There are a lot of factors that can affect the performance of your solar panels and the economic benefits they can generate—things such as where you live and how sunny it is, how much you pay for electricity, which way your house faces—even the pitch of your roof. Variety is the spice of life, but the diversity of our architecture can affect the performance of solar panels. It’s important to understand how those differences in production performance related to the angle of your roof will affect the overall financial performance of your solar power system.

Choosing the right solar panels is one of the most important steps in designing your solar power system. There are hundreds of options, and while all panels are designed for one purpose – to convert sunlight directly into electricity, not all panels are created equal. Different solar cell technologies and the quality of manufacturing can impact the performance of your panels. For these reasons, comparing solar panels and finding the right one to meet your specific system needs can sometimes be a complicated task; but, it doesn’t need to be.
In this article we’ll explain important metrics like PTC power rating, STC, degradation rate, efficiency and temperature coefficient.
You don’t need optimal conditions for your solar power system to be a great investment. One of the biggest myths about the financial viability of solar is that it requires a really sunny location and a south facing roof. While these may be ideal conditions, folks outside of Southern California with roofs that face other points on the compass, such as east to west-facing roofs, can still satisfy most of their electricity needs and reap significant financial returns when they adopt solar power systems.
Although many commentators, bloggers, and armchair pundits argue that solar power is only cost-effective in sunny locations, the fact is that just isn’t true. While the argument that more sun means more electricity means more savings may seem tenable at first, it isn’t consistent with what’s happening in today’s solar market. New Jersey certainly isn’t mounting a strong challenge to become the new “Sunshine State,” and yet, it’s installed more solar than any other state in the U.S. On the global stage, high-latitude Germany is the clear leader in solar installations. An endless summer is no longer a requirement for solar power success. Continue reading
When shopping for solar photovoltaic (also known as solar panel, solar electric) systems, many businesses and homeowners focus mainly on price. To that end, dollars per watt is a key metric when comparing quotes because it allows the consumer to adjust for differences in system size. While price is certainly an important factor, maximizing the value of your investment both financially and environmentally, involves consideration of several other, equally important factors. Here are some that we think are vital to making the right decision about your solar panel system. Continue reading
