Tesla, which lost its status as the nation’s leading rooftop solar company last year, says it has figured out how to get back in the game — by slashing prices.

The company plans to announce on Tuesday that it has started selling solar panels and related equipment for up to 16 percent less than the national average price by standardizing systems and requiring customers to order them online. Tesla executives said these changes should put to rest concerns that the company, better known for its luxury electric cars, has neglected its residential solar business.

But it is not clear whether the strategy will work or is even feasible. Tesla and its chief executive, Elon Musk, have struggled to deliver products on time that they announced with great fanfare, including a $35,000 version of its Model 3 electric sedan. The company has also struggled with quality problems.

Last week, Tesla reported a $702 million loss in the first quarter as deliveries of cars and solar systems tumbled. The company’s stock price is down by more than 27 percent so far this year, and many analysts believe it will soon need to raise money by selling shares or bonds because its cash holdings dropped by about $1.5 billion in the first three months of the year.
