Solar Panel Tutorials


Solar Panel is the first component of solar energy system. Light particles called photons produces electrical current when they strike silicon or wafer surface. Only .5 or half a current is produced by a single solar panel, But about 17 volts peak output is been generated by a 25*54 inches 12 volts typical solar panel

Solar panels can be wired in series to increase voltage or in parallel to increase current (amperes) so as to meet the different volt and current that may be required to power different load capacities. Joepascal solar/inverter solutions offers technical assistance in this area to our followers

There are mainly three type of solar panel which are;

Mono crystalline; This is the most efficient and expensive solar panel and that’s because of the complicated crystal growth process in which it was build. Individual pure silicon rod are produced and sliced into .2 to .4mmthick disc or wafers which are in turn processed into a single cell and wired together into solar panel and this is why joepascal solar world recommends this solar panel

Polycrystalline; this is slightly less efficient because it’s not built in single crystalline but in large block of many crystals which makes their appearance look like a striking shattered glass and this makes them slightly less expensive unlike the monocrystalline in some cases in we recommend this depending on the location of use weather factor
Amorphous; metals or glasses are used to deposit some thin layers of silicon them to form solar panels therefore they are not really crystal and they are much less efficient and as such very cheap. And we in joepascal sola/inverter solution never recommend the use of this solar panel
Solar panels installations; In Joepascal solar world we understand that location is one of the primary factor to put to consideration when it comes to solar panel installation, shades or shadows on solar panel during peak hours will not only reduce the output but can cause damage to your panels, even though some manufacturers advertise solar panels that can withstand shadows but they are build with diodes which on it’s own reduces current so we advice choosing very good location for your installation than to go for the second best.
Joepascal solar/inverter team also recommends that though we need maximum sunlight on the solar panel but the heat build-up also decreases solar panels efficient as the temperature builds-up, therefore one should endvour to space panels to allow flow of air during solar panel mounting as it makes it cooler and therefore cause wind resistance of the whole array

Basic solar panel mounting array are;               Fixed,      Adjustable and    tracking

Fixed solar panel mount; This is the most simple and least expensive type of solar mount panel system because it is permanently stationed but should face the equator this is mostly used in Africa especially in the west because of the favorable climate condition where sunlight is almost constant through the year but only for some few serious raining season period some sunless cloudy weather are experienced but even at that the sun is still sure in just couple of hours , unlike as it is in the western world.
Adjustable solar panel mounting; Through the year this type of solar panel mounting can adjusted up to two or three times through its angle of inclination (tilt) maybe during serious raining season as the earth orbits the sun causing seasonal change.
Tracking solar mounting; To maximize the solar radiation that solar panels receives the tracking solar panel mount tracks the movement of the throughout the day, a single or a two way axis tracker can be used, we in joepascalsolarworld admit that this type of mount system is the most efficient though more expensive that the rest.
