How is the conversion rate of solar panels calculated?

Introduction How is the conversion rate of a solar panel calculated? The photoelectric conversion efficiency of a solar panel = the maximum output power of the solar panel ÷ the sun shining on the solar panel.

How is the conversion rate of solar panels calculated?

The photoelectric conversion efficiency of the solar panel = the maximum electrical output power of the solar panel ÷ the power of the sun shining on this solar panel.

This measurement is limited to the vertical illumination of the cloudless midday sun at a certain latitude (usually between the equator and the Tropic of the Tropic).

At present, the photoelectric conversion efficiency of most solar panels is around 10%, and very few can reach more than 20%. If it can reach 40-50%, it will be a great achievement and attraction. the attention of the whole world.

Refers to the actual conversion rate after decay. For example, the solar radiation power per square meter is 1000W. The conversion rate of the battery panel is 16%, and the attenuation of the battery panel is 10% (i.e. the maximum conversion rate of the battery panel is 90%) = 1000W*16%*90%=the profinal energy deduction amount.

Application fields of solar panels

< p>1. User solar power supply: (1) Small power supply ranging from 10 to 100 W, used for military and civilian life in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts, etc., such as lighting, televisions. , radio cassette players, etc. ; (2) 3-5KW rooftop grid-connected home power generation system; (3) photovoltaic water pump: solve the problem of watering and irrigating deep water wells in areas without electricity.

2. Transportation field: such as navigation beacon lights, road/railroad signal lights, warning/signal lights, Yuxiang street lights, high altitude obstacle lights, wireless telephone boothswire for highways/railways, unsupervised road changes. food, etc.

3. Communication/communication field: unattended solar microwave relay station, optical cable maintenance station, broadcast/communication/messaging power system; rural operator telephone photovoltaic system, small communication machine, soldier GPS power supply, etc. .

4. Oil, marine and meteorological fields: cathodic protection solar energy systems for oil pipelines and reservoir valves, standby and standby power supplies for oil drilling platforms, ocean sensing equipment, observation equipment meteorological/hydrological, etc. .

5. Lighting power supply: such as garden lights, street lights, portable lights, camping lights, mountaineering lights, fishing lights, lightningblack light ages, rubber tapping lights, energy saving lamps, etc.

6. Photovoltaic power plants: independent photovoltaic power plants from 10KW to 50MW, wind and solar (diesel) complementary power plants, various charging stations for large parking power plants, etc.

7. Solar buildings: The combination of solar power generation and building materials will make future large-scale buildings electricity self-sufficient, which is a major development direction for the future.
