Harnessing the sun’s energy to produce electricity is gaining interest from eager consumers looking for cheaper, environmentally- friendly alternative power sources. As most of the resources available on earth are getting exhausted and their non-availability is forcing people to look for the optional solutions. And this energy crisis is the most problematic issue as its basic requirement for everything. That is the reason why now solar energy is becoming popular as an alternative to more costly fossil fuels. Although solar energy manufacturing is expanding across the globe, many manufacturers and distributors that install solar systems are seeking new methods of cutting manufacturing and installation cost. One solution that has the potential to streamline costs, decrease maintenance, improves durability and product life expectancy of the solar energy system is the transition from mechanical to solar panel adhesive. As an alternative to the mechanical fastener, it offers the benefits of reduced stress points, leaks, and corrosions, resistance to extreme environmental conditions.
The juncture box is an often overlooked piece of the solar panel. Usually pre-installed on a backside of the solar module, installers pay little attention until connecting panels. The PV junction box has a simple but important role, it housing all-electric bits on a solar panel and protecting them from the environment. Wires connect to diodes inside, providing an easy way to link panels together. It has bypass diodes that keep power flowing in one direction and prevent it from feeding back to the panel.
Every string is protected by a diode in the junction, and it serves as a gateway that allows an endless stream of power. There are two different junction box production techniques that are used in solar panels. These are:-
Soldering/Potting method:- With this technique, foils coming out of the solar panel are solder to the diodes in the junction box. The junction box then has to be potted or filled with the type of sticky material to allow the thermal transfer of heat, keeps the solder joint in place, and prevent it from falling. Once enough time has passed for sufficient curing of the potting material, the panel is good to go.
Clamping: – In this method, a simple clamping mechanism attaches the foil to the wires. There are no fumes or major cleanup as the soldering/ potting methods are fairly equal when comparing material and labor costs as a whole. The clamping box may be more expensive, but the labor needed to solder and pot the other boxes is often higher.
Solar design junction box options offered can be made available in the PV junction box potting method; foils coming out of the solar panel are soldered. That means it can sustain in all weather conditions without fear of system failure.
