- Does your roof have unobstructed, clear access to sunlight for most of every day?
- Is there ample roof space or an area large enough to mount the system?
- Is the investment worth it?
- Can you meet requirements for local permits?
Selecting the Right System
Evaluate your energy consumption patterns before selecting your solar system components, so you can choose the appropriate photovocaic (PV) system size for your home, and help reduce your overall electrical use. Begin by performing a load analysis, which should include:
• Recognizing your current consumption trends
• Examining your utility bills for the past year
• Calculating your energy consumption
A Grid-Connected or Stand-Alone System?
A grid-connected PV system uses power from your utility’s grid when it does not produce enough energy. When your system produces excess electricity, your utility provider is required to buy it. With net metering, your provider pays retail price for excess power that you send back through the grid.
• You live in a remote location and it would be more cost-effective.
• You are planning to install a hybrid electric system that also uses a small wind electric system.
• You have minimal power needs.
