ZenithSolar technology

By using curved mirrors that can collect five times more energy than ordinary solar collectors, new technology developed by Israeli company ZenithSolar is making solar power cost competitive against fossil fuels for the first time. The incredible technological advance can improve overall solar power conversion efficiency up to 75 percent. In fact, if Zenith's curved solar panels were placed on just 12 square kilometers of land, 10 percent of Israel’s population could live on the energy.
