There are several types of solar energy production. One is crystalline silicon, including monocrystalline silicon and polycrystalline silicon, the other is amorphous silicon power generation, which is not crystalline silicon. There is thin film solar and flexible solar. Due to the low conversion rate of amorphous solar cells, crystalline silicon solar power generation is now more widely used.
Regarding your approximate power output per square meter per day, generally speaking, 1 square meter of crystalline silicon solar panels is equivalent to about 120-140 W. If calculated as 120 W, the power of the sun at 6 a.m. day, i.e. 120*6=720WH. A 10W lamp depends on how many hours you use it per day and how many consecutive rainy days you use it. If you use it 9 hours a day and 3 daysbear rain, then the battery panel is 30-50W.
Our company is a manufacturer specializing in the production of solar components and power generation systems.
> Taking a one square meter crystalline silicon solar panel with relatively high efficiency as an example, it can generate 180W of electricity per hour. The duration of sunshine varies from place to place. Generally, the effective solar power generation time in most areas of China is 3 hours. In other words, one square meter of solar panels generates 0.54 kW per day. The average household must take into account the total amount of electricity used by various lighting fixtures and appliances. Taking into account the power demand at night or during periods of non-efficient power generation, the battery capacity shall be confirmed to be 5 kW. Generally, a battery panel of 30 square meters morea 5,000 W system. The total price is around 50,000 yuan. /p>
