Solar power by country in China. The Sarnia plant covers and contains about 966,000 square metres (96.6 ha), which is about 1.3 million thin film panels. The expected annual energy yield is about 120,000 MW·h, which if produced in a coal-fired plant would require emission of 39,000 tonnes of CO per year. Canada has many regions that are sparsely populated and difficult to access, but also does not have optimal access to sunlight given the high latitudes of much of the country. Photovoltaic cells are increasingly used as standalone units, mostly as off-grid distributed electricity generation to power remote homes, telecommunications equipment, oil and
