Benefits of Solar Energy

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

  • Better energy independence: Solar panels can keep your home running through blackouts and emergencies, giving you additional security. You can use your solar energy anytime with an optional battery backup system.
  • Reduced energy costs: Producing some or all of your own power will spend less on electricity long-term.
  • Reduced carbon footprint: Using clean solar power lowers your dependence on fossil fuels, which release greenhouse gases that damage the environment.

How To Choose the Best Solar Company in Monrovia

The more thorough your company research is, the better your solar system will ultimately perform. Here are some essential aspects to consider while shopping 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 boilers, pool heaters, HVAC, photovoltaic (PV) systems, and water heaters. 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. You should also visit a company's website to learn about its private credentials. Two of the most recognized are the Solar Heating Installer and PV Installation Professional certificates, backed by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Monrovia

The type of solar panels you purchase 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 recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

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

If you're a resident of Monrovia and are looking into a five-kilowatt solar energy system, you could expect to pay 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$1,194
Solar Polycrystalline$931
Thin-Film$544
Solar Battery$764
Solar Home EV Charger$2,865

Financing Solar Energy in Monrovia

There are a plethora of ways to pay for a new solar system, and the right one will reduce your expenses. A few of the most common options include loans, cash payments, power purchase agreements (PPAs), and leases. Though it involves a large up-front payment, cash is the most affordable choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the next best option. As with a home or auto loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for valuable solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) allows you to pay a monthly rate determined by the energy you use, similar to an electric bill. We generally don’t recommend these two choices because you won't own the solar system and cannot use solar incentives. Ask each business you're vetting about the financing options it offers. A representative can help you determine the optimal option for your budget.

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

A 26% federal tax credit applies to new residential solar equipment purchased through 2032. Further incentives may be available through local governments, usually in the form of rebates and special financing programs.

Frequently Asked Questions About Solar in Monrovia

How much energy and money could I save per year by switching to solar?

Most Monrovia homeowners spend about $1,229 on energy each year. Your costs could drop by $1,317.57 for each kilowatt you generate after you pay off a solar array.

How popular is solar energy in Monrovia?

Yes, solar energy is readily available in Monrovia. A growing number of area homes already access solar power on-site or through utility grids, and California has about 74255 jobs comprising its solar economy.

Will solar energy systems raise my Monrovia home price?

Yes, a solar PV system will boost your property value. According to the National Renewable Energy Laboratory, for every dollar you save on energy bills, your home value rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

What if I live in a heavily-wooded or gloomy

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

How do I care for my new solar system?

Solar panels don't demand much maintenance to keep working properly. All you'll need to do is clean and inspect the panels every six months or as necessary in dusty seasons. Solar providers frequently offer maintenance packages to help you in your system's care.

What size should my new Monrovia solar system be?

A typical Monrovia solar home has a 2.8-kW panel array, but you might need a smaller system if your energy needs are more demanding. Solar experts will evaluate your property's energy consumption and roof shading to suggest the proper system for you.

How can I maximize my solar array's performance?

To enhance your solar system's performance, you can try the following strategies:
  • optimize the panels' position with your solar installer
  • regularly clean your solar panels
  • upgrade to a more efficient inverter trim or cut down trees in the way of your panels
  • use energy-efficient appliances

How are traditional solar loans and PPAs different?

A power purchase agreement is a contract between you and your provider. They install, own, and maintain the panels, and you purchase the generated electricity from them for 10–25 years. There will usually be options to buy out early to own your system and extend the agreement.

In contrast, solar loans can come from local banks, specialty lenders, the government and installer. You'll need to pass a credit check to qualify for most of them. While the upfront costs are higher, and you'll be responsible for upkeep, you'll also have full ownership rights and can apply for many more benefits.
