2. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Twin-wall plastic, specifically twin-wall polycarbonate, is an extruded multi-wall polymer product created for applications where its strength, thermally insulative properties, and moderate cost are ideal. [1] Polycarbonate, which is most commonly formed through the reaction of Bisphenol A and Carbonyl Chloride, is an extremely versatile material.

3. Passive solar building design - Wikipedia

   en.wikipedia.org/wiki/Passive_solar_building_design

   Wall thicknesses should be similar to a thermal storage wall. If a water wall is used between the sunspace and living space, about 0.20 ft 2 of thermal mass wall surface per ft 2 of floor area being heated (0.2 m 2 per m 2 of floor area) is appropriate. In most climates, a ventilation system is required in summer months to prevent overheating.

4. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate. Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many ...

5. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   Space heating for residential and commercial applications can be done through the use of solar air heating panels. This configuration operates by drawing air from the building envelope or from the outdoor environment and passing it through the collector where the air warms via conduction from the absorber and is then supplied to the living or ...

6. Photovoltaics - Wikipedia

   en.wikipedia.org/wiki/Photovoltaics

   Solar panels on the International Space Station. Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors.

7. Solar thermal energy - Wikipedia
