Design and Construction of Solar Power-Based Lighting System.

Solar power is big these days, from power plants to rooftop arrays! This guide shows how to build your very own solar charger for small electronics.

This charger will charge most small USB devices such as cell phones, mp3 players, iPods, and iPhones. We have also included a circuit diagram and files for the laser cut enclosure Step 1.

This project was designed for beginner Makers and students. It requires a base knowledge of soldering. While you can charge small gadgets, this project is not appropriate for camping or to be relied on for survival situations. Grab a Kit. This section will be most useful for those sourcing their own parts, if you are building from a kit, feel free to skip ahead. USB charging requires 5V at around mA of power to charge most gadgets.

Nothing comes free though; we trade our increased volts for fewer amps. To avoid this tradeoff, we could use larger solar panels and larger batteries, but this would result in a larger, heavier, and more expensive charger. Most iPhone models, however, require a tweak to USB to work. Unfortunately if it doesn't see anything on the data tabs it will refuse to charge. This is a problem that plagues many generic USB chargers, especially older ones. If you do have an iPhone or iPod you may wish to grab one of these charging circuits , as they're the only ones we have found that seem to work.

We always advise the use of power storage when doing a solar project. Solar is inconsistent due to the inconsistent nature of the sun. Using batteries helps stabilize the flow of power, and also lets us hold onto that energy for later use. In this project we use three rechargeable AA batteries. Rechargeable batteries put out 1.

Four batteries would require a much larger solar cell to charge. Batteries require a minimum voltage in order to charge, but raising the voltage will not cause the batteries to charge faster. The general rule is to provide 1. We want our solar panel to meet the minimum voltage, even on days with a few clouds, so a 6V panel does well. When charging AAs using a wall adaptor, we're able to charge them at high speed due to smart chips that constantly monitor the battery.

This means our 2,mAh batteries should only get mA of current. Our solar cell is rated for only 80mA, so we're completely safe! Different panels and batteries vary, so make sure yours work well together. One good aspect of the trickle charge method is that it will never over-charge the batteries. Once they're full they just stay topped off. Above is a circuit diagram for this project. A diode has been put in place to prevent power from flowing the wrong direction into the solar cell.

This is a very common design for solar chargers. Wood works well because it is non-conductive and easy to paint or decorate. We have included the files here for anyone who has access to a laser cutter. If this isn't an option for you there are more simple ways of making an enclosure.

Inexpensive and easy to find, plastic food containers or bins work well. If possible find one with a rubber o-ring, which helps keep moisture out.

These makeshift enclosures are also are easy to modify with a box cutter or exacto knife, just watch your fingers! It s also possible to find "Project Boxes" at many online stores. These also work quite well for enclosures, but tend to be more expensive. However, we advise against metal enclosures.

Altoids tins and metal project boxes may look nice, but they are difficult to modify and can easily short out projects if left uninsulated. Cut three six inch lengths of wire. If you have our kit, this may already be done. You can also strip the battery pack wires at this time. You should have two wires attached with two loose ends when you are done. If you are using a laser cut case, apply foam tape to the bottom of the solar cell. Leave the protective film on the tape. We won't secure it until the end.

Now thread the wires through the holes in the lid of the case. Optional: It is helpful to use shrink tubing or electrical tape on this setup for protection.

Align all the wires together, then slip the shrink tubing up past the diode. At the end of the project we'll use a heat source to shrink it into place. Solder this to the middle pin on your toggle switch. Take the last 6 inch piece of wire and solder it to either one of the remaining outside pins. It doesn't matter which one. Tip: If you can't thread the wire through the little holes on the Toggle Pins don't worry. Using a Helping Hand you can easily solder to the side of the pins.

Keep in mind that the toggle switch is made of metal and plastic. It is possible to melt it if you hold your soldering iron in place too long. The circuit in our kit has metal tabs coming off of the board which you will solder wires on to. Solder into place.

Wrap the wire coming off the toggle switch around the negative - tab coming off the circuit board. When you finish soldering, clean up by clipping off any bits of wire that stick out. Our USB Circuit has a small three-position switch on the side. Move the switch so that its positioned back towards the soldering tabs. If you have batteries in place the Red LED will be on.

The white LED is not used in this project. You can cut it off, or position it straight up and out of the way. At this point your project should work. Grab a small USB gadget and plug it in. If everything works, use a lighter, hair dryer, or heat gun to close up your shrink tubing over the diode. Are your batteries dead? Try some different AAs, even regular ones, to see if that does the trick.

Is your toggle switch in the right position? Toggle back and forth just to be sure. Is it your gadget? Some large phones and most all tablets won't charge off either circuit. Grab a small mp3 player or different phone to try it out. If none of these fixes work for you, check your wiring to make sure you have good solder connections, and that everything is connected correctly.

The wood enclosure requires a screwdriver to assemble. While the box is strong you should still take care. Over-tightening the screws will break the joints. Make sure you have 16 nuts and screws. It helps to start a nut onto each screw before continuing. Start with the bottom piece and attach the sides to it. The screws will require a small amount of pressure to get into place.

DO NOT screw them in all the way. Tighten them just enough to hold together; we'll tighten them up at the end. Once the bottom and four sides are in place you'll want to attach the electronics.

Screw the toggle switch into place on the side of the enclosure. Put a generous amount of foam tape on the battery pack, and a small piece on the USB Charging Circuit. When putting the battery pack in, pick up the box and apply pressure from both sides. Press firmly until it holds. The USB Circuit may need some extra help to keep from moving around, hot glue works well to keep it stuck down.

Now attach the top, still loosely tightening screws. Remove the foam tape from the solar cell and press it into place, hopefully centered.

What is solar PV system? Solar photovoltaic system or Solar power system is one of renewable energy system which uses PV modules to convert sunlight into electricity. The electricity generated can be either stored or used directly, fed back into grid line or combined with one or more other electricity generators or more renewable energy source. Solar PV system is very reliable and clean source of electricity that can suit a wide range of applications such as residence, industry, agriculture, livestock, etc. Solar PV system includes different components that should be selected according to your system type, site location and applications.

Blue Solaria Co. Even though mini solar panel would possibly prove high-priced to buy, solar power saves money on electricity bills over the longer term because there is no money to pay for the daylight that they use to generate power. Mini Solar Panel 2. Solar Power Manager 5V is a small power and high-efficiency solar power management module designed for 5V solar panel. A wide variety of 5v ma mini solar panel options are available to you, such as mounting type, material, and type. This 2. Mini solar panels, rated from 0.

Each spring I gather solar lights my neighbors tossed in the garbage after the lights have stopped working. The ones that only need minor repairs, I repair, and the ones that need major work I strip for parts and reverse engineer the circuit boards. Most of the circuit designs used in automated decretive garden lights are simple and easy to reverse engineer. Garden lights incorporate three basic circuits, the charging circuit, the dark detecting circuit that turns the LED driver on and off, and the LED driver. Now to get started adding solar power to your small electronics projects and use the sun to power your battery powered night lights, garden lights, and other automated decorations or projects.

Step 1: What You Need

Хейл включил свой компьютер. - Специально для тебя, дорогая. Он стал ждать, когда его компьютер разогреется, и Сьюзан занервничала. Что, если Хейл захочет взглянуть на включенный монитор ТРАНСТЕКСТА. Вообще-то ему это ни к чему, но Сьюзан знала, что его не удовлетворит скороспелая ложь о диагностической программе, над которой машина бьется уже шестнадцать часов.

Simple Solar Circuits

Попытался что-то сказать, но голоса не. Зато был другой голос, тот, что звал. Кто-то рядом с ним попытался его приподнять.

 - Я ничего не сделал. - Ничего не сделал? - вскричала Сьюзан, думая, почему Стратмор так долго не возвращается.  - Вы вместе с Танкадо взяли АНБ в заложники, после чего ты и его обвел вокруг пальца. Скажи, Танкадо действительно умер от сердечного приступа или же его ликвидировал кто-то из ваших людей. - Ты совсем ослепла.

 Или?.  - спросил немец с расширившимися от страха глазами. - Или мы придем к соглашению. - Какому соглашению? - Немец слышал рассказы о коррупции в испанской полиции.

Но он не искал глазами убийцу. Жертва всегда ищет глазами убийцу. Она делает это инстинктивно. Фонтейна эти слова озадачили. - Вы хотите сказать, что Танкадо не искал глазами Халохота.

И увидел, что никто даже не улыбнулся, когда текст был наконец расшифрован. Беккер так и не узнал, какие страшные секреты он помог раскрыть, ни одна вещь не вызывала у него никаких сомнений. АНБ очень серьезно относилось к дешифровке. Полученный чек превышал его месячное университетское жалованье. Когда он шел к выходу по главному коридору, путь ему преградил охранник с телефонной трубкой в руке.

 Клаус Шмидт, - выпалил Беккер имя из старого учебника немецкого. Долгая пауза. - Сэр… я не нахожу Клауса Шмидта в книге заказов, но, быть может, ваш брат хотел сохранить инкогнито, - наверное, дома его ждет жена? - Он непристойно захохотал.

И ради этого стоило убивать. Когда Беккер наконец вышел из Гиральды в Апельсиновый сад, утреннее солнце уже нещадно пекло. Боль в боку немного утихла, да и глаза как будто обрели прежнюю зоркость.
