Why Go Solar in San Diego?
Living in San Diego means abundant sunshine – a perfect resource for generating clean, affordable electricity. Here’s why more local homeowners are making the switch:
- Lower or Eliminate Rising SDG&E Bills: Take control of your energy costs and reduce reliance on expensive utility power.

- Maximize Your Investment: San Diego’s high electricity rates mean solar savings can be substantial, offering an excellent return on investment.
- Increase Your Home Value: Homes with solar systems are increasingly attractive to buyers and often sell faster.
- Reduce Your Environmental Impact: Power your home with clean, renewable energy and lower your carbon footprint.
Understanding Your San Diego Solar Energy System
A solar energy system is a sophisticated setup designed to capture sunlight and convert it into usable electricity for your home. While the technology is advanced, the core concept is straightforward:
- Solar Panels: Mounted on your roof or ground, these panels capture sunlight using photovoltaic (PV) cells.
- Inverter: This crucial component converts the direct current (DC) electricity produced by the panels into alternating current (AC) electricity, which is what your home appliances use.
- Mounting & Racking: Securely attach the panels to your roof, protecting them from wind and weather.
- Monitoring System: Allows you to track your system’s performance, electricity production, and consumption in real-time.
- Battery Storage (Highly Recommended): Store excess solar energy generated during the day to use at night or during outages, maximizing self-consumption and savings, especially under Net Energy Metering 3.0 (NEM 3.0).
The Critical Role of Battery Storage in San Diego (NEM 3.0 Explained)
California’s recent shift to NEM 3.0 significantly changed how solar credits work. Under NEM 3.0, the value of exporting excess solar energy back to the grid (especially during the middle of the day when solar production is highest) has been reduced compared to previous policies.
This is why battery storage is now essential for San Diego homeowners with solar:
- Maximize Self-Consumption: Store solar energy generated during the day instead of sending it to the grid for lower credit. Use this stored energy in the evening when electricity rates (Time-of-Use rates) are highest.
- Increase Savings: By using your own stored solar energy during peak expensive hours, you drastically reduce the amount of electricity you need to buy from SDG&E at high rates.
- Backup Power: A battery provides critical backup power to keep your lights, refrigerator, and other essential circuits running during grid outages.
We specialize in designing and installing integrated solar-plus-battery storage systems that are optimized for San Diego’s energy rates and conditions under NEM 3.0, ensuring you get the most value and energy security from your investment.

Frequently Asked Questions About Solar in San Diego
Is solar worth it in San Diego with NEM 3.0?
Yes, absolutely. While NEM 3.0 changed export credits, pairing your solar system with battery storage is now even more critical and makes solar highly valuable. Batteries allow you to store energy and use it during expensive peak hours, maximizing self-consumption and savings and providing essential backup power during outages.
How much does a solar energy system cost in San Diego?
The cost varies depending on your home’s energy needs, the system size, and whether you include battery storage. However, significant savings on your electricity bills, combined with federal tax credits and potential state incentives (like SGIP for batteries), make solar a strong investment with a relatively fast payback period compared to high SDG&E rates. We provide detailed, personalized quotes.
How long does the solar installation process take?
The physical installation on your home typically takes 1-3 days. The overall process, including site assessment, design, permitting, and utility interconnection with SDG&E, can range from a few weeks to a few months, depending on local permitting timelines. We work efficiently to get your system operational as quickly as possible.
Do I still receive an electric bill with solar?
In most cases, yes. You’ll likely still have minimum charges from SDG&E. However, a properly sized solar-plus-battery system can dramatically reduce the amount of electricity you need to purchase from the grid, significantly lowering your overall bill.
What kind of maintenance do solar panels require?
Solar panels require very little maintenance. We recommend occasional cleaning, especially after Santa Ana winds or long dry spells, to remove dust and debris that can impact efficiency. We can advise on cleaning or include it in a West Coast Club maintenance plan if offered. Regular monitoring helps detect performance issues.
What size solar system do I need?
The optimal system size is determined by your average electricity consumption (based on your past utility bills), your roof space and orientation, and whether you plan to include battery storage. We perform a detailed analysis during your consultation to recommend the perfect size for your home.
