Solar can be a big investment. Our goal is to highlight companies best equipped to meet most Modestans’ energy needs.

ConsumerAffairs has heard from thousands of Californians who have already gone through the solar panel installation process. Here’s what Modesto residents should look out for when choosing a solar panel installation company. We’ll also touch on overall costs and ways to save with government incentives.
A typical residential solar panel installation costs $20,084 in Modesto.

Jump to insightSolar scammers in Modesto may falsely claim to be affiliated with a Stanislaus County or California government agency.
Jump to insightA typical solar panel installation costs anywhere from $8,645 to $24,700 in California. Prices in Modesto are comparable, ranging from $8,820 to $25,200.
This doesn’t include an energy storage battery, which sometimes costs as much as the panels: $7,000 to $18,000. A battery lets you store excess energy generated during the day and use it when your panels aren’t producing. It’s worth considering if California’s net metering rates continue to decline or if your area gets frequent blackouts.
System size is the other major solar cost factor. The average Modesto household needs a system with a capacity of 7.97 kW (kilowatt) to fully offset their electricity costs. Depending on how much energy you and your family use, you might need a smaller or larger one.
Average total solar installation costs by system size in Modesto
5 kW | 6 kW | 7 kW | 8 kW | 9 kW | 10 kW | |
---|---|---|---|---|---|---|
Before federal tax credit | $12,600 | $15,120 | $17,640 | $20,160 | $22,680 | $25,200 |
After federal tax credit | $8,820 | $10,584 | $12,348 | $14,112 | $15,876 | $17,640 |
Getting solar panels is like buying a car. Most people pay cash, finance or lease. Similar to leasing, a power purchase agreement (PPA) lets you get the benefits of solar without actually owning the equipment.
» SOLAR PANELS: Buy vs. lease
Solar panels are generally worth it in California if you like the idea of lowering your monthly utility bills. In fact, it’s one of the best states for going solar. The average Modesto homeowner with solar panels can avoid $49,310 in total utility costs over 25 years.
Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.
For a lot of people, the main drawback is the high upfront cost of purchasing and installing the panels and equipment. Assuming an upfront purchase, it takes about 3.9 years to break even (when your savings with solar panels make up for the cost).
The environmental impact of a single homeowner installing solar panels may be relatively small, but when enough people in a city like Modesto go solar, cumulative reduction in air pollution can be significant.
However, the area is prone to earthquakes — make sure your solar installer uses seismic-resistant mounting and anchoring techniques to protect your system from potential damage.
Potential roof problems
As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels again. This is an expensive and frustrating process.
» SHOULD YOU: Replace your roof before going solar?
In our experience, the best solar companies in California have a few things in common: lots of experience, reliable equipment and transparent contracts. Here are some hiring tips.
» TIPS: Get the best solar quotes
The federal solar investment tax credit (ITC) is a significant incentive for most homeowners going solar. It reduces your federal tax liability by 30% of how much it costs to install solar panels.
For example, if you spend $10,000 installing a solar panel system, the ITC is worth $3,000. If you owe $5,000 in taxes, the $3,000 credit reduces what you owe to $2,000.
Don’t get confused: The ITC is a credit, meaning it directly decreases the amount of taxes you owe. This is different from a deduction, which lowers your taxable income. Any unused portion rolls over to the next tax year. However, it’s possible to get a refund check if the ITC credit reduces your taxes to the point where you overpaid during the year.
Residents can also take advantage of statewide solar incentives in California, including Self-Generation Incentive Program (SGIP) rebates for homeowners who install battery storage systems with their solar panels.

No. Under California law, solar installations are exempt from property tax reassessments, meaning the value added to your home by solar panels won’t increase your property taxes.
Monocrystalline and polycrystalline are the most common types of solar panels used in residential installations. In general, monocrystalline panels are considered the best bang for your buck. Cheaper solar panels are typically polycrystalline. The key difference is in materials and efficiency: Monocrystalline panels use pure, single silicon crystals, while polycrystalline panels are made from melted silicon fragments, resulting in different efficiency levels.
Solar panel efficiency is a measure of how well a panel makes electricity. Standard efficiency rates range from 19% to 23%, which means 19% to 23% of the sunlight that hits the panels gets converted into electricity. The more efficient the solar panels you buy are, the fewer panels you need. While more efficient panels cost a little more, you save by buying fewer panels.
A relatively slanted roof with plenty of unshaded space is best. The worst place to install would be on north-facing roofs, especially if those roofs have a high pitch (very steep). Here are a couple of other questions to ask yourself:
As long as your house is a good candidate for solar, it’s at least worth considering. We suggest using NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house. Project Sunroof is a reliable online solar savings estimator.
The ConsumerAffairs Research Team used a research-backed, data-driven approach, which was informed by our expert editors, to choose the best solar companies. We prefer to recommend those with a longer time in business and a solid track record of reliability in Modesto, California. For this guide, we objectively weighted several key features to get our final rankings:
Reviews, ratings and testimonials: 40%
We analyzed solar company reviews by verified solar customers to gauge real-world satisfaction. Companies with generally positive feedback on our site scored highest in this aspect. Those with the most 4- and 5-star reviews by verified Modesto customers were given preference.
Warranties: 20%
A long warranty is important — it shows that a company stands behind its products and services. We compared companies on both equipment and craftsmanship warranty terms. All of our top picks for professional installation have warranties or production guarantees of at least 10 to 25 years.
Equipment selection: 20%
We evaluated each company’s selection of solar panels, storage batteries and inverters. Those with proprietary technology or a wide equipment selection from trusted brands ranked highest.
Financing and payment options: 20%
We gave preference to companies that offer multiple payment and financing options for transparent terms and conditions.
