Maintenance and sustainability
Photovoltaic systems need a lot of maintenance. Since most of the time they are exposed to inclement weather, they need constant care. In case you feel any reduction in efficiency, call a technician immediately. To maintain yourself, clean the glass cover in parts (remove excess dust or pollution that accumulates) with a little water and a soft cloth, it is best to do it every two months. Verify that there are no loose or broken terminals.
How much they cost?
One of the main concerns is the cost of solar panels. Regularly they are not cheap, in Mexico their price varies, you can find them from 3 thousand pesos up to 30 thousand approximately, depending on the size. But the truth is, the expense you will make is worth it since you will only pay once and the benefits will be reflected in your electricity bill, since the consumption is reduced by more than half, if you think it is a good refund for the initial investment.

Solar energy in certain places or properties can not replace grid electricity but optimize it, because if you also do bioclimatic spare parts to achieve better use of energy, in addition to saving a lot of kilowatts in the operation of the house. In most countries to a greater or lesser extent you can use solar energy that is free,Sunpower Lightweight Solar Connector Applications Reviews
Considerations prior to the installation of solar panels.
To take advantage of the advantages of placing solar panels at home, it is convenient to have some considerations about their installation.
It is important to know the performance we can obtain according to our location, there is a map in which the climatic zones are classified according to the solar radiation or the annual sunshine hours. To capture the maximum solar radiation, we must orient the panels to the south.
It is also necessary to take into account the inclination of the panel that will depend on variables such as use or geographical latitude and a fixed value (18º), which must be added to it, in order to obtain optimum performance.
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.
