Steemit friends, how are you all? Hope you are all well by God's grace. I am also fine by the grace of God. Today, I will write about the Solar Project in Week 2 of the Electrical Learning Part. Hope everyone will benefit from my post.

Last week, I showed the generation and use of DC electricity from solar energy in the DC Solar Project. Today, I will show you how to use AC power by generating electricity from the renewable energy sun. So, without wasting time, let's start.
I will first explain the difference between AC and DC solar power.
AC Solar Electricity | DC Solar Electricity |

AC solar electricity: The heat energy received from the sun is converted into DC electricity, but the loads in our house (lights, fans) are powered by AC electricity. So when this DC electricity is converted into AC electricity in a system, it is called AC solar electricity.
DC Solar Electricity: DC solar electricity is the electricity stored in the battery by converting the thermal energy received from the sun. The electricity obtained from the battery is converted into AC electricity by a system, which I will write in my post today.
AC solar power generation costs a little more than DC solar power generation.
DC solar power generation cost is less than AC solar power generation cost.
Home loads can be run easily with AC solar power. A new light and fan is not required.
Household loads cannot be run with DC solar power. New DC lights and fans have to be installed.
I think my house has three lights of 20 watts and three fans of 70 watts. Then, I will calculate how much solar power project I need.
Load Name | Quantity | Watt | Total Watt |
---|---|---|---|
AC Light | 3 | 20W | 60 W |
AC Fan | 3 | 70W | 210W |
From the above chart, I understand that the total load in my house is 270 watts. So, I will do a 300-watt AC solar project in my home. Below, I have described the required materials for the 300-watt AC Solar Project.
Material Name | Quantity | Range | Possible Price |
---|---|---|---|
Solar Panel | 3 Pcs | 100 W | 833 Steem |
Charger Controller | 1 pcs | 50 A | 83 Steem |
Battery/ESS | 3 Pcs | 12 V, 300 AH | 1666 Steem |
There is no need to purchase lights or fans separately for AC solar power. Our house will run with house lights or fans. The longer the battery here, the longer the backup time. It will be powered directly by sunlight during the day and run on battery backup at night.

First, after the sunlight falls on the solar panel, the panel will convert the thermal energy into electrical energy. Then, the electricity will be stored in the battery through the charge controller. The function of the charge controller is to signal when there is a problem and charge the battery at a specified rate. Then, AC power is converted from battery to DC power inverter. Here, the function of the inverter is to convert DC power into AC power. Then, the AC power obtained from the inverter is given to loads of lights, fans, air conditioners, etc., in our house. This is how an AC solar project works.
Today, I have shown the AC solar power generation process and home load driving. Next week, I will show AC solar power 220/440 volt and 33kv,132kv system. These solar projects are used in big factories and powerhouses.
