San Diego Solar Contractors
Your utility bill probably hasn't dropped in years, and it's not going to start on its own. Viking Cooling & Heating designs and installs solar panel systems for San Diego homes, sized around how your household actually uses power. Solar panels capture sunlight through photovoltaic cells and convert it into direct current power, and your inverter turns that into the alternating current your home runs on, powering your lights, appliances, and everything else.
San Diego's abundant sunshine makes it one of the better places in the country to go solar, and as a veteran-owned local company, we'll give you the real numbers on whether it makes sense for your property. No pressure, no inflated promises, just an honest look at what solar could do for you.

Adding a battery to your solar system means you can use the power you generated earlier in the day even after the sun goes down, or during an outage. That's a real difference-maker when the grid goes out, and it makes your whole system far less dependent on perfect conditions. Picking the right battery comes down to your household's energy habits, which is something we work out together. We install batteries from established manufacturers, whether you're adding one to a system you already have or building it in from the start. Battery installs qualify for the same federal tax credit as your panels.
Solar Inverters
Your inverter takes the direct current power coming off your panels and turns it into the alternating current your home runs on. It also works nonstop whenever the sun's up, which makes it the component most likely to need attention down the road. Inverter pricing typically runs from $100 to $2,000 depending on your system's size. We match the inverter to your system's output during installation, and if yours starts acting up, we'll diagnose it and get it fixed.

What to Expect During Your Solar Installation
From Site Survey to Completion
- Site Survey: We come out, look at your roof or property, and figure out the right system size and placement.
- System Sizing: Most residential setups need somewhere between 120 and 600 square feet of panel space, depending on energy use.

- Installation: Our licensed team handles the install start to finish with equipment built to last.
- Completion: Most installs wrap up in one to three days depending on system size.
Solar Panel Repair
Even a solid system runs into trouble sometimes, whether that's storm damage, a fallen branch, or age catching up with it. When something's off, we inspect the system, find the actual cause, and fix it right the first time. We handle:
- Cracked or shattered panels
- Arc faults and electrical shorts
- Inverter malfunctions
- Hardware failures
- Low or inconsistent energy output
- Code violation corrections
Solar Maintenance and Cleaning
Solar panels don't need much upkeep, but they're not entirely maintenance-free. Dirt and debris build up over time, especially along the lower edge of the frame where rain doesn't reach, and that buildup eats into your system's output. Left alone long enough, dirty panels can lose up to 30% of their efficiency. We recommend at least one maintenance visit a year. We clean panels using methods that won't damage them, check the inverter, and catch small problems before they turn into bigger ones. Signs you need a maintenance visit or repair:
- A sudden drop in energy output
- Visible damage to a panel
- A roof leak near your panels
- A circuit breaker that keeps tripping
- A panel that feels hot to the touch
- An inverter that's underperforming or acting unpredictable

Frequently Asked Questions
Most come with a 25 to 30-year warranty, and with regular maintenance they'll often keep producing power well beyond that. Solar is a long-term investment, and quality panels installed correctly hold up for decades. We'll help you understand what to expect from the system we design for your home.
Not much. Mostly periodic cleaning to clear off dirt and debris so the system keeps running at full output. In San Diego's dry, dusty stretches, buildup happens faster than you'd think, which is why we recommend at least one visit a year to keep production up.
Many of the systems we install qualify for federal and state incentives, which can significantly reduce your upfront cost. We'll go over what applies to your specific situation so you have a clear picture of the real investment before you decide anything.
There's an investment upfront, but most homeowners save hundreds of dollars a year on energy costs, and available credits help offset the initial price. Given San Diego's sunshine and rising utility rates, the math works out well for a lot of homes. We'll run the honest numbers for yours.
Yes, just at reduced output compared to full sun. San Diego gets plenty of sunny days, so overcast stretches don't hold most systems back much. If you've added a battery, you can also draw on stored power when conditions aren't ideal.
Most residential rooftop installs take one to three days, depending on how many panels you're putting in. We'll give you a clear timeline during the walkthrough so you know exactly what to expect before we start.
It does. The federal credit applies whether you're adding a battery to an existing system or installing both together. We'll help you understand how the incentives work for your setup so you can make the most of them.
We do. Before any solar installation, we'll survey your property, walk through your options, and give you a free estimate with clear, upfront pricing. There's no obligation, and our Best Price Guarantee means fair pricing from a local, veteran-owned team.
