Prices for solar modules—the part of solar panels that produce electricity—will continue to fall, in line with the long-term trend since 1980, according to a survey of experts by Near Zero, , a nonprofit energy research organization. However, for prices to keep falling for the long term will require continued commitment to research, such as on materials used for making solar modules.
Blog writer James Vasanth has written to share his insights with readers on the daunting DIY task of building a solar concentrator for solar hot water. He writes, “In this post, I’ll discuss some key points including how to build your own 2-axis parabolic concentrator.” Thanks, James. The “how-to” steps are welcome, however, a ready made version sounds even better after counting all the steps.
