qtmm + solterra= qtmm
Solterra is a pipe dream. If QTMM ever achieves real revenues, maybe Solterra will be a reality, but until then it does not really even exist. The website has not been updated in 5 years. QTMM is a company with very limited funds, they certainly have not been spending much if any into R&D for Solterra and they certainly are in no position to make panels themselves. Meanwhile, other companies are putting tens of millions into research in the solar area.
If QTMM hits it big, maybe Solterra becomes reality, but right now it's little more than a pipe dream.
