# How to calculate the right number of solar panels and batteries

Navigation Info - Currently, many countries are looking for ways to overcome the pollution that pollutes the environment as a result of the manufacturing process of

**electrical energy**that uses coal, oil and fuel other mines that pollute the environment and are wasteful with non-renewable resources, this is a common problem for mankind, no wonder many are looking for ways to solve this problem, one of which is using solar power plants, where**solar panels**saves fuel usage which uses only natural sources of sunlight and does not cause pollution.How to calculate the right number of solar panels and batteries |

even though the electrical energy generated is still not satisfactory enough because to produce electrical energy or 1000 watts of power is considered to require sufficient capital to drain the bag plus it requires calculations for the right capacity so that it can last a long time, this is also what makes some people who just make (assemble) solar panels that do not reach 7 years have been damaged because they do not understand the correct calculation of the number of solar panels, batteries (batteries) and solar charger control.

### How to calculate the number of solar panels and batteries needed in the manufacture n solar energy

from the problems we describe above we can conclude that only many of the solar panel assemblers do not calculate the power consumption capacity with the need for batteries, solar panels and SCC (solar charger control) for the electrical power capacity, therefore this time we will discuss the formulation of the needs of solar panels and batteries ( battery) in the manufacture of a series of solar panels for solar power plants which are as follows:

#### Formula in Determining the Number of Solar Panels

solar panels are considered the lifeblood in the manufacture of solar power plants, so that requires precise calculations in determining the number of solar panels that are needed. required for the electricity consumption that will consume electrical energy from solar power plants.

So before we calculate the need for solar panels, we must first know the value of electricity consumption that we will consume from solar power plants, which formula is as follows:

**electric power consumption formula**

*electric power consumption formula = electric power x amount per piece x hours used*

*the formula for the total amount of electricity consumption = electric power consumption + electric power consumption+.....*

**formula**

**calculate the number of solar panels needed**

*the formula for the number of solar panels needed = (( the total amount of electricity consumption + ( </ i>*

*total power consumption x**40%**( power loss ))**: charger effective time per day ( 5 hours ) ) : wattpeak solar panels ( mostly sold 100wp/200wp in the market )***example questions :**

a house uses 5 lamps with electric power

**10 watts**with a usage time of**5 hours**per day and uses refrigerator with electric power**100 watts**one unit with a usage time of**24 hours**per day and also has a television with**20 watts**electrical power as much as 1 unit with**10 hours**per day, how much is**the total amount of electricity consumption**and how much**the total number of solar panels needed**?answer :

total power consumption

*electric power consumption formula =**electric power x amount per piece x hours of use < /i>*lights 10 watts x 5 pcs x 5 hours = 250 w

100 watts x 1 pc x 24 hours = 2400 w

20 watt television x 1 pc x 10 hours = 200 w

**the formula for the total amount of electricity consumption = electricity consumption + electricity consumption+.....**250 watts + 2400 + 200 = 2850 w

the total usage is 2850 watts so that we can find the number of solar panels needed which formula is as follows:

*formula for the number of solar panels needed = ( ( total number power consumption + (*

*total amount of electricity consumption x***< /div>**

*40%**( power loss )))**: charger effective time per day (5 hours) ): solar panel wattpeak (mostly sold 100wp/200wp in the market)*

( (2850 watts +( 2850 watts x 40% )) : 5 hours ) : 100wp = ((2850 w + 1140 w ) : 5 hours ) : 100wp = (3990 w : 5 hours ) : 100wp = 798 watts : 100wp = 7.98 solar panels so we round it into 8 panels sun

#### Formula in Determining the Number of Batteries (AKI)

for the above formula we have been able to determine the number of solar panels, namely 8 solar panels, now we will determine the number of batteries needed by the amount of power and solar panels in the problem above which uses the following formula:

#### battery formula for solar panels

*battery capacity formula : battery voltage ( Volts / V ) x battery amperage per hour ( Ampere hour / ah )*

*battery count formula = ( total power consumption + ( total power consumption x 5% ( power wasted ) ) : battery capacity*< /div>

**example questions :**

a house uses lamps with electric power 10 watts a total of 5 units with a usage time of 5 hours per day and use a refrigerator with electric power 100 watts one with a usage time 24 hours a day and also have a television with electric power 20 watts as much as 1 unit with usage 10 hours per day it is known the amount of power 2850 watts and solar panels needed 8 solar panels then how many bat erai ( AKI ) required where is the battery specification 12 v 100 ah ?

answer :

**battery capacity formula : battery voltage ( Volts / V ) x battery amperage per hour ( Ampere hour / ah )**

12 v x 100 ah = 1200 watts ( battery capacity )

*battery count formula = ( total power consumption + (*

*total power consumption x*

*5% ( power wasted ) ): battery capacity*

*( 2850 watts + ( 2850 w x 5% )) : 1200 watts = ( 2850 w + 142 w ) : 1200 w = 2992 w : 1200 w = We round 2.4 pieces into 3 batteries ( AKI )*

*Note: if you want to have a longer battery life, just multiply 2 ( for 2 times the endurance) 3 (**for 3 times the endurance) and so on.*

*for example you want to have a solar panel battery life more than the standard then you just multiply 2 examples*

*3 batteries x 2 = 6 batteries (batteries) with a capacity of 12 v 100 ah*

that's the formula for how to calculate the right number of solar panels and batteries, hopefully it will be useful. Next we will also discuss the capacity of the inventor and solar charger control (SCC) thank you have visited our blog.
