RE: Solar streetlights project
What kind of batteries do you plan to built in, is it going to be the Li-Ion by Tesla with that powerwall or are there more suitable solutions out there? If you have 20 lights with 500W and you need power for 6h daily, the battery pack will have the size of an electric car, I imagine.. (200,5KWh6h=60KWh). And will there be a diesel generator in case the sun won't shine for a few days?
The streelights is a set together with the battery. At times the batteries are in build. In case of a rooftop solar system I can decide the type of battery I will use. Li-ion batteries by Tesla is very good one. In sizing of the battery, we have a term called days of autonomy. For example, depending on the customer , I can use 3 days autonomy which means if there is a continuous rain for 3 days there would be supply of energy. 3 days of auntonomy has more battery capacity as compared to 1 day of autonomy. As I said earlier in my post, even if the sky is cloudy still there would be light rays . In case of industries since the demand of energy is high, diesel generator can be added to prevent inconveniences. Solar energy does not pollute the atmosphere. It's environmental friendly unlike fossils fuels (diesel) which pollutes the atmosphere
thanks for the answer. I like the idea of solar energy. In Africa it should be a much bigger thing already. You have soo much sun there^^
Very true. The sun is abundant here. In other to curb the power crisis in Africa we need to focus much on renewable energy
