All About the Humble Solar Panel

The Philippines has only two seasons: rainy and dry season. The rainy period occurs from June to November, during which the country can experience an average of 19 to 20 tropical typhoons. The dry period occurs from December to May, with summer happening from March to May. Take advantage of this period by having Solar Panels installed for your home. For sure you’ll generate a generous amount of energy you can use even on the wettest of days. Wait a sec, what is a solar panel? How does it work? Let’s find out the dynamics of one of the most wonderful innovations man has created.


A Solar Panel is a collection of solar cells fixed in a grid pattern. These solar cells, also known as photovoltaic cells, can convert the sun's rays into electricity. This process is called a photovoltaic effect as there is a physical and chemical change happening at the same time. During the day, these cells absorb and convert the sunlight. At night, you can use the energy generated around your home; one question though: how?

How It Works

Each solar cell is sandwiched between two sliced of semi conducting material such as silicon. These semi-conductant layers are mixed with other chemicals, allowing them to generate wither a positive or negative charge. For the top layer, phosphorus is usually used to give it a negative charge while the bottom layer is treated with boron to give it a positive charge.

Sunlight is composed of potons. Once these tiny particles hit the silicon layer, it sets free an electron, which will then be pushed out of the silicon by an electric field. Thanks to metal conductive sells on the sides of each cell, the electrons can be collected and transferred to wires. There you have it, solar energy.

On rainy days or at nighttime, you may be receiving a lessened amount of energy or you may resort to connecting back to the electrical grid just to get some electricity. Here's where solar electricity storage comes in. You can store is via either battery banks or grid inter-tie.

As for the energy produced, it all depends on the efficiency of the solar cells, size and number of solar panels and the amount of sunlight produced. For example, if you have ten panels, you may have around two kilowatt hours stored.


Some may think solar panels are purely for business establishments when in fact, they are widely used in homes with a steady supply of renewable energy. In the Philippines, it would be a great option because, as mentioned earlier, half of the year the country experiences the dry season where the sun is out and brightly shinning on our heads. It's also a more feasible source than other renewable sources, especially if one is living in the city.

You can even save a lot of money with your solar energy. Just check with your local electricity provider to see if they have any renewable energy programs. It’s also advantageous to other users on the grid as they get to use the excess energy your give back. These electricity providers do this in compliance with a law called the Renewable Energy Act of 2008. In it, a homeowner can have up to 100 kilo-Watt peak of installed solar panels under net metering. Isn't that great?

Solar panels are also environmentally friendly as they do not produce any harmful fumes as all you need to produce energy are the sun and the panels. In addition, you no longer have to rely on fossil fuels to get energy for your home. While fossil fuels are a non-renewable energy, solar isn't, allowing you to have an eternal supply.

Solar panels may be expensive at first, but for sure you will save a lot of money in the long run if you stick to using it.
