Solar photovoltaic energy has become one of the most promising solutions for reducing electricity bills, achieving energy independence, and protecting against rising energy prices. More and more homes, businesses, homeowners\u2019 associations, hotels, industrial facilities, and farms are considering installing solar panels to generate part of the electricity they consume.
This is one of the most common myths when someone starts comparing quotes for solar panels. At first glance, many panels may look practically identical: a black or bluish surface, an aluminum frame, and a peak wattage listed on the technical specifications. That\u2019s why it\u2019s easy to assume that, if two quotes offer installations with similar power output, the logical choice is to go with the cheaper option. <\/p>\n\n
The problem is that a solar photovoltaic system shouldn\u2019t be viewed as an expense, but as an investment. When you install solar panels, you\u2019re not just buying panels for your roof. You\u2019re buying a portion of the electricity you\u2019ll consume over the next 25, 30, or even 40 years. And, as with any investment, it\u2019s not just how much you pay up front that matters, but how much you get in return over the system\u2019s entire lifespan. <\/p>\n\n
A more affordable panel may seem appealing in the initial budget, but if it has a shorter product warranty, higher degradation, poorer performance in hot weather, or more limited coverage, it may end up generating less guaranteed energy over time. In contrast, a premium panel may have a higher upfront cost, but it will produce more energy over a longer period and offer a much more robust warranty. <\/p>\n\n
The correct comparison should not be \u201chow much the installation costs,\u201d but rather \u201chow much each kWh of guaranteed energy that the installation will produce costs.\u201d<\/p>\n\n
A simple example: initial price vs. actual energy cost<\/strong><\/p>\n\n Let’s imagine two 10-kWp photovoltaic systems in M\u00e1laga, an area with very good solar radiation. To simplify matters, let’s assume that both produce approximately 15,000 kWh per year. <\/p>\n\n At first glance, the first system seems better because it costs less. But if you look at it as a long-term energy investment, the second one may be much more cost-effective, since it guarantees a greater amount of energy for many more years. <\/p>\n\n This doesn’t mean you always have to install the most expensive panel on the market. It means you need to compare options carefully. The ideal panel will depend on the type of customer, energy consumption, available space, the roof, the budget, how long you plan to stay in your home or business, and the level of warranty you want. <\/p>\n\n Whether it\u2019s a primary residence, a business with daytime electricity usage, or a facility where the customer is looking for long-term stability, the cheapest panel isn\u2019t always the best choice. In many cases, the best option is the one that offers the best balance between energy production, warranty, durability, and actual energy costs. <\/p>\n\n This myth is particularly dangerous because it is often disguised behind an eye-catching figure. It\u2019s common to hear statements like \u201cthese panels come with a 25-year warranty\u201d or \u201cthese others are guaranteed to be in production for 30 years.\u201d The problem is that, in the photovoltaic industry, the number of years in a warranty alone doesn\u2019t tell the whole story. <\/p>\n\n You need to know what kind of warranty it is, exactly what it covers, when it takes effect, who it protects, and what happens if the panel fails in 10, 15, or 20 years.<\/p>\n\n There are two main warranties for solar panels: the product warranty and the performance warranty. The product warranty covers defects or malfunctions in the panel itself. For example, if the panel stops working without having been subjected to an impact, a discharge, an external event, or improper handling. The performance warranty, on the other hand, guarantees that the panel will maintain a certain level of performance over time. <\/p>\n\n Confusion arises when more importance is placed on the production warranty than on the product warranty. A long production warranty may sound great, but if the product warranty is short and also does not cover labor, transportation, installation, removal, or travel, the actual protection for the customer may be quite limited. <\/p>\n\n Comparison: What People Usually Look At vs. What Really Matters<\/strong><\/p>\n\n One of the most important points is when the warranty period begins. For some manufacturers, the warranty period may begin when the manufacturer sells the panel to the distributor, not when the end customer installs it in their home or business. This means that a panel may have been in storage for months or years before being installed, and that part of the warranty may already have expired. <\/p>\n\n In high-quality installations, this is handled differently. Ideally, the panels should be properly registered, and the customer should have a clear, traceable warranty tied to their installation. For example, with premium solutions like SunPower Maxeon, the warranty can cover up to 40 years for both the product and its performance, offering much more comprehensive coverage than many conventional panels. <\/p>\n\n A warranty isn’t just a nice piece of paper to include in the budget. It’s a fundamental part of the investment. If a facility is designed to generate energy for decades, the warranty must be up to the task. <\/p>\n\n From the outside, two solar panels may look very similar. They may even have similar power ratings and dimensions. But on the inside, the technology can be very different. And that internal difference has a direct impact on the panel\u2019s power output, degradation, mechanical strength, and lifespan. <\/p>\n\n Conventional solar cells typically use visible conductive lines on the front, known as bus bars. These lines collect the electricity generated by the cell and conduct it to the panel\u2019s circuit. It is a widely used technology and can function properly, but it has limitations. If the cell cracks, breaks, or develops microcracks, these electrical pathways can be affected, leading to losses in power output or hot spots. <\/p>\n\n Microcracks are one of those problems that aren\u2019t always visible to the naked eye. A panel may look perfect from the ground, but it may have sustained internal damage during transport, handling, or installation. They can also be caused by bending, vibrations, hail, temperature changes, or improper foot traffic on the panel. In large-format panels, careless handling can create stress in the glass and the cells. <\/p>\n\n This is where technologies like Maxeon cells make a significant difference. SunPower Maxeon cells use a back-contact architecture, eliminating the main contacts from the front. In addition, they incorporate a copper substrate that provides greater mechanical strength and helps dissipate heat. This improves the cell\u2019s durability and reduces the risk of internal fractures that could affect performance. <\/p>\n\n And heat matters a lot. Solar panels generate electricity from light, not from heat. In fact, when the panel\u2019s temperature rises too high, its efficiency can drop. That\u2019s why a cell that manages temperature better and degrades less over time can provide more useful energy throughout its lifetime. <\/p>\n\n Key differences between a conventional cell and a premium Maxeon-type cell<\/strong>:<\/p>\n\n That\u2019s why, when someone says that \u201call panels are the same,\u201d they\u2019re really only comparing their outward appearance. What makes the difference is on the inside: the cell, the materials, the encapsulation, the glass, the frame, the connectors, the warranty, and the manufacturing controls. <\/p>\n\n In solar energy, what you can’t see is often what matters most.<\/p>\n\n This myth stems from a flawed comparison. Many people notice that a solar panel may have, for example, 415 Wp, while the associated microinverter has a lower maximum output power. From there, the quick conclusion is often: \u201cThe microinverter is limiting the panel\u2019s output, so it produces less.\u201d <\/p>\n\n The reality is more nuanced. Yes, there may be specific times of the day when the panel can produce more power than the microinverter can handle. This phenomenon is often called \u201cclipping\u201d or \u201cpower clipping.\u201d But to determine whether a system produces more or less power, you shouldn\u2019t look only at the midday peak. You have to look at the total energy generated throughout the day, the month, and the year. <\/p>\n\n A traditional string inverter requires a series of panels to reach a minimum voltage before it begins operating. As a result, under certain conditions, it may start later in the morning and stop earlier in the afternoon. In contrast, microinverters operate on a panel-by-panel basis and can begin generating power even at very low levels of sunlight. This allows for better use of the early morning hours, the late afternoon hours, and situations involving partial shading, different orientations, or varying tilt angles. <\/p>\n\n On a perfect, spacious roof with no shadows and all panels facing the same direction, a string inverter can be an excellent solution. But in many real-world homes, especially in residential areas of M\u00e1laga and the Costa del Sol, roofs have multiple slopes, chimneys, roof boxes, antennas, partial shadows, or separate sections. In such cases, microinverters can offer a clear advantage because each panel operates independently. <\/p>\n\n Microinverters vs. String Inverters: When Is Each Option Best Suited?<\/strong><\/p>\n\n The right question isn’t whether microinverters are better or worse in every case. The right question is: Which technology is the best fit for this roof, this energy consumption, and this customer? <\/p>\n\n At Ubora, we don\u2019t advocate a one-size-fits-all solution. We design each installation based on the specific circumstances of the project. There are homes where microinverters make a lot of sense, and there are installations where a string or hybrid inverter is the most logical choice. The key is not to sell a technology out of habit, but to choose it based on engineering principles. <\/p>\n\n Solar mounting structures often receive less attention than panels or inverters, but they are a critical part of the installation. After all, they are responsible for keeping the panels secured to the roof for years, withstanding wind, rain, humidity, solar radiation, temperature changes, vibrations, and, in many areas, a marine environment. <\/p>\n\n A photovoltaic system isn’t installed to last just a few months. It’s installed to operate for decades. That’s why the mounting structure can’t be a generic component or a makeshift solution. It must be specifically designed for photovoltaic systems and be compatible with the type of roof on which it is installed. <\/p>\n\n When a quote simply lists \u201caluminum structure,\u201d information is missing. A structure from a reputable manufacturer\u2014complete with testing, warranties, and technical documentation\u2014is not the same as a generic profile adapted from another application. Nor is a tile roof the same as a sandwich panel, a flat roof, a pergola, a concrete structure, or a facility near the sea. <\/p>\n\n In areas such as M\u00e1laga, Torremolinos, Benalm\u00e1dena, Fuengirola, Marbella, Estepona, Rinc\u00f3n de la Victoria, and Nerja, the marine environment can be a decisive factor. Salinity accelerates corrosion processes and can affect certain materials if they are not designed for that environment. Therefore, for facilities near the coast, it is advisable to verify whether the structure is suitable for a marine environment and whether the manufacturer honors the warranty at that location. <\/p>\n\n A good structure should provide support, but it must also be compatible with the roof. Poor installation can lead to leaks, movement, noise, broken shingles, or structural problems. And the worst part is that many of these problems don\u2019t show up right away. They emerge over time, once the installation has been exposed to the elements for years. <\/p>\n\n What Should a Structural Line Item Include in a Professional Budget?<\/strong><\/p>\n\n If you’re going to compare quotes, don’t just look at the panels and the inverter. Also consider how those panels will be mounted over the next few years. The mounting structure is one of those components that, if done right, goes unnoticed. But if it’s done poorly, it can become a serious problem. <\/p>\n\n The inverter is one of the most important components of a photovoltaic system. Its basic function is to convert the direct current generated by the panels into alternating current that can be used by a home or business. But today\u2019s inverters can do much more than that. <\/p>\n\n An inverter can manage batteries, control critical loads, provide backup power during outages, integrate with generators, communicate with monitoring systems, limit power feed-in to the grid, coordinate with electric vehicle chargers, or form part of a broader energy management strategy.<\/p>\n\n Therefore, it is a mistake to say that all inverters are the same simply because they have the same power rating. Two 5-kW inverters can have completely different performance, durability, connectivity, compatibility, and scalability. <\/p>\n\n Some inverters are designed for simple residential installations. Others have a more industrial, robust, or flexible design. Some use high-voltage batteries, while others use low-voltage batteries. Some allow for a generator connection, while others do not. Some feature a touchscreen for on-site diagnostics, while others rely almost entirely on the app. Some offer more communication options, while others are more closed-off. <\/p>\n\n This doesn’t mean that one is always good and the other always bad. It means that every project needs the right investor. <\/p>\n\n A household that simply wants to lower its energy bill with a straightforward installation may need a different solution than one that wants a battery, backup power, an electric charger, an air-source heat pump, and advanced management features. Similarly, a business with stable daytime energy consumption does not have the same needs as a residential customer with nighttime energy consumption who plans to install an electric vehicle. <\/p>\n\n Practical Comparison: What to Look for in an Inverter<\/strong><\/p>\n\n At Ubora, we view the inverter as part of an energy system, not as a standalone unit. Today you can install solar panels, but tomorrow you might want to add a battery, an electric vehicle charger, a heat pump, a backup system, or more advanced energy management. If the inverter isn\u2019t chosen correctly from the start, that upgrade could be more difficult\u2014or even impossible. <\/p>\n\n This myth is one of the most sensitive, because it directly affects the safety of the installation. Many estimates include a very generic line: \u201celectrical safeguards included.\u201d The problem is that this phrase says practically nothing. <\/p>\n\n We do not know which brand will be installed, what type of protection is included, whether there is protection for both direct and alternating current, whether surge protection is provided, what type of enclosure will be used, how the panel will be wired, what the quality of the components is, or whether the system is designed to accommodate future expansions.<\/p>\n\n Electrical safety devices are not just a formality. They are designed to protect people, homes, equipment, the inverter, the wiring, and the entire system from short circuits, ground faults, power surges, and electrical failures. In a photovoltaic system, there is also a direct current component that requires special attention. <\/p>\n\n A solar installation operates every day for many hours. The materials heat up, cool down, expand, contract, and withstand varying loads. A poorly executed connection can eventually lead to overheating, loose connections, electrical arcs, or malfunctions. And this doesn\u2019t always happen right away. It can develop over time. <\/p>\n\n A very clear example is how to connect terminal blocks and terminal strips inside an electrical panel. If a mechanism is not designed to properly accommodate both components and they are inserted haphazardly into the same clamping point, the connection may not be securely fastened. Over time, that connection can loosen, overheat, and become a safety hazard. <\/p>\n\n That’s why working with top-tier brands and the right tools isn’t just about showing off technical expertise. It’s about security. <\/p>\n\n Electrical Safety Measures: Basic Estimate vs. Professional Installation<\/strong><\/p>\n\n Electrical safety should not be the area where cuts are made to reduce costs. If an installation is going to be in operation for decades, the electrical panel and its protective devices must be on par with the rest of the system. <\/p>\n\n On many tile roofs, the solar mounting structure passes through the tiles and is anchored to the roof deck or underlying support. Anchoring systems\u2014and, in many cases, chemical anchors\u2014are used for this purpose. So far, so good. The problem is assuming that just any chemical anchor is suitable for a photovoltaic installation. <\/p>\n\n A solar installation is located outdoors, exposed to the sun, rain, humidity, temperature fluctuations, wind, and vibrations. In coastal areas, it may also be exposed to a salty environment. Therefore, the mounting system must be designed to withstand these conditions for many years. <\/p>\n\n Not all chemical anchors are designed for the same use. Some products may be suitable for indoor or less demanding applications, but may not be the best choice for a solar installation exposed to the elements. Others are formulated to offer better resistance to outdoor conditions, humidity, or more severe conditions. <\/p>\n\n The situation here is similar to what happens with panels: the cheapest material may seem to work well on the first day, but that doesn’t mean it’s suitable for lasting 25, 30, or 40 years on a roof.<\/p>\n\n Furthermore, it\u2019s not enough to simply choose a good product. You also have to apply it correctly. The drill bit must be the correct diameter, the hole must be thoroughly cleaned, the resin must be mixed properly, the curing time must be observed, and the anchor must be installed to the correct depth and with the proper torque. If any of these steps is done incorrectly, the anchor may not perform as intended. <\/p>\n\n What can go wrong if the anchor isn’t suitable?<\/strong><\/p>\n\n In a photovoltaic system, mounting isn\u2019t just a minor detail. It\u2019s what holds the entire system in place on the roof. That\u2019s why, at Ubora, we pay close attention to both the materials and the installation process. It\u2019s not just about ensuring the system looks good on the day it\u2019s commissioned\u2014it\u2019s about making sure it remains safe for many years to come. <\/p>\n\n This myth is very common because MC4 connectors are constantly mentioned in the solar industry. The term \u201cMC4-type\u201d is frequently used in technical specifications, quotes, and sales conversations. But there\u2019s one important detail: MC4 is a registered trademark of St\u00e4ubli. <\/p>\n\n That means that an original MC4 connector is a St\u00e4ubli MC4. Other connectors may be compatible or \u201cMC4-type,\u201d but they are not necessarily the original and may not have the same quality, tolerances, watertightness, or durability. <\/p>\n\n It may seem like a minor detail, but it isn’t. The connectors operate in the DC portion of the system, typically outdoors, where they are exposed to solar radiation, humidity, temperature fluctuations, water, dirt, and mechanical stress. A faulty connector can cause power losses, overheating, insulation failures, water ingress, or safety issues. <\/p>\n\n Furthermore, connector compatibility isn’t always as straightforward as it seems. Two connectors from different manufacturers may fit together physically, but they may have slight differences in tolerance, gasket, contact pressure, or material quality. These differences may not be noticeable at first, but they will become apparent after years of exposure to the elements. <\/p>\n\n In high-quality installations, connectors must be genuine or from reputable manufacturers; they must be crimped using the proper tool and installed in accordance with the manufacturer\u2019s instructions. They should not be left lying in areas where water can accumulate, nor should connectors from different brands be mixed indiscriminately. <\/p>\n\n Solar Connectors: Why They Matter So Much<\/strong><\/p>\n\n Connectors are small and don’t usually take center stage in a budget. But in photovoltaics, problems often stem from the small details. And a connector that is in poor condition, poorly crimped, or of low quality can compromise an installation that otherwise seemed fine. <\/p>\n\n This myth sums up all the previous ones. If all panels were the same, all warranties covered the same things, all inverters had the same features, all mounting structures were equally durable, all safety features were equivalent, and all connectors offered the same level of safety, then perhaps it would make sense to choose a company based solely on price. <\/p>\n\n But the reality is exactly the opposite.<\/p>\n\n A well-executed photovoltaic installation requires research, engineering, electrical design, roof analysis, material selection, professional installation, regulatory approval, monitoring, and after-sales service. It\u2019s not simply a matter of placing solar panels on a roof. <\/p>\n\n A good installation company should be able to analyze the customer\u2019s actual energy consumption, recommend an appropriate power rating, anticipate future needs, clearly explain the materials, justify technical decisions, properly obtain the necessary permits for the installation, and respond if a problem arises.<\/p>\n\n At Ubora, we take a comprehensive approach to energy. We specialize in solar power, energy storage, electric vehicle chargers, geothermal heating, home automation, and energy management. This allows us to design systems that go beyond simply \u201cinstalling panels,\u201d but instead take into account how the customer consumes energy today and how their needs may evolve in the future. <\/p>\n\n For example, a home might start with solar panels and later add a battery or an electric vehicle charger. A business might install a self-consumption system now and later need advanced monitoring, demand control, or integration with other energy uses. A community might move from considering an individual installation to exploring collective self-consumption. A hotel can combine solar power, geothermal heating, energy storage, and energy management to improve its efficiency. <\/p>\n\n The difference between one company and another isn’t just about the budget. It’s about the technical decisions it makes before, during, and after installation. <\/p>\n\n How to Identify a Professional Solar Company<\/p>\n\n A professional solar company doesn’t try to sell the same solution to everyone. It listens, analyzes, designs, and proposes the option that makes sense for each specific situation. And it must also be able to tell when something isn’t a good fit, when a battery isn’t cost-effective, when a roof isn’t suitable, or when a seemingly cheap quote could end up being expensive. <\/p>\n\n Solar photovoltaic energy is a mature, cost-effective solution that makes a lot of sense for homes, businesses, communities, and industries. But for it to work well for years to come, it\u2019s not enough to simply install \u201csolar panels.\u201d You need to design a comprehensive, safe, and future-proof energy system. <\/p>\n\n The biggest mistake when comparing quotes is to focus solely on the initial price. A cheaper installation may seem attractive today, but it could end up costing more in the long run if it produces less, wears out sooner, comes with limited warranties, uses low-quality materials, or lacks good after-sales service. <\/p>\n\n The right question isn’t “Which system is the cheapest?”, but rather “Which system will guarantee me more energy, greater safety, longer durability, and fewer problems over the next few years?”<\/p>\n\n At Ubora, we design solar power systems with a focus on engineering, quality, and comprehensive energy management. We work with high-performance solutions for homes, businesses, communities, industries, and customers who are looking for more than just a low price: they want a system that is reliable, safe, and built to last. <\/p>\n\n If you’re considering installing solar panels and want to know which solution is best suited for your home or business, we can help you assess your situation and design a system built to generate energy for decades to come.<\/p>\n\n At Ubora, we analyze your energy consumption, your roof, and your energy goals to design a safe, cost-effective, and future-proof solar power system.<\/p>\n\n Request your personalized assessment and find out how much you can save with a high-quality solar installation.<\/p>\n\n If you’d like to learn more about the myths surrounding solar energy, we invite you to watch the full video on our YouTube channel:<\/p>\n\nConcept<\/strong><\/td> Affordable Installation<\/strong><\/td> Premium Installation<\/strong><\/td><\/tr> Installed capacity<\/strong><\/td> 10 kWp<\/td> 10 kWp<\/td><\/tr> Estimated Initial Investment<\/strong><\/td> \u20ac5,000<\/td> \u20ac7,500<\/td><\/tr> Estimated annual production<\/strong><\/td> 15,000 kWh <\/td> 15,000 kWh<\/td><\/tr> Product warranty considered<\/strong><\/td> 15 years<\/td> 40 years<\/td><\/tr> Approximate guaranteed energy<\/strong><\/td> 225,000 kWh<\/td> 600,000 kWh<\/td><\/tr> Estimated cost per kWh (guaranteed)<\/strong><\/td> 0.022 \u20ac\/kWh<\/td> 0.012 \u20ac\/kWh<\/td><\/tr><\/tbody><\/table><\/figure>\n\n Myth 2: \u201cAll solar panel warranties are the same\u201d<\/strong><\/h2>\n\n
