Solar energy and its cost

If one of your New Year’s resolutions is to save money on your electricity bills and/or lead a more green life, you might consider switching to a renewable energy such as emission-free solar power.
According to the Solar Energy Industry Association, in the next two years the amount of solar power used in the United States is expected to double, with more than 16 states expected to have more than 100MW installed in 2016.

But smart consumers don’t just sign up with the first solar company to knock on their front door. Just as you’d do some research before buying a computer or a new car, you’ll want to do your homework before deciding which solar power system is right for your home or business.

SunPower has been a leading solar technology innovator for more than 30 years, so we like to think we know a few things about harnessing the sun to power our world.

We’ve compiled a short guide to our most popular “How to Go Solar” content to help answer some of the most common questions we get asked about our solar panels.

What is Solar Energy?

Solar 101: How Do Solar Panels Work?

This post explains the amazing science behind solar energy, such as how photons from the sun are captured by silicon cells in a solar panel and converted into electricity. When photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, it forms an electrical circuit. When electrons flow through such a circuit, voila, you have electricity.

Cost of Going Solar

How Much Do Solar Panels Cost?

While we often get asked, “How much will a 3kw system cost,” for example, it’s important to understand that you’re not just buying solar panels off a shelf. SunPower will actually custom design your very own solar power system. The cost of your solar power system depends on several factors, including how much sun your rooftop receives, how much power you use and the roof size. This article will help you determine the cost of going solar and how much money it could save you over time.

How Many Solar Panels Do I Need?

The cost of your solar system — and your question: Are solar panels worth it? — depends on the number of panels you need to generate enough electricity to serve your demand. This post explains in four steps how to answer this question. To calculate how many solar panels you need, you must determine how much energy your household uses; your roof’s usable surface area; the climate and peak sunlight in your area; the wattage and relative efficiency of the photovoltaic (PV) technology of your panels; and whether net metering is available. If this sounds daunting, don’t worry. A SunPower® solar advisor can give you a free evaluation to help you figure out if solar is right for your home or business.

How to Install Solar Panels

Choosing a Home Solar Installation Company
Ready to go solar? This post outlines six tips for finding an expert to install your solar panels. It outlines questions to ask about solar panel installation, such as which products the installer uses, whether a warranty is offered and what it covers, payment options and what are the local utility rules for solar power.

Solar Panel Installation in Seven Steps

Once you’ve signed your solar contract, this graphic explains in very simple and visual terms the seven steps to installing a home solar system so you’ll know what to expect along the way.

Solar Power Pros & Cons

Having some healthy skeptism about a major household improvement project such as going solar makes sense. Afterall, you’re investing in a technology with a useful life of 40 years! This video, and a more in-depth blog post, take a look at four pros and cons of going solar and debunks some common myths.

Solar DAO is a closed-end investment fund created on the basis of blockchain technology to finance construction of PV solar plants around the world.

Thanks to Solar DAO, investors with modest budgets will be able to enter the industry and participate in construction, management and capacity expansion of PV solar plants. At moment, Solar DAO is in the middle of its Pre-ICO for tokens that closes on August 31st. Tokens will grant access to the project’s 100% profit through dividends distribution.

As different from many other ambitious startups, Solar DAO business model is firmly rooted in the real economy. The project is about building and managing PV solar plants globally, while continuously expanding their capacity. But how exactly do PV solar pants work? This article will explain.

Generating Energy from the Sun: Photovoltaics
George Porter, the winner of the Nobel Prize of 1967 in chemistry, once said:

I have no doubt that we will be successful in harnessing the sun’s energy. If sunbeams were weapons of war, we would have had solar energy centuries ago

Thankfully, we now live in the age when solar energy is used efficiently, sustainably, and peacefully. The key technology that allows us to use the sun’s energy is solar photovoltaics.

Solar photovoltaics is used to convert sunlight into electricity. Solar photovoltaic cells are made of semiconductor materials (for example, silicon). When exposed to sunlight, the semiconducting material causes electrons in the materials’ atoms to be knocked loose. The electrons that are knocked loose then flow through the material to produce an electric current known as a direct current (DC).

In short, the light separates electrons from atoms to create an electric current.The following picture illustrates the process schematically. Red wavy arrows on the picture represent sunlight, and encircled minuses stand for electrons — negatively charged particles. Red arrows symbolize the direct electric current.
