1.Basic knowledge about solar panel

Solar panel is a system to generate the electrical power, according to relative data,nearly one hundred million families have install solar panel device.Actually the core component of the solar charger is the solar cell, the sensitivity of the solar cell is generally the whole visible light, whether it is sunlight or light.  In fact, the solar cell is just the common name of the device, the accurate name of this part should be "photosensitive cell" or "photocell", according to the manufacturing material is divided into silicon photocell and selenium photocell, its principle is the photoelectric effect. Another important is pv wire,whose function is to connect with solar cell,then transfer the electrical power to your house appliances.

2.Why is maintenance so vital?

If a family wants to install a whole solar panel system at the roof of his house,the average cost is aproaching $5000,this is not small amount,belong to the device we have got to maintenance.On the other hand,because the solar panle system is installed outdoor,the whether condition is not steady,so the you can't control much,that require us must do some basic maintenance.

3.Things you need do for daily maintenance

• Solar panels absorb sunlight into electricity, so it's important to keep the surface clean and always check for shade. 
• For polycrystalline silicon, monocrystalline silicon solar panels also need to pay attention to whether there is a fixed shield such as bird droppings, because it will produce hot spot effect, not only will affect the overall power efficiency, serious even burn through the panel.  Thin-film solar panels have no hot spot effect and are relatively easy to maintain.  
• Another thing you need to do is to prepare some pv wire,like you can reserve 100m,200m.Because wire or cable of solar panel belong to fragile parts.Most of situation of breakdown happened in solar panel would be the pv wire problem,such as the common used specification 12 awg pv wire ,the consumers in American will choose prepare about 200m pv wire in case anythings happened to their solar panel.

4.Warning about solar cable maintenance

• Don't hang any cloth or other things on solar panel,that would decline the efficiency of generating electrical power.

• Avoiding PV wire to be exposed to sun directly,although the insulation of PV wire owns the ability to resist the high temperature and ultraviolet ray,however you know if you pv wire exposed to sun too much time,will decrease the use age of it apparently. 

If you have read this article above and can do those suggestions in the future,such as pepare some pv wire, believe your solar panel will give you a bright daily life.
