Sunpower vs. Renogy - Which One Has Better Solar Panels for You

This article will cover some of the pros and cons of the two leading brands: SunPower vs. Renogy.

If you were thinking of getting a solar panel installation but were unsure which one would provide you with the best value for money, then this may be helpful to you.

What are Renogy’s Claims & Business Model?

Renogy is a manufacturer and distributor of solar energy products in Europe. In addition to the products they manufacture, they sell a range of other energy services.

They claim to be the world leader in the business of solar energy production, distribution and sales.

In this article, we will examine the claims made by Renogy, the business model they are using to achieve their goals, and the risks that come with the business model they are using.

What Are Sunpower’s Business Model & Product’s Claims?

SunPower’s business model is to sell solar equipment and services at a profit.

The company does not generate electricity but sells electricity generated by the solar panels it installs on customers’ roofs.

SunPower’s marketing claims are that its solar panels generate more energy than they use and that its meetings are the most efficient industry.

However, the company’s own research shows that these claims are misleading.

Cost per Watt: How Much Can I Save?

Solar energy is one of the best ways to save on energy costs, especially if you live in a location with sunny weather year-round.

But, as with any technology, different types of solar energy systems are available to you. And each of them has other pros and cons. When choosing between solar energy systems, there are two significant considerations: cost and savings.

Renogy solar panels are the most cost-effective and best value on the market. They are the lowest cost option for any residential or commercial installation.

On top, Renogy employs an anti-reflective, low iron tempered glass with high transparency of up to 91.5 per cent.

Compared to traditional solar panels, it converts more direct sunlight to electrical power.

The average cost to install a Renogy solar panel system is $4.00 per watt. This includes the purchase price of the panels themselves, as well as installation costs.

The average cost of solar power is usually measured in terms of cents per kilowatt-hour (kWh).

To calculate the cost of your solar installation, you can multiply the wattage of your system by its price per watt.

SunPower residential panels feature among the market’s top efficiency and power ratings. A SunPower solar system will cost you at least $3.30 per watt, which is around $19,800 before incentives for a 6 kW system.

Comparing Power Quality Renogy vs Sunpower: What’s the Difference Between Sunpower and Renogy Solar Panels?

Maintenance Costs: How Much Should I Expect to Spend?

If you want to maximize your return on investment, the most critical question is, “how much money would you save each month on electricity bills?” how quickly does your solar system recoup its investment?”

Thin-film solar panels are less expensive than traditional panel systems because they don’t require special tools and machinery for installation.

They can be installed quickly with a single worker and moved from site to site without any tools or equipment needed. These panels can be installed on various surfaces, including roofs, walls, and fences.

One of the most common issues with solar shading is that it does not allow a consistent amount of light to pass through the panel.

This can be a problem if you want to use the shade during the day and open it up at night.

In these instances, you need to adjust the panel’s angle to increase or decrease the amount of light that passes through. This can be a very tedious process and can require a great deal of trial and error.

That aside, several factors can affect how long it will take for your solar energy investment to pay for itself, including the quality of your system, the quantity of sunshine hitting your solar panels, whether you lease or buy the system, the price per watt, and any applicable tax credits.

These factors may be calculated for you by reputable solar vendors, who can show you how quickly your system will pay for its energy savings.

If you’re interested in installing a solar panel system on your roof, you’ll need to know how much it will cost. 

Nationally, maintaining a solar panel installation costs between $140 and $180; however, warranties cover the cost of many services.

The most typical service you’ll need is a yearly inspection, which costs around $150 on average in the United States.

The second service you’ll most likely want is solar panel cleaning. Most warranties do not cover this, and you should budget $12-20 per panel for a repair or replacement.

A typical home has between 15 and 35 solar panels depending on how much power you consume each year.

These numbers run similar between Renogy and Sunpower panels.

Warranty Claims: Sunpower vs Renogy

It’s not only you that has trouble figuring out how to compare solar panel warranties.

Understanding the differences in warranty coverage across various manufacturers may be like comparing apples and oranges, even if you spend hours poring through pages of dense documentation!

Installing solar PV panels in your home or company increases your chances of having a trouble-free operation for decades.

However, issues with solar panels can arise from time to time, and if this happens to you, you should know that your entire system will not be made useless by the failure of just one solar panel.

Most likely, if you have a panel failure, the remainder of your system can continue to function without it.

However, some panels fail in ways that negatively influence the performance of their neighbours.

The solar panel’s product warranty insurance covers you if you need to replace a defective board.

A single solar panel typically costs between $150 and $300.

If a problem arises with your solar panel, you can rest easy knowing that your service and support requirements will be taken care of if you compare the warranties offered by various panel manufacturers.

A panel manufacturer’s technical requirements and business operations should be considered alongside the manufacturer’s product warranties.

The manufacturer may give you a replacement panel and even pay for the shipping and labour costs to replace it in some situations.

So we met with some of the most popular solar panel manufacturers and learned more about their warranties and what to look out for.

Regarding warranty terms, Sunpower, with their 25 years warranty, has a better deal than Renogy, which only offers a 10-year warranty period after the purchase.

What does a solar panel warranty cover?

Every year, the amount of power generated by a solar panel drops. This is true, according to all solar panel manufacturers.

Due to an excellent solar panel warranty, you may be sure that your panels will not lose more than 10% to 20% of their power production capacity throughout the first 25 years.

Another way to say it is that panel manufacturers often guarantee that their panels will supply 80-90 per cent of their rated power output after 25 years.

If you have any problems with your solar system, the performance warranty coverage may be a strong indicator of the panel manufacturer’s support policies.

Regarding product warranties, it is easier to demonstrate that you have an issue with your panel that should be covered by a warranty.

The causes behind this are too complex for this short explanation.

The 25-year performance warranty (i.e., minimal deterioration) is a better predictor of the panel’s intended degradation behaviour than its manufacturer’s support procedures.

However, it should be noted that many panels do not come with a 25-year performance warranty.

This means that you have to rely on the manufacturer’s support procedures to assess whether your panel is covered or not.

This is where things get complicated, as seen in the following sections.

Warranty length is one of the most important factors when looking at the level of manufacturer’s support. A 25-year warranty on your solar system may be a strong indicator of the manufacturer’s support policies.

Ultimately, it all comes down to what the company provides for free and what they charge.

Several companies offer a 30-day money-back guarantee if you are unsatisfied with their work, but they do not provide any performance warranty.

As a performance warranty, the manufacturer usually covers any repairs to the system or the panels for a limited period.

This period is usually a certain number of years, after which the panel is considered obsolete.

Not to mention, most panels degrade at a specific rate due to aging.

They get weaker over time, so it is essential to know the expected degradation rate of your panel before installation.

 If your solar panel declines faster than stipulated in the warranty, your solar panel manufacturer may repair or replace it. Some manufacturers may even pay the cost of shipping and labour to replace a solar panel.

In this sense, Sunpower also offers a better warranty deal by promising 90% performance output after 25 years, compared to that 84% from Renogy.
