How much energy does a solar panel produce? Solar panel output explained

Power output or wattage is an important factor to consider when comparing solar panel options. You may hear your solar installer say, “it’s a 255 Watt panel” or “the panel I am recommending is has a solar panel wattage of 300.” Or, when you are reading a quote from a solar installer, you might see numbers like 245W, 300W, or 345W next to the name of the panel. They are all referring to a solar panel’s wattage, capacity and power output.

Powering through: 2020 NREL study reveals the true longevity of solar

One of the most common statements you’ll hear us say about solar is that it’s a great investment. Among many reasons, we say this because solar panels last a long time. Most solar panel manufacturers now offer warranties between 20 and 25 years, with some going even longer. The average payback period in the US is around eight years, meaning you’ll save substantial amounts of money for well over half of your system’s lifetime. 

But warrantied production is one thing and actual performance is another altogether. So, how well do panels actually perform as they age? A 2020 study by the National Renewable Energy Laboratory (NREL), PV field reliability status—Analysis of 100 000 solar systems, provides some compelling insights.

Flying high: how drones are revolutionizing the solar industry

Ten years ago, if you were installing a rooftop solar system, one of your installer’s first steps was to come to your house, climb up on your roof, and take a bunch of measurements and pictures to evaluate the project. However, this process is now starting to change with the rise of a new technology: drones. Drones in solar have a number of advantages that make them appealing to both homeowners and installers, including saving time and money for everyone involved. In this article, we’ll take a look at how drones are used in solar projects and explore some major companies on the cutting edge of this technology.

Comparing quotes: why are installers proposing different system sizes?

So you have a few quotes, sit down to evaluate them, and notice something right off the bat: installer A and installer B have proposed different sizes for your solar panel system. Why is this? And how can you truly compare apples-to-apples in this scenario?

In this article, we’ll review why this might happen – and what you can do about it!

Should you get a solar operations and maintenance (O&M) package?

For many, solar panel systems are mostly a “set it and forget it” investment, requiring very little maintenance over the 25+ years. However, if you’re looking for extra peace of mind, one upgrade to consider is a solar operations and maintenance (O&M) package. Simply put, O&M packages are essentially protection plans for your solar investment. You can think of them as a sort of “homeowner’s insurance” for your solar panels; if a tree falls on a portion of your house, a home insurance plan will likely cover a large portion of the repair costs –  the same is true of solar energy system repairs under O&M plans.
