Like most technology products that you buy, solar panels come with warranties that help safeguard your investment in the unlikely event that a problem occurs after installation. When evaluating solar panel manufacturers, the two most important warranties 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.
1. What is Solar Panel Product Warranty?
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. Most solar panel manufacturers warrant that their panels will not fail for at least the first 10-12 years, and some extend their warranty periods even longer than that. As with most warranties, a longer period is generally more advantageous to you, if you own your solar panel system. Continue reading
You may hear your solar installer say “it’s a 255 Watt panel” or “the panel I am recommending is a 300 Watt panel” or when you are reading a quote from a solar installer and see numbers like 245W or 300W or 345W next to the name of the panel. They are all referring to a solar panel’s power output.
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, 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.

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.
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. Continue reading
In the past, we’ve written about solar beginning to reach the MLB and the NFL. But since then, more and more professional sports teams are realizing the amazing power of solar energy. In an effort to both reduce their carbon footprint and save money, sports teams across the country are allowing solar power systems to take over their stadiums.
There are so many reasons why going solar is a great idea for anyone from the owner of a large stadium to the owner of a modest residential home. We are optimistic that in the near future every professional sports stadium in the country will be powered by clean, renewable solar energy. Right now, sports fans can follow in the footsteps of their favorite team and go solar themselves! The first step is getting an instant estimate of your property’s solar potential.
Below is a detailed list of the teams and stadiums that have made the switch to solar energy. Continue reading
Solar loans are bridging the gap between purchasing your solar panel system with cash and using a lease or PPA. Like a purchase, a solar loan allows you to own your system and reap the many financial benefits tied to ownership. Like a lease or PPA, it will allow you to go solar with no money down. Today, a host of banks, credit unions and specialty finance companies have emerged presenting a wide range of solar loans. Continue reading

Sustainability is becoming more and more important, not just to organizations whose missions are focused on it, but also to corporations, non-profits, cities and towns that increasingly feel a social responsibility to embrace it in their own operations. All of this is great news, but what’s even better news is that sustainability isn’t just part of how they operate; it’s becoming part of their culture. More and more organizations are looking beyond their own operations to offer their employees, residents, ratepayers or members turn-key solutions for adopting sustainable practices in their homes or businesses. This includes helping them to adopt solar panel systems and other clean and high efficiency energy systems. And, as always, EnergySage is there to help make shopping for solar photovoltaic systems as easy as possible. Continue reading
Our Go Solar Checklist post provided you with useful information to get you ready to start shopping for your own solar power system. We’ve pulled together a short follow-up checklist below that’s aimed at helping you cross the finish line. Here are a few more things to consider: Continue reading
1. Convince / Help Others to Adopt Solar or Other Clean Technologies
Research shows that consumers are 24% more likely to implement clean energy systems and efficiency upgrades after seeing them themselves, but schedules being what they are, visiting in person isn’t always possible. Your EnergySage case study, however, is available for review 24 / 7 / 365 allowing people to access valuable data about your real-life experiences living with these systems. Continue reading
Now that you know more about SRECs, you’re aware of the significant benefits they can provide. So, right about now, you may be thinking, if a normal size system generates hundreds of dollars a year from SRECS, why not install a much bigger system that could increase that number by a multiple of 10? It seems like the perfect plan. Continue reading
