Solar panels generate electricity through a process called photovoltaics (PV), which converts sunlight into usable power. Each solar panel is made up of multiple solar cells that absorb sunlight and create an electric current.
When sunlight hits these cells, it excites electrons, generating direct current (DC) electricity. However, most homes and businesses use alternating current (AC), so an inverter is used to convert DC into AC electricity. Once converted, this energy can power appliances, lighting, and other electrical devices.
Modern solar technology is based on the photoelectric effect, first discovered by physicist Alexandre Edmond Becquerel in 1839. Since then, advancements in solar cell efficiency and panel durability have made solar power one of the most sustainable and accessible energy solutions available today.
Yes, solar panels can still produce electricity even when it’s cloudy, rainy, or snowy. The sun emits ultraviolet (UV) light throughout the day, and this light can pass through clouds, providing enough energy for the solar panels to function.
However, since the panels receive less direct sunlight in these conditions, their efficiency may be reduced. On overcast days, energy production can drop by about 10% to 15% compared to a clear, sunny day. Despite this, solar panels remain a reliable energy source in various weather conditions.
Bifacial solar panels capture sunlight on both the front and back sides, increasing energy production by up to 30% compared to traditional panels. This dual-sided design allows them to harness reflected sunlight from the ground or surroundings, improving efficiency.
Key Benefits:
Bifacial panels offer a more efficient and durable solution for solar energy capture.
Yes, solar panels can still generate electricity even when it snows. This is because they absorb sunlight, not heat, to produce power. As long as some sunlight reaches the panels, they will continue to function.
A light layer of snow is usually not an issue, as wind can blow it away or it can melt and help clean the panels. However, heavy snow accumulation may reduce efficiency by blocking sunlight or slightly altering the panel’s angle. High-quality solar panels, like those from CW Energy, are designed to withstand extreme conditions, handling up to 5400Pa making them highly durable even in heavy snowfall.
Solar panels are designed to withstand various weather conditions, including extreme heat, heavy snow, and even hurricanes. Most systems are tested for durability in extreme conditions, and modern panels are built to endure high wind speeds and snow loads up to 5400 Pascal. However, in the event of severe storms, it’s a good idea to inspect the panels afterward to ensure there are no damages. If you live in an area prone to extreme weather, consult your installer for additional protection options.
If your solar panels aren’t generating enough electricity, it could be due to various factors like weather, seasonal changes, or shading. However, most solar systems are designed to provide backup from the grid or incorporate energy storage options like batteries to ensure your home remains powered. If your system is still underperforming after these factors are accounted for, it’s best to contact your installer for an inspection and troubleshooting.
Solar panels can significantly lower your electricity costs by generating power for your home, reducing or even eliminating your reliance on grid electricity. The exact savings depend on factors like your system’s size, panel efficiency, local climate, and available incentives or rebates.
In the U.S., the average household spends around $150 per month on electricity. If your solar system covers your full energy needs, you could save up to $1,800 per year. Additionally, many regions offer tax credits and incentives that can further increase your long-term savings.
Yes, a home can run entirely on solar power, but it depends on several key factors. Your home's size, energy consumption, and the capacity of your solar system all influence whether solar alone can meet your needs. Larger homes typically require more panels, while smaller homes may need fewer.
If your energy usage is higher than what your solar system produces, adding battery storage can help store excess power for nighttime or cloudy days. To determine the best setup for your home, consulting a solar professional is the best way to ensure maximum efficiency and reliability.
The actual installation of solar panels typically takes just a few days, and in some cases, it can be completed in one day. However, the entire process — including roof assessment, installation, and final approvals — can take anywhere from two to six months depending on various factors. Here’s a breakdown of the steps involved, most of which will be handled by your chosen installer:
System Design:Your installer will assess your roof’s dimensions, angle, and shading to design the optimal solar system that suits your energy needs.
Site Assessment: The installer will evaluate your roof's condition, checking for any necessary repairs before installing the panels.
Permitting: Your installer will manage the paperwork and permissions required to proceed with the construction.
Installation: Depending on system size, weather, and installer expertise, the installation may take a day or longer to complete.
Final Inspection & PTO: Once installation is complete, local authorities and your utility company will conduct an inspection. After approval, they will grant you permission to use the system. This final approval process can vary based on your utility provider.
In the Northern Hemisphere, to maximize sun exposure, solar panels are ideally positioned to face true south, which refers to the geographic south direction, not magnetic south. If a true south-facing installation isn't feasible, east or west orientations are also effective. Installing panels on both the east and west sides of your roof can capture sunlight during different times of the day, improving overall energy production.
Solar panels require very little maintenance. To keep them performing efficiently, periodic cleaning may be necessary, especially if you live in an area with dust or heavy rain. You should also have your system inspected every few years to ensure everything is functioning properly. Many systems come with monitoring software that alerts you if there are any performance issues.
CW Energy’s high-quality modules come with a 12-year product warranty and a 30-year linear performance warranty. In general, a solar system with CW Energy modules requires minimal maintenance and is designed for long-term reliability.
The time it takes to see a return on your solar investment depends on factors such as system size, your energy consumption, and local electricity rates. On average, homeowners in the U.S. can expect to see a return on investment (ROI) in 5 to 8 years. After that, you’ll enjoy decades of low-cost electricity, and the savings will continue to grow. Additionally, tax incentives and rebates can help shorten the payback period.
Yes, in the U.S., there are several federal, state, and local incentives available for solar panel installation. The Federal Solar Tax Credit (ITC) allows you to deduct a percentage of your solar installation costs from your federal taxes. Many states and local governments also offer rebates, incentives, and grants to help reduce upfront costs. Be sure to check with your installer or local authorities to find out about the specific incentives available in your area.
es, installing solar panels can increase the value of your home. Many homebuyers value energy efficiency and renewable energy solutions, meaning homes with solar panels tend to sell for higher prices compared to similar homes without solar systems. On average, homes with solar systems sell 20% faster and for about 6,8% more than those without.
Solar panels are a key part of creating a more sustainable future. They use the sun’s energy, which is clean and renewable, to power homes and businesses. By switching to solar energy, we can reduce our dependence on harmful fossil fuels, cut down on pollution, and help fight climate change. Solar panels also last a long time and require little maintenance, making them a smart and eco-friendly choice for both the planet and your wallet.
