How the system builder works

Enter your monthly bill or pick a goal — lower my bill, bill savings plus backup, or fully off-grid — and the builder suggests a starting system size. From there you choose the actual panel, inverter, battery, mounting, and add-ons, and the price range and estimated payback update live. A compatibility check flags mismatched parts, like a grid-tied inverter with no battery support, before you request quotes.

Not sure what size you need first? Start with the guide to sizing a system from your bill, or read up on grid-tied vs hybrid vs off-grid solar before choosing an inverter type. Once you have a build you like, browse brand reviews for the components you picked, or submit it for free installer quotes.

Solar system builder FAQ

Frequently asked questions

How does the solar system builder work?

Start from your monthly bill or a preset goal, then pick real panels, an inverter, and (if you want backup) a battery from parts actually sold in the Philippines. The builder checks that your picks are compatible, totals a price range as you go, and estimates payback.

Are these real products and prices?

Yes. Every component is a real panel, inverter, battery, or mounting option with Philippine market pricing, not a generic placeholder. The total is a price range because installer labor, roof type, and brand vary the final quote.

What if I pick parts that do not work together?

The builder flags mismatches as you go, for example a grid-tied inverter paired with a battery, or a battery capacity too small for your backup goal. Fix the flagged issue before requesting quotes.

Can I save or share my build?

Yes. Your build is saved to the page URL, so you can copy the link, reload it later, or send it to someone else and it opens with the same selections.

Is the price and payback shown here final?

No. It is an indicative estimate for planning, not a quote. Final sizing, load calculations, and pricing should come from a licensed Professional Electrical Engineer (PEE) or installer who has seen your roof and electrical panel.

This builder gives an indicative price and size estimate for planning purposes only. Final system sizing, load calculations, and pricing should be confirmed by a licensed Professional Electrical Engineer (PEE) or installer based on your actual roof, panel, and electrical load.
