Our Story
Why we built this
Most "solar calculators" available to Filipino homeowners are lead-generation forms in disguise: enter your bill, get a phone call. We wanted something you could actually use on your own: enter your Meralco (or VECO, or DLPC) bill and immediately see a realistic system size, cost range, and payback estimate, with the full reasoning shown, not hidden behind a sales call.
That grew into a research library covering the questions that come up once someone is actually serious about solar in the Philippines: net metering paperwork, typhoon-proofing, LiFePO4 vs. lead-acid, and the DIY safety details that most guides skip. We also maintain a catalog of solar equipment so you can compare real options once you know what you need.

"Grabe yung savings ng Meralco bill ko after nag-install ng solar. Yung calculator dito ang nagtulak sa akin na mag-decide talaga."
Janette Villanueva
Davao City
"Bago ko nag-install, nagbasa ako ng guide nila about net metering. Mas malinaw sa akin ngayon kung paano mag-apply sa Davao Light."
Bong Alcaraz
Quezon City
"Yung bill breakdown guide nila ang pinaka-useful sa akin. Real talk, di ako nag-aral ng electrical engineering pero naintindihan ko pa rin."
Rica Mendoza
Laguna
"Ginamit ko yung calculator para i-check kung magkano ang kailangan kong panels para sa 3BR house ko. Tama naman yung estimate!"
Kuya Jun
Batangas
"Matagal akong nag-iinstall ng solar para sa clients ko. Yung safety tips dito ay legit, lalo na yung part about backfeed."
Ate Lorna

"Nag-off-grid kami sa bukid kasi lagi kaming may brownout. Yung guide nila about batteries ang nag-save sa akin from buying wrong specs."
