FAQ

In some countries where electric generation is low, they are not available easily.

Supply and demand, my friend.

Hi, I bought 50 6X6 inch solar cells, I also bought a 40 amp diode, I still need to buy a battery, and inverter and a voltage controller, could you tell answer me the following questions:) I would like t build a small panel at first, (may be 0 X 0 inch), with that I would like (or at least to try) to power my laptop for the hole day, so I wont receive a very high amperage, yet, all the inverters I saw at e-bay are rated over 400 amp, if I buy a 400 amp inverter, can I use it with such a small amperage?2) what about buying a small car inverter, will it work?3) suggestion about the battery and the voltage controller will be kindly appreciated.Thanks

I'm guessing that each of those solar cells is just 0.5 volt at max power, so if you make a 2-inch square panel, you will get 2 volts - not enough for the inverter. A car inverter is notoriously inefficient, but it would work if you connect it to a 2-volt battery. You cannot generally connect such an inverter to solar panels alone. The battery supplies the peak current that the inverter needs, and the panel charges the battery. To charge a 2-volt battery, you will want 36 cells, generally, which give you an 8-volt panel. You can buy an inexpensive charge controller somewhere. If your laptop will run off 2 volts directly, you can skip the inverter and be much more efficient. Or if the laptop runs of (say) 9 volts, you can use about 40 cells to get 20 volts, get the proper power plug from Radio Shack, and plug the panel directly into the laptop.

The battery is 9ah and the solar panel is 20w

Buy the proper charger or get a degree. Don't screw with making a charger for a lead acid battery of you don't know what you are doing. You could get hurt. You need a hell of a lot more than just a regulator.

Yes, solar panels can be installed on a pergola or shade structure. In fact, this is a popular option for homeowners who want to maximize their solar energy production while also providing additional shade and functionality to their outdoor space. The pergola or shade structure can serve as a sturdy and aesthetically pleasing platform to mount the solar panels, allowing for dual benefits of energy generation and outdoor comfort.

how to make a solar panel without buying any kit?Any things at home that can be used for solar panels(what are they?)procedures how to make a solar panel

There are 2 kinds of solar cell/panel. Electrical and thermal. Passive thermal is the easiest. It can be made with clear glass bottles or jars. The bottles or jars must first be cleaned and sterilized to prevent the growth of algae or bacteria. Fill these about 90% full with water that has tsp of chlorine bleach per gallon. Put the caps or lids on tight. Seal with hot melt or other waterproof glue like RTV silicone. Arrange these in an array. You can use cement or just build a wood frame. Even simpler is just to put the bottles on a board or window sill. Place this in a sunny spot. The water will be heated by the solar radiation and will stay warm several hours after the sun is no longer shining on them. A an active thermal cell is different. For this you need a medium to heat. Silicon oil is often used but your could just use water. You need a collector, reservoir, heat sink, and circulating pump. These must be arranged in a manner so that the medium (water) is pumped to the collector where it is heated. It passes through the heat sink to transfer the heat and then returns to the reservoir. To make an electrical panel you can buy components. Photovoltaic cells and the components to mount them, wire them and then change the current generated into a type and voltage you can use.

how would you build a solar panel

As a sandwich. Glass Space /4 inch Glass Space with copper radiator painted flat black. Box made of wood. with the inside painted black. Insulate the back side. Use water with RV antifreese. Circulate water through with a small pump. Face it toward the sun. Thermal water solar Panel.

The amount of energy that solar panels can generate depends on various factors such as the size and efficiency of the panels, the amount of sunlight received, and the geographical location. On average, a residential solar panel system can generate between 10 to 20 kilowatt-hours (kWh) of electricity per day. However, larger commercial or utility-scale solar installations can generate significantly more energy, sometimes even in the megawatt range.

I was having a discussion with a friends about solar panels.He says that if there is a solar panel (sp) on the ground and a solar panel (sp2) high in the atmosphere (in the stratosphere) the difference in power output between sp and sp2 negligible. I said that there would be a large difference in power output because sp has all of the atmosphere to block the suns rays and sp2 has very little atmosphere because it is very high up (in the stratosphere) therefore more sun can get to the panel and more power is produced.who is correct? many thanks in advance, please leave sources if possible, for validity.

There will be a difference (44%, see below) but not a large one. The atmosphere is transparent to the wavelengths used by the solar panel. But no clouds, and a lot more hours of sunlight. wikipedia: Space-based solar power (SBSP) (or historically space solar power- SSP) is a system for the collection of solar power in space, for use on Earth. SBSP differs from the usual method of solar power collection in that the solar panels used to collect the energy would reside on a satellite in orbit, often referred to as a solar power satellite (SPS), rather than on Earth's surface. In space, collection of the Sun's energy is unaffected by the day/night cycle, weather, seasons, or the filtering effect of Earth's atmospheric gases.
