A solar photovoltaic (PV) system converts sunlight into electricity using solar panels. When sunlight hits the solar panels, the photovoltaic cells produce direct current (DC) electricity. This is then converted into alternating current (AC) by an inverter, making it suitable for use in homes, businesses, or export to the grid.
Modern solar systems may include batteries to store excess energy and smart monitoring tools to track performance. Solar PV systems are a clean, renewable energy source that reduces reliance on fossil fuels and helps lower electricity bills.
A standard solar PV system includes the following components:
Each component plays a critical role in ensuring efficient and safe solar energy generation.
The electricity a solar system can generate depends on several factors:
A 6.6 kW solar system typically produces around 24–28 kWh per day, enough to offset a significant portion of an average household’s electricity use. Commercial systems scale even higher, generating hundreds of kWh per day depending on size and setup.
The right system size depends on:
For residential homes, common system sizes range from 5 kW to 10 kW. For small businesses, it may range from 15 kW to 100 kW or more. Polygon Energy can conduct a tailored site assessment and provide a custom recommendation.
Yes, it’s possible to go completely off-grid, but it requires more than just solar panels. You’ll need:
Going off-grid provides complete energy independence but is more expensive and complex than grid-connected systems. It is most suitable for remote or rural properties.
If you have a grid-connected solar system without a battery, it will automatically shut down during a blackout to prevent backfeeding electricity, which is a safety risk for line workers.
However, if your system includes battery storage with backup functionality, it can continue powering essential circuits (lights, fridge, internet, etc.) during outages. Polygon Energy offers blackout-ready hybrid solar battery systems for uninterrupted power.
Yes, but it depends on the level and pattern of shading and the structure of your roof:
Polygon Energy uses advanced shading analysis tools to determine your site’s viability and offer the most efficient solution.
