Do you know which solar companies are making the most money around the world? This visualization examines the annual revenue data for some of the top solar companies.
Solar panel efficiency has grown quite a bit since the very first solar cells were created back in the 1880s. Back then, the solar cell efficiency was incredibly low, less than 1%, and today, scientists are creating high-efficiency solar panels that can reach almost 50% efficiency!
The history of solar-powered cars began as a humble 15-inch solar-powered car model made of balsa wood in 1955. Along the way, many marvelous innovations have emerged.
If you’ve been thinking about making the switch to solar, check out this comprehensive solar panel size chart that sheds light on the average size of solar panels, how many cells solar panels have, and how much solar panels weigh.
When considering solar energy for your home, the solar panel installation cost is a significant factor in the decision-making process. This quick-reference guide will give you a better idea of the average cost of solar panels based on your location. Depending on the size of your home and your location, and after taking tax credits into account, the solar installation cost can be anywhere between $17,000 and $40,000.
Did you know that if you’ve recently upgraded your home or business to be powered by solar, you may be eligible for a solar tax credit? The federal solar tax credit is an incentive program offered by the federal government to encourage Americans to install and use solar power to provide energy for their homes. Solar power has many benefits, such as reducing the need for fossil fuels and coal, but the installation of solar power equipment can be expensive.
How often do you clean your solar panels? Most people don’t clean theirs as often as they should, and a dirty solar panel can have a big impact on the amount of energy generated to power your home or equipment. If you live in a drier climate that doesn’t receive much rain, solar panel cleaning is even more crucial as there will be much more dust buildup on the panels with nothing to naturally clean them.
The solar panel lifespan is 20-30 years, according to the Solar Energy Industries Association. Which means that solar panels installed in the 1980’s and 90’s could still be in use today. Several factors affect the life expectancy of solar panels, including climate, maintenance, the type of solar panel, and the way it was installed.
