The maximum power generation voltage of the calibrated solar panel is six volts, and the battery capacity is 8,800 mAh (6*8,800 = 52,800/1,000 = 52.8). The calculation shows that the stored power of the battery is 52.8 watts/hour. . This amount of electricity (52.8/6=8.8) allows this six-watt bulb to stay lit for approximately 8.8 hours on a full charge.
To give you some data, a complete system (including solar panels, inverters, batteries and charging devices) costs around 18 yuan/watt. Therefore, if you need to install 3000 kilowatt solar power generation. system, it will cost around 50,000 to 60,000. Solar power generation systems with too low power are generally not suitable. Usually a family has a refrigerator, a TV, a 1.5 HP air conditioner, 2-3 lamps, etc., which require around 2000 watts. GeneraGenerally, a home solar power system should be around 3 kW. Just calculate it in watts.
Compared with commonly used thermal power generation systems, the advantages of solar photovoltaic power generation are mainly reflected in:
① No risk of depletion ② Safe and reliable, no noise, no noise; pollution emissions, absolutely clean (no pollution); ③ not limited by the resource distribution area, can take advantage of the roof of the building; ④ can generate electricity on site without consuming fuel or erecting transmission lines ⑤ high power quality; accept emotionally;⑦ The construction period is short and the time spent on obtaining energy is short.
Disadvantages:
① The energy distribution density of irradiation is low, that is, it occupies a huge area ② The energy obtained is linked tofour seasons, day and night, cloudy and sunny and other weather conditions. The origin and development of photovoltaic solar energy production.
