This young couple moved into their new home in the summer of 2020. The house came with 18 commercial panels for a total of 6.21 kW. After almost a full year of consumption, their true-up (annual) bill was close to $2,000. Realizing this was more than they expected or wanted to pay, they asked SolarEdge for a referral and were sent our way!
After assessing their energy usage and taking into account some heavy shading from a beautiful tree they preferred not to cut down, we determined that we could add nine more commercial panels (Hyundai 380W). Normally, we don’t recommend commercial panels for residential use, but we wanted the system to look uniform and this also allowed us to re-use their original racking system, saving on cost. We decided to reconfigure all of the panels in order to keep the new panels in full sun, maximizing their output. With the added panels, we also needed to upgrade their inverter size to handle the extra load, which required re-wiring of the system. All that said and done, it took only two weeks from start to finish!
We predicted that the addition would cover a little more than 70% of their current bill. They will save over $1,200 in just the first year! That means that, after receiving their 30% tax credit, they can expect their return on investment in just five years.
