Solar photovoltaics is growing rapidly, albeit from a small base, to a total global capacity of 139 GW at the end of 2013. The total power output of the world’s PV capacity is equal to some 160 bil kWh of electricity a year. This is sufficient to cover the annual power supply needs of 40 mil households in the world, and represents 0.85% of worldwide electricity demand.
More than 100 countries use solar PV. China, followed by Japan and the United States is now the fastest growing market, while Germany remains the world's largest producer, contributing almost 6% to its national electricity demands.
Thanks to a generous state subsidy, the Czech Republic become an important customer of photovoltaic panel producers, In 2010, the country operated nearly 5% of world's worldwide installed photovoltaic power (or 1,953 MW). Following the subsidy cuts, however, the solar boom slowed down significantly and Czech Republic's global share dropped to "only" 1.55%.
