Solar Electrical Learning Part-18||Week-18||800-watt, 1000VA Inverter solar panel load calculation and whole package purchase calculation.

Steemian Friends,
Today, I will write Solar Electrical Learning Part-18. Today, I will buy 800-watt, 1000-VA inverter solar panels from the market. Today, I will show the load calculation of solar panels so that everyone can read my post and buy solar from the market. Today, I will cover purchasing solar, and in the next post, I will cover solar installation.

I am going to purchase a solar package for my office colleague. I first calculated the load of my office colleague's house. Then, I described the two solar packages to my office colleague and asked about his budget for solar purchases.

Solar Shop

I calculate a solar package to power four 100-watt fans and three 30-watt lights. So, according to my calculation, for a 1004=400W fan and a 303=90W lamp, the total load is 490 W.

When packaging solar panels

Then, I take the 800-watt solar panel as an extra from the total load. I will buy a solar panel with a slightly higher wattage than the load because I can increase the load later if I want. I am mentioning the solar package with the price below.

Solar panel	250 watt	2 pcs	500 watt	17,000 Taka(Local)	392 Steem
Solar panel	150 watt	2 pcs	300 watt	10,200 Taka(Local)	235 Steem

Purchased solar panels

I wanted to purchase four panels of 200 watts, but because of the hot weather in our country, many solar panels are being sold. So, at this moment, I am not getting a 200-watt solar panel in the market. I was forced to purchase two 250-watt and two 150-watt panels.

When checking the hybrid inverter

With a solar hybrid inverter, the battery will be automatically charged and load supplied by sunlight. If there is no sunlight, the battery will be charged from the automatic power supply. I don't have to do anything with my hands here. All automatic hybrid inverters will work.

I have a hybrid inverter

I suggested purchasing a 200 AH lithium battery. However, the cost of lithium batteries is high in our country and is not commonly available. So, I offered to buy a battery of 130 AH for now. I suggest increasing the battery as a backup later.

Then, I send the whole solar package home in a van from the market. My electrical team and I will do the installation with a date. I will show the solar installation in the next post.

Solar packages are purchased and taken in vans

In our country, people are less interested in solar because they do not know how to buy and calculate the load. I have made this post today to highlight my post on load calculation through solar and how to generate electricity efficiently and economically through solar. I hope everyone will get some idea about solar packages by reading my post.

Solar Charger Controller

Today's 800-watt solar package is slightly more expensive because I used a solar inverter. If only the charger controller had been used, the cost of the solar package would have been reduced. But if the charger controller is not working, I will have to purchase the solar DC light and DC fan separately. Through today's package, our country's electricity and solar electricity will be produced, i.e., AC electricity. This way, I don't have to do separate house wiring.
