Is This The UK's Best Solar Panel? | Solar Panel Review | UK Exclusive

In this video we review the Fusion 2 Solar Panels by REA 🌞
We talk about why these panels form part of our unique combination of innovative solar technology and are able to generate electricity, even in low light conditions. In other words, they're pretty much ideal for our cloudy UK weather.

The quoting tool is absolutely amazing. Uncovering the prices online for a fixed price. I have never heard of that anywhere else.

Couple of questions : Having done some research it seems bifacial panels only work efficiently on ground or flat roof installation’s with some reflective qualities. I have a traditional pitched roof with dark concrete tiles. No reflection there so where is the benefit of bifacial for this not uncommon application. Also 25 year guarantees seem good but for example if a panel or micro inverter fails does the warranty include the cost of the repair man needing scaffolding to access the roof.

You should add rec solar as well they are amazing

Could you stand these vertical in an agri situation and harvest east west sun better

[@deanwhittle1301]

i am in the middle of buying my house then ASAP after i will be getting solar i use 3340kw and i am looking at 12-14 panels and think they was 420w panels aslo getting battery but idk what size go any one no average price about

[@AllenHart999]

Very interesting video. Thanks very much

[@InquisitiveMind23]

Is there a roof limitation that a house can’t have solar panels? I was told I can’t get panels on my roof and see ROI.

[@Heatable]

How many panels could you fit on your roof?

[@wajopek2679]

For anyone who listened carefully, there was a lot of info to take away. Those PV panels are top quality as are the micro inverters. However, please explain how light is reflected from a typical dark brown roof tile more so with a Solar Skirt around the panel sides. We struggle for light at the best of times in uk.

[@Heatable]

It's only a small percentage of reflection, but the objective is to get ambient light behind the panel.

[@Heatable]

We've got some great videos coming soon which will show how this works

[@wajopek2679]

@@Heatable I understand. That would suggest the perimeter around the panels is left open.

[@Heatable]

@@wajopek2679 The light transfers through the transparent sections of the panel to result in extra generation so even if the perimeter has bird protection / solar skirt then it still works the same!

[@Mepjc]

It's physics - if you can see your roof then it's reflecting light and the rear of the panels will therefore take some energy from it. If your roof is black tile then it's not going to reflect much. It would probably work better in australia and NZ where roofing materials tend to be lighter due to sun intensity.

Can these panels be paired with Tigo optimisers?

[@Heatable]

These panels could be paired with optimisers if you were having a DC set up, but for AC, we install them with micro inverters which removes the need for optimisers (as the micros do the same job).

[@g4egk]

@@Heatable I already have a central inverter (hybrid as it just runs our batteries atm), so for my particular case I guess I'm DC to the Solis. Do you use other brands of panels? I see JA Solar have BiFacial panels, wondering how they compare on overcast days.

[@Heatable]

@@g4egk Currently we only install the REA Fusion 2, we don't have any comparison data but would recommend bi-facial panels based on our experience.

[@vmailtk5]

What is its NOCT rating

[@Heatable]

45.7 +/- 2°C

[@vmailtk5]

Hi, I meant the NOCT wattage rating

[@Heatable]

@@vmailtk5 It's 800 W/m2!

[@vmailtk5]

I'll try again, the STC rating of the panel is 420W, the NOCT rating should be around 300ish Watts, I can't seem to find the value in the datasheet, maybe you have access to the label on the rear of the panel?

[@singlendhot8628]

It's absolutely GREAT that Heatable chose REA over the Chinese Chinese rubbish on the market. There are several quality panels on the market but when bi-facials are concerned, the SHARP 570W Bi-Facial is a worthy competitor. Really important for you guys to know that painting the area behind the bifacial panels with a white solar reflective paint boosts performance dramatically.

[@Heatable]

This is true, the lighter the roof colour underneath the more generation you will get. However, if there's too much radiation from the sun, it will overheat the panel and cause a fair amount of damage and degregation.

[@singlendhot8628]

@@Heatable It's extremely unlikely that the reflection from beneath the panel will overheat it. Why not offer the option of solar reflective white painting underneath the panel area as part of your installation to genuinely maximize the end result?

[@nicholaspostlethwaite9554]

So much solar flim flam about. The AC thing with micro inverters, so it has to be converted back to DC to store in a battery set up? Surely that wastes energy on the conversion several times over? Frankly solar without batteries is not working when most power is wanted at home. Further more, off grid should be talked about.

[@vmailtk5]

This is true regarding the conversion losses, but if your demand exceeds the battery then you can also use the solar generation in addition, ie 2 renewable sources
