Experience, Capacity & Qualifications :: About Us
Our Experience and Capacity
Founder and owner Geoff Greenfield has been designing and installing renewable energy systems since 1997. After working in the field independently and as a subcontractor, Geoff formed the Limited Liability Company (LLC) Third Sun Solar & Wind Power Ltd. in 2000. Today we have the management and technical capacity to direct multiple concurrent projects with a high level of confidence, service and performance.
Our experienced management team and modern information technology systems allow us to meet and exceed our customers' needs on a regular basis. You can count on a Third Sun project to run smoothly as we combine our financial and management experience, our multiple installation crews, our network of subcontractors and professional services partners, with our established internal systems to deliver results that consistently exceed expectations.
We are proud of our internal "back office" capacity that includes full time engineers, financial and clerical personnel all focused on customer value and responsiveness. This experience and capacity serve our customers in many ways, whether in the form of accurate and timely submittals, full compliance prevailing wage reporting, risk management, safety programs and compliance documentation or just answering the phone with a human voice rather than a machine.
Over the years we have developed ongoing partnerships with a variety of customers. We have found that each customer sector we serve has different needs and expectations regarding a renewable energy firm. Responding to this we have grown based on a commitment to understanding, identifying and then exceeding each customer's specific requirements.
Our extensive client list includes:
- Corporations and Privately held companies
- Real Estate Developers and Builders
- Construction Companies (General Contractors and Subcontractors),
- ESCOs (Energy Service Contractors or Performance Contractors),
- Regulated, Municipal and Co-Operative Utility companies,
- Units of Local, State and Federal Government,
- Institutional and Non-Profit customers,
- Public and Private Universities,
- Public and Private School districts,
- Residential end-users.
We pride ourselves on our professional and responsive service and performance. This is a direct result of our well-trained, experienced and dedicated staff. Every employee of Third Sun, from office staff to field installation crews, is fully trained and qualified for their job, often holding specialized degrees as well as industry and manufacturer specific training certificates. To stay at the forefront in value delivery in the dynamic world of renewable energy, our culture includes a commitment to continuous improvement and ongoing continuing education.
