The cost varies based on the technology being used, and on where it is being installed. The reasons for those differences are fairly easy to figure out, but sunlit geography is only the beginning, says Seth Darling, a scientist at the U.
Figuring out the levelized cost requires a number of guesses: How well the solar energy system will perform, how long it will last, and even how much sunshine it will get over the next 30 years. The U. And that analysis looks at large-scale solar, the kind usually owned by utility companies.
GRU helped Gainesville residents get around that problem by implementing a feed-in tariff, a system where a utility offers solar panel owners a year contract to buy solar electricity, guaranteeing the owners will make a set profit on their decision to go solar.
Converting light into electricity with no moving parts is a profoundly different enterprise than turning a turbine to make power—the technology that is at work in coal, natural gas, nuclear, hydropower plants and, most visibly to the public, at wind farms.
It just needs to be improved. Most solar cells are made from silicon—the same semiconductor material that is at the heart of computers. The cells are expensive to produce because it takes a great deal of energy to purify the silicon. Their advancements have been about how to design and fabricate that intricate structure cheaply.
It changes the economics dramatically since the manufacturing cost is more closely tied to the cost of the material, not the patterning. What may really help to lower the cost of solar are new materials—especially semiconductors made from the compound cadmium telluride.
In fact, Ryne Raffaelle, director of the National Center for Photovoltaics at the National Renewable Energy Laboratory, says the solar array itself accounts for only half the cost of a solar system today.
For one thing, not every great idea that works in a lab can be replicated on a mass production scale. And it can take a long time to iron out technological kinks on an apparatus that the manufacturer wants to be sure will last a long time.
Consumer electronics is relatively quick. You want it to work and be durable. And that means you have to spend a long time testing it.
That works because electricity is already expensive in those places, and because locations are ideal for producing solar electricity—lots of clear, sunny days. Friley offers another option. Even in places where the average cost of electricity is low, that cost varies with the seasons and the time of day. Peak load times happen to coincide with the peak hours for sunshine.
If the system were designed to encourage the use of solar to cover peak load, the cost savings would be substantial, he says. Solar would naturally reach grid parity faster under policies that accounted for those costs by putting a tax or price on carbon. In fact, the right answer could change over time. So materials costs are a large part of the price, but typically they make up less than half the total cost of a solar installation. That astonished me since I guessed it would be much more.
It turns out that more than half of the cost of a home solar system is made up of installer fees and margins and expenses relating to having the system inspected and obtaining the relevant permits. This means that if we can find a way to reduce installation costs, then we can make substantial savings on our solar systems. The softest part of your solar system cost relates to the installation and other contractor expenses, and here are some steps you can take to reduce these and make your solar system less expensive.
Instead, you should look at several contractors operating in your area and ask friends for recommendations wherever possible. Traditionally the most expensive providers are the one-stop-shop guys who deal with every aspect of the purchase and installation of your solar system. Sure, this is the most convenient way to do it but you can expect to pay a considerable premium for that convenience. You can save a lot of money by sourcing the solar system hardware yourself and then hiring a contractor for the installation only.
Sure, you want to get everything right, so this is only a step you should take if you are confident in your abilities, but be aware that it will make a massive reduction in the cost of your system.
Thankfully there is a straightforward proces s you can use to find out how much energy will need to power your home by solar. Perform this exercise and ensure that you get quotes for a system that is big enough but not too big. She is working on installing solar panels statewide for free, as per NBC The cost of solar panels ranges, depending on how much energy your home consumes. This sounds pricey, but solar panels are much cheaper than they used to be.
The Solar Energy Industries Association SEIA claims the average price for solar panel installation has dropped by about 70 percent since , and by about 37 percent in the last 5 years. Unfortunately, the high upfront costs of solar panels often deter people who simply want to live a greener lifestyle. As per a report from Unbound Solar , major solar panel installation companies sometimes double or even triple the cost of the equipment itself by giving homeowners the convenience of covering installation.
That said, it's recommended you hire a small contractor , or do it yourself. Solar panels themselves, however, are relatively costly, due to the high quality materials they're made from.
