The best way to reach us is by email: [email protected].

We especially welcome:

• Corrections: if a number, formula or claim looks wrong, tell us which page and why. We review every correction and update the page if needed.
• Calculator ideas: tell us what you were trying to work out and couldn't.
• Real-world results: if your power station's actual runtime differed a lot from our estimate, the details help us improve the assumptions.

We usually reply within a few days. We can't give personalized electrical installation advice. For that, please contact a licensed electrician.
