Sun Power Solar Panels For Sale

Sunpower Cost And Financing Options

Sunpower can be a bit pricier, ranging up to $22,440. Therefore, they offer multiple financing options to assist you.

• Full purchase: This is the most cost-effective payment option. You save money by avoiding additional long-term costs when you buy a solar system up-front. You also can take advantage of any federal solar tax credits and rebates.
• Solar loan: You pay a low monthly fee to own the solar panels based on your credit. You still gain ownership of the solar power system and can take advantage of tax incentives with a solar loan. Still, the interest rates associated with financing options will add more to your costs over time.
• Solar lease: A solar lease means SunPower retains ownership of the panels, and you pay a monthly fee to purchase the power they generate. Think of this as if you are still paying your typical electric bill. Your monthly payments will be lower than an average power bill, but you cannot use any tax incentives.

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?

List Of Products By Brand Sunpower

SunPower is a worldwide leading solar company. Headquartered in Silicon Valley, its presence is split between the U.S. and Europe. The company was founded in 1985 by a professor of electrical engineering at Stanford University, although its beginnings date back to the 1970s with the aim of discovering a solution to the oil crisis.

Since then, the brand has experienced a very rapid and continuous growth, reaching today to produce high-end solar panels with very high efficiencies compared to other global manufacturers.

Today, SunPower is involved in the marine, aerospace and terrestrial sectors, with a focus on residential, commercial and energy storage installations. Thanks to their ambitions, they are able to offer cutting-edge technology also in the self-consumption market, as the technology used in missions outside of space is also applied in this type of modules.

The company has more than 30 years of experience in the manufacture of solar panels, more than 1,000 innovation patents and a record of 24.1% efficiency in a silicon solar panel. In addition, the total absence of metal contacts on the cells makes the solar panels practically failure-free. They are also pioneers in the field of solar sustainability and social responsibility, always looking towards a green and lasting future for our planet.

Within the technology offered by SunPower modules, two series can be highlighted the Performance range and the Maxeon range.

How Does Weather Affect Solar Energy

Weather conditions can impact the amount of electricity a solar system produces, but not exactly in the way you might think.

Perfect conditions for producing solar energy include a clear sunny day, of course. But like most electronics, solar panels are actually more efficient in cold weather than in warm weather. This allows the panel to produce more electricity in the same amount of time. As the temperature rises, the panel generates less voltage and produces less electricity.

But even though solar panels are more efficient in cold weather, they don’t necessarily produce more electricity in the winter than in summer. Sunnier weather often occurs in the warmer summer months. In addition to fewer clouds, the sun is usually out for more of the day. So even though your panels may be less efficient in warm weather, they’ll still likely produce more electricity in summer than in winter.

How Does A Solar Panel System Work

Here’s an example of how a home solar energy installation works. First, sunlight hits a solar panel on the roof. The panels convert the energy to DC current, which flows to an inverter. The inverter converts the electricity from DC to AC, which you can then use to power your home. It’s beautifully simple and clean, and it’s getting more efficient and affordable all the time.

However, what happens if you’re not home to use the electricity your solar panels are generating every sunny day? And what happens at night when your solar system is not generating power in real time? Don’t worry, you may still benefit through a system called “net metering.”*

A typical grid-tied PV system, during peak daylight hours, frequently produces more energy than one customer needs, so that excess energy is fed back into the grid for use elsewhere. The customer who is eligible for net metering may receive credits for the excess energy produced and can use those credits to draw from the grid at night or on cloudy days. A net meter records the energy sent compared to the energy received from the grid. Read our article on net metering and how it works.

Upgrade And Add Batteries

If you are just using DC power and you already have 2 existing batteries that are fairly new, the best plan is to install the solar and wait until your existing batteries wont hold a charge anymore. The solar that has been installed and the PWM charge controller will insure you get all the life left in the batteries. There are many types and sizes of batteries. RVs require heavy-duty deep cycle RV/Marine batteries. Cheap batteries will not last very long and will have to be replaced. Batteries should always be of the same type and upgraded all at once. Adding two new batteries to two old batteries will result in the new batteries holding the same charge as the old ones.

How Do Solar Panels Work

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, they generate electricity. Multiple cells make up a solar panel, and multiple panels can be wired together to form a solar array. The more panels you can deploy, the more energy you can expect to generate.

An Investment Worth Making

Solar is more affordable than ever, with PV costs dropping by more than 70 percent over the last decade according to the Solar Energy Industries Association, and a combination of federal and state tax credits further underwriting installation costs. Regulatory processes differ from state to state, and because the cost of power is different in each jurisdiction, so too is the time it takes to recoup ones investment. But no matter the location, PV panels pay for themselves over time.In a place like California with the third-highest electricity rates in the nation and 315 days of sunshine on average each year, theyre going to get a quick return on investment: five to seven years on average, Chapman explains. In other states, circumstances are changing rapidly. The state of Connecticuts price per kilowatt hour five years ago was about 11 cents. Now it has more than doubled, to about 23 cents, he explains. With solar, Youre buying into fixed-cost energy, hedging against future energy costs.

Are Sunpower Panels A Good Deal

Prices vary by location for all solar companies and SunPower is no different. Prices range from $3.28 per watt of solar panel to closer to $4 per watt in California, said David Saitta, SunPower’s senior director of residential sales. Different sources offer different average prices. The median cost in 2021 according to the consulting firm Wood Mackenzie was $3.28 per watt, but others report significantly lower numbers, like EnergySage, which reported averages ranging from $2.33 per watt in Arizona to $3.43 in Washington, DC.

While SunPower offers arguably the best equipment on the market, if you can meet your energy needs with less efficient and cheaper panels, you might find a better fit elsewhere. Still, SunPower offers different tiers of their Equinox system, and with more affordable options coming down the pike, SunPower could easily be the company that offers the best solar value for your home.

Does Sunpower Offer A Good Warranty

Solar panels are known for their durability, but a warranty is still a hugely important consideration in your purchase. Luckily, product warranties come attached to the purchase of most solar energy systems. These are good for at least 10 years, and the best cover performance up to 25 years.

Most solar panel product warranties cover the following:

• Defective products

Most solar panel product warranties do not cover the following:

• Underperforming systems resulting from poor installation or products
• Workmanship errors like roof leaks
• Accidents like tree branches falling on your panels or squirrels chewing through wires

SunPowers 25-year complete confidence warranty offers the following to address a number of the common pitfalls of solar warranties:

• All-in-one product warranty: Systems built with products from different manufacturers can result in a customer getting passed back and forth between companies as they shift blame for a failed part or system. SunPowers warranty, however, covers the complete system to ensure your problem is resolved in one place.

• Removal and shipping costs of defective parts: Conventional warranties usually dont cover the costs of removing and shipping defective or damaged parts. SunPowers warrantyensures noextra costs in replacing panels or other parts.

Overall, companies like SunPower and ADT Solar are making all-in-one system warranties more commonplace. The results are paying dividends.

What Is A Solar Panel

Solar panels are made up of silicone cells, which is the magic component for turning sun-rays into energy. Some panels will have a single, solid silicone cell , while others will have pieces of silicone that have been melted together . These cells are then fixed inside a frame, and covered with a protective glass.

When the panel is properly angled, it will capture sun-rays and convert it into DC energy. In turn, the DC energy gets converted to AC energy via an inverter, which you can use inside the home for your loads.

There Are At Least Three Ways To Mount The Semi

• They can be screwed down directly to the deck surface at each corner. We recommend a stainless screw with an oversized washer.
• They can be taped down directly to the deck with double sided Very High Bond tape. Because the back side of the panel has a pebbled surface like the front side for air circulation, the tape must have a foam core of at least 1/8 inch to secure the panel.
• The third method is our preferred method: Our CMP Semi-Rigid Walkable Solar Panel Mounting Kit. Aluminum extrusions are mounted on each side of the long sides of the panel and adhered to the deck surface with the tape. If the deck surface is not conducive to adhering the tape, the J extrusions can be screwed to the deck and the panel slid into position. This mounting method allows for the panel to be slid out of the extrusion for removal and cleaning of the deck surface.
