BIG BEND SOLAR: How sunshine can power the Last Frontier Story and photos by L. G. Lindsay N orwegian playwright Henrik Ibsen has a message for the people of Big Bend: Don’t shoot the messenger! In his 1882 play ENEMY OF THE PEOPLE, Ibsen depicts a small town rent by a realiza- tion the source of its local economy, medicinal hot baths, brings not healing but sickness to tourists who dip into the town’s polluted waters. Sensing a threat to their income stream town eld- ers declare the citizen who pointed out their polluted springs to be an “enemy of the people.” Some 132 years after his play was published Ibsen’s insight 10 Cenizo into the human condition applies to our quest today for new energy sources. The sun shown in West Texas long before we discovered stock dividends, depletion allowances, trade secrets, and fracking. Pre-Columbians in Machu Picchu (Peru) based their civi- lization upon exploiting the sun’s power. No moving parts, no carbon pollution, long system life, and low maintenance: What is not to like about solar photo-voltaic (“PV”) electricity? Had this technology existed in Ibsen’s time, even town elders might have Fourth Quarter 2014 embraced it. Average annual 6.48 peak hours of daily sunshine make Big Bend an ideal region for harnessing the sun. West Texans are self-reliant, but solar PV is not a field in which the inexperienced may dabble. A NAB- CEP-certified solar PV installer is the right guide. He will install the PV sys- tem as well as guide a homeowner through the daunting techno-speak and paper-intensive, pre-installation process. For example, after having heard about the size of my pocket- book, the installer said: “Well, that dol- lar amount will buy a one-kilowatt (“1kW”), pole-mounted, grid-tied PV system which would meet only a por- tion of your home’s power require- ments.” Further, he informed me, I could export back to the grid and sell to my retail electric provider any excess power (i.e., “unconsumed” power) which my system produced during daylight hours. If, for any rea- son, the electric grid went down or failed, the PV electricity generating system would not supply my home’s electrical loads unless I purchased sep- arately a “battery-backup” module.
