List of rooftop photovoltaic installations

This page lists large-scale rooftop photovoltaic installation projects. Photovoltaic arrays in buildings are often either integrated into them, or mounted on to their roofs. Arrays are most often retrofitted into existing buildings, usually mounted on top of the existing roof structure. In 2010, more than four-fifths of the 9,000 MW of solar PV operating in Germany was installed on rooftops.^[1]

In 2011, the most common and newsworthy size for a photovoltaic power station is 1 MW.^[2] However, most of the large-scale stations are not installed on the roofs, but rather integrated with agriculture and some use innovative tracking systems that follow the sun's daily path across the sky to generate more electricity than conventional fixed-mounted systems. Many of all rooftop applications are done in small and medium-sized installations for consumption within the buildings that host the arrays. There are many large-scale installation projects which have been completed in the last decade and many are under construction or proposed.

The following lists the rooftop photovoltaic installation projects that are larger than 1 MW in total installation size. It does not include rooftop installations of non-building structures such as detached carports and tunnels.

Rooftop photovoltaic power stations

Many photovoltaic power stations are installed at the ground level. There are some large rooftop installations for the sole purpose of being power stations by connecting the systems directly to the grid to deliver electricity to customers. Many of these stations are installed on properties of non-utility companies such as warehouses through roof-area lease agreements and power purchase agreements between utility companies and property owners.^[3]

Net-metering rooftop installations

The followings are the large-scale rooftop installation projects with the main purpose of using the generated electricity as the supplemental power. When the systems generate electricity more than the host buildings can consume, the excess electricity is fed back to the grid to bank with the utility company through net metering. Below are large-scale multi-site installation projects with total size of rooftop units of 1 MW or larger.

Single-site installations

Each installation may be done on a single roof structure or on multiple buildings within the same site or campus.

Multi-site installations

Some property owners who have many smaller buildings located in multiple sites within the same area may take advantage of installing many medium-size systems in one project to achieve the large-scale power generation to offset their total power usage. The sites of the same owner are normally connected into the same monitoring system for easy maintenance of the overall system.
