Shares of residential solar company Sunrun (RUN - Get Report) rose as much as 6% Friday as blackouts in California inspire more consumers to seek backup power solutions.

Sunrun stock at last check was up 4.7% to $17.74.

Utility giant PG&E (PCG - Get Report) cut power to parts of 22 counties this week in an attempt to avoid sparking a wildfire. 

"Once again ratepayers are focused on concerns regarding resilience in the case of blackouts, and what alternatives are available," JMP analyst Joseph Osha said in an Oct. 11 note.

He reiterated his market outperform rating and $26 price target on Sunrun, describing the company as the largest residential solar development business in the industry.

"RUN is ideally positioned to benefit from the state's latest round of disillusionment with its largest utility," Osha wrote.

"We expect uptake of solar-plus-storage solutions in the residential retrofit market to continue accelerating as a result of this past week's events."

Credit Suisse analyst Michael Weinstein said in an Oct. 10 note that the California blackouts are positive for solar and storage backup demand, "which could materialize in lower-cost lead generation across the state for potential installations next year."

He said the demand would be positive for residential solar developers, while reiterating his outperform recommendation and $26 target on Sunrun.

Shares of Sunrun are up about 63% so far this year.
