Frequently Asked Questions
Technical guidance on hybrid battery storage, solar system sizing, warranties, and electrical engineering in the Philippines.
For residential hybrid systems with monthly electric bills between ₱10,000 to ₱35,000+, typical payback is 3.8 to 4.8 years, depending on daytime consumption and battery usage. Once paid off, your system produces free energy for the remainder of its 25-year panel lifecycle, shielding your household from ongoing utility rate hikes.
Our hybrid systems feature an automatic transfer switch. Your designated critical loads (refrigerators, WiFi routers, lighting circuits, and air conditioning units) continue operating uninterrupted powered by the LiFePO4 battery bank.
Lithium Iron Phosphate (LiFePO4) is the safest battery chemistry available, with exceptional thermal stability and zero risk of thermal runaway (fire). It delivers over 6,000 charge cycles at 80% Depth of Discharge—translating to 15+ years of daily cycling compared to only 2-3 years for lead-acid batteries.
Yes. System runtime depends on battery capacity and aircon horsepower. A standard 16 kWh LiFePO4 battery bank paired with our 6kW to 8kW hybrid inverter can comfortably power a 1.5 HP inverter split-type air conditioner (consuming ~600–800W once room temperature stabilizes) for 8 to 10 hours overnight alongside refrigerators and lighting.
We operate on direct, transparent turnkey pricing with zero bloated financing markups. We accept Cash, Manager's Checks, and Direct Bank Transfers / Wire to our corporate bank accounts (BDO, BPI, Metrobank, UnionBank). We do not offer in-house installment plans.
All Solar Spartz packages feature top-tier manufacturer warranties: Tier-1 N-Type TOPCon bifacial solar panels include a 10-year factory product warranty and up to 25 years linear power output guarantee; hybrid inverters include a 5-year standard replacement warranty; and LiFePO4 batteries come with a 5-year warranty. Solar Spartz backs the entire installation with a 1-year engineering workmanship warranty.
A Grid-Tie system relies entirely on the electrical grid frequency to operate; when the utility grid experiences a blackout, Philippine Electrical Code (PEC) anti-islanding regulations require grid-tie inverters to instantly shut down for utility worker safety. A Hybrid system includes smart bidirectional inverters and battery storage that safely disconnects from the grid, automatically creating an independent microgrid for your home.
We deploy turnkey residential hybrid solar systems across Greater Metro Manila (NCR) and key surrounding corridors including Cavite, Laguna, Batangas, Bulacan, and Pampanga.
Solar PV systems are solid-state with little to no moving parts, requiring minimal maintenance. In tropical climates, dust and grime are largely washed away by rains. We recommend a gentle water rinse every 6 months to maintain peak efficiency. All our installations include cloud-connected smart data loggers so our technical team can remotely monitor string voltage and daily production 24/7.
If your household runs 3 or more air conditioners simultaneously, our technical team recommends an 8kW to 10kW hybrid inverter paired with a minimum 16 kWh LiFePO4 battery bank. Air conditioning compressors produce high inrush starting currents, so our engineers size your system with ample surge headroom and staged startup protocols to ensure seamless cooling and zero voltage dips during grid power outages.
