Sunrun is a provider of photovoltaic systems and battery energy storage products, primarily for residential customers as per the official description about the company.
Solar business is a growing area and the company's financials are also improving in line with this growth trend.
The current market cap is around 5-6 billion USD and I think there will be more upside based on the positive market prospects and I am thinking a c.10x to a market cap of minimum 50 billion USD in the next years.
So, I am investing in this one for the long run.
Please comment if you have more insight about the company.
