Solar Energy and Systems

Many of us know that solar energy is a good thing, but few really understand why. Therefore, I compiled a comprehensive list of solar energy advantages and disadvantages that will enable you to make an educated decision whether on not Solar Power is right for YOU.

Solar Energy Advantages

1. Saves you money

• After the initial investment has been recovered, the energy from the sun is practically FREE.
• The recovery/ payback period for this investment can be very short depending on how much electricity your household uses.
• Financial incentives are available form the government that will reduce your cost.
• If your system produce more energy than you use, your utility company can buy it from you, building up a credit on your account! This is called net metering.
• It will save you money on your electricity bill if you have one at all.
• Solar energy does not require any fuel.
• It’s not affected by the supply and demand of fuel and is therefore not subjected to the ever-increasing price of gasoline.
• The savings are immediate and for many years to come.
• The use of solar energy indirectly reduces health costs.

2. Environmentally friendly

• Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment.
• It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury into the atmosphere like many traditional forms of electrical generations does.
• Therefore Solar Energy does not contribute to global warming, acid rain or smog.
• It actively contributes to the decrease of harmful green house gas emissions.
• It’s generated where it is needed.
• By not using any fuel, Solar Energy does not contribute to the cost and problems of the recovery and transportation of fuel or the storage of radioactive waste.

3. Independent/ semi-independent

• Solar Energy can be utilized to offset utility-supplied energy consumption. It does not only reduce your electricity bill, but will also continue to supply your home/ business with electricity in the event of a power outage.
• A Solar Energy system can operate entirely independent, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations (like holiday log cabins), making it more practical and cost-effective than the supply of utility electricity to a new site.
• The use of Solar Energy reduces our dependence on foreign and/or centralized sources of energy, influenced by natural disasters or international events and so contributes to a sustainable future.
• Solar Energy supports local job and wealth creation, fuelling local economies.

4. Low/ no maintenance

• Solar Energy systems are virtually maintenance free and will last for decades.
• Once installed, there are no recurring costs.
• They operate silently, have no moving parts, do not release offensive smells and do not require you to add any fuel.
• More solar panels can easily be added in the future when your family’s needs grow.

Solar Energy Disadvantages

• The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of the semi-conducting materials used in building one.
• The cost of solar energy is also high compared to non-renewable utility-supplied electricity. As energy shortages are becoming more common, solar energy is becoming more price-competitive.
• Solar panels require quite a large area for installation to achieve a good level of efficiency.
• The efficiency of the system also relies on the location of the sun, although this problem can be overcome with the installation of certain components.
• The production of solar energy is influenced by the presence of clouds or pollution in the air.
• Similarly, no solar energy will be produced during nighttime although a battery backup system and/or net metering will solve this problem. See http://www.dsireusa.org for details on how net metering allows you to save electricity and money.
• As far as solar powered cars go – their slower speed might not appeal to everyone caught up in today’s rat race.

Solar Energy Information

Passive solar heating and passive cooling—approaches known as natural conditioning—provide comfort throughout the year by reducing, or eliminating, the need for fossil fuel. Yet while heat from sunlight and ventilation from breezes is free for the taking, few modern architects or builders really understand the principles involved. Now Dan Chiras, author of the popular book “The Natural House,” brings those principles up to date for a new generation of solar enthusiasts. The techniques required to heat and cool a building passively have been used for thousands of years. Early societies such as the Native American Anasazis and the ancient Greeks perfected designs that effectively exploited these natural processes. The Greeks considered anyone who didn’t use passive solar to heat a home to be a barbarian! In the United States, passive solar architecture experienced a major resurgence of interest in the 1970s in response to crippling oil embargoes. With grand enthusiasm but with scant knowledge (and sometimes little common sense), architects and builders created a wide variety of solar homes. Some worked pretty well, but looked more like laboratories than houses. Others performed poorly, overheating in the summer because of excessive or misplaced windows and skylights, and growing chilly in the colder months because of insufficient thermal mass and insulation and poor siting. In “The Solar House,” Dan Chiras sets the record straight on the vast potential for passive heating and cooling. Acknowledging the good intentions of misguided solar designers in the past, he highlights certain egregious—and entirely avoidable—errors. More importantly, Chiras explains in methodical detail how today’s home builders can succeed with solar designs. Now that energy efficiency measures including higher levels of insulation and multi-layered glazing have become standard, it is easier than ever before to create a comfortable and affordable passive solar house that will provide year-round comfort in any climate. Moreover, since modern building materials and airtight construction methods sometimes result in air-quality and even toxicity problems, Chiras explains state-of-the-art ventilation and filtering techniques that complement the ancient solar strategies of thermal mass and daylighting. Chiras also explains the new diagnostic aids available in printed worksheet or software formats, allowing readers to generate their own design schemes.

Thorough, concise, and up-to-date info for solar designs
By A
I have spent a lot of time researching passive solar designs using books from the library & information on the internet. A lot of books on solar designs are from the 70′s & 80′s and the designs lead to overheating of homes by overglazing (too many windows). Some of the more current books on solar design gave more vague information, and didn’t thoroughly describe concepts and materials.

This book has it all! Very good information on all the design elements, such as direction of home, foundation designs, window ratios, as well as recommendations for particular products. The book had in-depth information on all the available heating systems including solar heating, heat pumps, & radiant floor heating. At the end of the description for each heating system, there was a pro/con list that talked about the energy effiency, cost, & performance of each heating system over others . There was a helpful chart on hot water heaters with payback periods for different fuels (solar, electric, gas, propane) so you could compare the costs associated with the fuel. In all of my research, this was the first such chart that really spelled out the benefits of certain fuels over others. The book was written in 2002, so it is very up-to-date with the most current products & concepts.

An excellent guide for embracing ecology-friendly living
By Midwest Book Review
The Solar House: Passive Heating And Cooling by global environmental issues expert Daniel D. Chiras is an “user friendly” architectural guide to choosing and implementing an energy-efficient and environmentally friendly backup heating system, and thereby making any dwelling both cost-effective and naturally heated and/or air conditioned. Black-and-white sketches clearly illustrate the detailed walk-throughs about the basics of passive solar heating, passive cooling, assessing the performance of one’s energy system and much more. An excellent guide for embracing ecology-friendly living, The Solar House is especially recommended as a do-it-yourself home reference for the non-specialist general reader with an interest in making their personal home as comfortable and environmentally friendly as possible.

A Brilliantly Simple Solar Design Book
By David L. Wann
At last — a comprehensive, easy-to-read, well-illustrated solar house book, perfect for architectural students, build-it-yourselfers and masters of solar technology as well — who will benefit from the many important lessons learned.

My delight with the book began when I first saw its elegant cover. The more I read, the more I realized what a treasure it is. I was especially interested in the latest information on radiant floor heating, ground source heat pumps, and passive cooling. It makes me feel good to know that a book this full of information, yet so accessible, may result in significant reductions in the 44% of total household energy used for heating and cooling.

Chiras combines several decades of personal experience with information from some of the best minds in the field. His stated goal of producing a comprehensive and accurate book is well met. Nice job — get a copy!
