Q:Wanting to add solar panels to my home?
Unless there has been some major breakthrough in solar panel efficiency - Forget it. I had looked at some utility interactive systems where the electricity generated by the solar panels went through a special inverter and into the electrical system of the house, any power you didn't use went backwards through the meter and into the grid. I figured that even if it was sunny every day, it would take about 20 years to break even on the system. That is, if I had invested $5,000 in a small system, to save $5,000 off the electric bill would take 20 years. If I had $5,000 to invest, this wouldnt be the place! It would take much more than 20 years of electrical savings to match even a modest investment. Then, don't forget what happens if 0 years from now the inverter or some of the panels fail and need replaced. Invest in fluorescent lights, maybe even LEDs. You will see a much quicker return on investment. Install more insulation, put in a heat-pump system. I appreciate you desire to save some energy, solar just isn't going to be worth doing, at least not yet.
Q:LED Lantern Charged via 6 volt solar panel?
If it has a 6 volt battery- is it marked 2 volts on an external plug? If so, there is a resistor inside to drop the potential the battery sees. The battery itself could be slipped out and recharged easily from your 6 volt panel. Just determine how much current (in Amps or Milliamps) the panel produces nominally and divide that into 4 and add one fourth of that length of time to make up for system losses. This will tell you how many hours it should charge assuming your starting voltage of the battery is above .5 volts. and the panel is at 3 volts potential or higher. So if your panel puts out amp at 0AM, you would charge for 5 hours. 4 divided by is 4 and one fourth of that is so 4 plus is 5. It is a little more involved than that, but as a rule of thumb. Also do not discharge tha lantern to the point of no light output. LEDs are efficient, but their current will add up. If it is suggest to be able to use the lantern for up to 8 hours on a charge, stick to that value. Lead acid batteries have best longevity when discharged only to 80 percent capacity. Once battery is charged- disconnect from charging source.
Q:why wont my solar panel make my dc motor work?
A 2V battery designed for a current max of 200mA, can turn on a 2W lamp. If you want to turn on a 2V 200Watt lamp, you need a bigger battery capable of providing 6 amps!! Similarly the solar panel you have can produce a voltage, but when connected to a motor, the voltage might drop to much lesser value!! So apart from voltage you also need to know current taken by motor. Further, motors have a habit of not starting, but once prodded (mechanically rotate the shaft with hand), they may run. If you are in that border area, give a turn to the motor and see.
Q:Want to power this with solar panels?
I do not know, but there is a house in Lafayette which was built with solar power. It was to have a solar system, so the contractor's first act was to put up a solar array on the property. It had battery backup, and was used to provide the electrical power during construction. during completion of the house the solar system was installed on the roof of the house.
Q:Solar Panel/Energy help?
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 hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 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 2000 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.
Q:When I make a solar panel what kind...?
First of all you seem to be talking about making a solar photovoltaic panel instead of a solar thermal panel. Most solar panels will produce DC electricity. Your house uses AC electricity. You can set up the solar photovoltaic panels to send their current to charge a battery bank and then you can tap into that battery bank and send the power to a voltage inverter to change the power to AC. The better inverters will do a better job of this. The system has to be matched and sized properly. If you are not familiar with electrical work you should have someone who is more knowledgeable help or do the work. Good luck with your project.

Q:2 Questions on Solar Panels?
The available energy is a function of several factors including insolation (sunpower) mounting angle, gathering area, type of cell and conversion efficiency.

Q:would the planet cool if covered in solar panels?
The opposite - they heat the Earth up. The ground underneath might be brown or green or sand. The solar panels are Black. They absorb more radiant energy. Solar electricity is energy and somewhere down the wire will produce heat. Solar's saving grace is that it has the same heating effect year after year. But greenhouse gasses have a cumulative effect. The excess gasses produced in year one are added to the gasses in year two, etc. For instance say the heating of soalr cells is 5 times (5s) that of greenhouse gasses (g). Year - Total Heating - 5s + g 2 - 5s + 2g 3 - 5s + 3g 4 - 5s + 4g 5 - 5s + 5g 6 - 5s + 6g 7 - 5s + 7g 8 - 5s + 8g 9 - 5s + 9g 0 - 5s + 0g etc... In 50 years you have 50 - 5s + 50g
