Off Grid 15 KWp PV Power System

provide an independently regulated power supply which has at least the same reliability and quality as a public power grid

in areas without a public grid, PV off-grid systems provide one of the most cost effective and ecological

solutions for a safe and reliable power supply

. . . . .

ϒ simple operation!ϒ Low maintenance !

ϒ Safe and reliable power supply! ϒ Easy and cheap installation!

ϒ Affordable! ϒ Global application field!

WORKING PRINCIPLE

At day time , electrical energy generated by PV module directly supplied to the load through inverter

At that time the energy will fill battery as well

To prevent over charging/discharge, then used solar charge controller in the system

Electrical energy produced by PV Module depend on sun radiation on site/location and PV Module efficiency

Maximum sun intensity : 1,000 watt/m2 If PV module efficiency 14% then maximum energy Production is : 140 watt/m2

Energy  come  from  PV  <  Load  :  1.  At  Cloudy  *  2.  Evening  before  sunset  *  Load  supply  come  from  PV  energy  and  the  rest  come  from  baLery  supply  

 At  Night  :  All  energy  supply  come  from  baLery  that  was  filled  by  solar  (PV)  energy  at  the  day  Qme  

At  that  Qme  inverter  convert  DC  current  from  baLery  to  AC  for  

supply  the  load

RESUME 1

Government of Indonesia in year of 2012 released budget for construction 15

KWp Off Grid Solar (PV) generated at more than 100 locations spread out in

all around remote area

Based on previous calculation average energy production each location 15 KWp

Solar (PV) Off Grid System is 22,403 KWh per year , In year 2012 GOI been able to electricity 100 locations with

total electrical energy around 2,240,300 KWh per year

Development Solar (PV) system 15 KWp Off Grid on 100 locations , reduced carbon emission 878,893 kg/year

. . . . .

RESUME 2

Development 15 KWp Off Grid (stand alone) Solar (PV) system in Bungo

illuminated 118 houses in that Village

Average energy usage per day per house is 260 Wh

Can be used to illuminate the house until the children can do their home

work in the evening

to keep the system sustain, Energy Limiter installed in each house to limit/restrict energy usage in the houses
