How much money is needed to build SOLAR ENERGY SYSTEM?

We Answered:

It depends.
A small one is $10 and one to keep a big house supplied with power can be more than $50000

Priscilla Said:

how much does it cost to buy a solar energy system for my roof?

We Answered:

Depends on a lot of different things, among other things how big of a space you want to power. The maintenance isn't much as there really isn't much to maintain with solar energy. The panels, inverters, batteries, etc come with warranties and the initial cost of the entire system can be reduced greatly by incentives from your utility and from NYS.

Again without specifics of what you want I really cant give you an accurate number. If its worth anything my Uncle used a company called Sun Electronics (based in Miami) for a big retro fit on his house in the Florida Keys. He had Solar and Wind installed so obviously his situation is a bit more advanced than yours, but he plugged in his solar calculation data into their website, then verified it against google and a few other sites and wound up getting a great price. He wound up referring them to my In Laws for a small solar system on their house outside of Chicago and they enjoyed using them as well.

Good Luck

Where and how i can take Solar energy system?

We Answered:

Want to make solar energy? Well technically, it's already being made by the sun... but you know what I mean. It can be fun to take the sun's energy and put it to good use. Perhaps you'd like to have some or all electrical appliances in your home be running on solar power? Of course, generating electricity isn't the only way to put the sunlight to work for us. It can also be used for heating, making hot water or even for cooking as well. Let's explore this a little...

Let's make solar energy work to heat water, as it can be pretty simple. First you need something to hold the water in, then something to focus the sun's light with, and then something within the water to then focus the sunlight upon. Let's say you have a clear acrylic cylinder - maybe about a foot wide, just for sake of illustration - the light can shine right through the clear water and heat it up... but not very well. If the cylinder is clear and the water is clear, then maybe 99% of the light is just flying through it and doing nothing to the water that it's passing through.

How can we make solar energy heat up the water then? Well, here's where we need a focuser - take some mylar or aluminum foil or other reflectant material, and cover about 1/3 to ½ of the cylinder with the shiny side in, so that the sunlight passing through the clear water will reflect off the inside of the back of the cylinder (in relation to the sun's light) and back through the water again. The curvature of the reflectant material covering the contour of the cylinder acts like a parabolic mirror with not only reflects, but focuses the light like a lens. However, the cylinder and the water are still both clear... now light is passing through and being reflected back, but we need something within to absorb the light and heat - a sort of solar heat collector, if you will.

Try a bit of anodized aluminum, colored black; maybe a bar, or maybe a tube or pipe. Have it run down the center of the water-filled cylinder where the reflector/focuser can reflect and focus upon the black, central piece. The black anodized aluminum rod will then heat up from the focused sunlight (and aluminum heats up fast) and transfer all that heat directly to the water through physical contact with it. Now you have a solar hot water heater! The sunlight passes through the cylinder and the water within and falls upon the reflector/focuser, and then it gets focused upon the central black anodized aluminum rod, witch gets very hot rather quickly and in turn heats up the water very efficiently.

How to design a solar energy system?

We Answered:

can be used to decrease or eliminate energy costs, reducing our impact on the environment and saving people money in the process. If you wish to design your own solar electric system, it pays to be prepared.

Step 1-Determine whether you will need to tie your solar electric system into the existing power grid or you wish to design it for use off the grid. This will depend on your precise location and how near you are to a power line.

Step 2-Calculate how much sun your area gets, and whether there are any obstructions which may cast shadows on your solar panels.

Step 3-Perform a power load analysis to determine what your electric needs will be. The table provided at SolarSense.com can help you calculate your requirements (see Resources below.)

Step 4-Determine the output of the panels you wish to use (based on their capacity and how much sun they will receive), the battery you have in mind, and the inverter your home will require.

Step 5-Compare your expected panel output with the amount of space your solar panels will require, and then compare that to the amount of space you have available. This will determine how much energy you can reasonably produce with your solar electric system, and should be incorporated into your design.

Step 6-Prepare a contingency for those times when the sun does not shine enough to produce adequate power. If you are on the grid, it will mean paying for electricity through the power company. If you are off the grid, it will mean using alternate forms of electric power such as generators.

Step 7-Choose your components based on what you require. These will vary widely depending upon your circumstances, but will include the solar panels themselves, mountings and means of securing the panels, conduits and wiring, an appropriate battery or generator, and an inverter to convert the panel's DC power to AC use.

How much money to build SOLAR PANEL (solar energy system)?

We Answered:

A small one to charge your cell phone is $10

One to keep a large house supplied with power, including all the associated equipment can be more than $50000

So the answer is "it depends"

Jenny Said:

Can any recommend a Solar Energy System that is truthfully viable in hard economic terms?

We Answered:

Since you have plenty of sun and need hot water all year round your home needs to conform to the design of the system.

The thermosiphon hot water solar system is the best, Requires no electricity and no moving parts. The tank must be above the solar collectors and the panel should have a lot of sun facing the southwest if you are in the Northern Hemisphere. The cost is dependent on the size of the system. Rule of thumb is 20 gals per person per day in solar tank size. Panel size is one square foot of panel for each two gallons of hot water if you are in the tropical zone.

what is the most cost effective solar energy system to install?

We Answered:

do you live in Arizona?
Alaska?
Vancouver?

how much electricity do you use?
for what appliances?

if i had to guess, of all the solar applications, a solar hot water heater would be the easiest and most cost efficient to install.
