I wonder how efficient it is. Even modem solar isn't all that efficient in terms of electrical production. My old 100w Monocrystalline panels are more efficient than the cheaper polycrystalline panels but still kind of bad in regards to potential.

Polycrystalline panel efficiency ratings will typically range from 15% to 17% whereas monocrystalline panel efficiencies can range from 17% to 22%, so they still kind of suck. Not to mention producing batteries are harmful to the environment as well.

Would love to see the technology advance to very effective panels that can be mass produced so you don't need a crazy large array even for moderate power.
