How do solar street lights work?

Solar street lights are an excellent solution for areas with no access to reliable electricity. They are usually powered by solar panels, which gather energy from the sun and use it to charge a battery, which in turn powers the lights. But if you have a bit of technical know-how, you can build your own solar street lights.

How does a solar cell charge a lithium ion battery?

In the circuit above, the current from the solar cell flows through D1 to charge the Li-ion battery. When there is less sunlight, the higher voltage from the battery cannot flow back to the solar cell. Because there is a D1 blocking it, the current can flow only one way. The energy in the battery is stored and gradually increases until it is full.

How does the NCA decide if a project is ready to be built?

The NCA has the autonomy to issue the permits, stating that a project is ready to be built, without requiring other authorities' approval. Nevertheless, other authorities may submit opinions or inputs to assist the NCA in their decision process. The NCA coordinates the process in which several authorities issue individual binding decisions.

Are pumped storage projects feasible on a smaller scale?

This means such projects are not feasible on smaller scales. The biggest drawback for the overall efficiency of pumped storages is the fact that the water needs to be 'pumped' from the lower reservoir to the upper reservoir for the cycle to be completed. And this part of the cycle consumes electrical energy itself!
