Quick Summary
Solar panels require a substantial upfront investment, depend entirely on sun exposure, cannot generate power at night, and require a roof in good condition that is not heavily shaded.
While the benefits of solar are massive, understanding the limits and constraints helps prevent sizing or financial expectations errors.
Key Constraints & Limits
- Rooftop Suitability: North-facing, weak, or heavily shaded roofs are not suitable for solar panels.
- Storage Requirements: To run appliances during power outages or night, you must add expensive battery banks.
- Roof Age: If your roof is over 15 years old, you should replace it *before* installing solar, as removing panels later costs $3,000+.
