The Case for Microinverters in C&I Solar

AP Systems Microinverters Special Report

Technology is changing the norms of commercial and industrial (C&I) rooftop solar system design. Panels are getting huge and climbing upward of 600 W. UL 3741 compliant systems are expanding options for meeting NEC 690.12. And beefed up microinverters are poised to do for C&I what they’ve done for residential solar — simplify everything. Unsure about that last one? Then it’s time to get up to speed on the advancements of microinverters built for C&I. Solar Builder explores the case with APsystems in this special report. Download it here.

Breaking Down and Breaking Through Soft Costs

In the US residential solar market, system costs have declined by 25% since 2014. However, customer acquisition and overhead costs have increased by 31% during the same time. Additionally, the Solar Energy Industries Association points out that soft costs in the US are some of the highest globally, representing 60–70% of the total cost of residential-scale solar PV systems. Based on data like these, it is no surprise that solar industry stakeholders have a collective and often self-reinforcing perception that a solar PV system’s soft costs are perpetually stubborn. This whitepaper explores opportunities to reduce soft costs in residential-scale systems in the US solar market by streamlining and optimizing the solar sales process and business operations and workflow. Many opportunities to mitigate individual soft costs presented here also apply to small commercial systems.
