Improvements in solar array technology and competitive cost pressures in solar energy products are enabling rapid industry growth. As a result, solar systems are becoming increasingly cost-effective for residential and commercial use, especially when global government incentives for implementing green technologies are taken into account. AMETEK has extensive knowledge of the requirements and solutions for solar power systems. Today, the large majority of world solar product sales are in applications tied to the electricity grid. This white paper will focus on the testing requirements of these grid-tied solar products.
