However, electricity prices are going up in those areas as our state's population grows (just last month, Bloomberg reported on our wholesale power prices reaching the $9,000 per megawatt-hour cap). At the same time, solar is more affordable than it has ever been, falling 34% during the past five years according to SEIA.

Together, those forces mean that solar is now an attractive investment for businesses in the competitive electricity markets, which are finally catching up to where the municipally owned utilities such as San Antonio and Austin have been for several years.

GlobeSt.com: What is the Federal Solar Tax Credit and how can it benefit businesses considering the move to install solar?

Biggart: The solar Investment Tax Credit makes it much more affordable for businesses to go solar. It allows businesses to deduct 30% of the total cost of an installed solar PV system from their 2019 federal taxes. This tax credit is set to begin a three-year stepdown next year, moving to 26% in 2020, 22% in 2021 and 10% thereafter for commercial systems. In order to take advantage of the 30% tax credit, businesses must begin construction or at least pay 5% of the total project cost in 2019. Businesses can also take advantage of depreciation tax benefits that make the upfront cost of solar even more affordable. The average payback on a commercial solar project in Dallas is between four and eight years.

GlobeSt.com: When does it make sense for a business owner to consider solar?

Biggart: Any business that owns their property, has sufficient unshaded roof or space on the property for a carport or ground mount system and has tax liability should consider going solar.

GlobeSt.com: What's the future of solar in Texas?

Biggart: We are seeing phenomenal growth this year as businesses and homeowners focus on the 30% tax credit, but we believe that the solar industry will continue to grow in Texas even as the Investment Tax Credit steps down. Solar costs continue to be driven downward because of the economies of scale coming primarily from utility-scale solar farms.

Solar is a great way to stabilize the Electric Reliability Council of Texas (ERCOT) electric grid in Texas, given that its production window aligns well with peak demand. Solar energy is viewed positively by consumers of all stripes. It has more support among Americans than any other energy source, with 80% saying the US should put more emphasis on solar power (the next highest is wind energy at 70%), according to Gallup.
