Prepare For Public Safety Power Shutoffs

Dec 22, 2020

Solar Power is becoming an increasingly popular alternative to conventional power. One benefit to having solar energy is the independence from the public electrical system. Solar panels are designed to ensure your home or property can have around the clock access to clean and renewable energy. Whether fire season or not, it can be necessary to back up your power and have a solar power reserve. This article explains some steps to prepare for power shut offs and backing up alternative sources of energy.

What Causes A Temporary Power Shut Off

There are times, especially during wildfire season and when heat waves are prominent, in which the power company temporarily shuts off power to the electrical grid. Losing electricity is inconvenient at best and dangerous at worst. People with medical needs, the elderly, and other susceptible groups of people should not be without electricity for long. Utility companies do not make the decision lightly. Usually, these high-risk times are in the summer and fall. This shutdown ensures public safety by preventing forest fires due to an electrical fire caused by utility lines. Intense weather conditions, such as strong winds, dry vegetation, and low humidity, can prompt a decision to turn off the power. The wind speeds are often forecast to be 60-70 miles per hour or more to trigger a PSPS event. These public safety events have been effective in areas where utility companies temporarily shut off the power. 

What Is Solar Power?

Solar power works by harnessing the energy from the sun's rays. Home installed solar energy consists of a series of solar panels. Within the panels are solar cells. Cells are often made from silicon. Silicon acts as a semiconductor, and electricity is subsequently generated. When the sun is shining, beams of light enter the cells and are absorbed. This process is called the photovoltaic effect. Specialized technology helps convert it to the correct type of energy to flow through the building's electrical system.

If there is no storage system in place, excess and unused energy is fed back to the primary power grid. Installing  Sunpower  solar panels breaks the dependency on the local utility companies. Solar energy is cost-effective, a source of clean energy, and efficient. There are many practical reasons to switch to solar power.

Prepare For A Power Shutoff For Public Safety

A planned power shutoff is to prevent forest fires started by electricity during prime fire triggering conditions. The decision to shut off power for a PSPS event is usually begun 5-7 days before the high-risk conditions are expected. Notices are sent over the following days to ensure public awareness. A shutoff can last for just a few hours or up to several days. 

With or without solar power, people and families should take some steps to prepare for a power outage. These steps are valuable during any interruption to everyday life, so they are helpful to have established regardless of electrical shutoffs. 

  • Always have a safety plan for both people and pets.


  • Keep an emergency supply kit handy.


  • Keep cell phones charged and have backup chargers.


  • Invest in a battery-operated radio.


  • Keep flashlights ready with fresh batteries.


  • Have a plentiful supply of batteries.


  • Keep cash on hand. ATM's will not operate during a power shortage.


  • Keep gas tanks full.


  • Have a fully stocked first aid kit.


  • Make sure any special medical devices and medicines are well stocked and charged for a power shutoff.


  • Keep some bottled water stored, enough for one gallon per day per person and pet.


  • Freeze containers of water in advance. People can use frozen jugs of water to keep food cold.


  • Keep canned and boxed food stored along with a manual can opener.

Will a solar power system operate during a power shutdown?On its own, a solar system will not operate during a power shutoff. For this reason, a backup battery or storage source is needed to store the solar energy harnessed to be used when required. During a blackout, most buildings and homes with a solar power system and the backup battery or storage system can keep functioning like normal. A solar system with a battery backup is designed to transfer between power mode and battery mode automatically. 

Backup Power System For Solar Energy

A backup power system is a necessary companion to a solar energy system for energy storage. There are a few ways to provide solar energy storage . A backup, such as a solar battery, will keep your home running on clean, renewable energy, even during a public power shutoff. With this system in place, you will relieve the stress of the planned power outages and will be able to maintain control. With a system such as a battery for backup, the amount of energy saved and when the customer can use it is within their control.

High wind velocity can cause power lines to be damaged by falling trees or debris or damaged by extreme winds directly, and a downed power line can spark a fire. The power affected by a downed line can span hundreds of miles. Likewise, a planned power shutoff can span hundreds of miles and sometimes to areas that are not experiencing the intense weather. Having a solid emergency plan in place, emergency goods on hand and a solar energy system with an energy backup in place can help alleviate the stress and uncertainty that might come with a public safety electricity shutoff. Planned power shut offs are known to prevent wildfires and will continue to be scheduled during heat waves or times of high fire risk conditions. Solar power energy with backup can provide a cost-effective way to survive these episodes with minimal stress.

When deciding which solar panels are right for your home, there’s more to consider than just pricing. Sure, a low-cost option might seem attractive at first glance but will your investment be worth its weight 10, 20 or even 30 years down the line?

In the past, there was only one answer to the question, “What’s the best direction for solar panels to be pointed?” In the Northern Hemisphere, that direction was south. Because the sun shines directly over the equator most of the time, south-facing solar panels have an opportunity to collect more sunlight and generate more solar energy.

While generating power from the sun is without cost, the technology behind this process is not. The reality is solar panels are an investment – much like a home – that has an upfront cost but pays off in the long term. The installation can be compared to a small construction project and each module contains multiple parts to make everything run smoothly. So, how does a homeowner ensure that taking a chance on clean energy solutions will be worthwhile?

Buying or selling a home is a big change for any family. There are several things to consider during the process, making the question of what to do with your solar system feel daunting. But it doesn’t have to feel this way. Realtors and homeowners are also increasingly savvy about promoting the value of solar power when it comes to home sales and purchases. But even without that expertise, the ins and outs of buying and selling homes with solar panels aren’t that complicated.

Renewable energy sources are by definition constantly replenished. Fossil fuels like coal or gasoline burn up and are gone, but the sun keeps shining and the wind keeps blowing no matter how many homes use them to make electricity.
