How to Install a Residential Solar Power System

Comments Off on How to Install a Residential Solar Power System

If you’re considering installing a residential solar power system, it’s important to understand the process before committing to a solar panel installation. You’ll need to know about the net metering regulations, installation costs, and permits. In addition, you’ll want to understand how the utility company will bill you for the energy you produce.

Net metering

The net metering feature on a residential solar power system allows homeowners to sell excess energy back to the power company. The utility pays you for the excess energy you send to the grid, but you don’t pay for that electricity. This can save you money over the course of a year, depending on the amount of electricity produced by your solar power system.

Net metering works by running your electricity meter backward. It means that the electricity your solar power system produces will be credited to your monthly bill. During the day, you won’t be using much energy, but your solar panels are still producing some of that energy. In fact, it’s not uncommon for a residential PV system to produce more energy than your home actually uses. This excess energy will then be fed back into the power grid and help your neighbors meet their energy needs.


The cost of a residential solar power system is based on a number of factors, including the size of the solar array, the size of the inverter, and the peak sunlight hours in your area. The initial quote will also include labor costs, which vary by region. In some cases, the customer can choose to pay for the installation in full up front or choose a power purchase agreement to spread the costs over several years.

The costs of a solar power system vary widely, but an average installation will cost around $2.77 per watt, depending on the size of the system and the location of the solar panels. The size of your solar system depends on how much electricity you use, how much space is available for the panels, and your budget.


If you plan on installing a solar power system on your home, you will need to obtain the necessary permits. These permits can vary depending on the size of your system, the state you live in, and the type of system you’re installing. Some states charge a flat fee for a solar permit; others may charge more than $300. Fortunately, there are ways to lower these costs and avoid paying unnecessary fees.

The first step in the process is contacting your local electric utility. You can find contact information for your utility by visiting their website. Many utilities have easy-to-follow processes for interconnection. In addition, the homeowner or installing contractor must notify the utility when the installation is complete and approved. In some jurisdictions, this is done automatically.


The first step in installing a residential solar power system is to get the necessary permits from your local government. This is called permission to operate and is a safety measure. You will also need to work with your local utility company to connect the solar equipment to your grid. The process can take two to four weeks.

The next step in installing a residential solar power system involves choosing solar panels and solar inverters. You will want to do a little research before you make any decisions. Solar installers will usually recommend the products they believe are the best fit for your property. If you have any questions about the products you choose, you should seek the advice of an electrical engineer. This will ensure that you get the right product for your needs. For more details visit
