Solar panel systems do not work at night because they are reliant on the sun. Without sunlight to dislodge electrons and stimulate the flow of electricity, solar panels remain dormant. However, while rooftop solar panels may not generate electricity after the sun goes down, there are energy solutions available to ensure your home remains powered – day or night.
Let’s first review how solar panels work.
Understanding how sunlight is converted into electricity is key. Solar panels, also known as photovoltaic (PV) panels, convert sunlight into electrical currents through what is called the photovoltaic effect.
The photovoltaic effect takes place when photons from the sun strike the surface of a solar panel, knocking electrons within the solar panel’s semiconductor material loose. This exposure prompts the generation of voltage within the cell, kickstarting the conversion of energy into electrical power.
A typical solar panel is comprised of multiple photovoltaic cells, each capable of producing 1-2 watts of energy individually. These cells are predominantly crafted from semiconductor materials such as silicon and cadmium telluride which efficiently capture and convert the sun’s rays.
Solar panels generate electricity in the form of direct current (DC). However, most if not all common household appliances (like microwaves, dishwashers, and light fixtures) operate on alternating current (AC) electricity, rendering DC electricity incompatible with direct usage. To bridge this gap, an inverter is used. This essential component facilitates the conversion of DC electricity into AC electricity by altering the current’s direction and frequency. Once this conversion process is completed, the electricity can safely flow into your home, powering your household appliances and devices, or back to the utility grid.
You are probably wondering, if solar panels do not work at night, how do homes with solar panel systems still have power?
The answer is: During the sunniest, peak hours of the day, your solar panel system will often produce more electricity than your home utilizes. This surplus energy is not wasted, if it is stored in batteries or sent back to the utility grid. With proper home storage solutions, you can power your home through the night with an uninterrupted energy supply. From high-technology batteries to innovative storage systems like generators, there are flexible options available, each tailored to suit the unique needs and preferences of your household.
Solar batteries offer a convenient solution for storing excess power and often act as reservoirs. They store excess power generated during peak sunlight hours, which allow you to tap into and use the energy as needed.
Storing energy this way allows little energy to be lost. By coupling your rooftop solar panel system with a battery, you can overcome the challenge of nighttime energy production as solar batteries play a pivotal role in enhancing energy independence and self-sufficiency. This independence provides financial savings as you take control of your household energy usage and costs.
Net metering programs allow you to receive credits for surplus energy generated by your customized solar panel system and exported to the grid through your local utility company. Participating in these available programs and policies allows you to offset your electricity costs by receiving credits on your bill for the excess electricity produced, contributing to local electricity generation. At night, when your solar panel system cannot generate electricity, homeowners can draw from accrued energy to power their homes.
The efficiency and rewards of participating in net metering enable continuous access to power for your home if there are no grid outages. Net metering is a cost-effective benefit of solar energy.
Solar panels work most efficiently under clear, sunny skies; when they receive maximum sunlight exposure. However, there are several factors that can affect productivity, such as angle, intensity, quality, weather, and temperature.
As you can see, there are many factors influencing the overall efficiency of your solar panel system. Many of them are contingent on individual home factors, which is why our solar experts are skilled and knowledgeable in helping you navigate these potential challenges.
