WattAttack

WattAttack started with a simple frustration: finding out what solar costs shouldn't require sitting through a sales pitch. Ask an installer and you get a quote designed to close a deal. Search online and you get generic calculators built for other countries' roofs, prices, and sunlight.

So we built the tool we wished existed. Upload a photo of your electricity bill and WattAttack does the rest. It reads your consumption, checks the actual sunlight, and designs a system around your real usage: panels, inverter, batteries if you want them, every component priced in pesos from a live catalog. You'll see when the system pays for itself, honest warnings if something looks off, and a printable electrical blueprint you can hand to any installer.

It's free and you don't need an account. Your bill is analyzed and then forgotten, no data hoarding.
