Home solar is more popular than ever, and if you’re in the market for a new home, you might come across options with solar panels already installed. It is important to understand the unique aspects of buying a solar-equipped home so you can enjoy the benefits of solar energy without having to go through the installation process.
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 has a wattage of 300.” 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.
How much energy can a solar panel produce?
Available sunlight will vary depending on where you live but for the sake of an example, if you are getting 5 hours of direct sunlight in a sunny state like California you can calculate it this way: 5 hours x 290 watts (a wattage of a premium solar panel) = 1,450 watts or roughly 1.5 kilowatt-hours (kwh). Thus each solar panel in your system would produce a little over 500-550 kWh of energy per year.
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 home solar panels on the market today have power output ratings ranging from 250 to 400 watts, with higher power ratings generally considered preferable to lower power ratings. Pricing in solar is typically measured in dollars per watt ($/W), and the total wattage of your solar panels plays a significant part in the overall cost of your solar system.
Are you considering a solar energy system for your home or business in New York, but want to know more about the costs and benefits before making a decision? In this article we look at the reasons why going solar is a good idea in New York, and also examine the various incentives and financing options that may be available to you if you are a New York resident.
Every solar company has a variation of the same sales pitch, “did you know going solar can save thousands of dollars?” They make it sound so easy, but the truth is, whether solar is a smart long-term investment for you depends on a few major factors. So before you buy into the hype, we recommend you use this simple guide to cut through the sales jargon and determine if solar panels are actually worth the money.
If you’ve been looking into going solar, you’ve probably at some point seen quotes for a 6kW solar system. 6kW solar systems are one of the most popular system sizes in the US because in most places they will produce about the right amount of electricity to meet an average household’s daily electrical needs.
Solar leases & PPAs have made going solar accessible for virtually anyone with a roof, but what if you’re thinking about purchasing a system? Since you’ll probably be spending your own money, you’ll want to be extra selective about the installer who does the job and the components that are used.
This article investigates these questions: 1) How much does a 6kW solar system cost, 2) how much electricity will a 6kW system produce, and 3) how do you know you’re getting the best deal? Continue reading
If you’ve been shopping around for a solar panel system, you’ve probably heard at least one company advertise ‘free solar panels’ – that they will install a solar system on your roof for free. But, much as with anything, remember that there is no such thing as a free lunch (or a free solar panel).
Decoding the sales pitch: The term ‘free solar panels’ is sometimes used to advertise solar lease or solar power purchase agreements (PPAs).
Under both types of arrangements, a company will put solar panels on your roof for no money up-front, but will charge you for the electricity that they produce.
The number of properties with rooftop solar panels is increasing day by day, and it isn’t just homeowners who are installing solar panels to offset their own electricity bill. Businesses as small as your local general store and as large as Google have installed solar on-site to decrease overhead costs and promote corporate social responsibility. Now, nonprofit organizations are starting to explore their solar options as well.
Installing solar at your home or business has significant financial benefits. In many cases, you can choose a zero down solar financing option and install your system without paying any money up front, leading to instant savings. In this article, we will examine the various options for $0 down solar and the merit of each option.
As the cost of solar continues to fall and the financial and environmental benefits of solar PV grow, more organizations are collaborating to provide reasonably priced solar options to homeowners. For example, National Grid recently announced that it is partnering with EnergySage to offer a solar marketplace option to its Rhode Island customers. Recently, Comcast also announced a partnership: the cable company will offer a discounted solar option to its customers through an exclusive partnership with Sunrun. Find out more about what the Comcast solar offer means for you.
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.
