Not all solar panels are created equal. EnergySage uses a classification system for solar panels based on performance, quality, durability and warranty to help solar shoppers compare the quality of all of their options. A solar panel’s efficiency (how effective a panel is at converting sunlight into electricity) is a key factor determining solar panel quality, and manufacturers are constantly improving their processes to create higher-efficiency solar panels.
For those looking for the most efficient solar panels for their PV system, the first thing you need to know is how to compare efficiency metrics for different manufacturer brands. Simply put, efficiency (expressed as a percentage) quantifies a solar panel’s ability to convert sunlight into electricity. Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings, the more efficient panel will produce more electricity than the less efficient panel.
As the race for the most efficient solar panel continues, it’s important to understand how more efficient panels could mean much bigger solar savings for the everyday consumer.
In practical terms, for two solar panels of the same physical size, if one has a 21% efficiency rating and the other has a 14% efficiency rating, the 21% efficient panel will produce 50% more kilowatt hours (kWh) of electricity under the same conditions as the 14% efficient panel. Thus, maximizing energy use and bill savings is heavily reliant on top tier solar panel energy efficiency.
The process of of how solar installers design a solar energy system is often a mystery for most consumers. Because of this, we would like to give you some insight into how solar installers design a solar power system for your home or business. A solar power system is designed considering two important factors – the amount of space that you have available for installing solar panels and the amount of electricity you consume annually. Other factors, like shading analysis and the efficiency of solar panels and inverters also come into play. Continue reading →
Tesla recently announced pricing for their new solar roof product, a roof replacement for your home. The new solution requires that you replace your existing roof with Tesla’s blend of non-solar glass tiles and solar-enabled glass tiles. It is an elegant new product, designed with great aesthetics. But the question is ultimately does installing this new roof make financial sense for your home? After initial analysis, we’ve found that for the majority of homeowners the answer is currently “no”. Just as Tesla’s luxury sports cars are out of reach for most drivers today, Tesla’s new solar roof is simply too expensive for most American homeowners to justify spending their money on.
If you’ve found it difficult to stay up to date on the future of Tesla Motors and SolarCity in recent months, you are not alone. Numerous industries (solar, electric vehicles, and ridesharing, to name a few) worldwide are starting to feel the impact of a merger that could significantly alter growth plans for manufacturers and executives across the globe. Now the concept of an integrated solar glass shingle – the Tesla solar tile – is on everyone’s mind.
We had already heard about Tesla’s plans for total clean energy integration – a one step carbon reduction process that involves pairing solar panels with your Tesla electric vehicle. Now for the latest: thanks to a surprise appearance of Chairman Elon Musk in SolarCity’s 2nd quarter earnings call that lead to a highly anticipated Tesla solar roofing product launch at the end of October, we’ve now seen the future of PV roofing and the future of Tesla. One thing is certain: building integrated photovoltaics (BIPV) are going to be a part of Tesla Motors – or should we say Tesla Energy’s – future.
For those asking themselves, “should I wait for the Tesla solar roof?”, you are not alone. Elon Musk, co-founder and CEO of Tesla Motors, has a well-earned reputation for creating innovative 21st-century products that combine attractive designs with exceptional performance – and generate high levels of consumer interest as a result. The latest Musk technology to make a splash is the Tesla solar roof, which he revealed to great fanfare in October 2016. Here’s everything you should consider before making your decision, including what Tesla roof rivals you should consider.
REC Group is Europe’s largest manufacturer of solar panels, and has offices in Europe, the United States, Asia, and Australia. The company was founded in Norway in 1996 and manufactures its solar panels in Singapore. REC Solar panels are an increasingly popular option in quotes to shoppers comparing solar offers on the EnergySage Solar Marketplace.
If the sun isn’t shining on your solar panels, they won’t be able to produce energy. When trees or other obstructions are shading solar panels, efficiency losses and reduced power generation may become problematic. In this article we will examine the effects of shade on solar panel production and efficiency.
Solar panels are often exposed to high amounts of heat, especially during long, hot summer days. In this article, we will discuss the impact hot weather has on solar panels, and how those effects are mitigated by consumers and manufacturers alike.
Like any outdoor equipment, solar panels are subject to the changing weather. Depending upon where you live, your panels may experience heavy rain, high winds, or even hail. In this article we’ll examine how solar panel systems stand up to intense weather conditions, and what government organizations and industry groups are doing to improve their products and protect consumers from weather-related solar panel damage.
