Cost factors of Texas solar panel installation

Several factors affect the cost of installing solar panels in Texas, including:

  • Size – Larger homes and homes with higher electricity usage need more panels to cover the home's energy demands, which raises the total cost, but may reduce the cost per watt. For larger properties, a solar farm costs $0.90 to $1.30 per watt to build a community solar farm that powers local subscribers.

  • Brand & quality – Most solar panels fall into three categories—High-end, standard, or economy. Choose the best quality your budget allows from a company with an established history. You want a business that will be around for service through your 20+ year panel warranty.

  • Roof type – Your roof type may dictate which type of solar panels you can install and how difficult the installation will be. Complex installations take more time to complete, increasing costs.

  • Installation company – You have your pick of 600+ solar companies with varying prices, services, warranties, and reputation.

  • Permits & interconnection – Permitting and inspection requirements and fees vary by location. Some power companies also have interconnection fees averaging $100 to $200 to join your solar system to the electrical grid.

  • Financing – You'll save the most over the long term if you pay cash, but financing options may allow you to install with little to no money down. Another alternative is a solar lease, where the solar company installs the system for free and you get a discounted fixed rate on the electricity produced.

  • Cleaning & maintenanceSolar panel cleaning costs $150 to $500 on average, depending on the size, location, and cleaning method. Some solar panel installation contracts include an annual inspection and annual or bi-annual cleaning to keep the system running efficiently.

System components

The solar panels are just one part of your home's solar energy system. You also need structures to mount the panels on and one or more solar inverters to convert the energy into a usable form. Some homeowners also opt for battery storage, which further increases the total cost.

  • Panels Microcrystalline panels cost the most but are the most efficient. Polycrystalline panels are cheaper but don't perform as well. Thin film panels are the least expensive and least efficient, with a shorter lifespan of 15 years.

  • Inverters – A solar inverter costs $1,500 to $3,000 installed, depending on the type. This component is typically included in your solar panel system installation estimate.

  • Battery storage – A solar battery storage system costs $5,600 to $11,200 installed (after tax credits) and may be part of your solar panel installation if you wish to have backup power stored for use during an outage.

  • Look for solar contractors who are members of the Solar Energy Industries Association (SEIA) or certified by the North American Board of Certified Energy Practitioners (NABCEP).

  • Look at both large and small solar companies when comparing services, pricing, and warranties. You'll often get a much better price from a smaller, locally owned company; just make sure they've been in business for several years and have a good reputation for quality work.
