How to compare solar quotes in Atherton, CA?
Direct Answer
When comparing solar quotes in Atherton, always look at the Price Per Watt (PPW), the exact equipment brands (e.g. Enphase vs Tesla), and the contractor's labor warranty duration.
Detailed Explanation
For residential installations in Atherton, a competitive PPW typically ranges from $2.70 and $3.20. Quotes that fall far below this range often indicate the use of older, less efficient technology or substandard installation practices. Aside from cost, pay close attention to the hardware specified in each proposal. The inverter technology is particularly important. Systems utilizing microinverters (such as those manufactured by Enphase) or DC optimizers (like SolarEdge) generally outperform traditional string inverters, especially if your roof in Atherton experiences partial shading from trees or nearby structures.
Finally, review the warranties provided by each solar company. While the solar panels themselves usually carry a standard 25-year manufacturer's performance warranty, you must also check the duration of the contractor's workmanship and roof penetration warranty. A reliable installer in Atherton will back their labor with a minimum 10-year guarantee, insulating you against potential roof leaks or faulty wiring long after the installation is complete.
Key Takeaways for Atherton Homeowners:
- PPW: Should be under $3.00/W.
- Inverter Type: Microinverters are generally preferred over string.
- Labor Warranty: Look for at least 10 years.
