Why choose solar?

According to SolarPower Europe, solar-powered renewables are the fastest-growing renewable technology, with the global solar capacity now exceeding one Terawatt, and the global solar market doesn’t show any signs of slowing down in growth. 

The fast-growing solar market means decreased costs of installation and overall expenses. The IEA reports that solar PV is becoming the lowest-cost option for new electricity generation in most of the world, which is expected to propel investment in the coming years.
