Curious about what happens to your solar panels after dark? At Solaready, a leader among solar energy companies in the Philippines, we often receive this question from homeowners and businesses eager to understand how their solar panels in the Philippines continue providing benefits when the sun goes down. Let’s explore how solar panels function at night and the role of battery storage and grid-tied systems in ensuring your home has power 24/7.
Solar Panels: Daytime Energy Harvesting
Solar panels capture sunlight during the day using photovoltaic (PV) cells, which convert sunlight into direct current (DC) electricity. This energy is then converted into alternating current (AC) via an inverter for use in your home. But what happens when the sun sets, and there is no sunlight to generate electricity?
Solar Panels at Night: How They Continue to Power Your Home
At night, solar panels in the Philippines no longer generate electricity. However, there are two primary ways to ensure that your home stays powered when it's dark outside:
1. Battery Storage Systems
Battery storage is a popular solution that allows homeowners to store excess energy generated during the day and use it at night. This energy independence is especially useful for homes and businesses in areas where the grid may be unreliable or costly.
In the Philippines, solar battery storage systems such as Tesla Powerwall, LG Chem, and SonnenBatterie are growing in popularity as more Filipinos seek out clean energy solutions to reduce electricity costs. Battery storage systems ensure that your solar energy continues to provide power, even after sunset.
2. Grid-Tied Systems with Net Metering
Another popular option is a grid-tied solar system. In this setup, any excess energy generated by your solar panels during the day is sent back to the grid. At night, your home can pull electricity from the grid, ensuring you have power without the need for an expensive battery storage system. With net metering in the Philippines, you can even earn credits for the excess electricity your system produces, reducing your overall electricity costs.
This system is especially beneficial in sunny areas, where solar energy production during the day is high. Your solar panels in the Philippines may generate more energy than you need during the day, and with net metering, that surplus helps lower your nighttime electricity bill.
Solar Energy Data in the Philippines
According to the Philippine Department of Energy's Renewable Energy Plan, the country is committed to increasing the share of renewable energy in its energy mix. In 2022, solar energy companies in the Philippines contributed approximately 1,370 MW to the national grid. In growing cities like Alabang, solar power is becoming more accessible, and the sunny weather makes it a smart investment for homes and businesses alike.
Additionally, the cost of solar battery storage has significantly decreased—by about 85% since 2010. This makes going off-grid or storing energy more affordable for homeowners in the Philippines.
Why Solar Energy is a Smart Choice, Even at Night
Energy independence: With solar battery storage, you can power your home even when the grid goes down.
Cost savings: Net metering allows you to offset your nighttime electricity use with credits from the surplus energy your solar panels produce daily.
Environmental benefits: Using solar energy reduces your carbon footprint and helps the Philippines reach its renewable energy goals.
