You need to do research. First find out how much power your items are going to be drawing. Next, you have to research a bit on solar cells. What you are mostly interested in is efficiency and the surface area you are going to be able to cover with them. You will use this information in conjunction with the amount of time you believe your solar cells with be exposed to the sun and the amount of energy the sun will provide to that surface area to determine the efficiency of the solar panel you need. There’s more to it, but since you are asking for help on yahoo, that should do.

Good place to search is in homepower and solar today magazines both have frequent reviews on inverters and both also are online. I have heard nothing but good things about sunnyboy brand.

The initial hit to the pocket book is still staggering but is going down. Eventually it will pay for itself. Tv’s computers use alot of electric if left on all the time. As well as all the lights on in the house hope this info helps you :0)

For a perfect GREEN Home:
install solar panels that can deliver just enough for your consumption. Also compliment it with a wind energy set up, connected to it : 1- 2.5 lacs. But it is almost once in a lifetime investment [of course the batteries are to be replaced every 5-6 yrs, now their costs vary a lot, but are sure to come down !. If you get the wind mills hooked to your gym/ pedal/walk system, you save a lot more. We are lucky to have good sunlight & winds too , most of the year. Recently Germany has been using Solar to make as much as 20 % of its annual use

ssadmin answers:

The added value is proportional the annual electricity generation of the solar system. A typical 3 kW system can generate 5400 KW-h every year, multiply it by the price of 1 KW-h where you live.
If you are deterred by the “ugliness”, you may opt to install solar shingles that fit seamlessly into the roofing of the house

Sarcasm: A literary device for identifying the stupid.

ssadmin answers:

The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions.
A computer and monitor use about 400 Watts. Not per hour – watts is Volts * Amps and a measure of Power. In 1 hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy.

To power a lab of 10 computers you will need 10* 400 = 4000 Watts.
To run this from solar panels through the day only you would need a 4000 Watt panel.
Except – its cloudy, the sun is in the wrong place – many factors reduce the output.

To be reasonably safe you would need about a 12000 Watt panel.
Then you would need
batteries to store power through dull periods AND
a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.

To become a qualified solar installer, it is recommended that you take an accredited course. You can see a list of places that offer these courses at http://irecusa.org/irec-programs/ispq-training-accreditation/ispq-awardees/.

The ultimate goal for installers is to get NABCEP certification. These classes can help acheive that.

You really cant, it would take large ammounts of space and thousands of dollars in solar panels to even come close to a fraction of what a house uses. Also solar panels create DC power which would have to be converted to AC in a dynamo or inverter… And there is always losses do resistance etc.

Also solar panels don’t last forever, they have to be replaced every few years depending on the quality so in the end it’s cheaper to stay with your local utility provider….no I don’t work for one…

ssadmin answers:

In some places, the electric companies charge a very low rate, and it is more economical to simply use that rather than invest large sums up front.

In other areas, it would be more economical in the long run to use solar panels, but in this economy, companies simply don’t have the capital to invest.

As a homeowner, would you rather pay $10,000-20,000 up front for solar energy, or would you rather pay $80/month??

ssadmin answers:

Everything has to do with physics at some level.

Solar panels produce energy. They use energy from the sun ( light) and convert it to a flow of electrons ( electricity). The question about “is it worth the money” unfortunately is not a question of physics, it’s a financial question. I suppose you could try and compare the energy that goes into producing the solar cell with the energy that the cell is expected to produce. If you can accurately compare those two energies then you might have some physics data for your question but that information would be very hard to quantify.

ssadmin answers:

Well, 1 HP is 750 Watts but a DC motor is typically 90% efficient though there are some as efficient as 95%. Also it’s customary to design electrical circuits to operate at 80% load therefore you would want about 1,041 Watts to run it directly from the solar panels during Sunshine hours.

Perhaps you should look at the duty cycle of the compressor to try and decide if banking the power on batteries would be sufficient. Problem there is that lead acid batteries are only 50% efficient at charging and have a 1% per day loss rate, still if your motor only ran for an hour a day and you had 8 hours of usable sunshine per day the you may be able to get by with a 260 Watt panel and maybe three 60 AH batteries.

Maybe you should hook up a power meter and measure what you’re actually using both in peak watts and in cumulative watt hours during the day. Note you’ll need a higher voltage to charge the batteries, a float charge would be 13.5 V, a bulk charge would be about 14.4 V. You’ll need a charge controller with batteries and a voltage regulator without batteries. Fairly simple devices that an Engineering student could sketch out with a few power transistors

ssadmin answers:

There’s a couple of issues, the first being what you’re allowed to have. In many neighborhoods a wind turbine would be out of the question because they make a lot of noise and they sand out visually hence it may violate the neighborhood’s deed restrictions. But if you are allowed to have a wind turbine, they are much less expensive then Solar Photo-Voltaic and with a grid tie in, you wouldn’t need an expensive battery bank.

The second is what are your energy needs? The majority of the energy used by a household is for hot water, residential heating and or air-conditioning. All three of these could be met with Solar thermal collectors at a fraction of the cost of Solar Photo-Voltaic. The Solar air-conditioning would require an absorption chiller to turn the heat into chilled water for the air-conditioning and would most likely work best with evacuated tube solar thermal collectors. With the exception of evacuated tube, solar thermal collectors are sufficiently low tech that you could build your own collectors. Solar thermal is in fact more efficient than current Photo-Voltaic as the current Photo-Voltaic cells only respond to very specific wavelengths of light. If you meet the majority of your energy needs with inexpensive low tech solar thermal collectors, then you can greatly reduce the size of your Photo-Voltaic system.

I would say that you should try and meet most of your energy needs with Solar Thermal collectors and if your neighborhood allows, have a small wind turbine with a grid tie in for electricity. If you’re not allowed to have a wind turbine then a small PV system, again with grid tie in would suffice.

No, home-made goods do not qualify since they don’t have the manufacturer’s EPA certification.

Advertise in solar magazines like Home Power (USA), another one is Solar Today, I think

ssadmin answers:

There is a program in San Francisco to provide free solar power to some underprivileged homes, but that is on a very limited basis. Obviously, demand far outstrips supply.

I think Berkeley and some other cities may provide loans so that someone can buy a solar system. The payments on the loans may be less than the savings on electric bills, so in that sense, someone could switch over to some solar for “free”.

Some cities in the USA are still rebating to the tune of $5 a watt, so if you’re lucky enough to live in one of those areas, your panels may indeed be free. But for the US in general, no.

ssadmin answers:

Depending on how many you are going to use–if you have more than enough to run your home — you can sell the rest to the elec co. I seen on tv where folks had roof panels and his elec bill sometimes paid him–mostly was 0-30 $ a mo he had approx 12 panels
