Building The Right Roof for A Rooftop Solar PV System
More and more people are now going towards green energy. By going solar, a household can save up to 60% of its electricity bill. This also helps the environment from climate change by lessening the carbon footprint.
But before a homeowner decides to install a solar PV system, there are a lot of factors that need to be taken into consideration such as: costing, savings, the return of investment, and roofing! Installing a solar panel system is a long-term investment. The lifespan of a solar panel is 30 to 40 years, which is why as a homeowner, you would want to ensure that you are making the most out of your investment.
Some people consult with solar experts before constructing their house to make sure that everything is well planned. Today, we will share some tips to consider before building your home, particularly your roofing!
Direction – The direction of the panels affects the performance of the PV system. It is best to install your panels so that they are south facing. This will help your system perform better and harvest more energy. If you can’t get a south-facing direction, you can consider installing east or west-facing panels. It is best to avoid installing in a north-facing direction as it is the least effective in generating energy.
Shading – When you are planning to get a solar panel system for your home, consider the shading in your area created by high-rise buildings, mid-rise condominiums, and trees. A minimal shading can affect the entire performance of your system, which you don’t really want to happen. It’s best if there is no shading in your area.
Roof Condition – Another important factor to consider is the condition of your roof. It should be strong enough to withstand a 22 kg panel. Check also if there are any damages or water leaks that need to be repaired before the installation. You wouldn’t want to pay extra costs to dismantle your system simply to fix a structural flaw in your roof.
Roof Space – Your energy consumption is not the only deciding factor for your system size. In fact your roof space also dictates how many panels you can install on your home. A household with a 3,000 pesos electricity bill can install a capacity of 6 panels that requires 15 square meters of roof space. You can’t achieve your desired savings if your roof space is limited and cannot accommodate the required number panels based on your energy consumption. The bigger the roof space you have, the more panels you can install. Check our rooftop calculator to determine the number of panels that you can install.
Roof Type – Metal roofing are best paired with a solar panel installation. They offer a solid surface and long-term durability for panels. It is more secured and can last about 40 years. Since they often contain large amounts of recycled aluminum, metal roofs are one of the most sustainable roofing materials.
The material of your roof has a big impact on how much energy is being absorbed by your panels. The more heat that is absorbed, the lower the efficiency of your panels, contributing to higher system losses.
Your roof is your asset! And that is the key to good energy production. It is important to consult with your solar provider before installing a solar panel system for your home. Ready your roof and make the switch to solar now!
