Solar panels are an increasingly popular way to power one’s home or business. They are environmentally friendly and can lead to energy cost savings. But how much energy do they produce? The answer varies, depending on the brand and size. Read on to learn more about solar energy production and which brands are best for Las Vegas homeowners.
How Much Energy Does The Average Las Vegas Home Use?
According to Energy Sage, the average electricity user in Las Vegas uses 1,244 kilowatt hours (kWh) of energy per month, and nearly 15,000 kWh in a year. This costs the average annually well over $2,000 a year in electric costs. No wonder so many people are considering the switch to greener energy.
Understanding “Watt” It’s All About
Solar panels are rated by how many watts they can produce in an hour. For example, a system with a rating of 200 watts can generate a maximum of 200 watts of power in an hour. In 2022, rooftop solar panels for homeowners will have power output ratings of anywhere from 250-450 watts. The more panels you install on your roof, and the higher their output capacity, the more power you’ll be able to generate.
Three Factors That Affect Energy Production
The number of kilowatt hours that a complete system can produce depends on three main factors. Next, we’ll look at each of these in turn.
- The System’s Overall Efficiency
- The Amount Of Sunlight Received
- The Angle At Which The Sun Hits Them
Solar Panel Efficiency In A Nutshell
The percentage of sunlight measures panel efficiency converted into electricity. The average solar panel only has an efficiency of between 15% and 20%. This means that for every 100 watts of sunlight received, only 15-20 watts of electricity are generated. Climatebiz.com, “On average, a 250 W solar panel can produce approximately 1 kWh of energy per day (considering four peak sun hours and 80% efficiency).”
It’s Called Solar Energy For A Reason
The sunnier it is, the more power your solar system will produce. Even a slight increase in sunlight can result in a much more significant increase in power output. That’s why installing panels in sunny locations, preferably south-facing, is so important.
How Angles Affect Solar Power Production
Because the sun moves across the sky during the day, the panel’s angle relative to the sun changes as the day continues. When it’s perpendicular to the sun’s rays, it will receive more sunlight and produce more energy. However, if it’s at a low angle, it will receive less sunlight and create less energy. Therefore, to maximize output, it’s best to position panels parallel to the sun’s rays at midday, when the sun is highest in the sky.
What Are The Best Solar Systems On The Market?
Now that you have a better grasp of the technical details, you’re probably wondering which systems are best. In our opinion, two brands outrank others in terms of superior energy production.
These two names are the ones you’re most likely to see in the news. Many installers and alternative energy providers depend on brands like Tesla and Sunpower for their system installations.
Powerful Tesla Systems Are Great For Las Vegas
As of 2022, Tesla panels can produce between 400-425 watts each, with a higher-than-average efficiency of nearly 20%. As a result, many homeowners have found that they can power their entire home by installing an array of rooftop Tesla panels coupled with one or more Powerwalls.
Sunpower Also Offers Superior Systems
As of 2022, a single Sunpower rooftop solar panel can generate up to 415 watts. They are among the most efficient solar panels on the market, with a conversion efficiency of up to 21%. This means they can convert more of the sun’s energy into electricity than other solar panels. As a result, a Sunpower solar system may also generate enough electricity to power a typical Las Vegas home, with fewer panels than many other brands require.
