Do you think investing in solar energy companies at this time would be wise?

I came across "Envision Solar International Inc.(EVSI)" today. They are building solar trees in parking lots. The solar panels can track the movement of the sun to allow the panels to absorb more of the sun’s energy during the day. In addition to providing shade for electric vehicles, customers will also be able to charge their vehicles. One is already in use at the Dell Co. headquarters. It’s a penny stock currently selling at around {content}.47 per share. This is the first company to do this. I’m thinking about purchasing 10,000 shares for the "future".
