Hybrid wind and PV system to power Mobile Base Station
When planning remote cell sites the service provider has a number of possible power solutions options.
Diesel generators are one of the most popular selections when a main grid connection is not available or it will take months or years to connect. Diesel generators remain cheaper to install but this is offset by higher operating expense, especially in cases where it needs to be delivered to cell sites without road access, and often gets siphoned off. Moreover, diesel fule supplies are heavily prone to theft.
The diesel-free power system has been positioned as a green alternative to using fuel generators but this still leaves the problem of refueling that wind and solar-power generation eliminates.
Hybrid wind and solar powered stations require less maintenance than a fuel driven generator which generally requires, at a minimum, a monthly visit for refueling. We have gone for a hybrid wind and solar powered system (rather than selecting one or the other) because it can supply much stable power output due to good complement of wind energy and solar energy on seasons and day and light.
If you need us provide a solution, please provide the following information to us:
- Average daily number of Sunlight Peak Hours in every month.
(Peak (Full) sunlight: 1000W/sq.m of energy density). - Average wind speed of at 10m height in every month?
- do you need an air conditioner in your base station?
- does this air conditioner work continuously in 24 hours per day?
- what are your rated power and power consume of your air conditioner?
- what is the average power demand? what is the peak power demand?
- what is the working voltage of the load?
- how many days continuously in your site it is cloudy and without wind?
- is there a man for daily maintenance? or is there a diesel generator for back up?
