Solar energy is a smart energy solution that is replacing traditional energy resources. It is a common myth that solar panels can only be installed on slanted roofs, and that they do not receive enough energy from the sun on flat roofs. However, there are many ways in which you can install solar panels on a flat roof as well. Many people are choosing to have solar panels installed even while having a flat roof. So, if you are one of them and are thinking about installing solar panels on your flat roof, there are some considerations you must keep in mind. This blog post mentions some pointers to help you effectively have solar panels installed on your flat roof.
Know Different Methods Of Installing Solar Panels On A Flat Roof
Solar panel installation on a flat roof doesn’t only involve one method of installation. Instead, there are three ways to install it, and the common goal of each method is to get enough sunlight. The three methods of solar panel installation on a flat roof are:
- Attached Type
- Ballasted Type
- Footing or Foundation Type
The attached type of installation is where the solar panels have access to maximum solar energy, however, they experience high wind speeds. To deal with this, the panels are installed tightly. Hence, overall, it proves to be costlier than other methods.
The ballasted type uses a racking system for solar panels. You enjoy a quick solar panel installation procedure with this method as there is no drilling or anchoring involved in this process.
Footing or foundation type uses concrete slabs as footings for solar panel racking. The main aim of these footings is to make the foundation strong for stormy weather. Foundation type is helpful when the condition of the roof is not good, or you don’t want to tamper with the waterproofing insurance of the roof.
Consider The Wind Speed
If you live in a high windy area with frequent gusts of wind, you must consider a strong type of solar panel installation on flat roofs. A normal flat roof solar panel system can withstand wind speeds of up to 160 km/hr. Fixing panels to the structure or adding weights to them are the two most common strategies used for it. For this, a ballasted type or footing type are suitable. You might also need to increase the width of structural profiles for such windy conditions.
Check That Your Panels Are Receiving Optimal Amounts Of Energy
Solar panels that receive a good amount of energy will be able to deliver the electricity you need. For this, make sure your panels are at an ideal tilt angle and are getting enough sunlight every day. The solar panel professionals will draw a layout first and then begin the installation. Installers will use an A-frame to set the angle of the solar panels. Usually, the angle is set between 20-50 degrees in order to receive maximum sunlight.
Consider Water Leaks
On a flat roof, water tends to sit until it is drained gradually. This increases the chances of water damage and leaks on the roof. Adding solar panels to the roof adds to its danger, so you must be prepared properly. Your solar panel installer must be experienced enough to check the racking standards and make sure all holes are sealed and waterproofed. Moreover, consider any mechanical items installed on your roof, such as your AC, water tanks, or vents. Considering them is important when designing a racking system.
