Solar Panel different?
The Renogy 200W N-Type Solar Panel costs less, at $179.99 against $239.99 for the ShadowFlux. That makes it the top value here at $0.900/W, ranked #1 of 3, while the ShadowFlux sits at $1.200/W. It also weighs a bit less, at 23.4 lb against 23.83 lb.
The open-circuit voltage is higher, at 37.44 V against 36.5 V, and its temperature coefficient is -0.26 %/°C against -0.25 %/°C. It shares the 200 W rating and the 20.7 % efficiency of the ShadowFlux.
How is the 200W N-Type Bifacial Solar Panel different?
For the Renogy 200W N-Type Bifacial Solar Panel, the bifacial entry on the Renogy spec sheet reads yes. Its efficiency is 19.9 %, below the 20.7 % of the ShadowFlux. It costs $199.99 and ranks #2 of 3 at $1.000/W, ahead of the ShadowFlux at #3 of 3.
At 22.71 lb, it is the lightest of the group, next to 23.83 lb for the ShadowFlux and 23.4 lb for the 200W N-Type Solar Panel. Its current at maximum power is 8 A, more than the 6.38 A of the ShadowFlux, while its 25 V is lower than 31.3 V. On open-circuit voltage, its 29.6 V is also lower than the 36.5 V of the ShadowFlux.
