New innovation in Heat Pump design for high temperature applications.

French startup unveils new residential thermo-acoustic heat pump Equium has developed a new thermo-acoustic heat pump core that reportedly produces 3 kW to 4 kW of heat for every kilowatt of power it consumes. It says the refrigerant-free device could generate domestic hot water at temperatures of up to 80 C.

The new Ecogenica commercial Heat Pump Water Heater - designed by Sustainable Energy Systems - promises to radically change the way businesses make hot water - to save energy costs.

Cleaning Solar Panels. Should you?

Panel upkeep is a necessity as dust build-up poorly affects your panel’s performance. How often your solar panels should be cleaned is influenced by many factors.

Does dust affect solar panels? The short answer is yes!

The greatest factors that contribute to dust build-up are your geographical location and the surrounding elements that might pollute your system.

While heavy rain, as some smaller studies suggest, might help to clean and clear debris and pollutants from your panels, most large studies report that dust build-up can lower the efficiency of our system in just a minute – around 5% or less.

One study found that solar panels that are properly maintained perform 3.5% more efficiently. CleanTechnica reported an analysis, gathered by the US National Renewable Energy Laboratory (NREL), that panels lose around 30% if not cleaned properly.

A recent study found that ‘due to the accumulation of dust the efficiency of solar modules and panels in terms of power can be reduced up to 60%’. Additionally, ‘The research inferred that the mean of the daily energy loss along a year caused by dust deposited on PV module surface is around 4.4%’

While dust is a common pollutant, leaves also block sunlight, thus affecting your panels’ efficiency. Mountain View, a solar energy provider, reports that clean panels can double the energy overnight, even after 15 months of operation.

Solar systems installed in dust-prone areas, such as near main roads and farmlands, will require more frequent and thorough maintenance. Failure to clean dust off panels installed in such areas can see a detrimental impact on solar production. Research has noted that the ‘reduction in solar efficiency due to dust on PV panel is approximately 40%’ in dust-prone areas.

More than 25% of Australian households now have rooftop solar installed.

Rooftop solar shines as renewable energy share jumps to 35% Australia has set renewable energy records for the fifth consecutive year with new data showing clean energy accounted for nearly one-third of the electricity produced in the National Electricity Market in 2021, with the continuing roll out of rooftop solar PV spearheading the switch away from tradi...

Great results from LG solar panels - I’m sad to see them exist the market.
