kasama na ba ung electric bike ??? o charger lang ....

Hello Po.

Ilang watts po ba ang ebike na ichacharge ng solar ?

Usually 350 watts po ang ebike.

Mukha po kasi mali yung sinasabi nyo sa ads nyo na kapag nacharge ng 10 watts solar ang e-bike ng 4 to 5 hours additional 20 to 30 minutes ang maitatakbo ng ebike.

Let us do the math:

Let say max 5 hours na charge during full sun, that will be total 50 watts.

5 full sunlight x 10 watts = 50 watts.

Yung ipapower na load which is ebike is 350 watts. Which means ebike will consume 350 watts per hour. Kung kukunin natin theoretically ang consumption per minute ng ebike na 350 watts ay 5.83 watts per minute (350w/60 mins.=5.83W).

Compute natin ang additional running time.

Assuming 5 hours nag charge ang solar = 50 watts

Load = 350 watts

Ebike consumption per Minute = 5.83 watts

Additional Running time = 50w divided by 5.83w (50w/5.83w) = 8.57 minutes at hindi 20 to 30 minutes. Masyadong malayo.

The 20 to 30 minutes will be true kung yung solar nyo ay may additional batteries na ipifeed dun sa original battery ng ebike. But the next day the 20 to 30 minutes additinal running time will be much lesser since nagamit na at madadagdag na power lang ay 50 watts.

Check me if I am wrong. Sa tinigin ko you are giving wrong information sa potential buyer.

Peace.

the data is based on our actual testing. The number of hours given was from the solar charger supplier and has been computed by their technical team. Maybe you are right or maybe they are wrong? I don't know. All data are based on actual experience. ty
