If you’ve shopped for solar before, you may have come across something known as “Sun Number” or sun score. Like EnergySage, Sun Number received funding from the Department of Energy’s SunShot initiative to innovate in the solar energy space. Read on to learn more about how a property’s Sun Number is calculated and what your sun score means for going solar.Continue reading

What will a 10,000 Watt (10 kW) solar system cost in your state?
10kW solar systems are among the most popular solar energy system sizes in the country, producing enough electricity to power a home with slightly above-average electricity consumption. How much does a 10kW solar system cost? How much electricity will a 10kW solar system produce? How do you know you’re getting the best deal on a system? These are some of the key questions we will answer in this article.Continue reading
How much does a 6,000 watt (6kW) solar system cost?
If you’ve been looking into going solar, you’ve probably at some point seen quotes for a 6kW solar system. 6kW solar systems are one of the most popular system sizes in the US because in most places they will produce about the right amount of electricity to meet an average household’s daily electrical needs.Continue reading
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.Continue reading
How have solar equipment costs declined over time?
Over the last decade, the costs of solar have decreased from over $8 per Watt in 2009 ($/W) to $2.75/W in 2019 on EnergySage, a decline of more than 65 percent in 11 years. Over this timeframe, a primary driver of the declining cost of solar in the US has been technological improvements in the actual hardware that’s included in solar energy systems: solar panels and solar inverters.Continue reading
Economic benefits of renewable energy
As renewable energy becomes more widely adopted throughout the United States, it is worth pausing to take stock of the economic benefits associated with increased levels of solar, wind and other renewable energy resources. From providing lower cost electricity to generating reliable, local jobs and to avoiding costly externalities associated with emissions from burning fossil fuels, renewable energy is an economic boon.Continue reading
How to decide if high-efficiency panels are worth the cost
High-efficiency solar panels are becoming increasingly popular, and can impact how much solar power you can produce on your roof or property. Given all of the options for high-efficiency products, though, it can be hard to get a feel for how the efficiency of your panels influences the costs you pay for solar. Here’s a quick guide to help you determine if high-efficiency solar panels are worth the added cost when comparing your solar options.Continue reading
CEO’s note: Why I’m excited about the EnergySage Buyer’s Guide
We are very excited to release a brand-new online tool for the solar industry: the EnergySage Buyer’s Guide – a first of its kind tool to allow consumers to research, compare and evaluate the price and quality of solar panels, inverters and batteries. To introduce you to our new product, I would like to give you some context for why we built the Buyer’s Guide and describe how we anticipate solar shoppers and industry stakeholders alike to use it.Continue reading
Solar roadways: what you need to know
Innovation in the solar energy industry is happening constantly. While panels are typically installed on rooftops or on large plots of land, some in the industry think that roads and highways are a suitable place for solar panels as well. Solar roadways are roads that have integrated solar cells generating power from the sun – in this article, we’ll examine how feasible solar roadways are and what their future might look like.Continue reading
How long does it take to install solar panels?
If you’re considering installing solar panels, one of your top questions may be how long it will take after signing a contract to finish your solar project. There are a number of factors that determine this timeline – in this article, we’ll discuss those factors, as well as the average estimated timeframes for a solar panel installation from start to finish.Continue reading
