Even the most experienced professionals make mistakes, and PV systems present many opportunities for errors. In this paper we list some of the more common issues we’ve seen or heard about often enough to be worth mentioning.
There’s no debating the values battery storage adds to a solar PV system, but conventional approaches to solar-plus-storage have been far too complex and costly. With new, increased demand for smart battery technology, installers need an easier option to offer customers who want batteries with their PV.
In this white paper from Pika Energy, you’ll learn about a new approach that simplifies solar-plus-storage, making it smarter, more affordable, more powerful, and ready for mainstream adoption.

Why did the industry move from 600-V to 1000-V solar arrays? The answer is simple: to reduce system costs. The value of increased system voltages is realized in infrastructure savings, reduced installation costs and end-to-end efficiency improvements. That is the same reason the industry is now moving from 1000 volt systems to 1500 volt systems. Learn more about challenges to the step-up, efficiency and cost considerations and why the move to higher voltages is so important to the industry overall.
In the age of data, solar contractors, maintenance crews and system owners can see more system performance details than ever. But collecting and analyzing too much data can be a waste of resources. So what is the ideal granularity for a PV installation? In this whitepaper, HiQ Solar examines a number of monitoring, O&M and safety aspects — Find the right balance…
Explore three case studies which compare costs between inverters in commercial rooftop systems of varying sizes and three-phase voltages. Learn how the installer saved with HIQ inverters based on real bids that were submitted last year in California.
Additional AC and DC disconnects add cost and complexity to PV systems and introduce several points of potential failure, thus reducing reliability. In the US disconnecting means are mandated by the governing electrical code. Several cents/Watt can often be saved in installation cost if separate disconnect boxes can be avoided in favor of integrated disconnects used by inverter manufacturers such as HiQ and Enphase. But is this code compliant? This paper addresses the regulatory requirements governing disconnecting means required for the replacement and servicing of PV inverter equipment. Specifically, the use of connecters as the required means of disconnect is detailed. It then shows that HiQ Solar TrueString™ inverters have been tested as part of their certification to allow this.
The ability of a PV inverter to detect and interrupt series arcs is a useful safety feature. In the US the National Electrical Code requires PV systems to be capable of detecting high voltage DC arcs. However, this has been a controversial topic. We’ll take a brief look at the issues with arc detection, and the progress being made in changing test methods to improve the situation.
