Benefits of Solar Energy

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

  • Lowered energy bills: Solar panels let you generate your own energy to power your home, reducing your monthly electricity costs. You can eliminate your bills completely if you go off-grid. Plus, a significant amount of states offer net metering, which permit you to earn money by selling your unused energy back to the grid.
  • Better energy independence: Adding a solar battery storage system lets you have trustworthy energy during grid outages and storms.
  • 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 Round Rock

Choosing a company is the first step toward an effective and cost-efficient solar array. Here are some key items to keep in mind while searching for a solar specialist.

Licensing and Training

All solar contractors 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. Look for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among the solar industry's most credible trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Round Rock

The kind of solar panels you purchase determines how much electricity you can generate. Monocrystalline panels and high-quality and 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 the best for large residential installations, but they are excellent accessories for non-traditional roofs.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total installation cost, but they can maximize your solar system's efficiency. Not all solar companies offer these extras, so look for a company that sells them if it's a priority for you.

Generally speaking, it will cost about $16,650 for a five-kilowatt solar array in Round Rock. This table displays more specific prices for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,174
Solar Polycrystalline$915
Thin-Film$535
Solar Battery$751
Solar Home EV Charger$2,817

Financing Solar Energy in Round Rock

Choosing the ideal financing plan will impact your overall solar system cost and expected savings. Common payment options include leases, power purchase agreements, cash payments, and loans. Though it involves a large up-front payment, cash is the most affordable choice because it doesn't accrue interest and qualifies you for incentives. 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 allow you to pay a monthly fee to rent your panels, while a power purchase agreement lets you pay a variable rate based on only the energy you use. We generally don't recommend these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be appropriate in specific circumstances. Look for companies that offer several payment plans to find the right fit for your pocket.

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

You can claim a 26% federal solar tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, local governments and utilities may have their own financing plans and rebates that could reduce your total cost even more.

Frequently Asked Questions About Solar in Round Rock

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

Most Round Rock homeowners spend about $1,422 on energy each year. Your costs could drop by $970.74 for each kilowatt you generate after you pay off a solar array.

How prevalent is solar energy in Round Rock?

Yes, solar energy is becoming increasingly popular in Round Rock. Some homes already benefit from solar power on-site or through utility grids, and they're backed by a state solar economy with 10261 jobs and counting.

Should I expect 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 rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

How can I check my home's solar potential?

One common way to find your home's solar viability is by using PVWatts. This powerful free tool considers local weather and topography, tree cover, system size, and panel efficiency to determine how much electricity your array could generate. However, it's not a substitute for consulting with a local solar installation company, who can create a full estimate with the most updated data.

How do I care for my new solar system?

To protect your solar system's efficiency, inspections and cleanings every six months are usually sufficient. In dusty or dry seasons, your panels might need cleanings every few months. Your technician can recommend a maintenance schedule. Its team could also handle the cleaning for you.

What's the average solar system size in Round Rock?

A typical Round Rock solar home utilizes a 7.5-kW panel array, but you might need a larger system if your energy needs are more demanding. Solar installers will consider your property's energy consumption and roof shading to determine the appropriate system for you.

How does "net metering" work, and do I need to participate?

Net metering is a billing mechanism that credits solar homeowners for any excess electricity they generate and send back to the grid.

Some states or energy providers require you to participate in net metering when purchasing your solar system, while others give you a choice. Either way, once you sign up, you'll earn a check or bill credit for your excess generation at a wholesale or retail rate.

What's the difference between a PPA and traditional financing?

A power purchase agreement (PPA) is an agreement 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 extend the agreement and buy out early to own your system.

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