Want to build solar power on your commercial property?

Technology moves fast, and It takes experience to know a good investment. With more than a decade of work in solar finance, development and construction, I will help you save solar construction costs through education and project management.

What I’ll do for you:

  • Design the layout of a complete solar system, defining a bill of materials.
  • Provide a financial analysis, including electricity production, revenue stream projections, tax consequences, and operations and maintenance costs.
  • Deliver a complete cost breakdown of components, labor, and services. This includes: comparisons with national data and profit margins.
  • Handle the paperwork that drives federal incentives, the local power company, permits and state level requirements.
  • Act as your Project Developer and guide you through professional scrutiny – with electrical and structural engineers, CPAs and bankers, permitting and hiring contractors.


Everyone knows the environmental benefits of going green, but John taught us the financial benefits of a commercial solar installation. We’re combining solar power, batteries, and car chargers. It’s a complex project, with multiple moving parts. John said his advice was more peace of mind than anything else, and in the end he was right.

I feel like the decision we made – reaching out to John after reading about him online – was the right decision. We’re expecting to earn $250,000 in the first year, from our roof, because of solar power.

Going green CAN save green, but it’s a minefield that we need people like John to help us navigate. I can’t thank him enough for thinking this through with me.
