This article discusses the often-overlooked technical considerations involved in designing and laying out a high-performance solar system.

While subsidies have provided an important early boost, the future of residential solar affordability rests on financing models that expand access consistently. Loans create a pathway for households across diverse income brackets and geographies to invest in clean energy without waiting for government support.

Sandia National Labs researchers have created a new dataset on the rates and types of rooftop PV connector failures.
