How To Do It Yourself Solar Power
 The world is facing energy crisis. In such times it has become necessary that we all start looking for alternatives at individual levels. One such initiative is to trap the sun’s heat to produce energy. Simple devices like solar cooker and water heater can help you achieve your electricity saving target. These devices can also be built at home thus saving you the expense of buying them. More..

Advantages of Solar Energy
- Energy from the sun is absolutely free. The only initial expense required is to install solar devices. But the cost of these is recovered soon.
- Government gives incentives for using solar energy at homes and in industries. Applying for these incentives reduces the cost of solar devices.
- If your need for energy is less than what is produced, you can sell it to a willing customer.
- Your savings increase since you aren’t consuming electricity, which is costly and leaves you with a bill end of every month.
- You need not depend on the electricity to run your house. Even power cut will not affect the solar energy supply.
- Sunlight is available in plenty and this energy does not depend on the supply vs demand model.
- No other fuel is required to convert sun’s rays into energy.
- Dependence on natural fossil fuels is reduced. This can help stabilize the price of crude oil.
- Very low maintenance cost. Solar devices operate smoothly and quietly.
- Everything is natural. This is great news especially for the health conscious.
Disadvantages of Solar Energy
- Initial cost of installation can be a little high. This is because the semi-conductor used in solar devices is a little expensive.
- Good amount of sun’s rays are needed for the solar device to work efficiently.
- Large area is required to position the device. The reason is that the solar panels are build big in size to trap maximum heat.
- There is no solar energy available at night time.
- Heating with solar energy does take time and requires patience on the consumer’s part. The question is how many of us have that kind of time today.
