Homeowners, private companies, and even government institutions are turning to solar panel energy supply. Why? Because it is a way to reduce utility bills and minimize carbon footprint. You may be wondering how these solar panels work.
They are devices that convert sunlight into electricity through the photovoltaic (PV) effect. Solar panels are composed of multiple solar cells and each cell absorbs photons (light particles) from the sun. From the solar cells, photons knock electrons loose from their atoms, creating a flow of electricity. The electricity produced is in the form of direct current (DC), and an inverter is used to convert it to alternating current (AC). This generated AC power can now be used to power appliances and lights, stored in a battery, or even sent back to the grid.
If you’re new to the world of solar panels, don’t worry. The solar panels installation in Melbourne is actually quite manageable with the right preparation. So, here’s a beginner-friendly guide to orient you on what you need to know about solar panel use.
Understand Solar Panel Basics
Solar panels have a great impact on managing your electric bill. But, first of all, you must be aware of what are these panels for, what materials they are made of, how they work, and what factors should be considered for their installation. You need to be aware of these key terms: photovoltaic cells, inverter, and battery storage.
Assessing Your Home for Solar Panel
Not all homes are compatible with solar panel installation. You should consider how durable is the roof that will accommodate the panels. So, it is best to repair or replace it first before installing a solar panel of 25-30 years lifespan. The more sunlight your place receives and minimal shading, the better. Roofs that face south, southeast, or southwest in the Northern Hemisphere are the best.
Calculating Your Energy Needs
Check your electrical consumption measured in kilowatt-hours (kWh) found in your utility bill. From here, your average monthly usage will help you determine the size of your solar equipment.
Choosing Your Solar Panel Type
Monocrystalline panels are the most efficient and durable but more expensive. Meanwhile, polycrystalline is less efficient but more affordable. And the thin-film panels are lightweight but have less effective performance. However, thin-film is best for unconventional shapes or limited-space roofs.
Picking an Inverter
Connecting all the panels in a series is the feature of string inverters wherein if one panel is shaded, the entire system’s efficiency drops. So, this is a solution for areas with minimal shading. However, microinverters installed on each panel allow each panel to work independently making it useful if the roof has shaded parts.
Hiring a Professional Installer
A licensed installer can work on the permits and make sure everything complies with building codes. They also offer warranties that cover their work and the equipment. And of course, they are trained to manage whatever risks or problems that may be encountered before, during, and after the installation.
Navigating the Costs and Incentives
Learn about the incentives that can offset the cost like federal tax credits, state and local incentives, and net metering.
Maintenance of the Equipment
Occasional cleaning is needed, but more frequently if you live in snowy or dusty areas. At the same time, inspection especially by a professional will ensure that it’s working optimally. You, yourself can actually track its performance with apps or online dashboards.
By being aware of these considerations, you’re on your way to a rewarding investment, not only for your pockets but also for the environment.
