California continued to lead the nation in solar capacity in 2025 and remains the leading source of new electricity generation, despite temporary manufacturing constraints and utility companies’ changes to their net metering policies.
Green energy and the cost-effectiveness of solar continue to be the top reasons people choose to install solar. San Luis Obispo’s Electricraft, Inc., has been serving the solar and electrical needs of local communities since 1984, including answering the many questions about solar installation.
The team has compiled the following FAQs to help answer questions about installing solar panels on a roof, the cost, and return on investment (ROI), battery storage, and more.
These FAQs answer the most commonly asked questions, but there’s nothing like a site visit and a conversation to get a complete picture of the benefits of solar. And, Electricraft offers free estimates, along with some substantial warranties.
Do I have to put solar panels on my roof?
Roof solar panel installation is the most common method in urban properties. Rural properties have more options for solar panel installation. Ground mount, or on the roof of a suitable other building on the property, are alternatives.
Making sure a roof is strong enough to hold the panels and equipment is necessary. Most modern roofs will be in good shape for solar panels, but it’s advisable to have a professional evaluation verifying the roof can handle the load. Reinforcement or an alternative mounting may be needed to avoid safety issues.
How long does installation take?
Once the permits and the utility connection are in place, the actual installation only takes a couple of days. The design, permit process, and inspections can take a few weeks, maybe longer, depending on your local government’s processes.
The San Luis Obispo solar installation team works closely with you from start to final inspection to make sure you are fully informed and that the entire process runs as smoothly as possible.
How much do solar panels cost?
Costs depend on your location, roof type, system size, and equipment. Residential systems average in the mid-five-figure range, and price is typically quoted based on per watt of capacity.
Incentives and rebates can offset the cost. Check with your accountant to confirm which incentives are available and in your best financial interest.
Electricraft can also assist with low-interest loans and financing programs, as well as free estimates.
How soon will I break even?
Breaking even, the time it takes for your energy bill to equal the net cost of the system, typically occurs between 7 and 12 years. The electric bill savings start immediately, which helps offset the cost of the system.
How much will I save with solar?
As part of the free estimate, Electricraft models your annual electrical usage, then shows you how much of your electrical usage will be offset by a solar system. The higher your utility rates and the more electricity you use during the day, the more you can save with solar.
Do I need battery storage?
Most residential solar systems are connected to the grid, making batteries optional. Batteries add backup power and reduce reliance on the grid at night, or during outages. Because they increase upfront costs, many decide to add batteries at a later time.
How long will a solar system last?
Solar panels rated for residential use can last 30 years or more. The inverter, which converts solar energy into electricity, may need replacement between 10 and 15 years. Solar panels have no moving parts and require very little maintenance beyond regular cleaning, which contributes to their longevity.
When you work with the San Luis Obispo solar installation team, you get:
- High-quality solar panels and components.

- Ten-year workmanship warranty.
- Local, turnkey design, permitting, installation, and maintenance by experienced and knowledgeable electricians and solar technicians.
- Licensed and certified service and maintenance.
- Detailed instructions for using your solar system.
How much energy do I need?
The installation team analyzes your energy use and recommends solar systems that are going to give you the best ROI. Optimal ROI includes data such as how much you can save on the electric bill, the cost of the system, your break-even timing, and other relevant technical information.
Can I charge my EV with solar?
Yes. You can charge EVs at home with solar energy. EV chargers run on electricity, which means they also operate on the electricity generated by a solar system. The real question is “How do I get the best EV charging performance from my solar system?”
- EVs come with a Level 1 charger to plug into a 120V outlet. Level 1 chargers can take a long time to charge. Consider upgrading to a Level 2 charger.
- For new solar systems, Electricraft includes EV charging in the estimate and design. If you want to upgrade an existing solar system to include EV charging, Electricraft can help.
- Other EV charging options include backup batteries so overnight charging isn’t pulling power off the grid, or a stand-alone off-grid EV charging station.
Will a solar system improve property values?
Various real estate reports state that a well-maintained solar system can increase property values by an average 6.9%. Homes in high-demand regions, like California, can see values increase by as much as 10%. The newer the solar system, the higher the percentage.
Do I need HOA approval?
California HOAs cannot ban solar panels, but do need to review and approve the plans. They have 45 days to approve code-compliant plans.
Many HOAs have financial maintenance and replacement obligations for commonly shared properties, such as a roof on a multiple-unit building, or a common-shared open area. However, as long as the roof is in good condition, this might be a reason to deny or delay a solar installation project.
The best thing to do is review the HOA guidelines and make sure your plans are compliant. They cannot lawfully stop your project for arbitrary aesthetic reasons, but they may be able to delay it for structural issues.
