How Does Solar Work?

Our Planet Earth has clean resources that we can harness safely and environmentally, such as sunlight that shines above us every day.  Advancement in technology has aided us in converting that solar power to electricity. Solar is one of the best sources of clean renewable energy since it lessens the carbon footprint of consumers. It is a good way on how people can eliminate our dependence on fossils fuel and saves money at the same time!

What are Solar Panels?

The first components in order to collect light from the sun that is used on our loads are solar cells. When these solar cells are connected to form a larger component called “solar panels”. Then solar panels are connected to form another larger system called a “solar panel array” that is usually connected in series for more power output.

Each solar cell is composed of layers of silicon, phosphorus, and boron. When the photons are absorbed, they knock out the electrons from their orbit and drives directly to the current called the photovoltaic effect.

The most common type of solar panels:

Polycrystalline solar panels – these solar panels are commonly addressed to be slightly less efficient than monocrystalline panels. But it is cheaper for its less cost in producing its components. Usually recommended for facilities with a lot of roof space and after for its budget-wise pricing.

Monocrystalline solar panels – when it comes to efficiency, these panels are the right choice. It consumes less space on your roofing or its efficiency per square meter is an advantage. But they cost more than polycrystalline panels in exchange for its power production. This type of panel usually comes with a black color compared to poly panels with a blue color.

Solar panels today are designed to provide more power with less consumption on roof spacing or per square meter.

How does Solar Inverter work?

Wondering how can we utilize energy from solar panel arrays? A solar inverter is one of the most important components of a solar system. It converts the variable direct current (DC) output from the solar panel into steady alternating current (AC). Usually, most of the appliances at home in the Philippines use 240 V alternating current and cannot operate using direct current from solar without the use of an inverter.

Solar Inverters can be classified depending on the following systems to be installed:

Grid-Tied System – system connected to the electric utility grid that eliminates the large electric bill. The first priority of this system is to provide solar power for home consumption then with automatic transition, the grid will either shoulder up the shortcomings of the solar or export surplus energy back into the grid. If you intend to save on electricity this system is the best option for it can be applied for “Net Metering” or the process of selling the excess power produced by the panels back to the utility and the power utility grid will credit you for this. However, this system shuts down when the grid shuts down to void exporting and harming any linesmen repairing the commercial supply lines.

Off-Grid System – A separate power supply that can energize selected loads which are recommended for facilities that experience constant power interruptions. It can provide power when the grid shuts down since this system contains solar batteries that are charged up during the day.

Hybrid System – Combination of Grid Tie and Off-Grid System. The system is also connected to the grid and it has a battery backup for power interruption. Since the hybrid system has a grid connection, it can also be applied for “Net Metering” which the excess power can either be used to charge the battery or to be exported to serve as credits. These systems tend to be higher priced, but you do not have to worry about Typhoon power outages!
