Tailored for landowners like farmers and building owners, our analysis delves into the essentials of land and roof lease agreements. It covers key aspects such as lease rates, tax responsibilities, and end-of-life terms for solar installations.

Solar System Ownership

We provide in-depth insights into the logistics and economics of owning a solar power system, covering costs, return on investment, incentives, permits, zoning, and feasibility studies.

Initial System Design

A high-level solar power system layout and an electrical single-line diagram optimized for system size and production. We also offer a breakdown of system components such as solar panels, inverters, and racking, as well as the types of labor required.

Our CPA, whose focus is on commercial real estate and solar power, offers valuable insights on tax benefits, helping you make the most of your solar investment.


We will analyze your site, building, or ideas for legislative, technical, and financial feasibility. If the project isn’t possible, we’ll let you know quantitatively.

Preliminary Interconnection and Zoning Analysis

Various pre-development tasks and resources need to be undertaken to determine if a solar site is feasible for solar development, including feasibility studies, red flag land analysis, hosting capacity studies, and other preliminary actions that determine if a project is viable.

Electrical and System Design Engineering

Working alongside Benjie is Mark Eckert, a Licensed Professional Engineer with a multifaceted engineering background, including electrical system design expertise and a Renewable Energy degree from Penn State University.
