Whether you’re a first-time solar buyer or replacing an aging system, Solion Energy makes residential solar installation in San Diego straightforward – from permit to PTO, we handle everything. No commissioned sales reps pushing you toward oversized systems. No subcontractors you’ve never met showing up at your door. Just a licensed San Diego solar team with a simple approach: right-size the system, install it properly, and stand behind the work.
Going solar doesn’t have to be complicated. Most of the friction homeowners experience with solar installs comes from working with large companies where your job is handed off between departments, sales reps, and subcontractors. Our process is direct and transparent from the first call to the day your system powers on.
Here’s how a typical Solion residential installation works:
Step 1: Free Site Assessment & Quote
We start with a site visit and a review of your SDG&E utility bills. We look at your roof’s age, condition, orientation, and shading, then design a system that matches your actual energy consumption — not the largest system we can sell you. You receive an itemized proposal with system size, equipment specs, projected annual production, estimated savings, and all available incentives.
Step 2: Permit Filing
We handle all permitting with the City or County of San Diego. Most homeowners never have to interact with the permitting process at all — we file the documents, respond to any plan check comments, and schedule the required inspections.
Step 3: Installation Day
Most residential solar installations are completed in one to two days. Our team arrives on time, protects your property, and completes the install cleanly. We walk you through the system before we leave so you understand exactly what’s been installed and how to monitor it.
Step 4: Inspection & Utility Interconnection
After installation, the system is inspected by the local Authority Having Jurisdiction (AHJ). Once it passes, we submit your interconnection application to SDG&E and coordinate Permission to Operate (PTO). This process typically takes two to six weeks depending on SDG&E’s current queue.
Step 5: System Goes Live
Your system is energized, and you start generating your own electricity. We set up your monitoring portal so you can track production in real time, and we’re available if you have questions after the job is done.
Every Solion residential installation is designed for your specific home – not templated from a catalog. That said, most residential systems include the same core components.
Solar Panels
We install Qcell solar panels — high-efficiency monocrystalline panels with strong performance in San Diego’s combination of direct sun and coastal haze. Qcell panels carry a 25-year product and performance warranty and are the same equipment used by major national installers.
Microinverters / Inverters
We typically install Enphase microinverter systems for residential projects. Unlike string inverters, microinverters work at the individual panel level — so if one panel is shaded or underperforms, the rest of your system isn’t dragged down. Enphase also provides module-level monitoring so you can see exactly how each panel is producing.
Racking & Mounting Hardware
All panels are mounted with commercial-grade racking systems engineered for San Diego’s wind and seismic requirements. Roof penetrations are flashed and sealed correctly — a detail that matters a lot over a 25-year system life.
System Monitoring
Every installation includes a monitoring portal, accessible by phone or computer, where you can track your system’s real-time and historical production. You’ll know your system is working — and so will we.
Permits & Inspection
Permitting and inspection coordination are included in every installation. This is non-negotiable — unpermitted solar installations create title and insurance issues that affect your ability to sell your home.
Utility Interconnection & NEM Enrollment
We handle SDG&E interconnection paperwork and enroll your system in Net Energy Metering (NEM), which allows you to receive bill credits for excess electricity your system sends to the grid.
A solar-only system produces energy during the day and exports surplus power to the grid. That works well under SDG&E’s Net Energy Metering program, but there’s a limitation: when the grid goes down, a standard grid-tied solar system shuts off automatically for safety reasons — even in full sun.
Adding a battery changes that equation.
Why San Diego homeowners add battery storage:
Backup power during outages. San Diego experiences more wildfire-related PSPS (Public Safety Power Shutoff) events than most of the country. A battery keeps your critical loads running when the grid goes down.
Time-of-use rate management. SDG&E’s time-of-use rates mean electricity costs significantly more during evening peak hours (typically 4–9 PM). A battery lets you store solar energy generated during the day and use it at night instead of drawing from the grid at peak rates.
NEM 3.0 optimization. Under California’s current NEM 3.0 rules, the value of excess energy exported to the grid is lower than it used to be. Battery storage lets you consume more of what your panels produce, rather than exporting it at reduced credit rates.
If you’re unsure whether battery storage makes financial sense for your home, we’ll give you an honest answer – with numbers – as part of your quote.
Tesla Powerwall
Solion is a licensed Tesla Powerwall installer. The Powerwall is a 13.5 kWh AC-coupled battery that integrates cleanly with both new and existing solar systems. It can be set to prioritize backup power, self-consumption, or time-based control depending on your goals. Multiple Powerwalls can be stacked for greater capacity.
Enphase IQ Battery
For homes already running Enphase microinverters, the Enphase IQ Battery offers a tightly integrated storage option with module-level monitoring and flexible capacity configurations.
Solion Energy serves homeowners throughout San Diego County. From coastal neighborhoods to inland communities, our team brings the same licensed, local approach to every job.
Why local knowledge matters in San Diego solar:
San Diego’s solar landscape isn’t uniform. Coastal homes deal with marine layer and salt air. Inland areas see higher temperatures and more direct sun hours. Some neighborhoods fall under City of San Diego jurisdiction; others are in unincorporated County territory with different permitting requirements. Canyon-adjacent homes often have shading considerations that affect system design. Our team knows these variables because we’ve been installing here for years — not because we read a spec sheet.
Areas we regularly serve include:
Chula Vista · National City · El Cajon · La Mesa · Santee · Spring Valley · Lemon Grove · San Diego (all neighborhoods) · La Jolla · Pacific Beach · Mission Hills · North Park · University City · Mira Mesa · Scripps Ranch · Poway · Rancho Bernardo · Rancho Peñasquitos · Carmel Valley · Del Mar · Solana Beach · Encinitas · Carlsbad · Oceanside · Vista · San Marcos · Escondido · Ramona · Alpine · Lakeside

Most residential solar installations in San Diego range from $15,000 to $30,000 before incentives, depending on system size, equipment, and roof complexity. See our full Solar Cost & Pricing Guide for a detailed breakdown.
The physical installation typically takes one to two days. The full process – from signed agreement to Permission to Operate (PTO) – generally runs four to eight weeks, with most of that time spent on permitting and SDG&E’s interconnection queue, not on our end.
Not necessarily, but it’s worth evaluating. If your roof is more than 15 years old or shows signs of wear, we’ll flag it during the site assessment. Installing solar on a roof that needs replacement in the next few years means paying for panel removal and reinstallation later – which you can avoid by addressing the roof first. We work with roofing contractors across San Diego and can help coordinate if needed.
A standard grid-tied solar system will shut off automatically during a grid outage, even in full sun. This is a safety requirement to protect utility workers. To maintain power during an outage, you need a battery storage system such as a Tesla Powerwall. See our Tesla Powerwall page for details.
Most solar customers significantly reduce their SDG&E bill but don’t eliminate it entirely. You’ll likely still pay a small monthly customer charge, and your bill will vary by season based on production vs. consumption. Under Net Energy Metering (NEM 3.0), excess energy your system exports to the grid earns bill credits that can offset charges during months when your system underproduces.
The ideal San Diego roof for solar faces south, southwest, or west, has minimal shading from trees or neighboring structures, and is in good structural condition. Tile, composition shingle, and standing-seam metal roofs are all workable. We’ll give you an honest assessment during the site visit – if your roof isn’t a strong candidate, we’ll tell you.
