CALCULATE SOLAR PANELS (PV modules)
1. Calculate the total power consumption (watt-hour) of all equipment that the solar system must deliver every day
Calculate the total Watt-hour use per day of each device. Plus all back we have the total Watt-hour load use every day.
For example: is television there is consumption 80W, use medium 8 g per day, the number of Watts-hour use per day is 80 x 8 = 640 wh. Every computer for each such device and then all will have the total Watt-hour of all equipment that the solar system is provided.
2. Calculate the number of Watts-hour solar panels must provide for full download every day
Due to the loss in the system, the number of Watts-hour of solar panels to supply the higher total Watt-hour of load. Experiments showed that approximately 1.3 times higher.
The number of Watts-hour solar panels (PV modules) = 1.3 x total Watt-hour load used.
In the above example, the watt-hour solar panels is 640 x 1.3 = 832 wh
3. Calculate the size solar panels need to use
To calculate the size of the solar panels need to use our computer, Watt-peak (Wp) needs of the solar panels. The amount of Wp that solar cells generate back depending on the climate of each region of the world. With solar panels but put in place, the level of absorbed energy will differ when put it elsewhere. To correct design, one must measure the survey speed of absorbing solar radiation in each region of the months of the year and give an average number system called "panel generation factor", meaning radiation absorption coefficient of solar batteries. "Panel generation factor" this is analysis of absorption efficiency (collection efficiency) and solar radiation (solar radiation), unit of it is (kWh/m2/day).
For example solar absorption levels at 1 location is 5 kWh/m2/day, we take the total Watt-hour solar panels divided by 5, we will have a total of Wp of solar panels.
In the above example, the watt-peak of the solar panels is: 832/5 = 166 Wp
Every REPORTER that we use are the Wp parameters of it, taking the total number of Wp needs of solar panels to the Wp parameters of it, we will get the number of solar panels to be used.
In the above example if using solar panel 85 wp number panel needs to have is: 166/85 # 2 sheets
Results on only for me to know the minimum number the number of solar panels needed to use. The more solar panel system will work better, the lifespan of the battery is higher. If there are fewer solar cells, the system will lack power in the shady day, withdraw the exhausted battery and so will do battery lifetime. If the design too much solar batteries, the high cost of the system, beyond the budget allows, sometimes unnecessary.
So, how much solar cell design, and depending on the backup of the system. Such a system of electricity from solar Batteries were redundant on 4, (called autonomy day, is the day without sunshine for solar cells produce electricity), the required amount of battery to increase over and pull in to increase the number of solar cells. Then use the battery problem types would be optimal, is appropriate for each geographical region has different weather. All require the design to do the experts have many years of design experience for the solar system in the region.
Also, when we had a total of solar panels is not necessarily the next pairing all the sheets together which can transplant them into their combining serial and parallel combinations, do one or more of the solar controller. The work has a mutual interaction to designing the system battery and solar charger below.
CALCULATE THE ACCUMULATOR (BATTERY)
Battery for solar power systems is the kind of deep-cycle. This type allows to discharge to the average rate was very low and allows fast refill. It has the ability to load discharge many times (many cycle) which is not broken inside, therefore quite durable, high longevity.
First we calculate the amount of the average system ac-attributed to the whole system. Capacity of battery to be used for solar system is battery power supply enough capacity for the on reserve (autonomy day) when the solar panels do not produce electricity.
Battery capacity calculated as follows:
-The performance of the battery is only about 85% of the load, so divide the number of Wh consumed with 0.85 I have Wh of the battery
-With deep discharge level (Deep of Discharge DOD) is 0.6, we divide the number of Wh battery for 0.6 will have a capacity of battery

Results on the minimum battery capacity for us for solar system has no backup. When the solar system has a number of on reserve (autonomy day) we have to multiply the battery capacity for the number of autonomy-day to have the number of batteries needed for the system.
When voltage V and a capacity of acquy Ah, we can choose acquy and calculate how to pair them together for optimum, and must pay attention to computer backup of the entire system. Example 1 the ac system-12V/12V/200AH range 5 transplant 1000AH parallel will have a higher safety level 1 12V/1000AH ranges, if some ac-broken rules I still fish

CALCULATION solar panels (PV modules) 1. Calculate the total power consumption (watt-hour) of all the devices that the system must provide a daily solar Calculate total Watt-hour daily use of each device. Plus all together we have a total of Watt-hour full load daily use. For example, television is loaded power consumption is 80W, the average use of 8 g per day, the number of watt-hour of use per day is 80 x 8 = 640 wh. Calculation for each such device and then add all of the watt-hour will have a total of all devices that provide solar system. 2. Watt-hour calculate the number of solar panels to provide full download every day Due losses in the system, the Watt-hour of solar panels to provide higher total Watt-hour of full load. Experiment shows about 1.3 times higher. The Watt-hour of solar panels (PV modules) = 1.3 x the total Watt-hour full-load use. For example, the watt-hour above the solar panels 640 x 1.3 = sun is 832 wh 3. Calculating the size of solar panels should useto calculate the size of the solar panels need to use, we calculate the Watt-peak (Wp) required by solar panels. Wp solar output that generated depending on the climate of each region in the world. 1 solar panels together but put in place, the level of energy absorbed is different from putting it somewhere else. To correct design, one must surveying absorption of solar radiation in each region throughout the year and give an average coefficient called "panel generation factor", roughly translated as absorption coefficients of solar radiation. Coefficient "panel generation factor" is the product of the absorption efficiency (collection efficiency) and the solar radiation (solar radiation), its unit is (kWh / m2 / day). For example, the solar energy absorbed at one location is 5 kWh / m2 / day, we take the total Watt-hour of solar panels divided by 5, we will have a total of Wp solar panels.for example above, watt-peak of solar panels is: 832/5 = 166 Wp PV Every feature we use Wp its parameters, taking the total number of required Wp solar panels divided by its parameters would Wp get the number of solar panels needed. for example, if used in the solar panel 85 Wp panels required number is: 166/85 # 2 plate above result tells us only the minimum number of number plates solar battery use. The more solar panels, the system will work better, the battery life will be higher. If there is less solar cell system will power shortage in the days shade, draw and so exhausted battery will decrease battery life. If the design is too many solar cells are made of high system costs, exceeding the budget allowed, sometimes unnecessarily. So how much designers solar cells depends on the redundancy of the system . For example a power system from solar battery has a standby 4 days, (called autonomy day, is the day without sunshine for solar power production), is required to increase the amount of battery and pull according to increase the number of solar cells. Then the problem battery type is optimal, as appropriate for each geographical region has different weather. All require designers to by experts with experience designing many years for solar systems in the region. Also, when we had a total of solar panels are not necessarily paired to all panels together which can transplant them into the consortium combines serial and parallel, by one or more solar charge controller. These tasks can interact with each other to design a solar system battery and charger system below. CALCULATION OF BATTERIES (BATTERY) Battery systems for solar power is kind of deep-cycle. This type allows for discharge to very low levels of average and allows quick refill. It is capable of charging and discharging many times (lots of cycle) without broken inside, so pretty durable, long life. First we calculate the average size of ac-regulation system for the entire system.Battery capacity needed for solar system is enough capacity battery provides backup power for days (autonomy day) when the solar panels do not produce electricity. We calculate battery capacity as follows: - Performance the battery capacity is only about 85% so divide the number of loaded consumed Wh 0.85 Wh of battery we - with deep discharge (DOD deep of discharge) is 0.6, divide the number of battery to 0.6 Wh will have capacity battery crystal-attempt-he-thong-dien-nang-luong-mat-troitinh-attempt-he-thong-dien-nang-luong-mat-troi-1 result for us on the minimum battery capacity for solar systems without preventive. When the solar system has redundancy dates (autonomy day) we must multiply the capacity for autonomy-day battery for a number of battery required for the system. Once you have a voltage V and the average Ah battery capacity, we can selection of battery and calculate how to stitch them together so that the most optimal, and must pay attention to the redundancy of the system. Example 1 ac-regulation system 12V / 12V 1000AH 5 blocks puzzle / 200Ah parallel will have a higher safety level 1 block 12V / 1000AH, if 1 couple ac-regulation fails, I still fish
