Photovoltaic system with battery Philippines

Do solar batteries make sense in the Philippines?

Whereas every fifth solar energy system we install in Germany has a battery, there are only a few cases where solar batteries make sense in the Philippines and that can create many traps for end-customers! Yet we observe that solar batteries are offered to nearly every end-customer.

How much is 1kWh of solar energy worth in the Philippines?

1kWh of solar energy is worth PHP 9-11 in the Philippines. If the 1kWh is stored in a solar battery, it can only supply around 70% of the stored 1kWh back to your appliances due to physical losses. With net metering, a utility provider pays you the generation charge of up to PHP5.5 for each solar kWh sold back to the grid.

How much does a photovoltaic module cost?

The module price is currently between 20 PHP per watt. A typical monocrystalline photovoltaic module with an output of 350-450 watts currently costs 12k PHP to 21k PHP. With a 10-kilowatt peak system, there are around 500k PHP in pure module costs. If you opt for a polycrystalline or thin-film module, the costs will be 20-40 percent lower.

Do you need a smart meter for a photovoltaic system?

Without a smart meter, the photovoltaic system must be dynamically regulated at 70% of the nominal output. The smart meter records your self-consumption in real-time and can use up to 100% of the nominal power of your system (e.g., with 30% self-consumption and 70% feed-in). In a few years, smart meters will be mandatory for all households. 7.

What should be done before turning on a photovoltaic system?

Before turning on the system, following the tests and tests addressed in the Photovoltaic Systems commissioning standard and documenting the values obtained to verify compliance and compare them in future system maintenance is suggested. Indispensable tests. 9. Check if the inverter has SPDs, disconnect switches, and, if necessary, fuses.
