SOLAR PV


Everyone is familiar with solar energy, from the wristwatch to a shower system leveraging on such technology.

Technology

Photovoltaics use the internal photoelectric effect to generate electricity from sunlight. Incoming light which is absorbed by a semiconductor crystal releases electrons from their bonding state. An electric field is then required to conduct them away from the solid state.

Solar cells have an n type layer which can emit electrons (emitter) and a p-type layer which can absorb electrons (base). At the boundary interface between the two layers (p-n junction) an electric field us formed, which separates the light-generated charge carriers. A voltage corresponding to the electric field is produced at the terminal contacts of the cell, meaning that current is able to flow as the contracts are connected to each other.

Many types of solar cell have been developed in laboratories to increase efficiency and reduce costs. Five of these are used commercially today and play the role in the market.

 

FAQs

How do I get power at night?

Although your system doesn't produce any electricity at night, a process called net metering allows you to benefit from the day's production. In the morning, your system is producing a little bit of electricity.

How long will a system last?

Most home solar power systems are predicted to last between 25 and 35 years. Sunrun’s agreements last for 20 years. The inverter will need to be replaced in about ten years.

How frequently should I clean my panels?

The solar electricity your panels produce will naturally vary depending mostly on the season and number of daylight hours.
