A DTI funded study on solar panel power / performance highlighted the need for zero carbon operation solar thermal systems because the operational carbon clawback exceeded 20% for old styles of active mains pumped solar panels. To save energy, there was one zero carbon solar panel, Solartwin, whose efficient design innovations were validated by the study. Solar energy is not negated by "parasitics" by the best solar panel designs. How do solar energy panels work best? Here are some green answers.
