subject: How To Install Solar Panels On Flat Roofs [print this page] Among all alternative green energy sources, solar energy is known to be very effective. Most people are moving from 100% traditional energy sources to using green energy sources. Due to the fast depleting natural sources of energy, people are switching to greener alternatives. In states like Hawaii where energy is becoming very expensive, more and more folks are motivated to install solar panels for home and commercial purposes. Solar power is an ideal choice for all purposes. Especially for homes, solar power is the best alternative source of energy. If youre seriously considering installing solar panels on your roof, this article will tell you how to go about it.
Flat roofs are best suited for installing solar panels. The flat roof gives the flexibility to put in adjustable panels, which can be pointed at the sun directly. The surface area of a flat roof is bigger than slant roofs making it more ideal for installing panels.
Installation Instructions
1. Perform a due-diligence on the roof before proceeding with the solar panel installtion. This is to ensure there are no potential moisture problems or existing cracks or leaks on the roof. Also inspect the roof for sags or other abnormalities like depression on the roof. It is best to fix the roof if you detect any problems before starting the installation.
2. The installation works best if it faces south. In an east-west installation, the amount of electricity generated will be considerably lower. Before marking a place even in a south facing installation, make sure there are no objects that may cast a shadow. Solar panels work best when they are in a spot, which has constant exposure to the sun throughout the year.
3. Once you have earmarked the area for installation, start with installing the base of the solar panel racks. Bolt them to the roof using lag bolts. Depending on the strength of your roof, you can drill holes and then bolt the base. After installing the base, be sure to waterproof it by applying seal around it.
4. Attach the racks to the base that was bolted in the previous step. These racks are adjustable in a way that the panels are flat during summer and during winter are tilted to an angle perfect for receiving maximum sunlight.
5. The next step is to mount the solar panels in place. PV installations look perfect when they are installed parallel to the roof and the ground. Ensure that the panels are installed based on the circuit diagram provided. Sometimes you might require a combination of both series and parallel technique.
6. Lastly, connect each of the wires to the next that are located behind the panels and then connect the wire from the panel to the inverter. Panels are provided with wires behind them. Ensure that each of the wires is connected to the next correctly. To complete wiring of the system and connect the wires from the panels to the inverter installed in your home.
Also, connect the system to the buildings main electrical panel and the utility meter as the last step. All you need to do now is power up the system and it will start generating green electricity.
