- Q: Hi. I need to build a solar panel for a project. it should be able to light a 60 watt light bulb. also, it should be about 3x3 ft if it is 50% efficient. if anyone knows any websites or can help me, please answer! thanks.
- Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.
- Q: I'm thinking of having solar panels to generate electricity. The drawbacks are that I'm afraid if it needs repair, I won't be able to find anyone. Also I'm afraid that the roof is not very accessible. If it is a new house, should the roof have a roof hatch? What can make the system not work?
- Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.
- Q: I need to use solar panels to charge lead acid batteries in an off-grid application. I understand that solar panels have a open circuit maximum voltage and an maximum amperage under no resistance, and that one can optimize the power output by regulating the load (resistance). If so, is just connecting 2 -volt solar panels to a lead-acid battery inefficient? Are there devices that will maximize 2 volt output power (by varying the resistance)? Am I on the right track here? Thanks for any help.
- The answer is actually quite complicated, but if you're planning on building just a very small system, most likely, the panel will be small and weak. In this case, connecting a panel that is 8 volts open circuit directly to a lead-acid battery is probably the most efficient way to charge. There are charge controllers that you can buy, some of which actively track the maximum power point for charging your battery. Unfortunately, those controllers might eat 5 or 0 watts, just to get you another few percent of charging efficiency. If your panel is only 50 watts in the first place, you can see that this is not a good deal. If you're getting serious panels (clue: price $500 each), then you may very well benefit from a charge controller with MPPT (max power point tracking). Lead-acid, either a flooded cell like your car battery, or AGM, are the standard for solar energy storage. Lithium ion is better in many ways, being less sensitive to temperature, state of discharge, and they are also lighter. Charging them is also more straightforward with the right circuitry. The problem is, they cost like $500 per kWh, compared with less than a tenth that price for lead-acid.
- Q: Can solar panels be installed on refugee camps?
- Yes, solar panels can be installed on refugee camps. In fact, solar energy is often a viable and sustainable solution for providing electricity in these camps. Solar panels can be easily installed on rooftops or in open spaces, helping to meet the energy needs of refugees and improve their living conditions. Solar power can provide lighting, power for charging electronic devices, and even help run water pumps or refrigeration units. Its renewable nature and independence from the grid make it an ideal energy source for refugee camps, where access to reliable electricity is often limited.
- Q: Hi! I bought a Coleman 2 vdc cooler that pulls 9 amps. What size solar panel and amp-hour battery do I need? I only open it 3 times a day. It will hold about 3 gals of milk.
- If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK
- Q: Can solar panels be used in areas with high levels of air pollution?
- Yes, solar panels can still be used in areas with high levels of air pollution. While air pollution can reduce the efficiency of solar panels, they can still generate electricity even in polluted environments. However, regular cleaning and maintenance may be required to ensure optimal performance in such areas.
- Q: Can solar panels be used for powering a farm or agricultural operation?
- Yes, solar panels can be used to power a farm or agricultural operation. Solar energy can be harnessed through photovoltaic (PV) panels and converted into electricity to meet the energy demands of various agricultural activities such as irrigation, lighting, and running machinery. Solar power offers a sustainable and renewable energy source, reducing reliance on fossil fuels and minimizing operational costs for farmers. Additionally, solar panels can be installed on unused land, rooftops, or even integrated into greenhouses, making them highly adaptable for agricultural settings.
- Q: Im curious because I read about a boy who invented a 3d solar panel, using a pyramid he designed a solar panel that collects light more efficiently. Now I have a question. Why cant I design a solar panel that takes adventage of convex and concave mirror's and use a surface that collects light and then focus's the suns energy into a beam and take the beam into a chamber where the solar panels are sitting and surround them with mirrors as well, so any light not obsorbed by one particular spot is reflected to another area for reabsorbtion. I know solar panels dont absorb light but perhaps that will allow more light to create the effects it needs.

- Q: Can solar panels be installed on historical landmarks?
- Yes, solar panels can be installed on historical landmarks. However, it is important to ensure that the installation is done in a manner that preserves the historical integrity and aesthetic value of the landmark. This may involve careful planning, consultation with preservation experts, and using discreet or integrated solar panel designs.
- Q: Okay, me and my friends are going to fix up an old trailer that's out in the woods, we want something to be able to run small electric appliances off of, but it's to far to run power to. How can we make a good but cheap homemade solar panel that we could plug things into? The trailer is in more of a field so it gets plenty of sunlight! Thanks for any help! :)
- you cant make solar panels to generate electricity at home. A LOT of high tech equipment is needed. About the cheapest option is to use solar powered garden lights but that is all you'll get is a bit of light.(Google making solar panels) You should be able to make up a windmill powered generator though (but dont expect much power out of something you can make easily) Do some research yourself
