Electrathon Car battery Regeneration?

solarkit — Sun, 27 Jun 2010 18:12:27 +0000

Our school has an electrathon car that we race. I am the driver this year (smirk ear to ear). I want to incorporate brakes that regenerate the battery when it is coasting. The concept is that we have 2 batteries and we race around a track and see who can complete the most laps in 1 hour. Only 2 batteries are allowed and they can’t be swapped. We need to find a way to regenerate power without creating much drag. Other ideas have included solar panels and windmills on the car, but I have asked around other schools in the area, and one school does this brake regeneration. I wouldn’t ask the world on here, but they are unwilling to share their secret.

Also, if you can help by telling any modifications we can do to increase the speed, it would be amazing. Here is a link to the car we have:

Solar Energy Companies In Miami,FL, Please HELP!!?

solarkit — Sat, 19 Jun 2010 18:05:29 +0000

Well this is simple my energy bill is killing me and I have made up my mind, I’M GOING SOLAR!!!

I’m looking for a solar company in Miami, Florida that sells the panels, batteries, cables, everything the whole kit.
It would be great if they export world-wide.
I was also wondering if there’s a chart like if your house is this big you need this many pannels and stuff.
Thank for your help.
Uhhhm hello? I didn’t ask for reason not to buy solar but where I can buy them just answer the question, or not!!! I live where it’s almost a mircale if we see some rain, at least one day per year, OK!!!
We don’t even have winter and it’s 32 degreas celcius everyday!!

Solar AA battery charger with meter charges 4 batteries

solarkit — Tue, 08 Jun 2010 16:52:35 +0000

This is a short demonstration of our solar AA charger with meter. It can charge up to 4 AA batteries using the clean free energy of the sun. We carry many other solar products.

What kind of battery do I need?

solarkit — Sat, 05 Jun 2010 18:01:19 +0000

I just got my first solar-panel starter kit, and I want to use it for my light, so I have to have a battery for it.
The panels are 12 volt, 65 watt.
What kind of battery/batteries, and how many lights can I have on it?
My mistake, it is 60 watt, not 65, and there are 4 panels, I do not know if they are 60 what each, or total.
IGNORE EVERYTHING BEFORE THIS…..
Ok. here are the facts.
4 15 watt solar panels, for a total of 60 watts.
1 200 watt inverter.
1 regulator/controller
I also have 1 75 watt inverter, and 1 800 watt inverter that did not come with the kit.
The only things on them will be lights, and 1 outlet when the power is out, the outlet will be on the main line when we do have power, the lights will be on solar all the time.
What kind of batteries can I use, and how many lights can I have on it?
What kind of batteries do I need, how many, and how many lights can I have on it?
I am also open to ideas on how to hook everything up. I think I know how to do it, but others have already done this sort of stuff, so it would be smart to get ideas from them.

When will solar and wind power be affordable to the average home owner?

solarkit — Tue, 25 May 2010 18:03:42 +0000

I have been doing some research on solar panel and wind turbine systems. The pricing is crazy. For a 10Kw solar grid tie kit system is between ,000 and ,000. If you install batteries add ,000-,000. 10Kw will only power a small to medium home without electric heat. Using my electric usage and info from my local electric company payback is 60 years for solar and 361 years for wind. This is unexceptionable. The manufactures of the solar and wind are gouging the consumers. They are using the excuse of supply and demand for the high cost. When demand goes up so will mass production and the price will go down. This is true, but they are making a huge profit on what they are making now. Some items are in the 3000% markup range. Are the power companies keeping the price up so their profits don’t suffer? My local electric supplier has an "ENERGY PARK" that you can go see solar and wind power in action and check out real time data online. They have a 4Kw solar array installed and claim it cost ,378 installed and a 2.5Kw wind turbine that cost about ,000 installed. I think they are giving false numbers to consumers so you won’t go green. I was able to find a 3.5Kw kit online for ,000. This doesn’t include any type of mounting materials. You can add 0-,200 for these materials. An installer will will charge you ,000-,000 to install it. For the sake of argument lets say this will cost you ,000 to install but still way out of line for you and me to install. That is a far cry from the ,000 the power company claims. The power companies don’t want you to make your own electric. They are keeping the cost high so they will still make money off you. A 210w panel sells for around 0. They probably manufacture it for under . The cost needs to be 0-0 to the consumer to make it affordable to the average home owner. 50 210w panels make a 10Kw system. That would be ,000 not ,000. The manufactures are raping us and the power companies are helping them to keep prices high. When will we get the technology at a proper cost? Let me know what you think.
In response to the first 5 answers, Yes, if demand increases so will mass production and thus supply will increase and this will drive the price down. I looked into panels from China. From what I was able to find panels sell for {content}.17-{content}.45 per watt. In the U.S. they sell for .00-.00 per watt. Manufactures in the U.S. have lobbied for a higher tariff on solar products that makes them impractical to import on mass. These companies want to keep the price high so their profits stay high, and the power companies do not want you to produce all your own power. That would put them out of business.
In response to Steve R, You need to do more research before you post another retarded comment like that. Air "DOES" have mass (just not very dense). When air is in motion it is called "WIND". This motion creates energy. Have you ever heard of a "tornado"? Get your facts together next time.

Help with getting low amp reading with my solar panel array?

solarkit — Sun, 09 May 2010 22:51:32 +0000

I had my solar panel set up for a couple months now and just started to monitor the power output. Right now I have a 90 watt harbor freight kit, and 2 80 watt mono and 2 80 watt poly panels. All are wired in parallel so it should add to about 410 watts at around 20 volts right? I know voltage drop for battery bank after charge controller. So it converts it down to 13 volts. I have an amp meter wired in series before the charge controller and at peek time I only see it reach 14 amp. 14 x 13 volts is 182 watts I am only getting out of the panels. So I cam losing almost 60% of my potential power output from the panels!!!! Why is that? I thought that the amps do not change only the voltage drop for the batteries, so my meter should read almost 20 amps. Which would be 20 x 13 volts = 260 watts output from panels. That is only around 40% of power loss. I am so confused and not happy with the results I am reading here with the amount of money I spent for all of this. Thanks for every ones time and help.

What type of power storage system should I get?

solarkit — Wed, 05 May 2010 06:17:42 +0000

I’m getting a 45 W solar panel kit ( http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=90599 ) for a greenhouse. I want to have a small heater in case of freezing temperatures and a few lights. I’m in the Willamette Valley, Oregon.

I wanted to know approximately what kind of batteries and how many I should get.

Does anyone know about solar power?

solarkit — Sun, 02 May 2010 11:42:47 +0000

I really need to know what size battery I need to use with a 60 watt solar panel kit. Also how many batteries I will need. I will be using this kit with an old self contained camper. Thanks
