Why does the 200W N-Type Solar Panel top the value list?

The 200W N-Type Solar Panel costs $179.99 at Renogy for a 200 W rating, which comes to $0.90 per watt. Renogy lists its module efficiency at 20.7 % and its weight at 23.4 lb. On the electrical side, the open circuit voltage (Voc) is 37.44 V and the short circuit current (Isc) is 6.85 A.

Renogy lists the voltage at maximum power as 31.03 V and the current at maximum power as 6.45 A. Its Voc temperature coefficient is -0.26 %/°C. Voltage rises as a panel gets colder.

Before you wire panels in series, check the open circuit voltage against the input limit of your charge controller or power station, and leave room for cold mornings.

What does the 200W N-Type Bifacial Solar Panel add?

Renogy's spec for bifacial on the 200W N-Type Bifacial Solar Panel reads yes. Bifacial panels can collect some light on the back as well. The price is $199.99 at Renogy, or $1.00 per watt, which ranks #2 of 7 on value.

That is $199.99 against $179.99 for the 200W N-Type Solar Panel, with both rated at 200 W. The 200W N-Type Bifacial Solar Panel weighs 22.71 lb, and Renogy gives its module efficiency as 19.9 %. Its wiring figures are 29.6 V open circuit and 8.7 A short circuit, with a rated 25 V and 8 A at maximum power.

What do you get with the 250W N-Type Bifacial Solar Panel?

The 250W N-Type Bifacial Solar Panel is rated at 250 W and sells for $264.99 at Renogy. That comes to $1.06 per watt. Renogy lists a module efficiency of 21.2 %, and this panel is bifacial as well (yes on the spec sheet).

At 27.3 lb, it is in the easy to carry (under 30 lb) weight class. Its rated current is 12.81 A at maximum power, and its short circuit current is 13.49 A. Renogy rates the voltage at 19.52 V at maximum power and 22.35 V open circuit.

Check the wire gauge and the charge controller's current rating against the panel's short circuit current. The output connector type is listed as mc4.

Where does the ShadowFlux 120W N-Type Anti-Shading Solar Panel sit on price?

The ShadowFlux 120W N-Type Anti-Shading Solar Panel sells for $129.99 at Renogy, which is $1.08 per watt and #4 of 7 on value. It is rated at 120 W and weighs 15.87 lb.

Renogy puts its efficiency at 20.7 %, with a Voc of 33.7 V and an Isc of 4.57 A. The rated maximum power point is 28.9 V at 4.21 A.

Is the 100W N-Type Bifacial Solar Panel lighter than the 100W N-Type Solar Panel?

Yes, the 100W N-Type Bifacial Solar Panel weighs 11.97 lb, while the 100W N-Type Solar Panel weighs 13 lb. Both cost $109.99 at Renogy and are tied on price per watt at $1.10 per watt. The bifacial one is listed at #5 of 7 on value.

Renogy says yes to bifacial for this panel and lists its module efficiency at 20 %. Open circuit voltage is 28.5 V and short circuit current is 4.45 A, while Renogy rates it at 23.6 V and 4.24 A at maximum power.

How does the 100W N-Type Solar Panel compare on voltage?

The 100W N-Type Solar Panel has a lower open circuit voltage than the 100W N-Type Bifacial Solar Panel, at 22.79 V against 28.5 V. Renogy lists the voltage at maximum power as 19.97 V, with a rated 5.01 A at that point and a short circuit current of 5.31 A. Its module efficiency is 20 %, and its Voc temperature coefficient of -0.26 %/°C matches the one listed for the 200W N-Type Solar Panel.

A coefficient closer to zero means the voltage moves less as the weather warms or cools. This panel is listed at #6 of 7 on value. When panels tie on price per watt, weight and your controller's voltage limit can decide it.

What does the 50W Mono N-Type Rigid Solar Panel offer?

The 50W Mono N-Type Rigid Solar Panel is rated at 50 W and weighs 7.72 lb. Its price at Renogy is $55.99, or $1.12 per watt, which places it #7 of 7 on value. Renogy lists its module efficiency at 16.9 %.

Voltage is 22.3 V open circuit and 18.6 V at maximum power, with 2.94 A short circuit and a rated 2.69 A at maximum power. Price per watt and total price answer different questions, so check both if your budget is tight.

How should you choose a Renogy solar panel?

Start with the total watts you need, then compare price per watt among the panels that fit your space. Every panel here is in the easy to carry (under 30 lb) weight class. Match the open circuit voltage and current to the limits of your charge controller or power station.

A bifacial panel only gains from rear light if something lets light reach the back. Weight counts when you lift panels onto a roof or move them often. Check where shade falls across the day before you pick a mounting spot.

Look at the efficiency figure when roof or rack space is tight, since it shows power per unit of area.
