ACOPOWER 12v 50W Portable Solar Charger Foldable Waterproof Solar Panel Kit & 5A Charge Controller USB 5V Output For Cell Phone
In most of the occasions, when we buy photovoltaic panels we only look at their price and we select the cheap photovoltaic panel . An unfortunate habit, since in most of the times a powerful photovoltaic panel with a higher price achieves a greater energy and economic saving, causing it to leave a lot more profitable in the long term.

What is important to know to choose your solar kit?
The main factor that must be taken into account is to know what will be the REAL performance that a certain solar kit that we will find in the market will provide.
For example, you can find kits of 24V daily use and with only 6 solar panels which are misleadingly indicated to offer performances of for example 12,000 watts (W). The deception lies in the fact that these kits can generate that energy but it will only be a couple of months and in summer, and calculated in the area of most radiation in the peninsula: Almeria. Which will mean that its use in other places will offer a lower result. In addition, the batteries of these kits will have been dimensioned for the energy generated by the plates in winter, therefore they will never be able to store the 12,000 watts generated in summer. That is, they will have batteries of 400Ah instead of 800Ah that would be necessary to accumulate 12,000 W.
We have detected this fact in countless stores of the competition. What it means a full-fledged deception for any potential buyer that by good faith or ignorance of the solar sector will not be aware of these facts. In addition, the main consequence of this fact will be that the customer will find a kit with a performance much lower than expected. The batteries will be the main element that will support all the weight of the bad sizing, and its useful life will be cut quickly because of that.
In Damia Solar all our solar kits for daily use always indicate the real performance that the kit will have in winter, and more specifically the month of December when there is less solar radiation. For example, the 4500W kit indicates the performance of the kit during this time of year. In addition it has been dimensioned starting from the average solar radiation that can be found in the peninsula, and which is the same as that of Madrid capital.ACOPOWER Portable Foldable Waterproof Controller Reviews
The color of a solar panel is 100% personal preference. The monocrystalline cells are dark gray-bluish or sometimes almost black; the polycrystalline cells lean towards the blue color, with multiple crystals that reflect different shades of blue. The color of the cell can be selected or changed. However, you can select the colors of the aluminum frame and the back sheet.
One point that is worth mentioning is that the panels with black background work at a higher temperature, therefore lose efficiency. The loss is not significant but the operating temperature of the array will increase, especially in hot climates. If efficiency is your ultimate goal, it is recommended to use panels with a white background; however, an all-black panel is not bad when appearance matters.
There has always been a great debate about whether the Chinese modules are worse or better than the European ones, and many users would be surprised if they knew that a good part of the European modules are made with photovoltaic cells manufactured in China, and the only thing that some European manufacturers do is to put the glass and aluminum frame and then your brand. Just as there are good and bad European products, the same happens with Chinese products. And it’s something that has nothing to do with some unscrupulous sellers selling solar panels of debris, or with defective wafers, at prices suspiciously cheap, or even that, at normal prices.
