About Us
Our Mission
At WattSizing, our mission is to make solar energy accessible and understandable for everyone. We believe that transitioning to renewable energy shouldn't require an engineering degree. By providing simple, accurate, and free tools, we empower homeowners, RV enthusiasts, and off-grid adventurers to confidently plan their solar setups.
Our Story
WattSizing was born out of frustration with the complex, confusing, and often misleading information available online about solar panel sizing. We saw a need for a straightforward, transparent calculator that gives users realistic estimates without hiding behind paywalls or requiring personal information upfront.
Our Expertise
Our team consists of renewable energy enthusiasts and software developers dedicated to providing accurate information. We base our calculations on:
- Standard industry practices for solar irradiance and system losses.
- Up-to-date component specifications and efficiency ratings.
- Real-world feedback from off-grid and grid-tied solar users.
Our Commitment to You
We are committed to keeping our core calculator free to use. We strive to provide unbiased informational content to help you navigate the transition to solar energy. While we may earn a commission through affiliate links on our site, our recommendations are always driven by quality and value for the user.
