Update on PV installations

With the increasing number of sales for solar panels in the Philippines, solar power is now becoming the most popular renewable energy source on a global scale. It is not just about reducing costs and saving money. Protecting the environment has become a top priority for the planet. Based on a study by IHS Markit, global PV installations are expected to reach a total of 34GW completed, in Q4 of this year alone. The market is expected to soar to double-digit growth. In 2019, there will be 11 million new connections to the internet of energy from solar systems existing in 2019. Yes, all regions of the globe are expecting growth in its solar PV installations for the year. In the United States in 2018, there were 2 million solar installations, and this is set to double in the next four years. In the Philippines, however, as of mid-year 2019, the numbers show that there are only a little over 2,100 net metered solar installations.

Why solar?

Why solar?

The number one reason that the general population is now installing solar panels is because it has become affordable and cost-effective. The cost of solar panels has decreased to more than 70% in the past decade. If you are environmentally aware and understand the benefits of clean, safe, sustainable and renewable energy, then now is the best time to consider installing solar panels on the roof of your home and business. The solar panel system will make your home or business energy efficient, reduce your carbon footprint, and increase the property value of your home or business. If you are thinking about installing rooftop solar, then you may have questions about whether solar panels can be installed on your roof type.

What kind of roof is good for solar?

Let us examine some important factors that determine whether you can install solar panels on your roof.

Age and condition of your roofAge and condition of your roof

It is critical to determine the condition of your current roof. It should be in good condition if you are going to install solar panels. Condition is different from the age of the roof. If your roof is more than five years old, then have a professional determine its current shape and condition, and see if it is ready for a solar panel system installation. If the roof is already near the end of its expected lifespan, then it may be wiser to replace it before installing solar panels. This ensures that the roof can support the solar panels. Solar panels typically have a warranty to 10 to 25 years and a life span of 25 years.

Material of Roofing

The roof type that is most compatible with solar panels is a flat roof or GI sheet roof. The material allows for easier installation. There are some roofing materials that are not ideal for solar panel system installations, such as wood and slate roofs because they are brittle.

Tilt of Roof

Tilt of roof

The tilt of the roof will determine the effect of energy production by your solar panel system. If the roof is too steep, such as over 40 degrees, then energy production and solar harvest is less. If the roof is flat, you can install solar panels and just have to use brackets to angle the panels.

Shape and Size of Roof

It is also important to consider the size and shape of your roof when thinking about installing a solar panel in the Philippines. A typical 5kWp solar panel installation will occupy about 30 square meters of surface area on the roof.

Shading and Sun Exposure

Shading and Sun Exposure

The amount of shading around your roof and the exposure of your roof to the sun can also affect the effectiveness of a solar panel system installation. There are instances when shade cannot be changed or removed, such as when your house is surrounded by buildings which block the sunlight on your roof. If your roof receives little or minimal sunlight, then rooftop solar or a solar panel system installation may not be the best option for you.
