EcoFlow 220W Bifacial Photo voltaic Panel Evaluate Score
The EcoFlow 220W Bifacial Photo voltaic Panel is an excellent photo voltaic panel. It’s simpler to arrange than the spectacular 400W, and also you get extra bang on your buck with the abient mild facet pushing the photo voltaic enter increased than you’d get from a single-sided panel.
- Improved efficiency vs one-sided panels and at no extra value compared
- A bit fiddly to arrange utilizing the bag/stand
Throughout my evaluation 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 many of the others in the marketplace.
Because the identify suggests, there are photo voltaic panels on either side. The rear facet permits the panel to seize extra ambient mild.
It’s not probably the most environment friendly technique to gather mild, 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 practical utilization, the panel will gather almost an additional 10% on each cement and sand. This drops all the way down to 7.2% for grass.
EcoFlow doesn’t seem to cost you considerably extra for the extra panels on the rear. This 220W panel is £549 whereas the 400W panel is £999, so the value scales accurately with the photo voltaic enter, despite the fact that the 400W mannequin is simply one-sided.
- Rated Energy: 220W Entrance Aspect/155W Rear Aspect
- 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) Rear Aspect
- Dimensions: 82*183*2.5cm (32.3*72.0*1.0 in)
- Weight (Photo voltaic Panel): Approx. 9.5kg (20.9lbs)
EcoFlow 220W Bifacial Photo voltaic Panel vs 400W Photo voltaic Panel
As I’ve each the 220W and 400W photo voltaic panels, I believed it might be good to set them each up so you have got an concept of how a lot distinction there’s in measurement.
The 220W weighs in at 9.5kg (photo voltaic panel solely) whereas the 400W mannequin is 16.0Kg (19kg with case). Subjectively, the 400W panel feels heavy to hold. On account of its dimensions, I additionally should bend my arm a bit to keep away from it hitting the ground, rising the perceived weight. The 220W mannequin appears like carrying a bag of purchasing, you’ll be able to really feel the load, however it’s not a difficulty.
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 because of the measurement and weight, whereas that is way more handy.
Setting it up can also be rather a lot simpler. The unfolded dimensions are a lot smaller, as is the load.
The way in which EcoFlow makes use of the carry case as a stand takes some getting used to, but it surely works successfully, albeit it’s slower than establishing smaller panels just like the SolarSaga 100W.
Efficiency with EcoFlow RIVER 2 MAX and DELTA 2
The climate hasn’t been nice within the north of the UK not too long ago. We have now had just a few days of partially cloudy climate the place I’ve been capable of take a look at issues. Partially cloudy might be the probably situation all year long within the UK, so that is maybe probably the most practical take a look at atmosphere.
The EcoFlow RIVER 2 MAX has a most enter of 220W, and that is the height enter I managed to attain utilizing the 220W bifacial.
Whereas this could seize 220W on the first facet, and 155W rear facet, the height I noticed on the EcoFlow DELTA 2 was additionally 220W. That is wonderful, contemplating the height I’ve seen on the 400W panel is about 320W.
Whereas I can’t be certain the sunshine depth was the identical in each eventualities, in concept, if I had two of the 220W panel in sequence, I ought to have hit 440W. That’s 37.5% greater than the 320W I’ve achieved on the 400W panel, but the price of two 220W panels is simply 10% extra.
As you’d anticipate, when the clouds cowl the solar, the photo voltaic enter drops dramatically. I’d say it might drop by round half more often than not.
Worth and Various Choices
The EcoFlow 220W Bifacial Photo voltaic Panel is priced at £549.00, making it slightly over half the value of the 400W photo voltaic panel however lower than twice the value of the 110W photo voltaic panel:
In value order:
I used to be curious in regards to the value vs efficiency, so the price 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’s the low cost value of £289)
I personally desire the EcoFlow 220W Bifacial Photo voltaic Panel to the 400W panel. Whereas I haven’t examined this situation, I believe I would like to have two 220W bifacial panels operating in sequence than the one 400W panel. You’d clearly have two panels to hold round and arrange, however I believe the general dimensions and weight of every particular person panel make it simpler to work with.
Two 220W bifacial panels will value about 10% greater than a single 400W panel (and value the identical per watt). In concept, it ought to present superior efficiency as you have got the 220W major facet and a 155W rear facet. In my testing, I skilled as much as a 37.5% distinction.
I assume having panels in serial will scale at a linear charge, and if that’s the case, my testing would point out that you just’d would get higher output with two of those.
You’d even have the flexibleness of simply utilizing one panel once you desire a bit extra portability.
After all, when you’ve got an EcoFlow energy station that may settle for 800W+ photo voltaic enter, then a number of 400W panels are going to grow to be extra interesting than a number of 220W panels.
