A solar panel system converts sunlight into electricity using photovoltaic (PV) panels. When sunlight hits the panels, the photovoltaic cells within them generate a flow of direct current (DC) electricity. This DC electricity is then converted into alternating current (AC) electricity by an inverter and sent to the home's electrical panel for use. Excess electricity can be fed back into the grid, and when needed, electricity can be drawn from the grid. This integration of solar power allows homeowners to generate clean energy, reduce their electricity bills, and contribute to a sustainable future.
When considering getting a solar panel system, there are some key things to consider:
What are my energy needs? (What is my average monthly hydro bill and how much of that energy would I like to offset? Do I want my whole house to have power or just some key appliances?)
Do I want to rely on the grid for some power or do I want to have battery backup for when the sun isn't shining or the grid power is down?
Do I want a backup generator added to my system for long-lasting emergency power?
We start by virtually mapping out your roof in our solar design program. This will give us an idea of the size and type of solar panel system we can use on your individual roof. We listen to your specific needs and adjust anything from there. If you need any service upgrades for the system, our electricians would perform those beforehand. If you are interested in receiving the Greener Homes Grant/Loan, you must have an energy assessment done before any retrofits have begun. From there, we install your solar panel system and you start seeing savings on your next BC Hydro bill.
Whether it be combined with your solar panel system, back up battery system or just on its own, we supply and install Generac generators so your family isn't caught in the dark during outages.
Even with a backup battery added to your solar panel system, depending on the size and number of batteries, you may not have enough backup energy to power your home for longer outages. That's where a backup generator comes in. Once your solar battery runs out, you can still have reliable power in emergencies!
Solar Panels (Photovoltaic Modules): These are the key components that convert sunlight into electricity. They are usually made up of multiple interconnected solar cells and are mounted on the roof or ground.
Mounting System: The mounting system provides structural support for the solar panels and ensures they are securely installed on the roof or ground. It includes racks, rails, and clamps. Different types of mounting systems are used for different roof types and roof slopes.
Inverter: The inverter is responsible for converting the direct current (DC) electricity generated by the solar panels into alternating current (AC) electricity, which is used in homes. It also ensures the system operates at its maximum efficiency.
Microinverters and DC Optimizers (Optional): Microinverters and DC optimizers are advanced technologies used in solar panel systems to maximize performance. Microinverters convert the DC electricity generated by each panel into AC electricity individually, ensuring optimal output even in shaded or dirty conditions. DC optimizers regulate the DC output at the panel level, allowing for monitoring and maximizing energy harvest.
Solar Batteries (Optional): If you want to store excess solar energy for later use, you can include solar batteries in your system. These batteries store the excess electricity produced during the day for use during the night or in case of a power outage. We also have optional propane or natural gas standby generators that can kick in after your solar battery has run out (e.g. if power has been down for more than a few hours or you have an off-grid system)
Charge Controller (Optional): In systems with solar batteries, a charge controller is used to regulate the charging and discharging of the batteries, preventing overcharging or deep discharging.
Electrical Panel: The electrical panel, also known as the main breaker panel or distribution panel, is the central hub that distributes electricity throughout your home. The solar system is connected to the electrical panel to supply electricity to your household appliances.
Monitoring System: A monitoring system allows you to track the performance of your solar panel system in real-time. It provides data on energy production, consumption, and system efficiency, helping you optimize your energy usage. Most solar panel systems will have some sort of monitoring capabilities.
Wiring and Cables: These components connect the solar panels, inverter, batteries (if applicable), and electrical panel. High-quality wiring and cables are crucial for efficient and safe energy transfer.
Electrical Disconnects (Rapid Shutdown System): These devices are installed to ensure the solar panel system can be safely disconnected from the grid or electrical supply during maintenance or emergencies.
Bidirectional Meter: For any grid-connected system, you require a bidirectional meter to measure the energy generated by your solar panels and the energy exported back to the grid as well as the energy being consumed by the grid.
Grounding Equipment: Proper grounding of the solar panel system is essential for safety. Grounding equipment includes ground wires, ground rods, and grounding lugs, which help dissipate any potential electrical faults.
Surge Protection Devices: Surge protectors safeguard your solar panel system from power surges caused by lightning strikes or other electrical disturbances, preventing damage to the system's components.
Remember, the specific components required for your solar panel system may vary based on factors such as system size, location, local regulations, and individual preferences.
