Thanks for searching for an experienced solar installer. I have been making a living in solar (electric and thermal) since before 2000. Additionally, my engineering training (Missouri Professional Engineer, awarded in 1978), and Saint Louis County Master License testify that you are getting a very well qualified technician for your projects. I personally use the products and technologies I sell. I doubt that I will be the lowest cost provider, but the design and installation of your system will be second to none, be that solar electric, solar hot water, solar hot air, solar pool heating, or advanced appliances like tankless water heaters. Moreover, as exemplified by my proven commitment to this technology, I will be around to service and expand your equipment long after the recent addition of solar (tax credit) experts has gone on to even more lucrative pickings.
