Let's Talk Through the Basics
A Well Designed Grid-Tie System Can Save You Money
Generating your own solar power in the Okanagan is now more affordable than ever. With the recent drop in solar PV prices, you could see a return on your investment in as little as 8 years, depending on factors like system size, southern exposure, and utility price increases.
Most residential solar power systems are installed flush against the roof, which requires good southern exposure and enough space. Each kilowatt of solar power needs about 100 square feet of roof space.
A solar electric system can last up to 30 years with minimal maintenance. It can also increase your home’s value if you decide to sell. Today’s systems are about 95% efficient, meaning almost all the power generated is used in your home, with any excess going to the grid.
Grid-Tie Components and Functionality
Delve into the components that make up a grid-tie system and how each contributes to harnessing solar energy efficiently while remaining connected to the grid. Understand the role of inverters, meters, and other key elements in maximizing energy production and savings.
Solar Panels
Solar panels are the core of a grid-tie solar system, capturing sunlight and converting it into direct current (DC) electricity. Comprising photovoltaic cells, these panels harness solar energy to produce clean, renewable power for your home or business.
Electrical Appliances
Electrical appliances in your home, such as refrigerators, lights, and computers, use AC electricity to operate. In a residential grid-tie solar power system, the AC power generated by the solar panels, after being converted by the inverter, directly powers these appliances. Any excess solar power not used immediately can be fed back into the utility grid, potentially earning you credits or reducing your energy bill.
Utility Grid + Meter
In a grid-tie solar system, your panels connect to the utility grid, allowing you to use solar power when available and draw electricity from the grid when needed. A bi-directional meter measures the energy your system produces and tracks what you send back to the grid, ensuring you’re billed only for the net electricity you consume.
Grid-Tie Micro Inverter
A microinverter, installed directly on each solar panel, regulates the voltage and current to ensure optimal energy conversion at the panel level. It converts the direct current (DC) generated by the panel into alternating current (AC) immediately, which powers your home’s electrical appliances. Any excess power is fed directly into the electrical grid, ensuring efficient and safe integration with the utility system.
