guaranteed production for solar

What is guaranteed production for solar?

Declining costs and increasing incentives make a solar investment extremely valuable – but the price tag certainly isn’t low. When shopping for solar, also known as a photovoltaic (PV) system, you want to ensure you’ll get your money’s worth. So, it’s important to understand the lifetime of the equipment and its expected energy production. Many solar installers will guarantee a certain amount of electricity production to provide peace of mind when installing a PV system. In this article, we break down solar power production guarantees, what happens when a system’s production doesn’t match the amount of power guaranteed, and why some solar companies don’t offer this for home solar panel systems.

solar panel efficiency

What are the most efficient solar panels? Top brands in 2023

In the past years, solar technology has been making leaps and bounds towards higher solar cell efficiency, power output, and overall quality. Nowadays, solar panels have conversion efficiencies over 20 percent on average, compared to their previous average of less than 15 percent. They also now mostly come with a warranty of 10-25 years, helping you feel more confident in the longevity of your purchase. It is important to know what determines solar panel efficiency before making a purchase so your investment in solar can generate the most energy and ultimately save the most money on your electric bill.

ADT Solar: the complete review

The ADT logo can be found on homes across the United States, broadcasting that they’re protected by the home security system of a trusted and reliable company. Solar probably isn’t the first thing that comes to mind when you think about ADT, but in 2021, they entered the residential solar market with the acquisition of Sunpro Solar, creating ADT Solar. So what does going solar with ADT Solar look like? Let’s dive in.

solar panel output energy production

What is the output of a solar panel?

Most solar panels on the market in 2022 produce between 250 and 400 watts of power. You might come across these solar panel output numbers from your solar installation quote, which will typically include “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.

Sunrun statistics

Key things to know about Sunrun in 2022

In 2007, Sunrun launched in San Francisco, CA with their core business model centered around providing power purchase agreements – meaning they own the panels they install on your roof and sell you the power your panels generate. Today, they’ve shifted their strategy and are currently the largest solar installer in the U.S. with about 13 percent of the residential solar market – a feat they reached in large part due to their acquisition of Vivint Solar in 2020, formerly the second largest installer after Tesla. As the solar industry continues to grow, so does the demand for solar-plus-storage systems and Sunrun has also stepped up to meet this opportunity, now offering these systems in most areas of the country.

Adding solar panels to an existing system: what you need to know

If you’ve gone solar, you’ve already decreased (or possibly eliminated) your electricity bill. But you may want to add more solar panels to your existing system; your solar panel system could be undersized to begin with, or you might have increased your electricity usage since installation due to new additions to your house, new appliances, or adding an electric vehicle (EV) purchase.

Longevity of solar

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.
