Millions of poor homes in Philippines – and a lot more around the world – in the dark because the metal roof block all light and no connection to electricity in informal settlements.
A student of MIT found that one-liter plastic bottle filled with water and bleach and then mounted on a metal roof is a simple way to light homes that have no electrical connectivity or natural lighting. It was called Solar Bottle Bulb.
Executive Summary about Sun Power by Richard Chapo
Generating electricity from the sun is all about converting sunlight into power. The technology behind solar systems is known as photovoltaic technology. Essentially, this technology involves using sunlight to create a chemical reaction. This process creates a direct current of electricity. The electricity is then converted to usable alternating current electricity and stored in a battery or fed into a utility grid system.
A fantastic way of generating electricity today is by way of wind power. There is a great deal of interest in home made energy all over the world today due to the costs of installation being so low and how effective home made energy is.

Grid-connected system was applied to many urban areas housing, existing electricity network. The purpose of using solar panels, to save the cost of excessive electricity consumption and help reduce the greenhouse effect caused by the use of fossil fuels which cause excessive air pollution. Electrical energy which is in turn, channeled into the electricity networks that already exist and can be stored in the electricity network. This term is called the Hybrid System, which combine solar power plants with electricity network. Solar systems can also be combined with other power plants such as PV-Generator Hybrid, Hybrid PV-Microhydro, Hybrid PV-Wind and can even be combined into 3 systems of different power to Hybrid PV-Wind-Generator.

Many people, especially those who are beginners in solar technology may wonder how solar panels work. But first, what is the home solar panels? This is a solar-powered gadget that collect and use the energy from the sun through its rays and convert it into power.
Some people use solar panels home gadgets to act as an alternative source of energy for their small household, effectively complements the consumption of electricity from local utilities.
There are still homeowners who invest in residential solar panels are fully able to provide power to the house, run all appliances, water heaters and swimming pool. However, the cost is very expensive if you intend to own and install your own home solar panels that will work as the only source of daily strength. A solar panel unit actually has a very high price from a few thousand dollars.
How solar panels work can be answered simply. He has a photovoltaic cell in a panel that primarily works by collecting energy from sunlight that falls on them, then solar energy is converted into electrical energy for use at home.
You may very well consider this gadget as an investment, because you need to shell out large enough amount of money to buy and install them as your resource. It is a serious investment even if you only need to spend the money early, the amount needed is really great. After purchase you do not have to worry about this as the sun runs his own gadgets, making endless supply of electricity to your residence with the help, of course, the sun.
Many supporters of a clean environment and recommended the use of green house solar panels, if only because the energy that collects and converts power from the sun. Therefore, the power generated is clean and not harmful to the environment of the world. Likewise, you do not have to worry about running out of the sun’s energy for endless supply. Solar energy is a clean renewable energy, and is considered the best alternative energy is there.
Executive Summary about Solar Battery Charger by Anna Stone
Solar Battery Chargers are used to charge your batteries when you are not connected to the power grids and do not have access to another form of electricity. The way a Solar Charger works is simple. The solar panel of the battery charger collects energy from the sun and converts this into electricity. Now, there are many different types of solar battery chargers, as well as different types of batteries you might want to charge. Some solar chargers are more powerful than others. As all solar battery chargers use some type of solar panel, the amount of power they generate generally depends on the size of the panels. Solar panels are made up of individual solar cells. Solar cells are the units which create electricity out of sunlight. The more solar cells there are on a solar panel, the more electricity they create. So you will generally find that bigger solar panels produced more energy, and smaller solar panels produce less.
Some solar battery chargers work with simple AA batteries, like those that you would use to run a flashlight. Some charge the batteries of your equipment, such as the battery in your laptop computer.
You might ask why one uses a solar charger to charge a battery, instead of just directly running one’s equipment from a solar panel.
The sun’s heat might damage your cell phone. There are a variety of solar battery chargers and other portable solar power devices available on the market today. Further information and answers to common questions can be found at Solar Chargers and Portable Solar Power Devices.

Pool Solar Heaters – How to Build Your Own Pool Solar Heater
Executive Summary about Solar Heaters by Benjamin Robert Ehinger
Here is a plan to put together your solar heater.
First, you are going to need about 150 feet of long black tubing that is about a half inch around to three fourths of an inch around. You will also need about 10 feet of PVC pipe that will fit snugly into the ends of the black tubing. you will need a shut off valve that will be attached to one end of the PVC piping. You will also need a pump that will be strong enough to move water through the tubing at a slow speed.
Second, you are going to need some 2 by 4 pieces of lumber and some metal brackets. You will want to mount this part of your heater on a rooftop that is in direct sunlight, a shed, a barn, a garage, or anywhere else that is in direct sunlight.
Last, you will run the PVC piping from each end of the black tubing into the pool. When you turn the pump on it will suck water out of your pool at a slow speed and pump it up and through your black tubing, very slowly. You want this water to be sitting in the black tubing and getting hot. Then, when it comes back into the pool it will start to raise the temperature of your pool. This is now your solar pool heater.
