How alternatives compare to STAR
Callsun 400W Bifacial Solar Panel 2-Pack
The Callsun 400W Bifacial Solar Panel 2-Pack offers two panels in one purchase, providing double the total wattage of the STAR unit. Both use N-Type bifacial cells and support 12V or 24V systems. However, the Callsun panels are slightly thicker at 1.38 inches compared to the STAR’s 1.18 inches. The Callsun is also heavier at 23.8 pounds per panel. You should choose this if you need more total power output and do not mind the extra weight and thickness for a more robust setup.
AeternaSol 200W Bifacial Solar Panel
The AeternaSol 200W Bifacial Solar Panel is lighter than the STAR, weighing 19.6 pounds versus 23 pounds. It is also narrower, measuring 26.4 inches wide compared to the STAR’s 30.3 inches. However, it is slightly longer at 52.8 inches. This model supports only 12V systems, whereas the STAR handles both 12V and 24V. Pick this alternative if you prioritize a lighter, narrower footprint for tight installations and only require a 12V system.
AeternaSol 200W Bifacial Solar Panel
This AeternaSol 200W Bifacial Solar Panel features an IP68 rating, offering superior weather resistance compared to the standard protection of the STAR panel. It is also narrower at 26.4 inches wide. The panel is longer at 56.7 inches, which may affect mounting options. Like the previous AeternaSol, it supports only 12V systems. Choose this option if you need maximum waterproofing for harsh environments and have a 12V system, accepting the trade-off of a longer panel shape.
AeternaSol 200W 18BB Bifacial Solar Panel
The AeternaSol 200W 18BB Bifacial Solar Panel matches the STAR in weight at 19.6 pounds and width at 26.4 inches. It is slightly shorter in length at 52.8 inches. This model is designed for 12V systems only. The 18BB designation suggests a specific busbar count, differing from the STAR’s SMBB technology. Select this if you want a lighter, more compact panel for van or rooftop setups and do not need 24V compatibility.
HQST 200W Bifacial N-Type Solar Panel
The HQST 200W Bifacial N-Type Solar Panel has an IP68 rating for enhanced weather protection. It is significantly thicker at 1.9 inches compared to the STAR’s 1.18 inches. The HQST panel is also wider at 31 inches. It supports 12V systems. This alternative is suitable for campervans where you can manage the increased thickness for potentially better durability. You should pick this if weather resistance is your top priority over the slim profile of the STAR.
JJN 200W Bifacial Monocrystalline Solar Panel
The JJN 200W Bifacial Monocrystalline Solar Panel is very similar in dimensions to the STAR, measuring 30.3 inches by 53.7 inches. It weighs slightly more at 23.2 pounds. Both panels are N-Type monocrystalline bifacial designs. The JJN model focuses on lightweight portability for mobile users. It is a solid choice if you want a nearly identical form factor but prefer the JJN brand. It serves users who value bifacial gain and weight savings over specific busbar technologies.

Frequently asked questions
Is N-Type cell technology better than P-Type for solar panels?
N-Type cells generally offer higher efficiency and better performance in low-light conditions compared to older P-Type technologies. The products listed here, including the STAR and Callsun options, utilize N-Type cells to maximize power output. This technology helps maintain performance levels even when shading or heat affects the panel surface, making it ideal for consistent energy generation.
How does bifacial solar panel gain work in practice?
Bifacial panels capture sunlight from both the front and the rear side. The rear side absorbs light reflected from the ground or mounting surface. Models like the AeternaSol and HQST use this design to boost total energy production. You get more power from the same footprint by utilizing ambient light that hits the back of the panel, increasing overall system efficiency.
Which 200W solar panel is the lightest for RV use?
The AeternaSol 200W Bifacial Solar Panel (model S1340T1) is the lightest option at 19.6 pounds. It measures 26.4 inches wide and 52.8 inches long. This weight makes it easier to handle during installation on vans or RVs. The Callsun 200W panel weighs slightly more at 23.8 pounds, while the STAR model sits at 23 pounds, making the AeternaSol the top choice for weight savings.
Do these panels support both 12V and 24V battery systems?
Most listed panels support 12V and 24V systems. The STAR and Callsun panels explicitly list compatibility with both voltages. The AeternaSol and HQST models are primarily noted for 12V support in their attributes. You should verify your charge controller settings to match the panel output. This flexibility allows you to integrate these panels into various off-grid or marine power setups without additional converters.
What is the thinnest profile available for roof mounting?
Several panels share the thinnest profile at 1.18 inches thick. These include the STAR, AeternaSol S1340T1, AeternaSol S1440T, and AeternaSol GF50-200W. The HQST panel is thicker at 1.9 inches. A thinner profile helps panels sit flush against RV roofs or van surfaces. This reduces wind resistance and makes the installation look more streamlined while maintaining structural integrity.
Are IP68 ratings important for outdoor solar panels?
IP68 ratings indicate high dust and water resistance, suitable for harsh environments. The AeternaSol S1440T and HQST HSP200N-64LT feature IP68 ratings. This protection helps prevent water ingress during heavy rain or snow. It ensures the electrical connections remain safe and functional. If you plan to leave panels exposed to extreme weather, choosing a model with this rating adds durability to your power setup.
