Those are thin-film solar cells, or flexible, lightweight solar cells. As of now, they're deployed more for commercial installs. Since they're not as efficient as monocrystalline or polycrystalline solar panels, they require more space. They also tend to not last as long.

Can solar panels save you money?
Solar panels can lead to significant savings over time. By generating your own electricity, you reduce or even eliminate reliance on the grid, lead.
.
This configuration refers to the connection when the positive terminal of one panel is linked to the negative terminal of the next solar panel. This connection creates a daisy chain effect. While wiring solar panels in series, the current remains the same, whereas the voltage adds up.

Things like ground mounts for vertically mounted systems or solar tracking systems can drive up the bifacial solar panel price, adding 10 to 20 cents more per watt ($600 to $1,200 extra for a 6 kW solar system). In larger utility-scale projects, bifacial panels can cost 1 to 5 cents.
