Designing Passive Solar Energy(The following design strategies are with respect to the Northern Hemisphere) 1- Location with respect to the sun: Optimum sun absorption is crucial for solar energy
Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy. In its core, the sun fuses about 620 million metric tons of
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. [2] Concentrated solar power systems use lenses or mirrors and solar
We install solar exclusively during construction, so we understand what''s most important to builders on site. 8 of the top 20 homebuilders in Australia choose Energybuild for their solar installs. "By installing during
Energy can be harnessed directly from the sun, even in cloudy weather. Solar energy is used worldwide and is increasingly popular for generating electricity, and heating or desalinating water. Solar power is generated in two main ways: Solar photovoltaic (PV) uses electronic devices, also called solar cells, to convert sunlight directly into electricity.
Zero energy buildings are designed and built to consume as little energy as possible. When a renewable source of energy is added to these buildings, they are capable of producing enough energy to meet or exceed their requirements to run. More About Zero Energy Buildings. More About Zero Energy Buildings on the Residential Side – Zero
In Hong Kong, buildings account for over 90% of electricity usage, creating over 60% of the city''s carbon emissions. One of the critical measures to achieve the carbon neutrality target is to reduce coal-fired and natural gas-fired electricity generation, while increasing the proportion of electricity production from renewable energy. As a pioneer in

The Solar Futures Study finds that solar energy could power about 14% of transportation end uses by 2050. Solar PV couples well to electric vehicle (EV) charging: Both use direct-current electricity, which avoids efficiency losses in conversion to alternating-current electricity—a much as 26% lost, in some cases.
Solar energy can integrate with energy-use equipment, such as heat pumps and absorption chillers, to provide heating or cooling for buildings. A few studies and projects have been reported recently regarding the use of DC power generated by solar PV systems to directly drive variable-frequency heat pumps.
