How does solar power work?

When the sun is shining, rooftop solar panels collect energy from the sun. Solar panels take the sun’s energy, and convert it into usable electricity using microinverters. The usable electricity flows from the panels, through the net meter, and into a home to power appliances. Learn more

Are Vivint Solar customers connected to the grid?

Yes. Vivint Solar uses “on-grid” systems, meaning that they are still connected to the electrical grid. On-grid solar energy systems are necessary to transfer excess power into the grid, which can result in a credit to customers in some states. On-grid systems also keep you connected to the grid for additional power from the utility.

What determines whether my home is a good candidate for solar?

We conduct an on-site survey to determine if your home is compatible for solar. Here are some examples of what we evaluate to make sure that solar is a good fit:

  • Roof size, pitch and direction
  • Shading of the roof caused by tree branches, other homes, etc.
  • Roof obstructions such as chimneys, pipes, etc.
  • Roof stability and strength
  • Electrical wiring
Will solar panels work in overcast climates?

Yes, but performance may be affected. Solar panels produce more energy when the sun is shining.

How long will it take to get the solar energy system turned on after installation?

Getting permission to operate a system and start generating energy largely depends on your local city and utility company. We will be able to give you a better idea of your operating timeline after your system installation.

What’s the difference between solar power and other forms of energy production?

Solar power is energy that comes from the sun, while many other forms of energy come from fossil fuels (coal, petroleum, and natural gas). Both can be used to power your home, but they are generated differently. Energy from fossil fuels goes through multiple steps before reaching your home, including step-up transformers, transmission substations, and distribution substations. Solar power is collected by panels on your roof, then immediately converted into usable energy.
