2. Photovoltaic mounting system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_mounting_system

   As the relative costs of solar photovoltaic (PV) modules has dropped, [3] the costs of the racks have become more important and for small PV systems can be the most expensive material cost. [4] This has caused an interest in small users deploying a DIY approach. [5] Due to these trends, there has been an explosion of new racking trends.

3. Photovoltaic system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_system

   A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

4. Rooftop solar power - Wikipedia

   en.wikipedia.org/wiki/Rooftop_solar_power

   Rooftop mounted systems are small compared to utility-scale solar ground-mounted photovoltaic power stations with capacities in the megawatt range, hence being a form of distributed generation. A comprehensive life cycle analysis study [ 3 ] showed that rooftop solar is better for the environment than utility-scale solar. [ 4 ]

5. Passive solar building design - Wikipedia

   en.wikipedia.org/wiki/Passive_solar_building_design

   In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.
