Santa Cruz, Laguna · Residential solar
Solar na pinag-iisipan, hindi basta kinakabitan. Kasama si Kuya Watts, pag-usapan natin ung setup na bagay sa bahay, appliances, at priorities nyo.
FROM THE FIELD / WATT & WHEELS PH01 / Kilalanin si Kuya Watts
Ako si Francis “Kuya Watts” Natividad. Dala ko ang 13+ years na international experience sa ELV systems sa Qatar at Saudi Arabia sa maingat na pagplano at pag-uusap tungkol sa solar.
Xmpre, mgnda ung malinaw muna ang kailangan bago ang package. Hindi bill lng ang basehan, Boss. Titingnan din natin ung loads, roof, daytime usage, at gusto nyong backup.
DTI registered sa CALABARZON (W & W SOLAR PANEL INSTALLATION SERVICES), may Mayor’s Permit, at BIR compliant (Non-VAT, 8% Income Tax Option). Ang serbisyo at standards, pang-international. No hidden charges, transparent sa taxes.
02 / Hanapin ang starting point
Piliin ang pinakamalapit na bill at appliances nyo. Starting package lng ito, Bosing, hindi pa final system design o quotation.
Wla ung exact bill nyo? Pde piliin ang pinakamalapit, tapos i-note natin ung actual usage sa inquiry.
Suggested package to discuss
For a bill around ₱3,000–₱5,000, start the discussion with a 6 kW SG06-family inverter. Battery capacity is your separate selection, subject to a load and compatibility review.
Boss, about 7.2 hours sa 0.5 kW average load.
Halimbawa lng, hindi guaranteed. Fully charged, 20% battery reserve, and 90% AC conversion: 5 kWh × 0.72 ÷ 0.5 kW.
Hindi katumbas ng fixed 500 W ang 1 HP aircon. Actual aircon efficiency, cycling, other loads, starting charge, and BMS/inverter power limits matter. This battery-only example excludes PV recharging; weather and available solar affect real use. Exact battery capacity is subject to model.
No aircon listed.
This selector follows Watt & Wheels PH’s starting-package menu, not an engineering calculation. Inverter kW is not the solar-array kWp. Battery kWh is nominal, not guaranteed usable energy or backup runtime. Panel count, equipment compatibility, cable sizing, roof suitability, protection, cost, savings, and payback require a proper assessment.
03 / Our approach
Hindi kailangang pare-pareho ang system ng lahat. Bsta malinaw kung ano ang priority, mas maayos ang usapan.
Plan the battery around essential loads and the reserve you want to keep. Hindi ibig sabihin na lahat ng appliances ay pde sabay-sabay sa backup.
Backup capacity and runtime depend on loads, battery condition, state of charge, and system limits.Pag-usapan ang charging windows, discharge limits, at reserve settings. I-aayon ito sa exact inverter, battery, usage pattern, at tariff kung applicable.
A time schedule is not a promise of a lower electricity rate or guaranteed savings.EV charging is planned as a non-backup load: grid at night, and available daytime PV where the design allows. Water pumps need a separate starting-current review.
EV charging is not promised from the backup battery. Grid-side placement is a design decision, not a universal rule.04 / From the field
Roof work, equipment, at panel preparation. Tap a photo for a closer look. Walang stock project photos dito.
Photos provided by Watt & Wheels PH. Captions describe visible work only. No customer names, addresses, system ratings, or compliance certifications are inferred from the photos.
05 / Details matter
Model, load, protection, at installation conditions muna. Kya hindi tayo basta kumokopya ng settings o wire sizes sa ibang setup.
Family labels alone are not enough to compare units. Check the complete model code, voltage and phase, battery-current limits, PV input ratings, backup limits, firmware, and the matching manufacturer manual.
Cable sizes, protection, and terminal torque are selected for the exact equipment and site conditions, then verified during commissioning. Specifications belong in the approved installation design, not a one-size-fits-all checklist.
Follow the exact equipment manual and terminal rating. Size conductors and protection for current, run length, voltage drop, temperature, routing, and applicable local requirements. Qualified installer review required.
Plan dedicated runs for PV, battery, AC, and signal wiring where appropriate. Conduit sharing, insulation ratings, grounding, and protection must be reviewed by the responsible designer against the applicable requirements, not decided from a blanket rule.
06 / From usap to handover
Bill, city, daytime habits, and backup goals. No need to share account numbers or personal IDs.
Check roof, shade, electrical setup, actual appliances, and any special starting loads.
Confirm exact models, scope, applicable taxes included in the total, installation terms, and written warranty coverage.
Agree on installation, configuration, testing, monitoring access, and operating guidance before turnover.
07 / Tanong mo, sagot natin
Practical answers bago tayo mag-decide. Para alam nyo kung ano ang kasama at ano ang kailangan pang i-check.
A proposed 10-year arrangement: 5 years from Deye plus 5 years from Watt & Wheels, only where confirmed for the exact equipment and written agreement. This is not a claim of a 10-year manufacturer warranty. Coverage, exclusions, labor, transport, start dates, and claim process must be stated in writing.
Hindi, Boss. Savings depend on solar production, usage timing, tariff, shading, weather, system size, and settings. May grid consumption at other charges pa rin depende sa setup. We don’t promise zero bills or a fixed payback period.
Only the loads included in a compatible backup arrangement, within inverter and battery limits. Ordinary grid-tied solar alone generally does not provide power during a grid outage. Review essential loads and expected runtime before deciding.
Pde natin i-assess. A pump needs motor starting-current and protection checks; a compatible soft starter may be considered, but is not suitable for every motor. Grid-side placement may be proposed after review. For the 1.5 HP inverter aircon, check actual wattage, startup behavior, usage hours, and what else runs with it.
No. This starting concept keeps EV charging on a grid-side, non-backup circuit. Night charging uses the grid; daytime charging may use available PV depending on the electrical design and operating conditions. It is not promised during a brownout.
Our starting discussion prioritizes self-consumption, battery use, and backup reserve. Net metering can still be worth evaluating. Approval steps and timelines vary by distribution utility and project. For Meralco, zero-export systems still require utility notification and registration, and net-metering credits use its applicable monthly blended generation component, not the full retail rate. Confirm the current requirements of your own distribution utility before choosing.
The written quotation should show the total inclusive of applicable taxes and the agreed equipment, work, and exclusions. No fixed price is displayed until the site and scope are reviewed. Warranty is model- and agreement-specific: manufacturer coverage and any Watt & Wheels extension must be distinguished in writing.
A recent electricity bill with account details redacted, your city or municipality, roof photos if available, and a list of essential loads. Kung may pump, aircon, or EV charger, include the model or rating. No personal IDs needed for this inquiry.
