The router is not very powerful. You said it uses a lot of energy. Why does it use so much energy? Routers are usually powered by 12V. They can also be powered by solar cells, but the cost is not low. First of all, the price of solar panels is too high and you also need to buy rectifiers, batteries and some wires. The solar cell provides energy to charge the battery during the day and then powers the router. The battery should be at least 12V 7A. This approach is not recommended as the investment cost is high.
The specifications for distributed (domestic) photovoltaic power generation are approximately five kilowatts of photovoltaics. When the lighting is normal, the daily power output seems to be around twenty watts (I can't remember clearly, maybe ten). kilowatts of photovoltaics,). At first glance, the capacityity of electricity production seems correct, but the voltage generated by the production of photovoltaic energy is not 220 volts. You must first install a transformer (it must be approved by the local power supply department, the price is unknown.) and. then prepare an inverter (can 24 If you work continuously for an hour, it costs about a few thousand yuan). If the photovoltaic does not produce electricity at night, a set of batteries must be installed to store the electricity produced during the day for use at night (a maintenance-free battery can power a 12 watt light bulb for 24 hours costs around 200 to 200 euros). 500 yuan. The price to power a refrigerator, television and air conditioner is approximately...
