Over the years, we've easily converted to passive solar
heating, solar hot water, and electrical generation through solar panels, as those technologies became viable.
It is an important source of renewable energy and its technologies are broadly characterized as either passive solar
or active solar depending on how they capture and distribute solar energy or convert it into solar power.
The 2018 theme was "Engineering a Greener World," and the main challenge revolved around passive solar
Based on the various product segments the market can be categorise in two broad categories namely active solar water heater and passive solar
It addresses the energy problem; what is needed for human comfort; heat losses from a structure; materials used in residential construction and construction techniques; the seasons and solar angles; the transmission of light through the atmosphere; solar gain and attenuation; the transmission of solar energy through glazing; climate and the siting of a solar structure; the history of solar structures; passive solar
collection; non-concentrating, active solar collectors; photovoltaic panels; smart grids, FiTs (feed in tariffs), and net metering; architectural considerations for capturing solar energy; and methods of energy storage.

The valuation of Energy Star homes, passive solar
houses, solar photovoltaic systems, and net-zero energy homes is also explored.
Along with the new discoveries there is great focus on the passive solar
energy gain, passive solar
building design is used in which windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer.
heating techniques for houses--a combination of strategically-oriented glazing, fixed solar shading, thermally massive interior building components, and a well-insulated and airtight enclosure--are among the most cost-effective and technically simple approaches towards achieving low and net-zero energy design in cold and temperate climates (Balcomb 1992).
Another example is in South Africa where developers have designed and built passive solar
low-cost housing communities that provide year-round comfort without mechanical heating or cooling systems.
The clinic was built with extreme energy efficiency in mind, utilizing air-to-air geothermal heat exchange which minimizes heating fuel costs and incorporates passive solar
features and skylights for natural lighting.
