Instead, Joe wants to finance his system with $0 down so his Energy Advisor helps him find the right solar loan. He could choose to pay the net system price of $19,640 upfront, and recoup his investment via electric bill savings in less than 10-years. He learns that an 8kW system should generate enough power to cover his energy consumption, and save him roughly $57,000 over 25-years. Joe’s roof has nice sun exposure, so he gets a quote from ’s network of installers. He’s never looked into going solar, but wants to make sure that if a blackout happens again that his home still has some power. The average utility bill for his single-family home is about $170/month. Joe is a homeowner living near Dallas, TX. A homeowner’s battery choice will depend on exactly what circuits should be backed up, the duration for which the homeowner wants that backup power to last, and the typical energy consumption of the user. However, if the home has a battery installed, the solar system can continue to charge the battery while that battery is sending power to the home.ĭifferent batteries have different storage capacities and power capabilities. If a home has solar panels installed without a battery backup, the solar system is turned off during a blackout in order to prevent possible injuries to grid workers. When residential solar panels are coupled with batteries for energy storage, homeowners can keep their homes powered in a blackout. Similarly in Oregon, a large snow and ice storm toppled trees, taking hundreds of power lines down and leaving customers without power for over a week.Ĭalifornia’s high temperatures have consistently resulted in more power consumption than what the grid can support, forcing residents to work through rolling blackouts. Most recently, Texans have suffered through multiple days without power due to freezing weather conditions that have reduced power availability from core sources. Solutions to stabilize the grid are controversial and take significant time and monetary investment. The electrical grid isn’t built to sustain such significant surges in consumption, especially with limited power generation sources, so grid workers must enforce rolling blackouts to prevent long term damage or a complete system failure. In other cases, extreme weather conditions render certain power generation sources unavailable or with a drastically reduced output. The ProblemĮxtreme weather conditions, worsened by climate change, lead to spikes in energy consumption. Regardless of where the blame falls, solar + battery storage is the best option for homeowners who do not want to fall victim to blackouts. Over the last year, the US has seen an unprecedented number of power outages that left millions without power and helpless to extreme weather conditions.
