Local Factors
Getting solar installed in San Marcos involves navigating San Diego County’s permitting process. It’s generally straightforward, but expect some paperwork and inspections. A qualified solar installer will handle most of this for you. Installation labor rates in the San Diego area are competitive, but be sure to get multiple quotes. Also, remember to verify contractor license at California Contractors State License Board (CSLB) before you hire anyone!
Keep in mind California’s solar landscape has changed with NEM 3.0 (Net Energy Metering). Under this new billing tariff, excess solar energy sent back to the grid receives lower compensation. Therefore, consider adding a battery system, like a Tesla Powerwall, to store excess energy and maximize your savings. This allows you to use your solar power when you need it most, reducing your reliance on the grid, especially during peak hours.
Additionally, remember that thanks to California law, adding solar panels will *not* increase your property taxes. Plus, thanks to the 30% Federal Tax Credit (ITC), you can deduct 30% of the total system cost from your federal taxes in 2026. Many homeowners in California see a full return on their investment within 7 to 9 years.
Finally, be aware that most new homes built in California are *required* to have solar systems installed, thanks to Title 24 regulations.
