Where Can I Buy Sunpower Solar Panels

What Other Components And Equipment I Need For A Fully Functional Solar System

Are SunPower Solar Panels Worth It? (2019)
  • Solar Inverter

The inverter has one specific purpose to safely switch the DC energy from the solar panels to AC energy, which can be used inside the home. Without a solar inverter, you wont be able to utilize the energy for your appliances or lights. Since the solar inverter is the heart of every solar system its logical that you want to invest in a quality inverter given its critical place in the equation. You can find out more about solar inverters here.

  • Solar Batteries

Batteries are an optional components. There are people who use solar power on demand, which means they only use solar energy when the sun is shining. But it also means they dont have solar power during the night. For the most part, when people install a solar array, they take the battery option as well. Provided that you probably spend most of your day at work and use most energy at night, batteries just makes sense. Naturally, you get different sizes, models, and quality options from world leading manufacturers.

  • Solar Charge Controller/MPPT

Just like the batteries, a solar charge controller is an optional component. It regulates the current used to charge the battery which comes from the inverter. However, a solar charger does become a necessity if you are using panels with high outputs. If you want to maintain the health of your battery and the overall efficiency of the solar array.

Should You Get Sunpower Solar Panels For Your Home

There are three types of homeowners who should get SunPower solar panels:

  • People with limited roofing space: SunPower panels have high power and efficiency ratings, so you can install fewer panels but still produce a lot of electricity.
  • People who like having high-tech products: SunPower truly does make some of the best solar panels out there, in terms of specifications and performance metrics. If you always want to have the latest and greatest, then SunPowers your brand.
  • People who are really concerned about their warranty: SunPower offers a great warranty that covers the entirety of a solar system’s lifespan, and because SunPower is a reputable brand, they should be around long enough to honor that warranty should anything happen in 5, 10, or 25 years.

If you dont fall into any of these categories, then maybe consider another brand of solar panels.

Ask About Solar Panel Financing Options

Many solar companies encourage buyers to use their solar financing packages since income from the financing is an important part of their business model. You wont always be required to do that, but just be aware that you have a choice when it comes to solar financing. Some homeowners prefer to pay cash or take advantage of the popular low-interest/zero-down loans. So find out whether this as an option offered by your solar installer.

Smaller regional solar installers are typically more flexible when it comes to financing a home solar system. While many SunPower dealers have access to SunPower Financing, their main business is installation, not financing. If youd prefer a straight home equity loan through your bank, thats fine with our dealers.

In summary, there are many solar companies to choose from. If you are looking for a customized system design with high-performing and durable solar panels, installed by a local business in your community, look no further than SunPower.

How Do You Determine The Temperature Coefficient

Higher or lower cell temperatures will either reduce or increase the power output by a specific amount for every degree above or below 25°Cthis is called the power temperature coefficient, measured in percentage per °C. How does this work? Lets say your panels have a temperature coefficient of -0.30 and an overall efficiency of 20%. At 30°C, your panels would only operate at an efficiency of about 18.5%a power loss of about 1.5%.

Best Sunpower Solar Panels You Can Buy

SunPower has walked a long road since its inception in 1985 to become synonymous with high-quality solar panels.

While the company does provide several top-tier solar products, its safe to say that its panels are what consumers are really after.

SunPower has an array of solar panels made from highly efficient solar cells produced by Maxeon.

Now, knowing a brand is excellent is one thing, but navigating your way through the mountain of product information is another.

Not to worry, though thats what were here for!

In this article, we help navigate you through the 5 best SunPower solar panels you can buy!


Overview Of The Sunpower Solar Panel Warranty

SunPower not only offers superior efficiency, but also some of the best warranty terms in the industry. The brand gives you a 25-year warranty that covers both defective products and loss of performance over time. In case you purchase your entire PV system from SunPower, the warranty will also cover labor and other components.

  • The performance warranty from SunPower offers you 92% DC output after 25 years, which means their solar panels remain productive for a very long time.
  • For comparison, some low-end solar panels are only rated for 80% performance after 25 years of use.
  • Even if their power output warranty has the same duration, the electricity delivered over time is much less, and this also means your power bill savings are reduced.

Having a reliable warranty with a long coverage period is very important when purchasing solar panels, since it protects your investment.

Many homeowners decide to install solar panels due to the savings achieved over time, and a warranty ensures these savings will reach your pocket. On the other hand, a low-quality solar system without warranties may fail in just a few years or months before you can recover your investment.

Even if a solar manufacturer offers a warranty with excellent conditions, be aware that an unprofessional installation may void that warranty. SunPower offers you the option of purchasing the entire solar system, not only the panels, which means you can combine all component warranties.

How Does Panel Cost Affect Total Installation Costs

Believe it or not, solar panels are only a small portion of the total installation cost. According to the NREL report linked to above, panels typically only account for 22% of the total install cost. Other equipment makes up a further 20%, installation costs account for 10%, and a whopping 36% goes to sales, marketing, overhead, and profit.

Even if your solar panels are 2x as expensive as the typical panels, your actual total installation costs will only mildly increase. Lets run through a quick example:

Lets say you installed a 5kW solar system with standard panels. At this rate, youd pay:

  • Standard Panels: $3,200
  • Other equipment: $2,880
  • Supply chain, sales tax, inspecting, and permitting: $1,787
  • Sales, marketing, overhead, profit: $5,212

All this adds up to a total installation cost of about $14,560.

Now, lets say youve decided to install Sunpower solar panels. Yay! Lets even say that theyre twice as expensive as standard brands.

Since youre not actually changing anything except the panels, all costs would stay the same except for the panels themselves:

  • Sunpower Panels: $6,400
  • Supply chain, sales tax, inspecting, and permitting: $1,787
  • Sales, marketing, overhead, profit: $5,212

With Sunpower solar panels, your total installation cost jumps to $17,760 a 22% increase in your total installation cost. Not a huge jump.

All of a sudden, Sunpower solar panels cost doesnt seem that much higher now, does it?

Best Solar Panels Based On Your Region And Climate

After youve considered the efficiency, temperature coefficient, and warranty on any particular solar panel, its important to take the next step and think about your homes individual circumstance. Its no secret that solar panels are more often found in the Sun Belt compared to other parts of the country, but thats not to say that homeowners in the Northeast or Midwest should totally rule them out.

First, there are several factors that affect solar panel efficiencyfactors that can be impacted by your region and climate. These include irradiance, shading, panel orientation, temperature, location and latitude, time of year, and dust and dirt. For example, if you live in an area that doesnt get a lot of sunlight and your home is prone to shade and overcast clouds, youre not going to be able to produce as much clean energy for your home. When a panel is covered by shade, the power output is very loweven light shading can have a negative impact. In fact, subtle shading that covers a few cells or a single panel can reduce power output by 50% or more. This is why the orientation of your home in relation to the shade and wet weather patterns is so important.
