2. Metal roof - Wikipedia

   en.wikipedia.org/wiki/Metal_roof

   Metal roofs emissivity is better at reflecting solar radiation at 10%–75% depending on the color choice, compared to asphalt roofs that reflect 5%–25% depending on their color. Over the lifetime of the metal roof they keep 95% of the reflective capacity compared to other roof types that lose 20%–40% of their reflective capacity.

   en.wikipedia.org/wiki/Reflective_surfaces...

   While cool roofs are mostly associated with white roofs, they come in a variety of colors and materials and are available for both commercial and residential buildings. [2] Painting roof materials in white or pale colors to reflect solar radiation is encouraged by legislation in some areas (notably California).

5. Metal profiles - Wikipedia

   en.wikipedia.org/wiki/Metal_profiles

   Metal profile sheet systems are used to build cost efficient and reliable envelopes of mostly commercial buildings. They have evolved from the single skin metal cladding often associated with agricultural buildings to multi-layer systems for industrial and leisure application. As with most construction components, the ability of the cladding to ...

6. Rooftop solar power - Wikipedia

   en.wikipedia.org/wiki/Rooftop_solar_power

   Though designs may vary with roof type (e.g. metal vs shingle), roof angle, and shading concerns, most arrays consist of some variation of the following components Solar panels produce carbon free electricity when irradiated with sunlight. Often made of silicon, solar panels are made of smaller solar cells which typically have six cells per panel.
