The direction of your roof is a crucial factor in determining the efficiency of solar panels in Illinois.
South-Facing Panels: The optimal direction for solar panels in the United States, including Illinois, is south-facing. This orientation aligns with the sun's path, maximizing sunlight exposure and energy generation. South-facing panels are highly efficient in covering power usage and benefiting from net metering.
Alternatives to South-Facing Panels: Even if your roof isn’t ideally laid out, solar installations can still be effective. East-west systems can produce substantial power. Panels mounted at flat or steep angles can also be productive. However, the direction is more important than the angle, with most roof tilts working effectively.
Efficiency Loss for Non-South Orientations: Panels facing west or east produce about 15% less electricity compared to south-facing panels. For those with Time-of-Use (TOU) pricing plans, west-facing panels can be beneficial during peak electricity usage hours in the evening. North-facing panels are the least ideal, generating approximately 30% less power.
How Your Utility Fits into the Mix
Understanding how your utility company's policies interact with solar energy systems is vital.
Net Metering: Many Illinois utilities offer net metering, allowing homeowners to earn credits for excess energy supplied back to the grid. This can offset your monthly electricity bills.
Utility Rate Structures: Familiarize yourself with the utility's rate structures as they can impact how solar energy affects your electricity bills.
Deciding on the Type of Solar Installation
Choosing between a roof-mounted system and a ground-mounted system involves several considerations.
Roof-Mounted Systems:
Pros: They are space-efficient and generally have lower installation costs.
Cons: Limited by roof size and shape; may require roof modifications.
Ground-Mounted Systems:
Pros: Can be optimally positioned for sun exposure; easier maintenance.
Cons: Require more land, potentially higher installation costs, and may be more visible.
In summary, when installing solar panels in Illinois, it's important to consider the direction and angle of your roof, the policies of your utility company, and the type of solar installation that best suits your property. South-facing roofs are ideal for solar panel installations, but east-west orientations can also be effective.
Understanding these factors will help maximize the efficiency and benefits of your solar energy system.
