Benefits of Solar Energy

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

  • Lowered energy bills: Solar panels let you generate your own energy to power your home, lowering your regular electricity costs. You can eliminate your bills completely if you go off-grid.
  • Reduced carbon footprint: Solar is the universe's most abundant clean energy source, meaning you can lower or beat your home's dependence on "traditional" sources.
  • Better energy independence: Solar systems with energy storage function through blackouts and emergencies, and you won't have to rely on the power grid for your safety and well-being.

How To Choose the Best Solar Company in Modesto

The more comprehensive your company investigation is, the better your solar system will ultimately function. Here are some key items to consider while searching for a solar installer.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar HVAC, water heaters, photovoltaic (PV) systems, boilers, and pool heaters. Contractors must take a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn licensure. Solar companies can also obtain certifications from standards organizations and trade groups. The most recognized ones in the industry come from the North American Board of Certified Energy Practitioners. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Modesto

The type of solar panels you select determines how much energy you can generate. Monocrystalline panels cost more but give you the best performance. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. Thin-film panels aren't meant for large home installations, but they're excellent for small projects like sheds and RVs.

If you'd like to charge an electric vehicle (EV) or use your solar power in inclement weather, you can pay extra for add-ons. By choosing the right components, you can make your system more productive and convenient to use. Not every solar contractor includes these optional components, so look for a company that sells them if it's essential for you.

Generally speaking, it costs about $17,350 for a five-kilowatt solar array in Modesto. This table displays more specific costs for different solar panel types and system components in your area.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,128
Solar Polycrystalline $880
Thin-Film $514
Solar Battery $722
Solar Home EV Charger $2,708

Financing Solar Energy in Modesto

There are many ways to pay for new solar panels, and the right one will minimize your overhead. A few of the most common options include leases, cash payments, power purchase agreements (PPAs), and loans. Most solar experts recommend a cash payment or using a solar loan. Cash payments require a large up-front sum, but they save you from paying interest, grant you system ownership, and qualify you for cost-saving incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Similar to a car or home loan, you'll pay a set monthly rate with as little as $0 down. Solar leases allow you to pay a monthly rate to rent your panels, while a PPA lets you pay a variable rate based on only the energy you use. We generally advise against these options since you won't own your system and are disqualified from solar incentives, but they might be suitable in certain circumstances. Ask each provider you're vetting about the payment plans it offers. A staff member 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 Modesto.

The IRS allows you to claim a 26% federal tax credit on the full cost of the solar system, so long as you purchase it before 2032. Municipal authorities and utilities might also offer their own incentives, financing programs, and rebates that could save you more money.

Solar System Capacity Estimated Payback period
1 kW 1.4 years
2 kW 2.7 years
5 kW 6.8 years
10 kW 13.7 years

Frequently Asked Questions About Solar in Modesto

How much money could I save by going solar in Modesto?

On average, Modesto homeowners shell out roughly $1,313 per year on electric bills. Once you repay your solar array, you could save $1,727.73 per kilowatt you produce.

Is solar energy readily available in Modesto?

Yes, solar energy is gaining popularity in Modesto. Some homes already benefit from solar power on-site or through utility grids, and they're backed by a state solar economy with 74255 job opportunities and counting.

Will a solar PV system increase my Modesto home worth?

Yes, new solar systems translate 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.

Could I still use solar power if I live in a dark, rainy, or wooded area?

Even if your property has high tree cover, you could still benefit from solar energy. Your technician will maximize your system's performance by choosing the proper site for panels, installing a battery backup system, cleaning them regularly, and positioning them to capture the most sunlight throughout the year. This way, you can store solar power and utilize it as necessary.

How long will a common solar system last?

Modern solar systems are built to last. The average panel provides 25 years of reliable power. Budget panels tend to last shorter than premium models.

How long does it take to pay back a solar loan in Modesto?

Most Modesto homeowners pay back a solar loan in 7.0 years. You can shorten the payback period by paying off extra loan principal each month.

What are the signs I shouldn't use a particular solar company for my job?

Even the most renowned Modesto solar companies will have both favorable and negative reviews. To make the most informed decision possible, focus on these warning signs to know if a company isn't worth your attention:
  • High-pressure sales tactics
  • Being evasive about training and credentials, warranties, cost and references
  • Inflexible options
  • Superficial, rushed site evaluation
  • Limited customer feedback

How are traditional solar loans and PPAs different?

The main differences between a power purchase agreement and traditional financing are that you pay a fluctuating monthly rate based on your energy usage and don't own your system. Your service provider installs and maintains the panels, and you pay for the generated electricity for 10–25 years. Afterward, you can extend the agreement or purchase the system outright.

You might look into a PPA if you don’t want to be responsible for maintenance and don’t want to invest in a system, but keep in mind you won’t be paying toward ownership or be able to access any cost-saving solar incentives. Many solar experts don’t recommend PPAs. Our guide covers other financing options above.
