How many peak sun hours do solar panels need?

If you're considering purchasing solar panels for your home, you are probably wondering whether or not you receive enough sunlight where you live. You may have also heard that it's not just the total amount of sunlight, but the 'peak sun hours' you get that is a key criterion. In this blog, we explain what this term means, and how the number of sun hours varies from place to place. Even though solar panels produce electricity during all hours of the day, they work best when the sun’s rays shine directly on them.

5 Reasons Why Going Solar is the Right Choice in 2020

Article | March 3, 2020

If you’ve been considering adding solar energy to your home, 2020 is the perfect time to do so. Last year, solar owners were able to receive maximum benefits from the federal solar investment tax credit (ITC), which gives homeowners an opportunity to receive a tax credit towards income taxes after their solar system is fully installed and operating. While 2019 was the last year to get the full 30% federal solar tax credit, there are still many great reasons to add solar to your home in 2020.

The Key to Unlocking 100% Renewables

Article | February 27, 2020

The 100 percent renewable energy future doesn’t start with a country, state or region. It starts with a city. One power plant in a city, in fact. In Glendale, California. Glendale is a city of 200,000 people just north of Los Angeles. And in 2014, Glendale was in a tricky spot. The city’s natural-gas plant was old. The City Council faced a decision that would impact the municipality for decades to come: revamp the 252-megawatt gas plant or find local alternatives?

Recognizing and solving challenges in renewable energy land usage

Article | February 14, 2020

As anyone familiar with the saga of the Spotsylvania solar project knows, an inherent difficulty in developing renewable energy projects comes in finding the right project location, both in terms of size and siting. This is one of the topics analyzed in a new report released by The Brookings Institute: “Renewables, land use, and local opposition in the United States.” It’s a hard fact that renewable generation uses more land than fossil fuel systems, with solar having slightly lower median land use than both on- and offshore-wind, despite a large variance in total land density values. While this presents an issue for renewable developers, the silver lining is that renewable energy can be sustained indefinitely on the same land base, while mines and wells will eventually run out. As a solution, the study recommends greater development on brownfields, as well as floating PV, though the authors do recognize the capped potential of floating PV at around 10% of current U.S. electricity generation.

How Artificial Intelligence is changing the Energy Sector

Article | April 9, 2020

Artificial Intelligence, or AI, has gained relevance in many different fields of our life, using machine learning to analyse historical and new data in order to make predictions, improve control operation and perform tasks much faster than a human and with more efficiency. The energy sector is using AI to increase energy efficiency by reducing consumption, improving energy storage and grid stability, making predictions about energy consumption, to have more accuracy to find oil & gas and many other applications. When it comes to renewable sources, AI is improving the weather forecasts for the development of new plants and to make better planning of control & maintenance. Let’s take a look in some projects and how they are affecting the energy sector.
