A Homeowner’s Guide to Buying Solar Panels in Southern California

From evaluation to installation — how to make informed decisions when going solar

Southern California continues to lead the nation in solar adoption—and for good reason. With long days of sunshine, high utility rates, and supportive state policies, solar energy offers significant financial and environmental benefits for homeowners in the region.

If you’re considering solar for your home, this guide will walk you through the steps of buying a solar energy system, from researching local providers to selecting equipment and understanding payment options. We’ve helped thousands of homeowners in Los Angeles, Orange County, and beyond transition to clean, cost-effective energy—and we’re here to help you do the same.

Step 1: Assess Whether Solar Makes Sense for Your Property

Before reaching out to installers, determine whether your home is a good candidate for solar. Key factors include:

• Roof orientation and tilt: South- and west-facing roofs typically produce the most energy.
• Shade exposure: Limited shading ensures optimal energy production throughout the day.
• Roof condition: If your roof will need replacement within 5–10 years, address that before installing panels.
• Electricity usage: Homes with higher annual energy bills (common in areas like Inland Empire and San Diego) often see faster returns.

At this stage, it’s important to have a general idea of your home’s solar potential. US Power provides custom system designs only after you decide to move forward with us—ensuring your proposal is tailored, accurate, and based on a commitment to quality from both sides.

Step 2: Get Multiple Quotes and Make Us Your Last

Solar systems vary by size, quality, design, and pricing. Getting multiple quotes ensures you're not overpaying—and helps you compare previous quotes to identify ways to maximize your savings..:

• System size (kW)
• Estimated annual production (kWh)
• Equipment brands
• Warranty terms
• Total project cost

Local experience matters. We specialize in Southern California installations and tailor each proposal to local building codes, utility guidelines, and climate conditions.

Step 3: Review Installer Credentials and Track Record

An experienced installer is critical to the long-term performance and reliability of your system. As you evaluate providers, ask:

• Are they licensed and insured in California?
• How long have they been operating in Southern California?
• What do verified customer reviews say?

With thousands of completed installations across SoCal and an established reputation for professional solar service and post-installation support.

Step 4: Understand Your Equipment Options

Panel and inverter technology has advanced significantly in the last decade. When reviewing proposals, pay attention to:

• Panel efficiency and degradation rate
• Manufacturer warranties (ideally 25 years)
• Temperature coefficient (important in hot climates like Riverside or Palm Springs)

Recommended Solar Panel Brands:

• Q CELLS – High-efficiency panels with reliable performance and competitive pricing.
• REC – Durable, efficient, and well-suited for coastal areas like Orange County and San Diego.
• Maxeon (SunPower) – Industry-leading in efficiency and warranty, ideal for homeowners prioritizing long-term value.

US Power works with these Top-tier solar panels manufacturers to ensure every system meets our quality standards.

Step 5: Choose a Payment Method That Fits Your Goals

There are several ways to finance your solar system:

• Cash Purchase – Yields the highest long-term savings and fastest return on investment.
• Solar Loans – Allows for zero-down installation while still qualifying for solar tax incentives.
• Leases/Power Purchase Agreements (PPAs) – Lower upfront costs, but typically offer reduced long-term savings and limited ownership benefits.

Step 6: Finalize Your Contract and Prepare for Installation

Once you've selected an installer, the process moves quickly:

1. Sign a detailed contract with all terms and specifications.
2. Schedule a site visit to confirm design and gather permit-related information.
3. Submit paperwork for city permits, utility interconnection, and incentives (handled by your installer).

US Power manages the full administrative process, ensuring compliance with your local jurisdiction—from LA County to San Bernardino.

Step 7: Installation and Activation

The physical installation of solar usually takes 1 to 3 days, depending on your roof’s complexity. After installation:

• Your local utility will conduct an inspection and grant Permission to Operate (PTO).
• Once approved, your system is activated and begins producing clean energy.

From contract to activation, the full timeline typically ranges between 4 to 8 weeks, though this can vary depending on your city’s permitting process.

What Happens After Installation?

With your solar system online, you’ll immediately reduce your reliance on the grid and begin saving on your monthly energy bills. Depending on your utility provider and net metering status, excess energy may be credited to your account.

You’ll also benefit from:

• Increased home value
• Reduced exposure to rising energy rates
• A lower carbon footprint

US Power provides post-installation support, performance monitoring, and warranty assistance—so you’re not left on your own once the system is live.
