Home batteries: What are they, and is it worth it for you to get one?

Rooftop solar panels are common in Arizona thanks to abundant sunshine, but to get even more use from the technology, homeowners are beginning to pair them with large home batteries.

Batteries allow homeowners to store their surplus electricity, rather than send it to the grid in exchange for credit from their electric company.

Should you install solar on your home? 10 key considerations

Arizona's endless sunshine continues to make rooftop solar panels an enticing proposal for homeowners. Already, tens of thousands of Arizonans have installed panels to make electricity for them, and falling prices and new financing options continue to draw consumer interest.

But homeowners should consider several questions before deciding to install rooftop panels. Here are 10 primary considerations you should think about before signing a contract:

White House seeks 72 percent cut to clean energy research

The Trump administration is poised to ask Congress for deep budget cuts to the Energy Department’s renewable energy and energy efficiency programs, slashing them by 72 percent overall in fiscal 2019, according to draft budget documents obtained by The Washington Post.

Many of the sharp cuts would probably be restored by Congress, but President Trump’s budget, due out in February, will mark a starting point for negotiations and offer a statement of intent and policy priorities.

Mandalay to build 3,000 Arizona homes with solar and Sonnen batteries

(Reuters) - German battery maker Sonnen GmbH on Thursday said it would partner with home builder Mandalay Homes to outfit 3,000 new Arizona homes with batteries to store the excess energy generated by their rooftop solar installations.

Mandalay plans to build the homes in Prescott, Arizona with the batteries, which can cost between $10,000 and $20,000. The cost would be part of the home’s sale price and wrapped into the mortgage.

The companies want utilities to pay the homeowners to use the stored power in the 3,000 batteries, which would create a virtual power plant with 8 megawatt hours of electricity, enough to power about 5,000 average homes for a day.

For now however, the project is moving forward without buy-in from utilities. Sonnen’s U.S. arm and Mandalay have been in talks with Pinnacle West Capital Corp’s Arizona Public Service and Salt River Project for a few months, they said.

The community would be the first of its kind in the United States, the companies said, and comes as utilities have been studying the potential benefits of integrating battery storage along distribution grids and decreasing reliance on centralized fossil fuel plants. Sonnen has several such communities in Germany, but the idea is still a novelty in the United States.

Batteries are viewed as especially key in large solar energy markets like Arizona that generate more power than they need during the sunniest times of the day.

Sonnen has about 1,000 home batteries deployed in the United States currently, and aims to get to at least 20,000 by 2020, in part through more deals with homebuilders.

Arizona Public Service would not comment on talks with Sonnen and Mandalay, but said batteries “can provide benefit to both our customers and the grid.”

Salt River Project spokeswoman Kathleen Mascarenas said “no agreements are in the works.”
