I built a free solar toolkit for anyone who isn’t sure whether going solar makes sense
Hey everyone,
I’ve been working on a free project called SolarPro Toolkit for people who are curious about solar but aren’t ready to talk to a salesperson or give out their phone number just to see some estimates.
You don’t need to download or install anything. The whole app runs in your browser through GitHub Pages. There’s no signup or tracking, and the calculations stay on your device.
It can help you:
- Estimate solar payback time, your potential new bill, and long-term savings
- See how long a battery could power your fridge, Wi-Fi, CPAP, and other essentials
- Compare the monthly cost of an EV with your current car
- Estimate home energy usage if you don’t have a bill handy
- Understand which parts of your electric bill solar can and can’t reduce
- Learn how time-of-use rates and NEM 1.0, 2.0, and 3.0 affect the numbers
I tried to keep the assumptions visible and editable. The California-style defaults are included, but you can change the numbers for your own situation. Sometimes the result says solar makes sense, and sometimes it says you’re better off keeping your money. That’s exactly what I wanted from it.
It’s mainly for homeowners doing early research, but it may also be useful for solar consultants who want a transparent way to explain the tradeoffs. Personal use is free. Commercial or consulting use requires a license, and I’m working on a Pro version for industry users.
This is still an estimate, not a quote or financial advice, so always confirm rates and incentives with your utility.
I’d really appreciate any feedback, especially if something is confusing or there’s a feature you’d want before making a solar decision.
