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.

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.

Frequently Asked Questions About Solar in Monrovia

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

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.

Is solar energy easily accessible in Monrovia?

Yes, solar energy is becoming increasingly popular in Monrovia. Some homes already generate solar power on-site or through utility grids, and they're backed by a state solar economy with 74255 job opportunities and counting.

Will solar energy systems raise my Monrovia home worth?

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 if I live in a dark or gloomy

A solar system could still work in bad weather. Your provider will position your panels to capture the most sunlight possible. They might also recommend a back-up power source to keep your system functioning at its best.

What care do my solar panels need, and how often do they need it?

To preserve your solar system's performance, inspections and cleanings every six months are usually enough. In dusty or dry seasons, your panels might need cleanings every few months. Your provider can recommend a maintenance schedule. Its team could also tackle the cleaning for you.

What's the average solar system size in Monrovia?

The average Monrovia solar system size is 2.8 kilowatts (kW). However, your final system size depends on your home's power consumption. Your roof size, panel model, and surrounding shading could also impact your final result. A professional solar provider will consider these factors and determine the right system size for your home.

How can I boost my solar system's performance?

To enhance your solar system's performance, you can try the following steps:
  • 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?

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 continue the contract or purchase the system outright.

You might consider 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.
