Solar panels: What to know ?

If you are new in the solar movement this is a good place to start, starting with basic information that can help you answer some questions about solar panels.

Solar photovoltaics (PV) is the technology that is behind solar panels, using a physical and chemical phenomenon to generate electricity from sunlight. Specifically solar panels are made of photovoltaic cells, these are the ones that have electrical characteristics when they are exposed to light. This electricity can be use to power houses, cars or businesses.

The technology has been going around for a long time, but is becoming more popular and is going to grow more in the next years. Singular City is going to give you the most important insights on solar energy.

Photovoltaic cells are becoming cheaper

With the exponential growth of technology and the new developments of solar cells are decreasing their cost really fast. Right now it’s affordable for a wide public and the return on investment is faster. More people are installing solar panels in their houses and they can save a lot of money even in a short amount of time. In some places, you can loan from the government or companies to get the system, so check in your local area.


Solar panels are very durable

Most panels are covered with a warranty by the manufacturers that give 25 years of power production at a certain level of efficiency. They are made of strong materials that can resist wind, rain and can last for a long time with out maintenance.


Connected to the grid, or not

Photovoltaic systems can work with the normal grid connection; this means you can continue using your normal electricity company. Add solar power to produce and use your own electricity, and if you need more energy you can take it from the grid.

You can also opt to be off the grid. This means you can cut your normal electricity supply and use only what you produce. For this system you will need batteries that can store energy when there is no sun. Then there are hybrid systems. In them, you can also store electricity in batteries and if you don’t need it, you can put it back to the grid and earn some money by selling the energy (prices vary depending on the countries’ laws).

Solar panels can be installed almost anywhere

If the sun is out, you can use a PV system. It isn’t necessary to install solar panels on high places. They can be installed on the roof or in the ground; anywhere where they can receive sunlight. Some countries are creating huge solar facilities to generate electricity for their cities and also installing small ones on governments buildings.
