Sustainability is at the forefront of the world's agenda. And, sustainable design is, more than ever, a key consideration for the building industry. As the greening movement has gained momentum, Solar Photovoltaic Systems have increased in popularity as an effective tool that architects and builders can specify to reduce a building's environmental impact.

The amount of energy produced by a solar energy system depends on a number of factors including solar insolation at the site, angle and orientation of modules, and shading.

The table below shows examples of 3 hypothetical 100m2 systems located in London, Tokyo, and Los Angeles. For these examples, assume that each installation has a south facing roof at a 30 degree angle with no shading.
