The launch of Sunrun's new add-on storage offering is directly related to the company's business operations and could potentially impact its financial performance. The increasing demand for energy storage in California, coupled with the fact that more than 85% of Sunrun's new sales in the state included a battery in the most recent quarter, suggests that the offering could be well-received by customers and lead to increased sales and revenue for the company. Furthermore, the offering could enhance Sunrun's reputation as a leading provider of clean energy solutions, which could potentially attract more customers and further boost the company's financial performance.
