How Does a PV Panel Generate Electricity?

Friday, March 27th, 2015

Solar energy has become a great option for a lot of homeowners thanks to improved technology, rebates and more product availability. However, it’s still a little confusing for the average homeowner to understand how light from the sun can be converted into electricity. It’s obvious that the solar panels achieve this, but the question that remain is “how?” To help you understand better how photovoltaic (PV) solar panels work for your Aberdeen, WA, home, the solar experts from Sunset Air have put together an explanation below that should hopefully shed some light on things.

It All Starts with a Cell

A solar cell, that is. What is it? A solar cell is a relatively small component that has several layers to it: a glass protective cover with anti-reflective coating, a contact grid, a N-type (negative) silicon layer and then a P-type (positive) silicon layer. These all rest on the back contact layer. The N-type layer has free electrons and the P-type layer has holes. When sunlight hits the solar cell, the free electrons are knocked loose from the N-type layer and move into the open holes in the P-Type layer; this action, and the connection of the N and P-Type layers, creates an electrical current.

The Solar Panel

A solar panel, also known as a solar array or PV panel, is a large number of solar cells housed together on a single panel. The electricity generated by each solar cell flows together as the solar cells are all connected to each other by wiring, creating a great deal of electricity. The PV panels are integrated with your home’s electrical panel via wiring and supply the panel with a great deal of extra energy that can be used to power just about any system you want.

Solar energy can be great for a lot of properties, but it’s critical to hire trained experts for installation, repair and maintenance.

3 Advantages of PV Panels in Puyallup

Thursday, January 23rd, 2014

PV panels are a component in solar power. The “PV” stands for “photovoltaics,” which is the method by which solar radiation is converted into energy. PV panels are spread out to catch as much of the sun’s rays as they can in order to transform it into electrical energy. In towns like Puyallup, heating through solar power sounds like a long shot: we’re not exactly inundated with sunny days here in the Pacific Northwest. But PV panels actually make a lot of sense for homeowners interested in solar power. Here are 3 advantages of PV panels in Puyallup, WA:

  • They don’t need sunny days to work. PV panels can pull energy from the daylight even during cloudy or rainy days. That means you don’t have to worry about the sun coming out in order to make effective use of them.
  • They provide increased energy independence. Once you pay for the cost of installation, you’ll find your energy bills going down tremendously as the PV panels begin generating electricity for you. In some cases, you may even be able to sell excess electricity back to the grid. Larger numbers of PV panels mean greater savings, and the existence of PV panels will likely increase the resale value of your house when the time comes. Furthermore, PV panels provide that electricity even when the civic grid is experiencing problems, providing you with greater energy independence than you could expect
  • They’re environmentally friendly.  Solar panels are green to the extreme, generating electricity without an attendant carbon footprint. It generates no harmful byproducts and it requires no fossil fuels. Here in the environmentally conscious Northwest, you can’t do much better.

If you approve of the advantages of PV panels in Puyallup and want to speak to an expert about it, then Sunset Air is waiting to help.
