Fundamentals of Solar Electricity Generation

Home solar power systems provide a clean and easy way for the average homeowner to generate the electricity their home needs each day and lower their power bill as a result. If a system is large enough, you can even eliminate your bill completely. In many areas you will also be paid by the local utility for any excess power you generate. These solar DIY systems have become much more efficient and flexible over the years and today provide an almost perfect alternative energy solution.

All of these modern home solar power systems start with a set of solar panels that are typically mounted on the home’s roof. These solar panels are responsible for the actual conversion of sunlight to electricity. Each of these solar panels will generate a lot of power from simple sunlight and the more of them you install, the more power your system can generate each day. There have been dramatic improvements to the amount of power that these solar panels can generate in recent years and current models can produce several times more power from the same amount of sunlight as older versions.

This means that you’ll need less of them on your roof to supply the power your home requires, which can help to significantly lower the cost of the typical system for most homes. It also allows homeowners with limited roof space to take advantage of a home solar power system and lower their monthly power bills as well.

These solar panels produce a DC current from sunlight and this current needs to be converted to AC current before it can be used by your home. This conversion is accomplished through a device called an inverter, which is typically located near your home’s power distribution panel. The inverter performs several different functions and in many ways is the most important link in the home solar power system. In addition to converting the electrical current, the inverter is also responsible for switching your home between the power produced by the solar DIY system during the day and the locally supplied utility power in the evenings.

The other major function the inverter handles is routing any excess power that is produced during the day by the home solar power system, back up the power lines to the local power utility. This solar-generated power will create a credit for the homeowner that can be used later that evening to offset any power that needs to be supplied to the home when the home solar power system is inactive. Most homeowners install a larger system than their home needs so that the excess power generated during the day can completely offset any power they’ll need to buy back from the utility in the evenings. This back and forth trading of power should result in the elimination of a power bill completely, and may even generate a nice income if more solar power is generated than needed.

Solar power systems also allow you to install a bank of batteries with your system to give you even more flexibility with the energy you generate. These batteries can be charged with the excess power created during the day and either saved for use during a power failure, or used in the evenings to extend the power your systems provides before switching over to utility supplied power.
