What happens to the electricity in your home during a power outage when you have rooftop solar panels installed?

A top priority for EERE is supporting game-changing manufacturing innovations across multiple sectors, including American solar panel manufacturing.

An innovative system being developed at DOE's Argonne National Laboratory can quickly store heat and release it for use when needed.

One of the ways the Energy Department is driving innovation in the solar technologies is through prizes such as the American-Made Challenges.

Part 2 of the PV Cells 101 primer, exploring new materials and cell designs that can improve conversion and performance.

Part 1 of the PV Cells 101 primer explains how a solar cell turns sunlight into electricity and why silicon is the semiconductor that usually does it.

Universities and community colleges can join the inaugural DOE Solar District Cup, to re-imagine how solar energy is generated, managed, and used.

This blog post will explain the terminology around solar-plus-storage, how many solar-plus-storage systems are in the country, and what they cost.

The solar industry is on the move—expanding into new states and creating new business opportunities across the country.

New NREL research will help ERCOT better manage its solar power and integrate it with the 20 gigawatts of wind capacity already installed in the state

Solar energy provides as much as 15% of generation on the grid in some states, solar energy can provide grid services to maintain system balance.

Power electronics are essential to the safe and efficient operation of solar PV systems, serving as a critical gateway between solar and the grid.

In this new blog series, we ask Energy Department researchers about their life as scientists working with energy efficiency and renewable energy.

Developments in concentrating solar thermal power could improve grid flexibility by unlocking new choices to better meet grid operator needs.

Energy Department research is taming the duck curve by helping utilities better balance energy supply and demand on the grid.

For the first time ever, ganged heliostats could be a viable option for new concentrating solar power systems.

Should I make the leap to solar energy? Is my home suitable for solar? Does it make financial sense to go solar? Who should I go to for installation?

While only lasting about two minutes in each location, the eclipse will dramatically decrease output of photovoltaic power plants across the U.S.

As costs drop and energy production rises, solar technologies will be put to more work. Here are 4 unusual uses for solar power today.

Capacity is the maximum output of electricity that a generator can produce. Generation is the amount of electricity that is produced over a set time.

Four fast facts that every solar prosumer should know.

The Energy Department is working toward maximizing the use of solar energy to produce electricity—even when the sun isn’t shining.
