Share your electricity use
Upload a bill photo or enter the monthly kWh printed on the bill.
What you need: one normal bill Solar planning, without the confusion
Plan your solar system before you buy it.
Start with a goal and one electricity bill. SolarLab explains the panels, inverter, optional battery, roof space, wiring, protection, build phases, and questions to ask before you spend money.

From one bill to a usable plan
How SolarLab helps you build a home solar plan
You do not need to know electrical terms. Follow the pictures and answer one small group of questions at a time.
Tell us about your home
Choose your goal, nearest location, roof length and roof width.
What you need: rough roof measurementsSee the starter setup
SolarLab estimates panels, inverter size, optional battery and generation.
What you get: a plain-language recommendationCheck roof and safety
Review panel fit, wires, breakers, fuses and equipment compatibility.
What you get: warnings before buyingReview build phases
Choose whether to build everything now or add solar and battery in stages.
What you get: a changeable phase planDownload your report
Export a homeowner summary, shopping baseline and technical handoff.
Final step: verify with qualified professionalsReady to start?Most people only need a bill and five minutes.
Build my starting plan What are you trying to do?
Choose a goal. SolarLab chooses the workflow.
You do not need to know which calculator to open first.
Reduce my electricity bill
Start with one normal bill and estimate the solar size needed to offset monthly use.
Start bill-saving planAdd backup power
Choose essential loads and backup hours, then coordinate the inverter and battery.
Plan battery backupBuild an off-grid system
Use more conservative solar and storage assumptions for weak or unavailable utility power.
Start off-grid planCheck what fits on my roof
Estimate panel count, visualise the roof area, and move overflow to another roof plane.
Open roof designerUpgrade an existing system
Check a known package size, future expansion, battery storage, and equipment limits.
Check an upgradeDesign it manually
Open the full connected workspace, wire tools, protection calculators, and simulator.
Open advanced tools See it, do not just calculate it
Every recommendation connects to a visual.
Watch panels fill the roof. See batteries grow with backup hours. Compare AC and DC conductor behaviour. Run minimum, mid, and peak-load simulations. SolarLab explains what changes and why.

Built for community review
Check a quote. Learn from a real build. Challenge the recommendation.
The Community Beta is designed to improve through real Philippine solar questions, installer feedback, and measured systems.
Installer Quote Checker
Turn a package quotation into a list of missing model numbers, safety details, expansion limits, and questions to ask.
Check a quote →Net Metering PH
Understand self-consumption, possible export, and the official utility process before counting export credits in payback.
Learn net metering →Real Solar Builds
See actual measured consumption, faults, configuration lessons, and phased expansion—not only equipment lists.
