How can I make an electricity system?

We Answered:

You could use solar power, but you have to get a panel that is rated to drive the "air pump" max power requirement.

On the other hand, I believe most aquarium air pumps are AC pumps, so without you having more electrical experience, I would say this project is beyond you.

And on a final note, the fish do not need an "air pump", they need filtration, and water changes.
If you have a filter ( and I sure hope you do! ), then set it to agitate the surface of the water. Even a small amount of surface agitation will provide more than enough oxygen for the fish!. To find why water changes are necessary, ask on a fish forum.

You can however, use a DC motor connected to a solar panel with a small turbine (or similar) to agitate the water on the surface. That would be simple, cheap and safe!
Simply connect the solar panel to the DC motor and it will spin when it has enough light. A small solar panel should suffice too. The larger the solar panel, the faster the motor will spin.

How much do I need to set-up a solar powered apartment that uses about 500kl/hr of electricity monthly?

We Answered:

Your electric usage is about the same as mine. I could get a 4000 watt system and supply my needs. That size of a system would cost you in the USA about $26,000 installed unless you are dealing with a greedy dealer. The problem you have is you do not own your home so you will not beable to hook the system into the home.

Here is some info from a website based on 500 kWhrs usage and useing a 3.7 kwh system. Costing around 26K installed.

Your average monthly electricity bill is : $50.00

During the last 12 months you spent: $600.00

During the next 10 years you will spend: $7,285.20

During the next 30 years electricity will cost you : $32,057.68

What is the return on your investment (ROI)? ZERO !!!

Electric bills are not an investment, It is money down the drain.

Solar is a profitable investment

You can pay your Electric Company a total dollar amount of $32,057.68 and see a ZERO! return on your investment. Or you can invest money into a Solar Electric System and recive a HUGE ROI.

Based on the information provided, you would beable to save $5,819.66 for the home owner and $11,186.10 if you are a business owner. Plus you now own your own Elecctric Power Plant.
