Following eight months of construction, India has finished building its new solar power farm in Kamuthi which will replace California’s Topaz Farm as the world’s biggest solar plant. The massive facility packs 648 megawatts, which should suffice to power over 150,000 homes, and consists of 2.5 million solar modules, 576 inverters, 154 transformers as well as 6,000 kilometers of cables.

The solar plant spreads over 2,500 acres (or 10 square kilometers) of land and costed a total of $679 million to build. By comparison, Topaz Farm, which can generate up to 550 megawatts of power, took almost two years and over $2.5 billion in funds to build.
