Straight answers
Solar questions,
made simple.
Clear guidance before you make a decision. Every final recommendation is still verified against your property, electricity use, and equipment needs.
Ask us something else →01Will solar completely eliminate my bill?+
Not always. A well-sized system can greatly reduce the energy portion of your bill, but fixed utility charges, nighttime use, weather, shading, and the value of net-metering credits can leave a remaining amount. We design toward a realistic reduction target—not a guaranteed zero bill.
02Does solar work during brownouts?+
A standard grid-tied system shuts down during a brownout to protect utility workers and equipment. If you need backup power, a properly designed hybrid inverter and battery system can keep selected essential loads running, subject to its capacity.
03Do I need batteries?+
Not necessarily. Batteries are most useful when you need brownout protection or want to use stored solar energy at night. If most electricity is used during sunny hours and backup is not a priority, a grid-tied system may be the more economical starting point.
04What is net metering?+
Net metering is a program that lets an approved renewable-energy system send unused electricity to the distribution grid through a bidirectional meter. The corresponding export value is credited to your bill under your utility's rules. In the Philippines, the standard program covers eligible systems up to 100 kW; application and approval are required.
05Can solar power an air conditioner?+
Yes. Solar can help power air conditioners, but the system must be sized for the unit's consumption, operating hours, and starting demand. Daytime operation is usually the easiest to offset directly; nighttime air-conditioning may require batteries or grid power.
06How long does installation take?+
On-site installation for a straightforward home system often takes several working days. Larger or more complex projects take longer. The complete schedule also depends on the site survey, structural and electrical preparation, equipment availability, permits, testing, and any utility or net-metering process.
07How many panels fit on my roof?+
It depends on usable roof area, orientation, shade, roof shape, setbacks, and safe access paths. Our estimator uses a preliminary allowance based on a 620 W panel measuring about 2.382 m × 1.134 m, plus 10% for spacing and access. A site survey confirms the final layout.
08What warranties are included?+
Warranty coverage depends on the selected panels, inverter, batteries, and installation scope. Your proposal will identify the applicable manufacturer product and performance warranties together with SilanganTech's workmanship and support terms, so you can review them before approving the project.
09Does SilanganTech provide maintenance?+
Yes. SilanganTech provides after-sales support and can assist with system inspection, performance checks, troubleshooting, and maintenance planning. The recommended schedule and scope depend on the equipment, site conditions, and system type.
