Benefits of Solar Energy

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

  • Reduced carbon footprint: Solar is one of the universe's most abundant clean energy sources, meaning you can reduce or eliminate your home's dependence on non-renewable sources.
  • Better energy independence: Solar systems with battery backups work through power outages and emergencies, and you won't have to rely on your power company for your safety and comfort.
  • Smaller power bills: Generating some or all of your own energy will cut power costs long-term.

How To Choose the Best Solar Company in Pasadena

Choosing a company is the first step toward a well-oiled and valuable solar system. Here are some essential aspects to remember while shopping for a solar installer.

The style of solar panels you select decides how much power you can produce. Monocrystalline panels give you the best performance but cost more upfront. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

Additional system add-ons, such as electric vehicle (EV) chargers and battery storage, will increase your overall investment. These will increase your total project price, but they can increase your solar system's efficiency. Not every solar installer provides these additional features, so look for a contractor that has them if it's important for you.

Licensing and Training

All solar energy companies in Texas must have a state electrical contractors' license from the Texas Department of Licensing and Regulation. The Texas State Board of Plumbing Examiners regulates plumbing regulations and licensing standards for solar thermal installers. You should also visit a company's website to learn about its private credentials. Two of the most prestigious are the PV Installation Professional and Solar Heating Installer certificates, granted 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.

Financing Options

Choosing the ideal financing option will impact your overall solar system cost and expected savings. A few of the most common options include leases, power purchase agreements (PPAs), cash payments, 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. Much like a home or auto loan, you'll pay a set monthly rate with potentially $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 typically don’t recommend these two choices because you won't own the system and cannot use solar incentives. Ask each provider you're considering about the payment options it offers. A consultant can help you determine the optimal option for your financial situation.

Frequently Asked Questions About Solar in Pasadena

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

On average, Pasadena homeowners spend approximately $1,421 per year on electric bills. Once you repay your solar array, you could reduce your costs by $972.90 for every kilowatt you produce.

Is solar energy widely available in Pasadena?

Yes, solar energy is reaching new heights in Pasadena. 5,517 homes benefit from solar power, supported by a state solar economy with 10261 workers and counting.

Should I anticipate a boost in my property value after adopting solar power?

Yes, solar panels will raise your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you save on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

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

Most Pasadena homeowners pay back a solar loan in 12.0 years. You can shorten the payback period by paying off extra loan principal each month.

How do I care for my new solar system?

To preserve your solar system's performance, inspections and cleanings every six months are usually adequate. In dry or dusty 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 Pasadena?

A typical Pasadena solar home uses a 7.6-kW panel array, but you might need a bigger system if your energy needs are more demanding. Solar installers will consider your property's power usage and roof shading to determine the right system for you.

What's the difference between a PPA and a solar lease?

After you sign a power purchase agreement, your solar company will not charge to set up and take care of your new panel array. Instead, you'll pay them only for the electricity you generate. Typically, PPAs last for 10–25 years or until you "buy out" of the contract.

If you choose a lease, you'll make set monthly payments.

With both leases and PPAs, you don't own your panels and lose eligibility for some incentives. Further, you'll have to "buy out" or transfer the contract if you sell your home during the term.

Should I get quotes from multiple Pasadena solar companies?

Yes, we advise requesting free solar quotes from three to five companies. You should review each quote and compare warranty details, equipment costs, prework scope and costs, labor fees and financing options. Ensure each quote offers an itemized financial plan and includes your projected payback period.
