Solar panels are one of the most efficient ways to generate clean, renewable power for your home. They reduce your dependence on utility companies, lower electricity costs, and provide a reliable energy source year after year. But how does the technology actually work? Here’s a clear look at how solar energy powers homes in Calgary.
How Solar Energy Works in a Home
When sunlight hits your solar panels, the panels convert that light into direct current (DC) electricity. An inverter then changes the DC electricity into alternating current (AC), which powers your home’s outlets, lighting, and appliances. Any unused energy is either stored in a solar battery or sent back to the grid for credit through Alberta’s net metering system.
- Solar panels convert sunlight into direct current (DC) power.
- The inverter changes DC power into alternating current (AC).
- Your home uses that power for all electrical needs.
- Extra energy is stored in a battery or sent to the grid for credit.
Understanding Net Energy Metering in Alberta
Net Energy Metering (NEM) allows Calgary homeowners to send extra power to the grid and draw it back later when needed. During the day, your system produces more electricity than your home uses. At night or on cloudy days, you can pull that same amount back from the grid, keeping your energy use balanced over time.
If your solar system produces more power than you use over a month, you earn energy credits that can roll forward to future bills. At the end of each year, your utility company “true-ups” your account to calculate your total usage and credits. If you’ve used more electricity than you produced, you pay the difference. If you’ve generated more, you’ll receive credit at a set rate.
Main Components of a Residential Solar System
Solar Panels
Solar panels are made of multiple photovoltaic cells that convert sunlight into electricity. They are usually installed on rooftops but can also be ground-mounted for homes with open space. The more efficient the panels, the more power your system generates.
Inverter
The inverter converts the DC electricity from your panels into AC power for your home. Most systems use either string inverters or microinverters. String inverters handle power from multiple panels together, while microinverters are installed behind each panel for more independent and efficient performance.
Monitoring System
A solar monitoring system allows you to track real-time energy production and usage. You can view this data through a mobile app or online dashboard. Monitoring helps ensure your system is working properly and allows you to understand your home’s power patterns.
Racking System
The racking system secures your solar panels to the roof or ground. For roof installations, proper flashing and sealing are essential to prevent leaks and protect the structure from weather exposure. The type of racking depends on your roof’s design and material.
Starting a Solar Project in Calgary
Before installation, it’s important to choose a qualified solar company with a proven track record. Look for a contractor who provides detailed design plans, strong workmanship warranties, and clear communication throughout the process. You should also review your contract carefully for key details such as payment schedule, service upgrades, equipment specifications, and production estimates.
Installation and Maintenance
Most residential solar systems in Calgary can be installed in one or two days. The process involves attaching mounting brackets, securing panels, running wiring through conduit, and connecting the inverter to your main electrical panel. Once complete, the system is inspected and activated.
Maintenance is minimal. Solar panels should be kept clean of heavy dust or debris, though Calgary’s weather often does most of the cleaning naturally. Snow will typically melt or slide off on its own. If your system ever requires service, your workmanship warranty covers repairs or replacement of faulty components.
