Tesla misses own expectations for Solar Roof deployments

Three years ago, Tesla said it expected to install 1,000 solar rooftop arrays per week, which would have amounted to 156,000 Solar Roofs in that time period. However, Wood Mackenzie reports that just 3,000 have been installed to date.

Canada formalizes 30% federal ITC credit, other incentives

Canada’s new policy plan mirrors the US Inflation Reduction Act (IRA), including two new input tax credits (ITCs) targeting clean energy and technology manufacturing that will remain at 30% through 2033, stepping down to 15% in 2034 before phasing out altogether after 2034.


New software modeling tool for agrivoltaics

Sandbox Solar, a solar developer and US federal grant recipient, has released a beta version of its software modeling tool for agrivoltaic power plants. It supports the design and optimization of solar panels, as well as the crops underneath.

Developer starts building 800 MW project with US components in Illinois

Swift Current Energy is set to begin construction on an 800 MW project by the fall of 2024.

Weekend Read: Shingle all the way

While shingled cells have been around for a while, Tongwei’s adoption of the technology is notable as it is a manufacturer with considerable scale. If shingling can overcome some hurdles, it could prove a welcome solution as unshaded sites for PV become elusive in mature solar markets.


Temperature estimates for floating PV modules

Scientists from the United States and Brazil have developed four different ways to estimate the temperature of floating PV modules. They validated the models with temperature measurements from a floating solar plant in Brazil.


FERC says 1,700 GW of US renewables still awaiting interconnection

The US Federal Energy Regulatory Commission (FERC) says that just 86 GW of power projects based on fossil fuels are awaiting interconnection, while 1,700 GW of solar, wind, storage remain delayed.
