INTRODUCTION
Energy needs are increasingly becoming the basic needs of every human being. Man require an increase in the amount of energy for industrial, commercial, domestic, agricultural, and use of transportation. Needs energy electricity already Becomes part important for human life. All activities man started from activity house ladder up to you activity industry very depend will energy electricity. The more tall amount population, so the more big also needs will energy electricity for Fulfill his needs.
The current energy needs, mostly fulfilled by fossil fuel energy such as oil, coal and natural gas. However, the current supply of energy is decreasing. If not soon handled, the possibility of an energy crisis is unavoidable. For that innovation about alternative energy, especially from unlimited resources, it is very needed as technology develops, to meet energy needs Public in time which will come. And wrong one alternative which can applied is innovation regarding cell technology Sun.
Cell Sun is a device which change energy ray sun Becomes energy electricity with process effect photovoltaic. Energy Sun photovoltaic is technology technology which used for utilise energy sun into direct current with a semiconductor device which normal our say as panel Sun ( sollar cell ) (Purwoto ,2018:1 ).
Cell Sun is device which could change energy light sun Becomes electrical energy by following the photovoltaic principle. Solar cells are an energy technology that direct. Electrical energy can be created without the help of moving fluids such as steam or gas. Solar cells also do not require mechanical movement like Rankine cycle or Brayton cycle. Panel Solar Cell there is a number of type that is: a. Cell Sun silicone monocrystal

b. Cell Sun silicone polycrystal
Making cell Sun silicone as source current constant, no as simple making silicone for semiconductor material. by quantitative solar cell polycrystal occupy the place second. Efficiency located Among 10-15% more low from cell monocrystal. c. A-silicon (a-Si) solar cells A-silicon solar cells arrangement the atom no order, that solar cell this on basic more productive, where absorption of asilicon to light is almost 40 times more good from silicone crystal . Profit cell Sun a-silicone among others: Power absorption big, area band height, Need ingredient more a little, and Possibility method making could automatically. The downside is the efficiency still low, consequence prisoner inside big and current photo which caused very small. The solar panel also consists of various parts as following: a. Cover Glass Cover Glass is component which protect solar panels from the input of dirt or water that can interfere with the performance of the solar panel. Materials that used consist from ingredient clear or normal use glass or mica. b. Adhesive Transparent Adhesive which working for glue electronic device. Transparent adhesive is used on layer in on anti reflective and in lower glass protector or cover from panel Sun c. Layer antireflective Layer antireflective (layer anti-reflection) is a thin layer with an optical refractive index which located in Among semiconductor and air which working as deflector direction light to semi-conductor so that could catch light more many.

d. Material Semiconductor
Semiconductor is component main on panel Sun. function alone is as absorbent light from ray sun. semiconductor arranged from combined two material semiconductor that is p-type and n-type e. Back Contacts.
Back contact is the part of the back protector of the solar panel which acts as a conductor. ingredient from back contact alone made of from metal. f. frame Outside The outer frame of the solar panel is made of high strength aluminum and strong to direct impact

Solar Chargers Controller
Solar charger controller electronic circuit which serves to control the DC current that will injected to battery and take from battery towards the load. in addition to the above function has a function Another is as a current limiter so that it doesn't happen overcharging and overvoltage which will injected from panel Sun Inverter Inverter is device electronics power which has a function as a modifier or converter voltage from voltage DC to Voltage AIR CONDITIONING.

Accumulator (battery)
The accumulator (battery) which is often referred to as battery is converter energy chemical Becomes electrical energy with direct voltage (DC). battery also commonly referred to as electrochemical influence to substance chemical the reagent, so that called as a secondary element.
