Each of Japanese Unexamined Patent Application Publication No. 5673633 (JP 5673633 B) discloses a solar system in which power generated by a solar panel is temporarily stored in a power storage device (a solar battery or an auxiliary battery), and when power equal to or greater than a certai.
Will solar power power a public EV charging station?
Clearly a solar array at fueling station in most locations will not produce enough electricity alone to operate a public EV charging station. However, the present disclosure does include renewable energy as a percentage of the charging load. As the technology improves, the percentage of renewable will increase.
In the present application the solar output is used immediately to charge EVs. In the event no EVs are being charged during solar production, the electricity can be stored in a battery for a short period, or put into the transmission grid through a metering program providing a credit.
What is the net effect of solar charging?
The net effect is that if any charging is occurring, all solar production is first used in aggregating the charging load which is then supplemented by storage energy. Energy directly from the grid is used for aggregating the charging load only when the stored energy is depleted.
Should solar panels be placed on recharging stations?
To generate a significant amount of electricity for recharging a number of solar panels would need to be on site. This disclosure proposes placing the solar panels on the station canopies. Most petroleum fueling sites have canopies to protect their customers from the weather.
How many kWh can a solar charging station produce a day?
If a charging station had two level 2 charging sites and two level 3 charging sites, it would be dispensing well over 50 kWh when charging at full capacity. Using present day solar panels on site in direct sun, maximum solar production would be 200-300 kWh daily.
How much electricity does a solar panel produce a year?
Premium solar panels produce about 300 watts per hour. If a site gets 5 hours direct sun daily, solar production would be about 1500 watts or 1.5 kWh. This is about 550 kWh of electricity per year per panel, or about 75,900 kWh annually for the example site of 140 panels.
