The $2,000 plug-in solar system installed on Dwyer’s backyard deck in March consists of two 400 watt panels, an inverter, a smart meter and a circuit breaker. It saves him around $35 per month on his power bill because he is consuming less energy from the grid, but he said reducing his carbon footprint was his primary motivation.

2000$ is insanely expensive. It will take forever to pay for itself at that price. You can buy a kit like this for 300€ in Germany which will give you 100% ROI after a year.
