Passive Solar Heating imagine what you can do for your house or maybe use this model to help heat your RV!
Passive solar heating is by far the best way to use your resources without breaking the bank. The reason it is called passive is that there is no conduction of electricity involved to transfer this heat energy. There are many versions of this type of solar heater made by people, with video on the internet. Some use soda cans or other favorite beverage cans to trap heat and transfer it into there home, cabin, single wide or tent. It is a more advanced version of a trombe wall. This type of wall will absorb solar heat and transfer it to the air.
Although a Trombe wall or 'soda can heater' is a popular use of passive solar heating there are other instances. You can see it in solar water heaters, solar pool heaters and many pool covers take advantage of this by being transparent or clear in color. With that in mind you should think about these concepts when considering passive solar heating: heat rises, cold sinks, hot water is less dense than cold water, flat black absorbs heat, black gloss will reflect light (and heat), light colors reflect heat and glass will trap heat.
The inclusion of passive solar energy for heating doesn't mean that during hot days you have to spend a fortune on utility bills. Include sky lights or "solar tubes" for lighting your home when the sun is away from the southern facing windows. This has an added benefit of reducing the amount of passive heat entering your house during the Summer when the sun is at a higher elevation. The "solar tubes" still allow for light to enter without the extra heat.
Passive solar heat is also the main concept behind ZED or zero energy design. This design technique maximizes the use of glass in home building, optimizes space used for living conditions and use of materials that absorb heat. Passive solar heating, when used properly can reduce the energy cost of Solar Powered Homes.
Solar Power Information
Solar Panel Systems How Do I Estimate My Solar Power System Needs and Size?
The first step in determining your solar power needs is, knowing what your typical average energy usage is. If your total energy usage is, on average, around 6000 kilowatts per year, you will have to determine how much of that will be generated by your solar panel array.
An alternative is to compromise: modify your lifestyle and energy consumption while allowing the solar panel to generate the majority of your reduced energy needs.
The cost per kilowatt for a professionally installed panel will be slightly higher. The total cost of your system would be $30,000, or $42,000 installed. A slightly smaller system can generate a portion of your energy usage, however, you will still be paying an energy bill in this case.
