Why Solar Energy Is Clean Energy?

Solar energy, in general, refers to the radiant energy of sunlight, and solar power is the direct conversion of solar radiant energy to photothermal, photovoltaic and photochemical. Solar energy as a clean energy source has the following advantages.
(1) Universal: the sun's rays shine on the earth, there is no geographical limitation whether on land or sea, whether mountains or islands, are everywhere, can be directly developed and used, and no mining and transportation.
(2) Harmless: the development and use of solar energy does not pollute the environment, it is one of the cleanest energy sources, which is extremely valuable in today's increasingly serious environmental pollution.
(3) Huge: The annual solar radiation energy reaching the earth's surface is equivalent to about 130 trillion tons of coal, the total amount of which is the largest energy source that can be developed in the world today.
(4) Long-lasting: According to the current rate of nuclear energy generated by the sun, it is estimated that the storage of hydrogen is enough to maintain tens of billions of years, and the life span of the earth is also about billions of years, in this sense, it can be said that the energy of the sun is inexhaustible.

What's Conditions For Solar Power Farm And How We Recover It?

Conditions for building solar power stations.
1.Light and heat conditions, long daytime, sufficient amount of sunshine, no long-term cloudy days, rain and snow, the sun should be hot and strong
2.Complete supporting facilities, convenient transportation, close to substations, reduce transmission costs, in order to achieve grid-connected power generation, easy to install and maintain
3.Flat and open terrain, large plain area, such as sandy land, desert, grassland, etc.
4.Sufficient land and low land rent
5.Policy support


How To Get Solar Data And Data Analysis?

1.Solar photovoltaic power resource data, solar radiation data can be obtained from county-level weather stations or from the National Weather Bureau. The data obtained from the meteorological bureau is horizontal radiation data, including: horizontal total radiation, horizontal direct radiation and horizontal scattered radiation. The solar energy resource data include mainly: total solar radiation (irradiance) by month or monthly daily average of total solar radiation and radiation intensity.

The data of climate conditions related to it mainly include: annual average temperature, annual average maximum temperature, annual average minimum temperature, the longest consecutive cloudy days in a year (including precipitation or snow days), annual average wind speed, annual maximum wind speed, annual number of hailstorms, and annual number of sandstorm days. Among them, the monthly values of total solar radiation are essential. In addition, the cumulative data for the last 5-10 years for each of the above data should be provided to assess the validity of the solar energy resource count and climate condition data.

2.Assessment of the validity of solar resource data. Solar energy resource data provided by meteorological stations or related departments are used for solar PV system design, and their validity still needs to be evaluated in some cases. First, when the solar power resource data for a specific site is not complete enough or lacks cumulative data for many years, the validity and quantity of solar radiation must be evaluated.

3.Although the local solar energy data are relatively complete and the solar radiation situation is good, there are topographic features near the candidate site that significantly affect solar radiation because the candidate site is in a hilly area cargo. In this case, the validity of the local solar power resource data should be evaluated by studying the average data variation in the neighboring areas around the candidate site.

 4.The data obtained from the meteorological department are horizontal plane data, including horizontal plane direct radiation and horizontal plane scattered radiation, so as to obtain the total radiation data on the horizontal plane. However, in the practical application of solar photovoltaic power generation, in order to get more power generation and the need for self-cleaning of the cell modules, the fixed installation square array is usually tilted, which requires the calculation of solar radiation on the tilted surface (usually greater than the radiation on the horizontal surface) in order to calculate the data of the whole power station.

About Boland PV Panel

1) Double-sided double-glass module advantages
Weathering performance: PERC double-glass double-sided modules, backplane organic material replaced by inorganic material glass, impervious to water, long-term outdoor degradation-free, integrated double-glass components anti-PID characteristics, to prevent the cell black line, strong resistance to hot spot; also has resistance to salt fog, acid and alkali, sand and dust, to meet the high temperature, high and low acid and alkali salt fog and other harsh environmental use and 1500V high efficiency, low-cost system and other advantages, the average attenuation The average attenuation is lower than ordinary modules, and the module power warranty is extended from 25 years to 30 years, so the service life is longer.
30 years power warranty: 25 years power warranty for back panel modules, 0.55% attenuation per year; 30 years power warranty for double-glass modules, 0.45% attenuation per year.
Weak light property: Excellent low irradiation performance enables the PV plant to work earlier and stop working later, which in turn increases the power generation gain.
Temperature characteristics: The glass structure of double-glass double-sided modules is more resistant to abrasion and corrosion, and the water permeability is almost zero. The fire rating is also upgraded from C grade to A grade for ordinary crystalline silicon modules, which is widely applicable to various application environments such as high temperature, high humidity, desert and seaside. The double-glass structure has no backsheet and no combustible material, thus it has excellent fireproof performance.
Technology compatibility: Double-glass modules can perfectly match with current industry bifacial cell technology (P-type PERC, N-type Topcon, HJT and other cell technologies), half-sheet technology, multi-main grid technology, 210 large-size wafer technology, etc., which greatly improves the cost performance of PV panel modules.
