2. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   Solar air heating is a renewable energy heating technology used to heat or condition air for buildings or process heat applications. It is typically the most cost-effective of all the solar technologies, especially in large scale applications, and it addresses the largest usage of building energy in heating climates, which is space heating and ...

3. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   Below is a table that gives a rough indication of the specifications and energy that could be expected from a solar water heating system involving some 2 m 2 of absorber area of the collector, demonstrating two evacuated tube and three flat plate solar water heating systems. Certification information or figures calculated from those data are used.

4. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   Solar heat (or heat from other sources) can be effectively stored between opposing seasons in aquifers, underground geological strata, large specially constructed pits, and large tanks that are insulated and covered with earth. Short-term storage. Thermal mass materials store solar energy during the day and release this energy during cooler ...

5. Solar pond - Wikipedia

   en.wikipedia.org/wiki/Solar_pond

   Diagram of a solar pond. A solar pond is a pool of saltwater which collects and stores solar thermal energy. The saltwater naturally forms a vertical salinity gradient also known as a "halocline", in which low-salinity water floats on top of high-salinity water. The layers of salt solutions increase in concentration (and therefore density) with ...

6. Solar panel - Wikipedia

   en.wikipedia.org/wiki/Solar_panel

   A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. These electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
