I recently decided to set up a solar system for my work-from-home setup, which includes a 15" laptop, a 27" monitor, and my phone. I got two power stations, each with 512Wh capacity, and a 100W folding solar panel. The plan was to charge one power station with solar while using the other for work, then swap them out the next day. So far, everything is running smoothly on solar power, and it cost me about C$775 with sales included. However, I calculated my savings, and it's only around 8 to 10 cents per day—about C$3 to $4 per month. This translates to a rough 20-year ROI if nothing breaks. Given that my local electricity rate is only about 9 cents/kWh from hydro power, I'm starting to wonder if solar energy is just a feel-good hobby for those connected to the grid. Do you think solar is only effective in areas with high electricity costs or for off-grid situations? Is there a better method I could have used? I'm looking for perspectives that might restore my faith in pursuing solar energy!

In areas with low-cost electric like yours, going solar might not make financial sense if you’re just looking to save money. I spent around $5000 on a bigger system that pretty much pays for itself in a couple of years, but that’s because my electricity prices are significantly higher. If your goal is energy independence or reliability, then yes, solar has its perks even in grid-connected homes. But for savings? Probably not with your rates.
You definitely paid a premium for your folding solar panels compared to standard rigid panels. While your system seems less efficient cost-wise due to your local power rates, it can make sense if you're looking for reliability during outages, especially with something like a large off-grid setup. But yeah, small portable systems just won’t give you much ROI in your situation.
You’ve got super cheap electricity where you are, so it’s not surprising that solar might not yield significant savings for you. At best, it could serve as a backup system in case of grid outages. Plus, even if it does feel more like a hobby, you’re still gaining valuable experience and skills along the way.
