Other Factors That Affect Solar Panel Costs
- Type of Panels: Monocrystalline panels are more efficient (but, yes expensive) than polycrystalline ones.
- Roof Type & Pitch: Steep or complex roofs increase labor work and time, hence increasing the solar installation cost.
- Battery Storage: Adds independence but increases upfront cost by 25–50%.
- Permitting & Utility Fees: Vary by city and can add $500–$2,000.
Benefits of Adding Solar Batteries
Batteries are for storing excess energy your system produces and you can use it during power outage and dark hours. Choosing the more efficient battery, like the Tesla Powerwall, is essential to benefit from the maximum efficiency of the system. It is an ideal option in the areas where load shedding is high since it offers maximum savings with net metering.
The Average Cost of Solar Batteries
| Single Battery | Battery for Large System |
| $9,000–$13,000 | $15,000–$20,000 |
What Type of Solar Panels are Best in 2025?
| Type | Efficiency | Lifespan | Cost per Watt | Best For |
| Monocrystalline | 20–23% | 25–30 years | $1.00–$1.50 | Small roofs, high output |
| Polycrystalline | 16–18% | 20–25 years | $0.80–$1.00 | Budget-friendly homes |
| Thin-film | 10–13% | 10–20 years | $0.50–$0.80 | Commercial or flat roofs |
The Best Option: Modern monocrystalline panels (like REC Alpha or QCells) dominate U.S. residential markets thanks to their superior output and warranties.
What Expenses Must be Included in a Solar Installation Quote?
When you compare the quotes from multiple solar installation companies, look for the following points to go with the best one (affordable rates and covering maximum points).
| Component | Description | % of Total Cost |
| Solar panels | The actual photovoltaic modules | 25–30% |
| Inverter | Converts DC to AC power | 10–15% |
| Mounting hardware | Rails, brackets, bolts | 5–10% |
