Anticipating silicon solar cells with significantly improved efficiency

Theoretical calculations indicate that under certain conditions silicon can endow solar cells with a much higher efficiency. Small silicon clusters may provide a source...

Ground based PV soiling control

A recent article highlighted the steps taken to gain a few percentage points in the efficiency of PV panels. While these small gains can...

The digitalisation of PV operations

All eyes are on digital technology as European PV plant operators continue to seek meaningful reductions in asset management and operations and maintenance (O&M)...

Lightning and surge protection for rooftop PV systems

Rooftop photovoltaic (PV) systems are extremely exposed and therefore especially vulnerable to damage caused by the direct and indirect results of lightning strikes. Since...

Case study: Largest wind farm in Africa

The Lake Turkana Wind Power (LTWP) project, located in Marsabit County, Kenya, is the country’s single largest private sector investment at €685-million; and the...

Measuring the performance of large building integrated PV (BIPV) systems

Building-integrated photovoltaic systems (BIPV), more commonly known as rooftop solar, has become common in many distribution networks. While most systems are small and do...

Water powers one of Africa’s largest gold mines

Located in the remote north-east province of Democratic Republic of Congo (DRC), the 11 MW Azambi Hydropower Project was developed to support the increasing...

Artificial intelligence improves forecasting for renewable energy systems

As the penetration of renewable energy (RE) increases, accurate forecasting of both production and demand become more important. Forecasting allows balancing of RE and...

Managing and operating solar assets: Five key considerations

PV was supposed to be like any other energy source: You invest in the infrastructure and then it pretty much runs itself from thereon....

Little-known tax incentives boost business case for renewable energy

South Africa’s government, energy regulator and Eskom have often been criticised for obstructing the introduction of distributed, small-scale embedded generation (SSEG) which would help...
