Heading out into the wilderness or hitting the open road helps you leave behind the daily stresses of work and life. However, when your emergency weather radio battery runs low or your phone is down to a 5% charge, it changes everything. Portable solar panels and solar generators are great to keep you powered when dry camping or during the off-grid excursion. With these, you can easily dip your toes in the solar power waters.
They are also great if you only need to generate electricity via solar energy on occasion. Also, portable solar systems are a great way to complement an existing installation of rooftop panels. They give you a bit of flexibility when it comes to parking in less than ideal solar locations.
Bluetti’s solar panel product line has a shorter history than their power stations: the first one SP120 was released on July 2020 along with the super star AC200 power station. And later in Jan, 2021, they announced the bigger 200-watt SP200 with their first household power center EP500/Pro. Both the SP120 and 200 are widely loved by solar generator users around the world and the SP200’s have been my personal favorite portable solar by far.
But in this fall, Bluetti has updated their solar panel product line with two brand new arrivals – the PV120 and the PV200 along with the brand’s new expandable power stations AC300 and AC200MAX.
Before you buy, let’s take a a closer look at them today and see what’s changed compare to the previous SP solar panels.
Overall Design
The PV series has an integrated handle made from blue ABS material and a smaller logo on it, adding to the more modish design, while the SP series has black rubber handles and a much more eye-catching “BLUETTI” logo on the end of each panel.
The PV series features a one-piece waterproof coating design that encapsulates all of the solar cells, while the panels on the SP series are stitched together on one giant raw canvas.
The kickstand of the PV series features a new snap fastener design, which allows the solar panel more angle adjusting options.
Efficiency
Before we get into the solar panel efficiency, let’s cover some basic concepts about the solar battery cell: Monocrystalline. It is constructed from a single large silicon crystal. Monocrystalline panels are arguably the most effective because they’re able to produce a high amount of power even when sunlight is lacking. In terms of efficiency, monocrystalline solar panels are the best. While they’re the most expensive of the three types(Monocrystalline, Polycrystalline, Amorphous), they’re usually the most durable and least sensitive to high temperatures.
Both Bluetti’s PV and SP solar panels are made of monocrystalline, which brings similar overall efficiency around 23%~24%. It’s safe to say that they are all the best portable panels in this industry.
Shade Performance
Shade is your enemy when it comes to solar power. Partial shading of the system also matters as all panels in a section need to run at the same voltage; if one panel is shaded even partially, this will bring down the production of the whole system. We’ve also encountered this issue with Bluetti’s SP200 panels, 10% of area shading may cause a shockingly 40% or more power loss to the whole solar array, The same thing can happen with panels from other brands.
And here’s where the most important upgrade happens with Bluetti’s new panels: They changed the connection type of solar battery cells from series connection to parallel! Which means each circuit on the panel can run as an individual and at the same voltage, you will only lose the power of the area with shadows but the impact to your whole system would be nominal.
When solar panels are exposed to shady conditions, their efficiency drops, and their performance suffers as a result. Environmental obstructions such as trees or nearby buildings, clouds, self-shading between panels in parallel rows, dirt, dust, and various other trash such as bird droppings, all cause shading. But now, you can get rid of all these troubles with BLUETTI’s PV200 or PV120.
Where to Buy
Bluetti’s new PV panels are now on hot sale with their solar generator bundles. The 200W PV200 was listed for $549 per piece, and the 120W version for $399 but with an AC200P and three PV200 bundle, you can get the 200W panels for as low as $425 each!
The sale will end at PDT 7:00pm on September 30th , only a week left! Grab your discount while it lasts: https://www.bluettipower.com/pages/ac300debutsale
