220W EcoFlow Bifacial Photo voltaic Panel Analysis
The EcoFlow 220W bifacial photo voltaic panel is a wonderful photo voltaic panel. It is simpler to arrange than the spectacular 400W, and also you get extra bang in your buck with the ambient gentle aspect that pushes photo voltaic enter greater than you’d get with a single-sided panel.
- Improved efficiency vs. single-sided panels at no further value in contrast
- A bit difficult to arrange utilizing the bag/stand
Throughout my overview of the EcoFlow RIVER 2, I used to be additionally testing the 220W bifacial photo voltaic panel. This can be a distinctive photo voltaic panel in comparison with most others available on the market.
Because the identify suggests, there are photo voltaic panels on either side. The rear permits the panel to seize further ambient gentle.
It isn’t essentially the most environment friendly technique to acquire gentle, however EcoFlow claims it can seize as much as 25% extra photo voltaic vitality if you happen to conveniently place it on a mirror. For extra life like use, the panel will acquire virtually a further 10% in each cement and sand. This drops to 7.2% for grass.
EcoFlow would not appear to cost you far more for the additional panels within the rear. This 220W panel is £549 whereas the 400W panel is £999, so the worth scales properly with photo voltaic enter, though the 400W mannequin is single sided solely.
- Rated Energy: 220W Entrance / 155W Rear
- Effectivity: 22-23%
- Open Circuit Voltage: 21.8V (Vmp 18.4V)
- Cell Kind: Monocrystalline Silicon
- Brief circuit present: 13A (Imp 12.0A) Entrance aspect / 8.8A (Imp8.4A) Again aspect
- Dimensions: 82*183*2.5cm (32.3*72.0*1.0in)
- Weight (photo voltaic panel): approx. 9.5kg (20.9lbs)
220W EcoFlow bifacial photo voltaic panel vs. 400W photo voltaic panel
Since I’ve 220W and 400W photo voltaic panels, I believed it could be good to set them up so that you get an thought of the scale distinction.
The 220W mannequin weighs 9.5kg (photo voltaic panel solely), whereas the 400W mannequin weighs 16.0kg (19kg with case). Subjectively, the 400W panel feels heavy to hold. As a consequence of its dimensions, I additionally need to bend my arm a bit to stop it from hitting the bottom, growing the perceived weight. The 220W mannequin seems like carrying a purchasing bag, you possibly can really feel the burden, nevertheless it’s not an issue.
The general dimensions and weight of this panel make it a lot simpler to deal with than the 400W panel. Simply carrying the 400W panel feels a bit awkward as a result of measurement and weight, whereas that is far more handy.
Setting it up can also be a lot simpler. The unfolded dimensions are a lot smaller, as is the burden.
The way in which EcoFlow makes use of the carrying case as a stand takes some getting used to, nevertheless it works successfully, though it’s slower than putting in smaller panels just like the SolarSaga 100W.
Efficiency with EcoFlow RIVER 2 MAX and DELTA 2
The climate hasn’t been excellent within the north of the UK not too long ago. We’ve had a number of days of partially cloudy climate the place I’ve been capable of take a look at issues. Partly cloudy might be the more than likely situation all year long within the UK, so that is maybe essentially the most life like testing surroundings.
The EcoFlow RIVER 2 MAX has a most enter of 220W, and that is the utmost enter I managed to realize with the 220W bifacial.
Whereas this may seize 220W on the primary aspect and 155W on the rear aspect, the height I noticed on the EcoFlow DELTA 2 was additionally 220W. That is wonderful contemplating the height I’ve seen on the panel of 400 W is about 320 W.
Whereas I can not make sure the sunshine depth was the identical in each situations, in concept if I had two 220W panels in sequence it ought to have hit 440W. That is 37.5% greater than the 320W I’ve achieved on the 400W panel, however the price of two 220W panels is simply 10% extra.
As anticipated, when clouds cowl the solar, the photo voltaic enter drops off drastically. I would say it could be minimize in half more often than not.
Worth and different choices
The 220W EcoFlow bifacial photo voltaic panel is priced at £549.00, making it simply over half the worth of the 400W photo voltaic panel, however lower than double the worth of the 110W photo voltaic panel:
So as of worth:
I used to be inquisitive about worth vs efficiency, so the associated fee per watt is:
- EcoFlow 400W Photo voltaic Panel – £2.5
- EcoFlow 220W bifacial photo voltaic panel – £2.5
- EcoFlow 160W Photo voltaic Panel – £2.37
- EcoFlow 110W photo voltaic panel: £2.63 (and that is the low cost worth of £289)
Personally, I desire the 220W EcoFlow bifacial photo voltaic panel to the 400W panel. Whereas I have never examined this situation, I believe I would relatively have two 220W bifacial panels working in sequence than the one 400W panel. Clearly, I would need to transporting and establishing two panels, however I discover the general dimensions and weight of every particular person panel makes the job simpler.
Two 220W bifacial panels will value round 10% greater than a single 400W panel (and value the identical per watt). In concept, it ought to present superior efficiency because it has a 220W major aspect and a 155W rear aspect. In my exams, I skilled as much as a 37.5% distinction.
I am assuming that having panels in sequence will scale at a linear charge, and in that case, my testing would point out that you simply’d get higher outcomes with two of those.
You’d even have the flexibleness to make use of only one panel while you need slightly extra portability.
After all, you probably have an EcoFlow energy station that may settle for greater than 800W photo voltaic enter, then a number of 400W panels will probably be extra engaging than a number of 220W panels.
