How To Choose the Best Solar Company in Round Rock

The price and performance of solar panels often depend on the solar company that mounted them. Consider each of these elements in your service provider search.

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. Solar installers can also earn certifications from trade groups and standards organizations. The most recognized ones in the industry come from the North American Board of Certified Energy Practitioners. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Round Rock

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power. Polycrystalline panels produce less power, but start at a more budget-friendly price point. 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 components, such as electric vehicle (EV) chargers and battery storage, will increase your overall costs. However, they might make your solar system more efficient and convenient to use. Not every solar company includes these additional features, so look for a provider that sells them if it's important for you.

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

Solar Panel Cost Average 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

Solar providers use multiple different financing options to increase your savings and lower your costs. Though some providers offer unique payment plans, the most common are solar leases, power purchase agreements (PPAs), solar loans and cash payments. We advise paying with cash or using a solar loan for the highest return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also own your system and can apply for solar incentives to minimize your total costs. Solar loans are another good option if you don’t want to make a big initial investment. You can pay for your system in monthly installments while still enjoying energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases let you use your panels for a fixed 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 don't grant you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each business you're vetting about the payment plans it offers. A team member 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 Round Rock.

You are eligible for a 26% federal tax credit for new solar energy equipment until the year 2032. Local and state governments and utility companies might also offer rebates, discounts, and unique financing solutions that could save you more.

Solar System Capacity Estimated Payback period
1 kW 2.1 years
2 kW 4.2 years
5 kW 10.6 years
10 kW 21.2 years

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.
