The Role of Solar Energy in Emergency Preparedness During Power Outages

An increased reliance on the electrical grid and the higher risk of severe storms mean we must prepare for power outages, which can lead to severe losses. In the past, many of us relied on flashlights and electric generators to get through outages, but today, solar energy offers a longer-lasting, more reliable solution.

Solar energy is ideal for outages because it relies on the sun, a source that is not dependent on utilities. However, it presents some limitations. This article will discuss how solar energy can help with emergency preparedness during power outages and how to overcome limitations that may interfere with energy production.

Navigating the Higher Risk of Outages

The modern world should prepare for an increased risk of outages due to increased electricity use and severe storms. Here are ways they can interfere with energy production.

High Energy Demand

Due to high energy demand, power outages can occur. They are especially likely to occur during the summer when everyone turns on their air conditioning.

Historically, power outages have been an uncommon cause of power outages, but they are more likely to occur today due to global warming. Higher temperatures mean more people will run their air conditioning more often.

Another contributor is the increased use of electronics. Due to technological advancements like computers, software, cell phones, and game consoles, people use electricity more than ever. These devices tax the grid, making outages more likely.

Storms 

Storms are a more common cause of power outages. According to Climate Central, about 83% of power outages between 2000 and 2021 were related to weather events. Thanks to climate change, that number has increased by almost 80% since 2011.

Climate change warms the oceans, providing more energy to fuel storms with high wind speeds and heavy rainfall. These conditions combine with a warmer atmosphere that holds more moisture and rising sea levels that exacerbate storm impact. As a result, we can expect more frequent severe storms that cause power outages.

Other Causes of Power Outages

• Trees: Trees can fall and inadvertently hit power lines, causing an outage. These incidents are more likely to occur during storms.

• Animals and Wildlife: Animals and wildlife chew through wiring or forage for food or nest in electrical wiring, causing outages.

• Motor Vehicle Accidents: Cars may accidentally hit power lines, shutting down power.

• Construction Work: Workers can accidentally cut into underground lines and utility poles.

• Public Incidents: Power outages can occur if someone accidentally damages equipment during yard work. Some may even damage utility lines purposefully as an act of vandalism.

• Cyber Attacks: Some terrorist or foreign power groups may launch a cyber-attack that takes down power systems.

• Planned Power Outages: Utility companies may plan power outages for testing and maintenance.

What are the Impacts of a Power Outage?

A power outage is more than an inconvenience. Impacts include:

·  Effects on Business: A power outage can bring businesses to a halt. Companies will lose revenue and could even deal with data loss and damaged equipment. According to Atlassian, it can cost a mid-sized company may spend $1 million on recovery efforts.  

·  Medical Emergencies: Many people use electricity to keep medications cool and operate medical equipment. These people could die without electricity, especially considering limited communication and transportation during some outages.

·  Food Loss: When the electricity goes out, the refrigerator stops working. It cannot keep food fresh, leading to spoilage and substantial losses.

How Solar Helps During a Power Outage

Power is reliant on the grid. Solar power, on the other hand, is reliant on the sun. It’s available whenever the sun is shining.

Solar homes and work buildings can continue functioning during an outage. Sun energy can also power shelters that provide housing and medical services for people during an emergency.

Batteries and generators may also help people prepare for an outage, but batteries are unreliable. Electric generators require gas and can pollute the environment. They are also quite loud.

Solar energy is always there for you. People may obtain energy from solar panels or solar generators. Solar generators are quieter than their gas counterparts and do not produce pollution.

Battery Storage

Battery storage is essential during a power outage. Systems with batteries can store power when the sun isn’t out.

Make the most of your stored energy by recharging your battery during daylight hours. You should also purchase a reliable, high-capacity battery. 1-14 kWh is recommended.

Consider Critical Loads

Some appliances use more energy than others. Limit your use of high-consumption appliances and reduce appliance use to conserve energy. Here are some tips to keep in mind.

• Prioritize Essential Appliances: For example, your refrigerator is necessary to prevent food and medication from spoiling. Most people also need a Wi-Fi router. Ensure your medical devices are powered in the event of an emergency.

• Turn on Key Lights: Lighting is necessary, but you can save power by limiting the number of lights you turn on. Turn on enough lights to illuminate your space, but avoid excessive power use.

• Limit Your Use of High-Capacity Loads: High-capacity appliances include ovens, washing machines, and HVAC systems. Limit your use of these systems. If you must use them, keep energy efficiency in mind. For example, you can keep your HVAC system at a reasonable temperature and use only cold water in your washing machine to save energy.

• Unplug Items Not in Use: Plugged-in items draw electricity even when not turned on. Unplug them to conserve energy.

• Use Energy-Efficient Bulbs: LED bulbs use less energy, allowing you to make the most of your available power.

• Consolidate Refrigerated Items: If you have two or more refrigerators in your home, consider consolidating your food in one unit so you use less energy.

  
  

Consider Maximizing Energy Use During Installation

 Work with your installers to optimize your panels to get you through a power outage. Here are some things to keep in mind.

Purchase Efficient Panels

 The more efficient your panels are, the better they will absorb energy that can be used to power your home. Efficiency varies by panel type.

Monocrystalline panels are typically the most efficient. However, they may be excessive for home use. Polycrystalline panels may offer the ideal combination of value and cost-effectiveness.

The manufacturer also matters. Some solar panels are manufactured to absorb optimal sunlight, while others aren’t as effective.

According to Solar Reviews, most solar panels have an efficiency rating of 19% to 21%. However, thanks to updated technology, you may purchase solar panels with an efficiency rate closer to 22%.

Consider Orientation and Angles

 Your installer should install your solar panels considering the optimal orientation and angle for capturing sunlight. The orientation is the direction your panels face: north, south, east, and west.

Generally, homes in the Northern Hemisphere should have south-facing panels, while Southern Hemisphere homes should have north-facing panels. However, some experts state that west-facing panels have helped reduce grid reliance.

To capture optimal sunlight, the panel’s angle should be closer to vertical in the winter and more elapsed in the summer. Consider installing your panels with sun-tracking technology to ensure they follow the sun as it moves across the sky.

Shading Concerns

 Ensure your panels are installed to absorb optimal sunlight, considering possible blockages. For example, a nearby tree or structure may interfere with the panels’ sun absorption. You may be able to remove or trim trees to ensure maximum absorption.

Structures are more challenging to deal with. You may consider a ground-mounted system if your installer cannot install panels to absorb sunlight despite nearby structures.

Maintain Your Panels

Dust and debris can accumulate on panels, interfering with their ability to absorb sunlight. According to Consumer Affairs, a buildup can cause panels to lose 25% to 30% efficiency.

 Clean panels regularly with water, a soft cloth, a sponge, or a brush for optimal absorption. Avoid abrasive materials.

If you have trouble cleaning your panels, a professional can assist.

Choose a High-Quality Inverter

Your inverter converts direct (DC) energy into alternating (AC) electricity, which powers your home. To improve your system’s overall production, choose a high-quality inverter.

Monitor Your System

Many installers provide monitoring tools to measure your system’s production. These tools allow you to identify issues and fluctuations and address them immediately. Key monitoring factors include daily energy output, voltage levels, and error messages.

Consider Advanced Technologies

 The following technologies will ensure your panels absorb optimal sunlight during an outage.

• Microinverters and Power Optimizers: These technologies reduce the impact of shading, uneven soils, and panel mismatch, allowing your panels to operate efficiently. A smart inverter with maximum power point tracking (MPPT) will also enhance performance.

• Solar Cell Technology: Choose panels with advanced solar cell technology, such as CIGS, CdTe, perovskite, or multi-junction cells, which achieve a higher output than traditional silicon PV cells.

• Solar Trackers: Solar trackers automatically adjust your panels’ orientation and tilt to track the sun as it moves across the sky.
