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.

The process 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. Solar system design takes into account 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 depending on your property Continue reading
As people begin the process of researching a potential solar PV system, one of the first questions they ask is “Is my roof even suitable for solar panels?” Solar panels are compatible with most roofing materials, but some are better for solar than others. Read on for EnergySage’s complete guide to determining whether your roof is good for solar.
When shopping for airline tickets or other big-ticket items, people generally shop around. For airline tickets you might compare: How much will it cost? When are the flights? What are the baggage charges? What’s the airline’s safety record? What’s their “on-time” percentage? How much leg-room will there be? Etc. People use a comparison shopping approach because it gives them all the information needed to make the right choice. The same is true when shopping for solar power systems for your home or business. If you take the first offer that comes your way, how will you ever know if you got the right system or the best price or terms for your property? Continue reading
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.
Solar panels don’t just power your AC on blisteringly hot summer days – they also take over some of the AC’s work themselves. This is according to a study from researchers at the University of California at San Diego, which says that rooftop solar panels not only produce emissions-free electricity, but also cool roofs and buildings to which they are attached. This lowers cooling costs, and offers an additional benefit of going solar. Continue reading
Of all the incentives for installing solar panel systems, solar renewable energy certificates (SRECs) are some of the most potent, yet least-understood. You may have heard enigmatic terms like “SREC markets,” “solar renewable portfolio standards,” and “minimum compliance payments” thrown around in discussions about SRECS, but sifting through of all this jargon can be downright mind-numbing. However, SRECs can provide sizable streams of money to owners of solar power systems, so learning about what SRECs are, where they are available, and how they can make solar more financially-rewarding can, quite literally, pay off in a big way. In this article we aim to answer the simple questions: “how do SRECs work?”
One of the most critical components to a successful solar panel system installation is, of course, choosing the right solar installer. No matter if you are in Massachusetts, New York or California, a knowledgeable and competent installer is key to achieving your financial goals. This is true not just in terms of what you will pay to install your system, but also in terms of maximizing your system’s economic benefits by installing an appropriately sized system, maximizing production levels, taking advantage of incentive and rebate programs, etc. So what should a property owner look for in an installer? Here are some of the criteria that EnergySage uses when choosing installers for our own network of pre-screened high-quality installers: Continue reading
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
