Additionally, solar incentives, tax credits, or rebates offered by states and local governments have to be well-researched to reduce the overall cost of your solar installation.
Solar Panel Installation Process
Installing solar panels involves a few extremely influential steps that must be carefully planned for a successful and efficient setup. Here is a detailed analysis of the solar panel installation process explained in a step-by-step process:
1. Assessment of Roof, Energy Consumption, and Necessary Permits:-
You must determine whether the roof is suitable without having any shading issues (it is a plus point if it is a south-facing roof). Also, you should evaluate your current energy consumption patterns so that you can size the solar system on your roof accordingly. Moreover, the installation of your roof must be compliant with local regulations, and have obtained the necessary permits.
2. System Design:-
Generally, the installer will design the system based on your energy needs, which involves selecting the type and number of solar panels along with the inverter and other required components for the system.
3. Approval from Local Authorities:-
Before you proceed with the installation, you must ensure that everything related to your solar system complies with local regulations. And, you need to obtain the necessary approval from your local authorities that acts as a license for your solar installation.
4. Mounting the Hardware on your Roof:-
For a proper installation, the necessary hardware modules have to be mounted on the roof such that they hold the panels perfectly. Moreover, the mounting has to align securely with the roof structure.
5. Installation of Solar Panel, Inverter, and Electrical Wiring:-
Panels are placed onto the mounting and must be oriented perfectly such that more sunlight can be captured to improve the energy production. The inverter is connected to convert DC electricity to AC and all necessary electrical wiring is done. And, if your system is Grid-Tied, then your installer will connect it to the grid.
Monitoring and Maintenance
Regular monitoring of solar panels is very influential to ensure operating at a peak level of efficiency. By this, you can identify any possible issues early and also optimize your energy production for a longer lifespan of the system. Moreover, monitoring will alert you about shading issues and help you schedule your maintenance, which further reduces the repair costs.
Tools and Technologies used for monitoring solar panel performance:
- Solar Monitoring Systems
These systems will help you provide all necessary real-time data about each panel’s production and performance. Also, there are a few popular apps that you can consider for monitoring your solar system such as Enphase Enlighten, SunPower Monitoring, mySolarEdge, and Tesla app.
- Mobile Apps, Web Portals, and Energy Monitors
You can have real-time insights about consumption using specialized user-friendly apps, and it can be accessed from anywhere.
