Solar energy is the most reliable form of renewable energy. Solar panels have photovoltaic cells (PV cells) that convert the sun rays into electricity. You have to know the factors and the best conditions for the solar panel to generate electricity.

Factors Affecting the Solar Panel

  • The positioning of the panel – The solar panel is designed to absorb much sun rays to generate more electricity. The placement of the solar panel must be ensured that it gets the maximum amount of sunlight possible.
  • The direction of the roof – One important factor affecting the performance of the solar panel is the direction of the roof where it is to be installed. The roof must be facing south in order to achieve maximum efficiency. If your roof is facing east or west, don’t worry. Studies show that solar panels facing east or west have only 15% less electricity generation than those facing south. It is still plenty enough to provide power for your house and a return on investment.
  • The angle of the solar panel – The solar panel must be mounted with an angle of 30 to 60 degrees from horizontal to get its optimum efficiency. If your roof is flat, consider putting an angled mounting bracket to ensure that the solar panels get the maximum amount of sunlight. When the sun is high in the sky, especially during summer, the angle of the solar panel must only be 30 degrees. During rainy season or when the sun is lower in the sky, the solar panel must be placed around 60 degrees. Having the same angle of the solar panel throughout the year or changing it depending on the season won’t give big difference, though.

What are the best conditions for generating solar energy in the Philippines?

Weather condition – The best weather condition is when the day is clear and bright. The solar panel reaches its optimal output during this time because the maximum amount of light can penetrate it and it can then produce electricity. The solar panel needs light from the sun, not heat. That is the reason why the solar panel generates more solar energy in clear, non-cloudy days than in warm days. Regular amounts of rainfall do not really affect the output of solar panels; instead, these can clean the panels from dust and dirt. This can also help keep the solar panels cool which can be beneficial to its efficiency. During cloudy days, the solar panel generates only one-third of their maximum output; hence, it is the time that the production is least optimal.

Time of year – During the dry season, generally, from December to May, the country is experiencing moderate to high temperature and less rainfall. There is also an abundant amount of solar power during this season. Having a long dry season of about 6 months, one problem that may arise is experiencing high temperature in the months described as the hot dry season, March to May, because too much heat would diminish the performance of the solar panel.

Type of solar panel – It is said that the most efficient solar panel is the most expensive, monocrystalline type. Today, there are many varieties of solar panels, from monocrystalline to polycrystalline type. Solar Panel Philippines have these variations added to supreme quality products. They are a trusted supplier and distributor of solar panels in the Philippines, not to mention their contribution to Germany’s solar panel distribution. So what are you waiting for? Contact us.
