When you want to build your own small solar power station, the first thing you need to consider is how high-power solar power generation system you can use. Now we will calculate for you, hoping to bring you help.
When you want to install a solar panel power generation system, as long as you install the board, you can use as many kwh as you want. As for the choice, you need to calculate the total wattage of all electrical appliances in your home, and drive all electrical appliances.
For a family, the basic electrical appliances include: color TV 65W satellite receiver 25W LCD computer 100W fluorescent lamp 28w energy-saving lamp 11wdvd10w combination sound 100W hair dryer 450W vacuum cleaner 800W electric iron 500W electric water heater 1000W mobile phone charger 2W electric heater 1200W electric rice cooker 500W.
Through the above average power calculation of electrical appliances, you can calculate your total power. At the same time, it should be noted that not all electrical appliances work 24 hours, and some electrical appliances work only a small part of the time.
In addition, solar cells are not directly powered, but battery powered. Therefore, when the appliance is not on, solar panel power generation is constantly storing power for the battery, which has been provided for standby.
7 steps for grid connection of household solar power station:
1. Apply to the business hall of the power bureau and fill in the grid connection application form（ Families need to bring the ID card of the head of household and its copy, household register, house property certificate and other relevant certificates when applying.)
2. The power supply department shall conduct on-site investigation and issue a personalized grid connection scheme within 10 working days.
3. Confirm the grid connection scheme.
4. The family shall carry out the detailed design of photovoltaic power station according to the grid connection scheme.
5. According to the relevant technical requirements, the capacity of 5 kW to 6 kW is enough for ordinary families. Contact professionals for door-to-door installation.
6. Families apply for grid connection commissioning, power supply enterprises install meters, organize acceptance, and sign relevant agreements.
7. After testing, the grid connection is officially completed.
