How can i build a solar power system that can supply all the basic appliances in our house?

We Answered:

Solar energy is horribly inefficient, it only converts appx 3-4% of the energy available it, it costs a fortune to. i would suggest using a different form of renewable source. use solar energy to heat you water (very simple non-electrical system - black hose-piping within a black box - supprisingly effective for what you may thtink it is, this also saves money on electricity.

You could convert your central heating to a heat engine system (loads of info online about it) - expensive outlay but unlike solar cells very efficient with it.

other than that common household electrical requirements nowadays are sickening and really need the national grid juice to power it. If you have a river/stream by your house tha can easily be harnessed to power all your lights, refridgerator and basic amenities ... - however how many ppl actually have a stream... LUCKY BAS***D'S!

Good luck with What ever you do, any one cutting down their fuel useage is good!!!

Which president had the most efficient up to date solar power system installed on the white house?

Why bother to ask if you're going to answer it yourself ??

How does the solar power system run with electrical energy?

We Answered:

There are several different types of solar panels to capture solar energy for homes. There are also a number of ways to concentrate solar energy for use in power stations.

Solar panels can be photovoltaic and produce electricity. By combining the panels in a series you are electrically concentrating the energy.

A different type of Solar panels can also capture the suns thermal (heat) energy which is used for heat, hot water, and air conditioning. Often these systems contain air or hot water that is heated and stored (concentrated) in a tank or other storage facility.

For concentrating solar power (thermal) that is then used to produce electricity some of the systems are called:

Solar power tower (using heliostats focused on a central tower)
Solar parabolic trough collector
Solar fresnel lens (using flat mirrors and similar to parabolic trough)
Solar parabolic dish collector (with a stirling engine)
Solar chimney (also sometimes called a solar tower)
Solar pond

How does a solar power system for a house work?

We Answered:

Photovoltaic solar panels (Called modules in the trade) are mounted so they see direct sunlight. They generate DC electricity. The DC is converted to AC by inverters. Some DC can be use to maintain a charge on batteries. Where permitted the homeowner can feed excess power to the utility, and get it back at night when the solar system is not generating.

Batteries are needed if the system is not on the utility grid, and can be useful where utility outages are frequent, or have an impact on the user.

Earl Said:

Is it possible to make a solar power system myself...??

We Answered:

Yes, but unless you are an electrician you should hire one to do it. The power company will also need to be involved

There are two main ways to do this.

One is a battery system where you go completely off the grid. However the batteries don't last forever.

Two, the power company becomes your battery, as in you sell them what you generate as extra power and buy it when your panels to not generate enough.

What regulations are there for importing a solar power system?

We Answered:

I would venture to say that importing a solar power system is going to be cost prohibitive considering the large manufacturing base in the United States.

However, since the technology is commonly available on the market today, you should be able to import most of the equipment without tariffs. The company sending it to you is expected to pay those costs upfront for you.
