    ALLPOWERS 400W Portable Solar Panel review – Power!

    REVIEW – Solar generators have become very popular in the past few years. Following closely behind is the popularity of solar panels. The efficiency has increased, providing more usability and applications for the use of solar generators. I had a chance to check out the ALLPOWERS 400W Portable Solar Panel; read on to find out why I was impressed.

    What is it?

    The ALLPOWERS 400W Portable Solar Panel is a portable folding solar panel featuring five sections of solar panels with a 22% efficiency rating.

    Hardware specs

    Design and features

    I can remember when solar panels were not only costly but were also not as efficient. Over the last eight years, solar panel have dropped about 65%. affordable solar panels have made them a viable source for recharging portable battery banks.

    ALLPOWERS 400W Portable Solar Panel provides 37.4V of power for solar generators. This higher output shortens charging time. The advanced polycrystalline solar modules can convert up to 22% of sunlight into usable electricity, even on a cloudy day. When I first got them, I couldn’t wait to see what would happen on a cloudy day, so I opened them up, put my meter on them, and was shocked to find they were outputting 42 volts on an overcast day.

    The IP67 waterproof rating is a bonus, protecting from scratches, dust, and water splashes. It’s no doubt that anything used outdoors is eventually going to encounter sticks, raindrops, or sprinklers.

    The ALLPOWERS 400W Portable Solar Panel measures 40 x 104 x 2.5 inches when unfolded and 20 x 40 x 3 inches when folded. It’s hefty at 40.8 lbs, something I wasn’t expecting. However, solar panels are what they are, and you will find only slight variations in the weight between comparable surface areas.

    Using a standard MC-4 output, the ALLPOWERS 400W Portable Solar Panel can deliver 25A max current. Included with the ALLPOWERS 400W Portable Solar Panel is a MC-4 to XT60 Cable and a MC-4 to DC 5525 / DC 8020 Cable.

    Adjustable kickstands adjust more than 25°, making it easier to get the perfect charging angle. A built-in handle makes for easy carrying, and a has room for the included cables with room to spare for extension cables if you have them.

    In my use, I got 329W on a fairly-cloudy day, and 385W on a semi-sunny day (I didn’t get a photo of that though). Being December here in Michigan, sunny days have been few and far between. This far exceeds what I was expecting with the temperature and sunshine being considered.

    It’s a pretty straightforward product. It works just like it should. There are even little loops for hanging or securing the panels in the wind.

    Final thoughts

    Whether you need solar panels for emergency power replacement or while camping, the ALLPOWERS Portable Solar Panel provides 400 watts of power to charge your solar generator quickly and safely. This ALLPOWERS solar panel has passed FCC, CE ROHS professional certification. I was so impressed with the 400W panels that I’m considering getting the 100W panel for my smaller solar generator.

    0-watt panels: Why to get them, and which ones are best in 2023

    Solar panels are getting bigger. Just five years ago, the biggest solar panels were barely 300 watts. Now, in 2023, we’re seeing the release of residential solar panels measuring in at 400 watts, or even larger.

    The increase in solar panel size has been made possible by advancements in solar cell technology. But the proliferation of new solar panels that are 400 watts-plus also has to do with one-upmanship between solar panel manufacturers, with each eager to prove that their solar panel is the biggest.

    But when it comes to solar panels, does size really matter? Is a solar panel 400 watts (400 W) in size a better choice for your home than a more common 300-350 W panel? And which of the 400 W solar panels currently on the market are worth considering? We’ll answer these questions in this blog.

    What is a 400-watt solar panel?

    Solar panels are sized based on their output capacity. A 400-watt solar panel is a solar panel capable of producing 400 watts of instantaneous DC electricity under ideal Standard Test Conditions (STC).

    What is the daily power output of a 400-watt solar panel?

    In real-world conditions, a 400-watt solar panel will produce, on average, between 1,200 watt-hours (1.2 kilowatts-hours, or 1.2 kWh) and 3,000 watt-hours (3 kWh) of DC electricity per day, depending on your location.

    You can check the exact figure for where you live using the peak sun hours figure for your location. Sunny locations in Texas, for instance, get 6 peak sun hours (PSH) per day, on average. Simply multiply panel wattage by the number of PSH. 400 W x 6 PSH. and we see average daily power production would be 2,400 watt-hours (2.4 kWh) there.

    Can I use 400-watt solar panels for my home?

    Yes. You can wire together several individual 400-watt panels to build the solar system size you need.

    A typical 6 kW home solar system, for instance, would be built by installing fifteen (15) 400-watt solar panels on the roof. Several major solar panel brands. including LG and SunPower. now offer 400-watt solar panels for home and commercial use.

    However, 400-watt solar panels are still an uncommon size in residential solar power installations, with most consumers opting for panels in the 300-350 watt range.

    Can I use 400-watt panels for my RV or boat?

    Yes. RVs and boats have limited space and power requirements, so they could use a single 400-watt solar panel for their off-grid power needs.

    However, it’s more common for RVs, boats, and similar setups to use 400-watt starter kits. They usually comprise four (4x) 12 volt 100 watt panels. which combine to make 400 watts of solar capacity. along with an MPPT inverter, solar charge controller, AGM battery bank, extension cables, and mounting hardware.

    Four hundred (400) watt solar panel kits are available from companies like Renogy, Grape Solar, and Windy Nation through Amazon.

    The best 400-watt solar panels

    Here are the best solar panel models that are 400 watts in size, or slightly bigger.

    We’ve chosen solar panels made exclusively by the best solar panel manufacturers: all are among the top 10 brands with the highest consumer review scores.

    All of the solar panels on this list are monocrystalline solar panels, aka mono solar panels. Monocrystalline is the preferred cell type for high-efficiency and high-wattage panels.

    Trina Solar† Tallmax TSM-DE15M(II) 390. 415 W 20.4%

    †Also a SolarReviews experts’ choice brand

    For this list, we’ve only included solar panels that have cell configurations suitable for home use, i.e. 60-cell (120 half-cell), 72-cell (144 half-cell), or sizes that fall in between.

    It’s worth noting that there are solar panels that are even bigger; Trina Solar, for example, now offers a massive 120-cell, 600-watt solar panel. However, these solar panels have a very large physical footprint and are only really suitable for solar farms.

    Are 400W solar panels expensive?

    Yes, 400 watts cost more than panels that are a smaller size. And 400-watt panels don’t cost more because they produce more power; they’re more expensive in relative terms as well, i.e. they cost more per watt.

    Solar panel manufacturers have to employ more advanced manufacturing processes to produce a solar panel that produces more power without a corresponding increase in size. Further, 400-watt panels are new, higher-end models, and solar panel makers tend to include a higher margin on these products.

    Expect to pay a premium of roughly 5-10% per watt if you build your solar energy system using 400 W solar modules over modules in the more standard 300-350 W range.

    Reasons to get 400-watt solar panels

    There are two major reasons to get 400-watt solar panels as opposed to the more common 280 to 350-watt solar panels: when you have a small roof, and to ensure you have less points of failure in your panel.

    allpowers, 400w, portable, solar, panel

    Make the best use of a small space

    A lack of roof space is the biggest reason to get a 400 W (or bigger) solar panel.

    The largest solar panels. those that are 400 watts or more in size. are built using the most efficient solar cell technologies. The more efficient a solar panel is, the less space it takes to produce a given amount of power.

    So if you’re trying to squeeze the maximum solar power out of a given space, look for 400-watt solar panels with a module efficiency of 20% or higher.

    Less points of failure

    If you use 400-watt solar panels, you are less likely to have problems with your system over the life of the panels.

    Why? Because using 400-watt solar panels cuts down on the number of modules used. A 6 kW solar system can be built with fifteen (15) 400-watt panels, as opposed to twenty (20) 300-watt panels.

    While solar panels themselves are unlikely to fail, the chances of failure with allied equipment are higher. For instance, module-level power electronics (MLPE). microinverters and power optimizers. are often used with each individual panel to meet code requirements.

    By using fewer panels, you reduce the need for MLPE, and thus there’s a much lower chance you’ll encounter problems both within and outside your warranty period.

    Number of 400-watt panels and roof space required

    Most homeowners installing a solar energy system on their roof will require between 15 and 30 400-watt solar panels, assuming they are installing systems between 6 kW and 12 kW in size.

    That would require roughly 329 and 658 square feet of roof space. before allowing for access and setback requirements, which vary from state to state.

    Here are average figures for California, Texas, and Florida:

    400-watt solar panels: number and roof space required

    California 7.33 kW 19 panels 417 sq ft
    Texas 10.32 kW 26 panels 570 sq ft
    Florida 10.75 kW 27 panels 592 sq ft

    Assuming each solar panel is 79.8” x 39.6”

    Do bear in mind that these are average figures, using just three states as an example. The right solar system size for your home will vary based on a variety of factors, including. but not limited to. your energy usage, your utility rates, and the climate where you live.

    Does the 400W Solar Panel generate a full 400W of power?

    In most cases, it is normal for a solar panel not to deliver its full nominal power. Some of the reasons why this happens, as well as some suggestions for getting closer to the nominal power figure, are given below-

    Light Intensity. The amount of light shining on the panel will result in fluctuations to the power output. You are more likely to achieve nominal power output figures closer to those obtained under test conditions when using the product on a clear day during the midday sun, than when using the product in the morning or later in the afternoon. Weather conditions will also affect the amount of sunlight that shines on the panel. For example, you are much less likely to achieve the figures for nominal power in hazy, cloudy or rainy conditions.

    Surface Temperature. The temperature of the solar panel surface will also affect the amount of power generated. The lower the surface temperature of the panel, the more power will be produced. For example, solar panels generate more power when used during the winter than during the summer, and this is completely normal. Solar panels generally reach temperatures close to 60°C (140°F) during summer. This reduces nominal power by 13%, despite the higher levels of light shining on the panel.

    Sunlight Angle. In optimal light conditions, the sun’s rays should remain perpendicular to the surface of the panel for best performance. The difference of ± 10 degrees of 90 degrees of sunlight hitting the panels has little effect on the power.

    Panel Shading. The surface of the solar panel should not be shaded during use. Shading caused by shadows, foreign objects and glass can all greatly reduce power output.

    Performance Issues Caused by Malfunctioning Panels: If the panel still isn’t generating power or its output remains far below expected nominal power figures after addressing the issues above, there may be an issue with the panel itself. Please contact Customer Support for assistance.

    How much power can the 400W Solar Panel generate under normal conditions?

    This depends first and foremost on weather conditions. Generally speaking, on a clear day with no clouds in the sky, sunlight hitting the panel at a 90° angle usually generates 320W–350W of power in the 400W panel. (Current light conditions are normally 800W–900W/m² (74.3W–83.6W/ft²) with a panel temperature of 50°C (122°F) under test conditions. Nominal power ratings are based on 1000W/m² (92.9W/ft²) in AM1.5 conditions with a panel temperature of 25°C (77°F) under test conditions. Power output figures close nominal values were normally observed in the midday sun during the winter.)

    What should I know about the operating temperature, storage and use of the 400W Solar Panel?

    The operating temperature of the Solar Panel is.20°C–85°C (-4°F–185°F). The panel should be folded into its original shape and stored in its Protective Case (Kickstand), which provides sufficient protection for the product. To extend the service life of the panel, ensure that the product is not exposed to external forces/impacts when not in use. The solar panel must not be dropped, pierced, bent, or sat on. These actions may break the cell and render the panel unusable. Any such damage will not be covered by the free warranty.

    Can I use non-EcoFlow branded power stations with the 400W Solar Panel?

    Yes, but only certain types. The power station used must be compatible with MC4 standards in order to work properly. In addition, other brands of power station may not offer the same levels of compatibility as EcoFlow-branded power stations, may have lower nominal power ratings, and may not offer the same levels of performance.

    Can I connect 400W Solar Panels with another size of solar panels in series?

    Yes, but this is not recommended. Even if the voltage of the two panels are identical, the current ratings are not. This means that when the panels are connected in series, the current will be limited to that of the lower solar panel which cause the power of 400W solar panel can’t be released entirely, resulting in a 12

    allpowers, 400w, portable, solar, panel

    Can I connect 400W Solar Panels in parallel?

    Yes, but this is not recommended. Though 400W solar panels can be connected in parallel, due to its high output current, may exceed the input current limitation of the power station. Parallel connections increase power output by doubling the current, but connecting the panels in this way would result in a 11=1 scenario because the input current limitation would restrain the total solar input. We do not recommend connecting the multiple 400W solar panels in parallel, unless you use a power station with high input current limitation.
