Proposed photovoltaic module form factor to reduce levelized cost of energy

This paper discusses a proposed photovoltaic (PV) module form factor designed for utility-scale, one-axis tracking projects. The purpose of the form factor is to: 1) reduce total installed costs for utility-scale projects; 2) improve module reliability; 3) reduce operating and maintenance (O&M) costs, and 4) improve the project return on investment. The proposed module uses a double-glass construction to improve reliability and service lifetime in a form factor that is longer and narrower than existing 60-cell modules. This form factor places more module area per linear meter of torque tube when used with single-axis trackers. These changes are expected to lower the levelized cost of energy.
