Is Residential Rooftop Photovoltaic Solar Power a Sustainable Solution?
Presenter: Stephen “Steve” Kujak

Solar power generation using photovoltaic (PV) panels continues to be one of the fastest growing renewable energy sources. In fact, many characterize capturing energy through PV panels as inexhaustible and sustainable energy source that is reliable for the long term, which is cost effective, efficient and is non-polluting. Unfortunately, sustainability means more than generating energy without the consequences of generating greenhouse gases from the burning of fossil fuel. The concept of sustainability is composed of environmental, economic and social impacts.

The presenter installed a 13 kilowatt fixed mounted residential rooftop PV system in June 2018. The system is comprised of 42 – 310 watt panels controlled by 21 micro-inverters. PV systems are marketed as a turn-key installations, easy to maintain and they have matured to the point of being just appliances without the need for monitoring. However, this is far from the case.

The presentation will cover the challenges and performance of this PV system for the past 18 months. It will cover challenges with system selection, installation and summarize both electrical generation and economic performance as well as the trials and tribulations. In the end, the audience will understand whether residential rooftop PV solar energy is sustainable. Many might be surprised by the answer.
