Solar Panel Installation - Everything You Need to Know
Installing solar panels on a roof can take one to three days, depending on the size of the system and the number of panels. The process may be further complicated if you're adding battery backup. After you've completed the installation, you'll need to get the final approval from your local building inspector. Once that's done, you're ready to begin enjoying the energy-free benefits of your new solar panel system. But before you get started, see this link to learn more about the basic of solar panel installation.
First, you'll need to connect the panels to the backfeed breaker and the microinverter. These devices control the voltage of each panel. There are positive and negative wires for each module. You'll need to attach a copper wire across the rails as grounding. This will help dissipate any anomalies caused by faults or lightning. Make sure that you use the right wires for your solar system.
Once you have the permits in place, the solar installation crew will set up the panels on your roof. They'll place electrical wiring and construct a racking system for the solar panels. Once the racking system is installed, the installers will attach the solar panels and connect them to the inverter. The final step is testing the system so you can see the results. Getting the permits is the first step toward a new solar system.
Once the system is installed, your local utility will inspect it to make sure it's compliant with local laws and codes. The inspector will double-check the installer's work and compare it to a checklist of compliance requirements. The inspector will inspect all parts of the system, including the wiring and the equipment. If the system meets the local codes, the installer will receive a letter certifying that the installation has been properly done. This letter is known as a Permission to Operate.
In order to connect your new solar system to the grid, your utility company will need to approve it. During the installation process, the utility representative will inspect the panels and the inverter to see that they are properly installed. The utility may also upgrade your meter for Net-Metering. This fee will cost a few hundred dollars, but it's built into a turnkey installation contract. You can check the performance of your new solar system by watching a short video on the EnergySage website.
A potential solar installer will determine how many panels are needed for your home. In addition to asking you how much electricity you use per year, they will also determine whether your property is suitable for solar panels. They will also measure the amount of sunlight reaching your roof. You can use a website like the National Renewable Energy Laboratory's PVWatts calculator to estimate how much sunlight your roof receives each day. The calculator will also help you choose the best size of batteries for your new solar system.

Once your roof is prepared, the next step is to install the mounting rails. These are mounted on the roof rafters. Remember to align the mounting holes on the solar panels to the mounting rails. The spacing between the mounting holes is noted in the panel spec sheet. After installing the solar panels, you'll need to attach flashings to the bottom and top rails of your roof. Alternately space the flashings so that the weight of the array is evenly distributed across all rafters.
