About Us

BurjCalc started with a simple frustration: every “free” construction calculator online seemed to come with a catch — a forced signup, an email wall, a flood of pop-up ads, or units that only worked if you happened to live in the right country. We wanted something simpler: open a tool, enter your numbers, get an accurate answer, and get back to the job.
So that’s exactly what we built.

What We Do

BurjCalc is a free library of precision calculators for homeowners, DIYers, and contractors. We started with Solar — Panel Angle, Cable Size, and Charge Controller calculators — because solar sizing mistakes are expensive and, in some cases, dangerous. From there, we’re expanding into Pool, Barns, Sheds, and more construction categories, with new tools added regularly.
Every calculator on BurjCalc is built around three simple rules:
  • 1
    🇺🇸 Imperial & Metric, Always
    Every tool has a built-in unit toggle. Whether you’re working in feet and inches across the US, or metres and millimetres in the UK, Australia, or Canada, you get accurate results without doing the conversion math yourself.
  • 2
    ⚡ Instant Results, Zero Signup
    No account. No email address. No credit card. Enter your numbers, hit calculate, and get your answer in under a second — every single time.
  • 3
    📱 Built for the Job Site
    Big, thumb-friendly buttons and a clean layout that works on your phone in direct sunlight, on a tablet in the truck, or on a laptop at the office. No app to install, no login to remember.

Who We Build For

BurjCalc is used by homeowners planning their first DIY solar setup, contractors who need a quick second opinion on-site, and tradespeople across the US, UK, Australia, and Canada who are tired of calculators that only work for one country’s units. We’re proud that our tools are now trusted by 50,000+ homeowners and contractors and counting.

Our Promise

Every calculator we publish is built on standard, well-documented industry formulas — not guesswork. We test our tools across both unit systems before they go live, and we keep improving them based on feedback from real users on real job sites.
⚠️ Disclaimer: BurjCalc is a free estimating tool, not a licensed contractor, engineer, or electrician. Our calculators are designed to give you a fast, reliable starting point — but for anything safety-critical (especially electrical and solar sizing), we always recommend a final check from a licensed professional in your area. You can read more in our Disclaimer.

How We Stay Free

BurjCalc will always be free to use — no paywalls, no premium tier, no signup required. To keep it that way, some pages include links to relevant materials on Amazon. If you click through and make a purchase, we may earn a small commission at no extra cost to you. It never affects which products we link to or the accuracy of our calculators. Full details are in our Amazon Affiliate Disclosure.
