Tim Cherry has been thinking about going solar for a long time. For the past forty years he’s been contemplating putting panels on the buildings on his 75 acre farm near Nacogdoches, Texas. But Tim wasn’t able to find an installer that he felt comfortable with, and he wasn’t sure about the price, until he got the information he needed on the EnergySage Marketplace. Continue reading
What is a solar panel warranty?
A solar panel has two warranties: a performance and equipment guarantee. A solar panel’s performance warranty will typically guarantee 90% production at 10 years and 80% at 25 years. An equipment warranty will typically guarantee 10-12 years without failing. SunPower offers the best warranties.
A solar panel’s product warranty covers the integrity of the panel itself, and protects you against failures due to manufacturing defects, environmental issues, premature wear and tear, etc. As with most warranties, a longer period is generally more advantageous to you, if you own your solar panel system. When evaluating a solar panel warranty and its manufacturer, the two most important factors on which you should focus are:
1. Product (or materials) warranty, and
2. The performance warranty
We’ll address both of these in this article as we break down our process for finding the best solar warranties offered by manufacturers.
Solar adoption is skyrocketing in the United States. Partly responsible for this surging uptake is one of the oldest industry drivers: word of mouth marketing. The SolarCity Ambassador Program, EnergySage Rewards Program, and others are a big part of this growth. Continue reading
Power output or wattage is an important factor to consider when comparing solar panel options. You may hear your solar installer say, “it’s a 255 Watt panel” or “the panel I am recommending is a 300 wattage.” Or, when you are reading a quote from a solar installer, you might see numbers like 245W, 300W, or 345W next to the name of the panel. They are all referring to a solar panel’s wattage, capacity and power output. So, what is the typical output of solar panels?
This piece will explain how solar panel ratings work so you can better compare your solar options. All solar panels are rated by the amount of DC (direct current) power they produce under standard test conditions. Solar panel power output is expressed in units of watts (W), and represents the panel’s theoretical power production under ideal sunlight and temperature conditions. Most solar panels on the market today have power output ratings ranging from 200 to 350 watts, with higher power ratings generally viewed as being more favorable than lower power ratings. Pricing in solar is typically measured in dollars per watt ($/w), and the wattage of your solar panels plays a significant part in the overall cost of your solar system.
People say all the time that they want to get off the grid. Beyond just meaning getting away from it all for a while, getting of the grid has a specific technical meaning with regards to your relationship to your utility and how you get your power. So, what exactly does it mean to go off the grid? Continue reading
