Our Mission
Empowering the Solar Industry, One Calculation at a Time
We believe that powerful solar analytics shouldn't come with a price tag—or compromise your plant data privacy.
Kindastuff Solar Analytics was born from a simple frustration: why should solar professionals struggle with expensive software, complicated setups, or tools that demand you upload sensitive plant data to unknown servers?
We built something different. A platform where every calculation happens right in your browser. Where your plant data stays on your device. Where "free" actually means free—no hidden catches, no premium tiers, no "contact sales for pricing."
Whether you're an O&M engineer troubleshooting in the field, an asset manager reviewing quarterly performance, or a student learning the fundamentals of PV analysis—you deserve tools that just work.

Meet the Creator
Aman Yadav
Renewable Energy Engineer & Founder
I'm a B.Tech Electronics & Instrumentation engineer from Medicaps Institute of Technology with 8+ years of hands-on experience in solar plant operations. Before founding Kindastuff, I worked as a Solar Plant Performance Engineer in the O&M department of a 30 MW ground-mounted plant in Madhya Pradesh — responsible for daily SCADA monitoring, monthly MIS reporting, PR and CUF analysis, client performance reporting, and fault rectification.
The tools on this site are the ones I needed on the job and couldn't find for free. Every calculator reflects a real calculation I ran in a real reporting cycle — not a textbook exercise.
"If a tool is genuinely useful, it should be accessible to everyone—not just those with enterprise budgets."
FAQs
Common Questions
Is my solar data safe with Kindastuff?
Yes. All solar calculations run 100% locally in your browser. Your plant data never touches our servers and never gets uploaded. The values you enter into our calculators stay entirely on your device.
Are these tools really free? What's the catch?
There's no catch. Kindastuff is free because we believe essential industry tools shouldn't be locked behind paywalls. We sustain the platform through minimal, non-intrusive advertising. No premium tiers, no "contact sales," no sudden pricing changes.

Yes! Install Kindastuff as a Progressive Web App (PWA) on your device. Once installed, you can access all calculators without an internet connection—perfect for remote site visits or areas with poor connectivity.
How accurate are the calculations?
Our calculations follow industry-standard methodologies used in professional PV performance analysis. Computational accuracy is exact; real-world accuracy depends on sensor calibration and data quality.
