Painting roofs white helps lower city heat, studies say
White or reflective paint is more effective at cooling cities than covering roofs in solar panels or greenery, scientists say, and could offer some relief on extremely hot summer days.

A photovoltaic module or photovoltaic panel is a packaged interconnected assembly of photovoltaic cells, also known as solar cells. The photovoltaic module, known more commonly as the solar panel, is then used as a component in a larger photovoltaic system to offer electricity for commercial and residential applications.
Because a single photovoltaic module can only produce a certain amount of wattage, installations intended to produce larger electrical power capacity require an installation of several modules or panels and this is known as a photovoltaic array. A photovoltaic installation typically includes an array of photovoltaic modules or panels, an inverter, batteries and interconnection wiring.
Photovoltaic systems are used for either on- or off-grid applications, and for solar panels on spacecraft.
