solar panel factory: Can we store energy on panels in 2021?
What is the durability of the solar panel?
The durability of a solar panel is at least 25 years, a standard service life guaranteed by the best solar panel factory. It can easily exceed 30 years of use with proper periodic maintenance of the equipment.
The solar plate: composition
A panel is the set of solar panels on the roof and its generating power is the sum of the individual powers of each plate.
Each board common in a solar panel is composed of:
- A tempered glass slide
- An organic material such as EVA (ethylene-vinyl-acetate)
- Connected solar cells
- Plus an EVA blade (or similar)
- A cover, which can be glass, tedlar, PVC or other polymers.
Solar panel factory guarantees the safety of the solar cells against impacts and also their thermal insulation.
Solar Panel Efficiency
But it is not just the physical strength of the solar panel that is involved in its durability. There is also the issue of the loss of efficiency of solar cells. Like any other material, silicon degrades over the years exposed to the sun and, therefore, losing its efficiency.
That is, its ability to transform sunlight into electrical energy. Despite the tragic irony, this annual loss is minimal, just 0.7% on average.
Solar panel factory Warranty
What matters in the end is the warranty given by the solar panel factory.
The best brands offer a 25-year efficiency lifetime with at least 80% of their initial generation, so keep your eye out. That is, a module with 275 watts of original power must, under warranty, be generating at least 80% of that power for at least 25 years.
What can be manufacturing defects of solar panels?
The warranty against manufacturing defects is 5 years, and it can reach up to 10 years in quality photovoltaic modules. But you will only be able to exchange the defective equipment if the origin of the solar plate is confirmed, otherwise there is no guarantee.
Therefore, it is extremely important to hire solar panel factory that use high-quality panels. Not to mention that, over the years, many manufacturers may have been bought, merged or even declared bankrupt.
So who gives the guarantee to the buyer (you) is the final seller, who becomes responsible for the guarantees given to the customer. As most of the quality boards are still imported, when purchasing a solar panel, it is important to check if the company has national representation.
Is it possible to store solar energy?
The answer is yes! It is possible to store solar photovoltaic energy in the same way as electricity from other sources: through batteries.
In USA, the first batteries common to store photovoltaic energy were lead-acid and nickel-cadmium batteries. And today there are still many isolated systems that use them for this purpose.
The disadvantage of using these batteries is that the cost is high, as their useful life is shorter than that of the photovoltaic solar generator. These two aspects make its use in local solar panel factory with access to the electricity grid unfeasible.
Storage Capacity of Solar Panel
However, in other countries this scenario is different. In countries in Europe, North America and Asia, for example, where photovoltaic systems are more advanced, the batteries common are lithium-ion batteries, such as Tesla’s Powerwall. This type of battery has been expanding rapidly thanks to its storage capacity and high durability.
Lithium-ion batteries are also common in electric cars. And this makes them a station to store the energy produced by the photovoltaic solar generator. That’s right, you did not misread! Imagine that in the future the population will be able to use the energy generated by your photovoltaic system to power your electric car
Ways of Solar Energy Storage
The best way to store solar energy is by batteries which solar panel factory offer. There are three types of batteries: lead acid, nickel cadmium and lithium ion. The first two are similar to those common in traditional cars. Lithium is the same common to power cell phones and Laptops and electric cars.
Lead acid battery
A pioneer in use in photovoltaic systems, the lead-acid battery consists of two electrodes, one of spongy lead and the other of powdered lead dioxide. However, even though they operate in solar energy storage, their high cost does not match their useful life.
Despite the possibility of being recharged several times, the nickel-cadmium battery also has a very high-value compared to its useful life. Still, it is mainly common for the operation of devices such as:
- cell phones
Solar panel factory fulfills its role of storing photovoltaic energy in the same way.
Lithium Ion solar panel Battery
With greater power and durability, the Li-ion battery is a viable option for how to store solar energy. This is made possible because it operates reactively with a large amount of energy in smaller and lighter batteries.
In addition, it is possible to charge only a part of the battery and it is not necessary to wait for it to fully discharge before recharging, as it does not have the known “battery addiction”.
Does a grid connect system need to switch to a battery-powered system?
Not! This technology of storing energy in batteries will complement On-Grid systems.
Modern solar panel Trends
In the coming years, world should follow the trend of other countries, which already use batteries together with grid-connected systems. Thus, the customer benefits in several ways, since in addition to being able to use the utility’s energy, they can also use the electrical energy stored in their battery.
Solar panel factory panels have an excellent durability, reaching up to 25 years of use. However, in order to take full advantage of this durability, in addition to a good installation, it is necessary to maintain constant preventive maintenance of the system.
Has your customer ever asked you about the system’s power generation and the problem was not technical?
Understand the benefits of preventive maintenance and how it can impact your system when not performed regularly.
What is preventive maintenance on a photovoltaic panel?
The preventive maintenance of solar panel factory is nothing more than a cleaning on solar panels and periodic visual inspection.
These inspections aim to identify scratches, stains, cracks or signs of breakage. These simple observations help to verify that the panels are working correctly.
Why does panel cleaning matter?
The dirt on the photovoltaic panels is one of the causes of decline in the system generation.
The accumulation of dirt, mainly generated by excess dust and pollution in large cities, can impact your system’s solar energy production!
Leaves, twigs, soot, bird droppings, pollution and dust all contribute to preventing sunlight from reaching the photovoltaic cells in your solar panels.
