Solar Cooking Is Easy and Cheap Too
Did you know you can cook entire meals without any electricity or gas? It’s true. If you have access to the sun then you can cook with it.
Cooking with the power of the sun is commonly referred to as solar cooking, and you don’t need expensive gadgets or equipment to do this successfully either. Solar cooking requires sunlight of course, a bit of time, a few everyday items, and a willingness to experiment.
In the most basic form, solar cooking can be done easily as long as you have decently strong sunlight for a few hours. The stronger your sunlight is of course, the easier your solar cooking will be. In the desert southwestern areas of the United States for example, you can literally just lay food out in direct sunlight in the summer and it will cook quickly for you. We’re going to look at a little more than the basics here though.
There are two primary ways to cook food with solar power. One is to use what’s known as a parabolic cooker, and the other is to simply use reflecters.
A parabolic cooker is actually just anything you have on hand which has a slighly bowled, or parabolic shape to it. Round satellite dishes are excellent examples of this type of inward curved surface. The slight curve of a surface like this will allow you to concentrate the natural heat of the sun onto the food you’re cooking.
Parabolic cookers can be made with simple cardboard, or any slightly concaved material such as an old (small) sattelite dish, a small wok, or even a bent and curved trash can or barbecue lid. Using old materials for this is great because it allows you to recycle and it doesn’t usually cost a thing.
Most people choose to make their first solar oven with cardboard because it’s readily available, easy to work with, and free.
The best parabolic solar cooker will have slanted sides though, not upright ones. A slant of about 60 degrees outwards is ideal. Once you find the object you plan to use for your solar cooking, then you simply cover it with tin foil, mylar, or mirrors. Mirrors can actually be dangerous because too much heat is generated, so it’s best to start with aluminum foil. Cover your concaved object with the foil so that the shiny side is facing out. This will capture more of the sunlight shining down on your solar cooking, and help focus it onto your food.
Simple reflector style solar cookers are another popular option, and in many cases you don’t even have to put things together to make this work. With this style of solar cooking, you simply put a pot or pan out into direct sunlight and surround it on three sides with reflective material to help direct the solar heat to your food.
With either solar cooking design though, you’ll want to use either glass or dark metal cooking pots and pans. Dark metal helps attract and absorb the natural solar heat from the sun, and glass allow that solar heat to pass through easily yet stay trapped inside for cooking.
Depending upon the strength of the sunlight you have available and the solar cooker design you’re using, it can take anywhere from one to three hours to fully cook common meals for three to five people.
Of course you can also use regular solar panels or a solar power generator kit to power a more conventional energy efficient stove or oven when the sun isn’t strong enough to use your solar cooker, or if you prefer to cook foods in a more traditional manner.

Solar Collector The Heart Of A Solar Heating System
Executive Summary about Solar Collector by Armand Hadife
Solar energy is accessible in plentiful places around the world. This high temperature produced can be exploited for heating air or water in houses and buildings
Using solar energy is a natural and affordable approach for spaces or water heating. When using solar power for heating purposes you employ a device that will allow capturing the heat of the sun. This device is called a solar collector. A basic solar collector can be made with no difficulties.
The next step is to find a system to help circulate water or air inside the solar collector. In general, devices like fans and pumps are used to push air or water thru the solar collector and from the storage tank to the house.
For the novice, making a solar collector can be a difficult and demanding project. This is why solar collectors are broadly offered online and in solar products shops.
How to Build a Solar Collector
Executive Summary about Solar Collector by Mick Jeys
Building a solar collector is the best way to save money on electricity bills, and can be used to generate electricity or to heat water. The two most popular uses for solar collectors are to heat water and generate electricity.
Solar Collector To Generate Electricity
Typically known as a solar cell or panel, they are typically made from titanium dioxide, and create electricity through the photovoltaic effect. It is now very simple to build your own generator at home quite cheaply by substituting titanium dioxide with cuprous oxide.
Solar Collector To Heat Water
The most common example of this type can be seen in common solar hot water systems, where the hot water tank is actually up on the roof with the solar collector. Trials are being held in Germany to use solar heated water from the summertime to heat homes in the winter.

Residential Solar Energy – Solve the Solar Energy Mystery
Executive Summary about Residential Solar by L J Sutherland
Residential solar energy can be incorporated into your home in many ways. The most commonly used system in homes today is the solar powered water heater. This system requires the installation of a solar panel on your roof or garden. The other system that you can use in your home is the use of photovoltaic solar panels. These panels convert sunlight into electricity. Residential Solar Energy Points to Remember:
- The most commonly used system in homes today is the solar powered water heater.
- The other system that you can use in your home is the use of photovoltaic solar panels.
- Many countries all over the world are providing tax rebates, tax credits and sometimes even subsidies for the installation such residential solar energy systems.
- If purchasing a ready made solar energy system proves to be out of your budget, you can consider building your very own unit at home. There are various DIY residential solar energy system plans available on the Internet.
Residential Solar Power – Solar Power For Homes
Executive Summary about Residential Solar by Jon Elsdon
Residential solar power for homes has become a must if we are to free ourselves of the rising cost of traditional power resources such as fossil fuels. Residential solar power for homes is the simplest alternative energy installation we can preform on our homes. Easy to install and maintain (solar panels have a life span of around 30years) a residential solar power system will have you saving money for years to come.
Regardless of whether you are looking to totally power your home with solar or are looking to supplement traditional power sources to give you a cheaper, more reliable (no more power outages), unrestricted power resource, solar power is the way to go.
Many households are turning to DIY (Do It Yourself) solar power projects.

Solar Hot Water
Executive Summary about Solar Hot Water by Anna Williams
Solar hot water heating systems are a great way to effectively conserve energy and reduce your energy bill.
Important Facts about Solar Hot Water Systems
- Solar water heaters can be used in any climate.
- The fuel used to run a solar heater is sunshine.
- A solar water heater can reduce your water heating bill by fifty to eighty percent.
- Aside from reducing your energy bill right now, a solar heating system will protect you from future energy price increases.
- When building a new home, or when refinancing, the economic aspect of this becomes even more interesting.
- Using solar power to heat your water will significantly reduce your carbon footprint.
- Solar heaters can be installed in combination with backup systems.
Types of Solar Hot Water Systems
There are two types of systems, “active solar water heating systems” and “passive solar water heating systems.” With a passive system, the water storage tank must therefore always be positioned above the solar water heater collector.
Active Solar Hot Water Systems
There is also the direct circulation system, where water is simply passed through solar heat collector and then routed to the water storage tank for use.
Passive Solar Hot Water Systems
Passive solar water heating systems are usually cheaper than “active solar water heating systems,” as they do not need controls or pumps to circulate the water.
If you live in a warm climate, a passive water heating system might be all you need. Essentially, solar water heating systems consist of a water storage tank and its solar collectors. The solar collectors are used to collect solar energy (which heats water), and the tanks store the heated water. 75% of the energy consumption of the average home is for hot water and heating. The most economical and effective way of using solar power is through the use of solar heating, and solar hot water heaters.
Homemade Solar Hot Water Heater – One of the Easiest Home Renewable Energy Systems You Could Make?
Executive Summary about Solar Hot Water by Denzil De Vries
Installing a solar hot water system is one of the easier projects to undertake if you are keen to create your own home made renewable energy systems.
The key to the solar hot water system is the solar collector. It is just a tank that has been modified to absorb thermal energy from the Sun. So it may be painted black on the external surfaces and have insulation on the internal surfaces to prevent heat loss.
The flat plate solar collector design uses the same principles but is designed to squeeze even more juice out of the Sun. The plate is painted black to again absorb solar radiation and heat. Along the plate is tubing that will hold water. The tubing exposes far more water to the heat than the ordinary old solar collector. This means more water is heated or made hotter.
Where you place your collector is vitally important but is dictated by two factors. It needs to get as much Sun as it can, so a south facing location in the home is best. But it also needs to move water to the boiler system in the home. So the nearer it is to the boiler the better. If the boiler is well located you could position the solar water collector above the boiler and let gravity move the water from boiler and back to collector based on the heat of the water.
A solar hot water system can be a simple as a solar water collector that has no moving parts or electricity to worry about and a connection to your boiler system.
Most people look into a solar hot water heater because they want to save money on their heating bills. With this in mind a solar hot water heater will help to reduce your bills by pre-heating water that goes into your traditional boiler.
