Residential Energy Storage
A ‘Certificate of Sustainability’ has been awarded to the Megellan Residential Energy Storage System (RES1), meaning it has been approved for use by Western Power (Western Australia utility). The RES1 is a system that has been designed to store solar power produced during daylight hours for use at night. The system involves a 5kVA […]
Factors influencing the performance of solar thermal systems
It is important to understand the factors that influence the performance of solar thermal systems as they can be an ideal way to provide extra hot water to supplement energy delivered by heat pumps or boilers. A solar system can therefore be designed to deliver hot water reliably and meet the requirements of the household. […]
Green Energy Consultants
Green energy also referred to as renewable or sustainable energy are energy provisions that have no long term impact on the environment and are replenished by nature. They meet the energy requirements of the present without compromising the ability of future generations to meet their needs. Unlike the use of fossil fuels which cannot be […]
Record PV installation in 2009 and huge PV and concentrating solar power capacity for the future
According to Worldwatch Institute, in 2009 7.3 MW of new solar PV capacity was installed, a 20% increase form 2008 resulting in global PV capacity passing the 21 GW mark. In 2009 around 127 MW of concentrating solar thermal electric power plants came online. Europe has contributed the most significantly to PV demand, installing 72% […]
What is Passive Solar Design (PSD)?
PSD basically optimises a building’s form, fabric, and orientation to maximise solar gain from autumn to spring, whilst minimising it during the warmer part of the summer. At the same time, daylighting is maximised at all times.
What is Solar energy?
Solar energy is the energy of sun light. The temperature of the Sun’s surface reaches to a value of approximately 5,762 K. The Earth’s perimeter of 40,000km results in an intersected sun power of 174,000 TW. Attenuation by the atmosphere results in a peak intensity at sea level of around 1 kW/m2, giving a 24 […]
