- Use past bills 6–12 months to see total power units and seasonal differences.
- Evaluate daytime load from startup time, Smart Meter work schedule or Load Profile.
- Systems that are too large for daytime loads may overproduce power and slow payback.
- A system that is too small may not reduce energy costs to their full potential.
The condition of the roof must support the weight and lifespan of the system.
Solar panels are heavy and must be attached to the roof structure for a long time. Therefore, you must always check before installing.
