Benefits of Solar Energy

Solar energy has multiple advantages that will enhance your home for years to come.

  • Reduced carbon footprint: Embracing solar is a surefire way to decrease your carbon footprint and home fossil fuel dependency.
  • Better energy independence: Adding a battery backup lets you have trustworthy energy during grid outages and storms.

How To Choose the Best Solar Company in San Marcos

Choosing a company is the first step toward a well-oiled and valuable solar energy system. Consider each of these criteria in your service provider search.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar water heaters, photovoltaic (PV) systems, boilers, pool heaters, and HVAC. Contractors must take a highly comprehensive educational series, gain four years of experience as an apprentice or journeyman, and pass written exams to secure a license. Check for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar sector's most credible trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in San Marcos

Your photovoltaic panels' model will influence how much electricity you can produce. Monocrystalline panels perform the best but cost the most. Polycrystalline panels offer you a budget panel with a traditional design, but at the cost of less power generation. Thin-film panels have a low cost and are excellent for non-traditional roofs, but aren't recommended for large home installations.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total project price, but they can increase your solar system's performance. Not all solar providers offer these extras, so look for a company that installs them if it's crucial for you.

If you're a resident of San Marcos and want a five-kilowatt solar energy system, you could plan to spend about $17,350 for materials and labor. See more information on specific component and panel costs in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,226
Solar Polycrystalline$956
Solar Battery$784
Solar Home EV Charger$2,942

Financing Solar Energy in San Marcos

There are various ways to pay for a new solar system, and the right one will help you decrease overhead. A few of the most common options include power purchase agreements (PPAs), cash payments, loans, and leases. We suggest making a cash payment or securing a solar loan for the highest return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also have full ownership of your system and can apply for solar incentives to reduce your total costs. Solar loans are another solid option if you don’t want to make a big initial investment. You can pay for your system in installments while still enjoying energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) lets you pay a monthly rate based only on the energy you use, like an electric bill. We usually don’t recommend these two options because you won't own the panels and are disqualified from using solar incentives. Ask each company you're vetting about the payment plans it offers. A representative can help you determine the most suitable option for your budget.

The table below lists the average payback periods for different capacities of solar systems in San Marcos.

You can claim a 26% federal tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, utilities and local governments may have their own financing plans and rebates that could reduce your total cost even more.

Frequently Asked Questions About Solar in San Marcos

How much money could I save by going solar in San Marcos?

Most San Marcos homeowners spend about $1,659 on energy each year. Your costs could drop by $1,637.07 for each kilowatt you generate after you pay off a solar array.

How common is solar energy in San Marcos?

Yes, solar energy is on the rise in San Marcos. Some homes already generate solar power on-site or through utility grids, and they're fortified by a state solar economy with 74255 workers and counting.

Will solar panels increase my San Marcos home price?

Yes, new solar systems lead to higher property values according to the National Renewable Energy Laboratory (NREL.) Homeowners could project a $20 property value increase for each dollar they save on energy. Therefore, $600 in energy savings could increase your home's value by $12,000.

What can I do to estimate my home's solar viability?

To determine your home's solar readiness, nothing substitutes for a comprehensive quote from a local solar contractor. However, you can use the PVWatts tool for a simple solar viability estimate based on public data, including system size, tree cover, local weather and topography, and panel efficiency.

How long does the solar installation process take?

Your solar job's duration will depend on its size and complexity, as well as San Marcos' permit and inspection procedures. It could take several weeks to a couple of months on average.

What is the average payback period for San Marcos solar panels?

Most San Marcos homeowners pay back a solar loan in 7.4 years. You can shorten the payback period by paying off extra loan principal each month.

How are a solar lease and PPA different?

Choosing a lease means your solar provider will handle panel maintenance while you make fixed monthly payments. Power Purchase Agreements differ slightly because you pay for just the electricity you produce.

You don't own the panels with either option, though you can choose to "buy out" of the contract for a fee.

Should I get quotes from multiple San Marcos solar companies?

It's prudent to collect three or more estimates before committing to a single solar provider. This lets you evaluate product quality, warranty options, customer feedback, and pricing. It also helps you gauge a contractor's knowledge, responsiveness and reliability, all of which are positive signs.
