This company has had a revenue growth (TTM) of 97.5%.
They make micro-inverters which convert DC power to a balanced AC supply and are usually applied on solar panels. Micro-inverters are more efficient than their single string inverter counter parts and also offer more data and control over the system.
If you have solar panels in parallel feeding into a single string inverter, your power is limited to the weakest panel for example if a cloud were to cover 1 panel, it would reduce performance of the entire string.
ENPH has over 300 patents and their customer base includes both commercial and residential worldwide.
The company was founded in 2006 and in 2011 the company reached a milestone of 1 million micro-inverters shipped. As of today they have shipped more than 25 million micro-inverters.
The company also sell batteries and energy storage solutions and develops software associated with energy management.
In my opinion, ENPH is a promising company to have in your portfolio for long term. Renewable energy is growing rapidly around the world and this company provides solutions to some of the challenges associated with this change. Additionally, in less developed countries it is usually more economical to install solar than to build a fossil fuel plant, high voltage substations and transmission lines which would all be needed. As these less developed countries begin to develop, the demand for this technology is going to grow even faster.
