Longevity of solar

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

Reading Time: 5 minutes

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.

cost of solar equipment declining over time

How have solar equipment costs declined over time?

Reading Time: 3 minutes

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.

Solar roadways: what you need to know

Reading Time: 5 minutes

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.
