Solar cooking is the simplest, safest, most convenient way to cook food without consuming fuels or heating up the kitchen. Many people choose to solar cook for these reasons. But for hundreds of millions of people around the world who cook over fires fueled by wood or dung, and who walk for miles to collect wood or spend much of their meager incomes on fuel, solar cooking is more than a choice it is a blessing. For millions of people who lack Read the rest of this entry »

Evaluation of solar water heater system design, the evaluation should focus on the following five points, you can basically reflect the merits of the design: 1, the adequacy of the design heating water? Collector area, water tank capacity is big enough? 2, auxiliary heater power is big enough? In principle, the rainy-day start electric auxiliary heat should be 3-5 hours in the water to fully meet the requirements to start the heat pump and heating should be complete within 8-16 hours to meet the water requirements; 3, if the user’s water consumption, water use changes over time, the system can meet user requirements? (Because in actual use, the user’s water consumption, water is often the time change); 4, in all weather conditions, in a variety of water Shi Jian, changes in the Qing Kuang under water, the system whether the maximum use of solar energy Liao, Xiao Hao Zuishao to conventional energy sources, Ji is Zuitaichengduo to Jieneng? 5, cost is the highest? 2, auxiliary heater power is big enough? In principle, the rainy-day start electric auxiliary heat should be 3-5 hours in the water to fully meet the requirements to start the heat pump and heating should be complete within 8-16 hours to meet the water requirements; If you compare a variety of programs and found the answer to these questions is yes, then the design is very good, otherwise there is a problem as long as the answer is no, then the design is not perfect, or even no pass, the purchaser as long as their intelligence, knowledge, control over evaluation of five aspects, we can make a decision of their own.

With electric water heaters and gas water heater, solar water heaters have many advantages:

1, solar energy inexhaustible. As long as the sun, solar water heater can be converted to light and heat, can be run throughout the year
2, green. Solar energy as a clean, renewable energy, no pollution, no security risk; Read the rest of this entry »

Advantages of solar energy

Solar’s biggest advantage is that there’s so much of it. The total solar energy available to the earth is approximately 3850 zettajoules (ZJ) per year, while worldwide energy consumption was 0.471 ZJ in 2004, according to the US Department of Energy. Even if you aren’t a solar panel installer, you can tell that there’s way more solar energy Read the rest of this entry »

Disadvantages of solar energy

Solar energy’s disadvantages can be pretty well boiled down to one thing: cost, at least for using it as electricity. It takes a lot of land and costs a lot of cash to be worthwhile, as most types of solar cells require large surface areas to achieve average efficiency, and the silicon used in many of today’s cells is also very expensive. Pollution and weather can further cut back their efficiency, which, of course, increases the cost over time. Read the rest of this entry »
