Long read: Shadow boxing

The amount of non-uniform shading an array will experience determines the technology choices that can be made. However, it can be complicated to formulate more general rules for when to use what type of technology. Most would agree that module-level power electronics are better at handling non-uniform shading, but how do they handle the sun? A recently promoted study brought the discussion into sharp relief.

A closer look at hydrogen infrastructure

Momentum is building for a new era of the hydrogen economy. Green hydrogen production is decreasing in cost, as greater levels of renewables are being integrated into the grid, and countries are developing hydrogen plans. Shayne Willette from Navigant sets out how, as a result, hydrogen is increasingly recognized as a potentially significant contributor to the decarbonization of the energy sector.

Record shipments push global solar PV inverter market past $9 billion in 2019

The PV inverter market achieved record shipments in 2019, writes IHS Markit’s Miguel de Jesus, driven by booming shipments in key markets such as the United States, Spain, Latin America, Ukraine and Vietnam. Revenue rose rapidly, surpassing the $9 billion mark in 2019 for the first time.

What’s going on in the world of thermal energy storage?

Can this technology be commercialized? A partnership between Siemens Energy and EnergyNest to develop thermal storage solutions together is the latest development in an industry with lots of potential, but little practical application thus far.

Business & Human Rights Resource Centre investigates human rights issues in solar, wind

An assessment of the human rights performance of the world’s leading solar and wind power companies has painted a grim state of affairs, with the only dedicated solar manufacturer analyzed scoring 7%.

PV module prices are falling faster than all predictions

New research from Wood Mackenzie shows that overall system costs for installations using mono PERC modules are set to fall by as much as 20% by 2025.

Premature inverter failure – 4.2 GW of capacity will be affected this year, says analyst

U.S.-owned business intelligence firm Wood Mackenzie has attempted to evaluate the market opportunities offered by the repowering of solar projects around the world which feature inverters which are 10 years old – as well as those which will expire ahead of time.

Blockchain P2P solar energy trading proves feasible and popular in world-first trial

An Australian government-backed trial of peer-to-peer (P2P) solar trading has demonstrated the potential of localized two-sided energy markets and blockchain technology to improve the energy system. However, current electricity tariff structures would need to be modified to realize the full stack of values that this technology has to offer.
