Livguard unveils wall-mountable inverters for residential solar
Indian manufacturer Livguard Solar has developed single-phase, grid-interactive inverters with rated power outputs of 3 kW and 5 kW, and efficiencies of 97.7% and 98%, respectively.
Pakistani regulator to raise payments for net-metered households
Pakistan’s National Electric Power Regulatory Authority (Nepra) has concluded a public consultation on a proposed amendment to 2015 regulations for distributed generation and net metering. It will raise the price paid by net-metered households to inject excess electricity into the grid from PKR 19.32 ($0.089)/kWh to PKR 9/kWh.
Vertical PV to protect biodiversity at German airport
An 8.4 kW pilot vertical PV project is now operating at the airport in Frankfurt, Germany. The solar panels are vertically arranged to protect the biodiversity of the site. In the final stage of expansion, the system will reach up to 13 MW of output.
Australian company targets solar panel industry with high-grade silica
Allup Silica aims to target the booming solar PV panel industry after independent tests confirmed the presence of premium silica sands – a key component of high-end glass manufacturing – at its Sparkler project in Western Australia.
New refrigerant circuit for safer, more efficient heat pumps
Scientists at Germany’s Fraunhofer Institute ISE and a consortium of heat pump manufacturers have achieved a new efficiency record in their development of a low-refrigerant propane refrigeration circuit. The device has a heating capacity of 12.8 kW with only 124 grams of propane, amounting to a refrigerant charge of approximately 10g/kW, compared to 60g/kW for commercially available devices.
EU solar ‘big buyers’ initiative set to launch in November
The European Commission intends to help municipalities and public entities to buy rooftop PV systems. Its DG Growth initiative aims to make the public procurement of rooftop solar systems easier.
Reflective coating to reduce solar tile temperatures
Australian scientists have tested different reflective coatings in solar tiles and have found that they could improve the performance of building-integrated PV devices by up to 6.6%. They are currently working with building product manufacturers to bring their tech closer to commercial production.
DC rooftop PV providing domestic hot water to residential building at 60 C
Domestic hot water, with a heating system powered exclusively by DC solar power, has now covered the needs of an apartment building in Linz, Austria, for a period of a year. The 14 residential units are each connected to their own 1.36 KW solar arrays.
