Photovoltaic power generation uses solar cells to convert light energy into electrical energy, and has the advantages of easy installation, environmental protection and no pollution.

Solar thermal power generation converts solar energy into heat energy through collectors, and then uses generator sets to convert heat energy into electrical energy.

These two power generation methods each have their own advantages and are suitable for different environments and scenarios.

Then there is energy storage technology.

Common ones include batteries, supercapacitors, and superconducting energy storage.

In addition, solar cells have a long lifespan.

Generally more than 25 years.

25 years?

That's totally unnecessary.

My buddy will retire at the age of 30 at the latest.

I am 22 years old now and will retire in another 8 years.

This is enough to save for retirement.

After listening to them, Zhuang Zhou thought they all seemed good and promising.

The only concern now is the amount of electricity generated and the price.

After Ural's explanation, Zhuang Zhou had a general understanding:

Solar power generation has an average efficiency of about 0.25-0.35 kilowatt-hours (kWh) per square meter per day.

Based on an average of 100 square meters per household, each household can generate approximately 2.5-3.5 kilowatt-hours of electricity per day.

If calculated based on a 5W LED light, the power consumption per hour is 5 watt-hours.

Other household appliances are not considered.

For home lighting alone, this is more than enough.

And then.

If you want to develop solar power generation in Chang'an, how much money do you need to invest?

After Ural made some inquiries, Zhuang Zhou had an idea.

The price is good.

Count the panels, controllers, batteries, inverters, cables and wiring accessories, and brackets.

A set of 10-kilowatt solar power generation equipment will cost about 80,000 to 100,000 yuan.

certainly.

This is calculated based on 100 square meters.

If the roof area is 200 square meters, the price is about 160,000 to 200,000 yuan.

During the Zhenguan period, there were about 200,000 households in Chang'an City.

This will be a huge market.

Even if we calculate it based on 5% of the market, there is still a market of 10,000 households.

Be good!

This is terrible!
