TYPES OF SOLAR ENERGY SYSTEMS
Grid-Tied Solar
-
Connected to the power grid, it uses solar energy during the day and switches to grid power when solar is insufficient.
-
Excess energy is sent to the grid, and batteries are not required.
-
Offers the best return on investment (ROI) in terms of years (payback period):
-
2–4 years if energy usage is high during the day.
-
4–10 years if daytime usage is minimal (e.g., working outside on weekdays).
-
-
Net Metering:
-
Allows excess solar energy to be sent to the grid in exchange for credits, reducing your electricity bill.
-
Utility providers buy back energy at less than half the selling rate (e.g., sell at ₱13/kWh, buy back at ₱5/kWh).
-
Battery (Hybrid) Solar
-
Combines solar panels, batteries, and the grid.
-
Stores excess solar energy for later use and provides backup during outages.
-
More expensive, with an ROI in terms of years or a payback period of 10+ years due to the limited lifespan of lithium batteries (about 10 years).
Off-Grid Solar
-
Fully independent from the grid, relying solely on solar panels and batteries for power.
-
Ideal for remote areas but requires careful planning to ensure uninterrupted electricity.

Net Metering is not yet included (PhP40,000.00)
Net Metering is a system that allows solar power users to send excess electricity they generate back to the utility grid in exchange for credits. These credits can offset electricity costs when energy consumption exceeds production, such as during the night.
The cost of setting up Net Metering is an additional ₱40,000. It is highly advantageous for households or businesses that produce surplus energy during the day or primarily use electricity at night, as it helps maximize the benefits of a solar power system.
However, installing a solar power system is not advisable if your electricity usage is mostly at night. Utility companies buy excess electricity at approximately ₱5/kWh, which is less than half the rate they sell it. As a result, the payback period (ROI) becomes longer, typically ranging from 7 to 15 years to recover your initial investment.
