  • Educational approach: Solar technicians must be excellent teachers. They should utilize their years of experience answer your questions on how to maintain your system and improve its performance.
  • Warranty and service offerings: Solar companies should stand behind their systems and services with warranties. We evaluated how each contractor responds to issues and warranty claims, focusing on promptness and customer happiness.
  • Panel quality and brand offerings: The premier solar companies stay up-to-date with new technology, providing equipment from reliable, innovative manufacturers.
  • Professional licenses and credentials: Each company on our list complies with state and city licensing requirements and keeps current with industry best practices. Many of them have been a part of the Monrovia community for over 15 years.
  • Customer reviews and feedback: Most Monrovia solar installers have both favorable and unfavorable reviews. However, a good review ratio indicates a company's trustworthiness and responsiveness to issues.

Benefits of Solar Energy

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

  • Better energy independence: Photovoltaic solar panel systems with battery backups and storage systems function through blackouts and emergencies, and you won't have to depend on your power company for your safety and comfort.
  • Lowered energy bills: Solar panels allow you to generate your own energy to power your home, reducing your regular electricity costs. Going off-grid can eliminate your bills completely. Plus, a significant amount of states offer net metering, which permit you to earn money by selling your unused energy back to the grid.
  • Reduced carbon footprint: Using solar is a surefire way to reduce your carbon footprint and home fossil fuel dependency.

What Solar Incentives Are Available to Monrovia Homeowners?

The state of California offers a range of solar incentives to help lower your solar system costs. Here is a breakdown of available solar programs where you live.

Incentive Amount:

100% of system value; 75% of system value exemption for dual-use equipment

How To Choose the Best Solar Company in Monrovia

The purchase price and performance of solar panels often hinge on the provider that installed them. Consider all of these criteria in your business 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, HVAC, pool heaters, and boilers. Contractors must take a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn a license. Check for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among the solar sector's most reputed trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Monrovia

Your solar modules' style will influence how much energy you can generate. Monocrystalline panels are among the highest quality and cost the most but perform the best. 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 electric vehicle (EV) chargers and battery backup systems. These will increase your total installation cost, but they can enhance your solar system's efficiency. Not every solar contractor offers these optional components, so look for a company that installs them if it's a priority for you.

Most Monrovia homeowners select solar systems designed for five kilowatts (kW) of electrical capacity. These systems run about $17,350 to set up, considering both materials and labor. You can find more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,194
Solar Polycrystalline$931
Thin-Film$544
Solar Battery$764
Solar Home EV Charger$2,865

Financing Solar Energy in Monrovia

There are many ways to pay for a solar energy system, and the right one will reduce your expenses. A few of the most common options include loans, power purchase agreements (PPAs), leases, and cash payments. 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 solar 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 potentially $0 down. Solar leases let you rent your panels for a set monthly rate, while PPAs let you pay only for the energy you use, similar to an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each provider you're vetting about the payment options it offers. A salesperson can help you determine the optimal option for your financial situation.

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

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

Solar System CapacityEstimated Payback period
1 kW1.4 years
2 kW2.7 years
5 kW6.8 years
10 kW13.7 years
