Solar Panels Installation Costs
With electricity prices on the rise,

this may be the perfect time to invest in solar energy. The innovations in the field of solar technology have made solar panels affordable and easy to set up for almost anyone who wants to go solar.

You’ve perhaps heard about how solar energy can reduce your electricity bills, but how much does solar power cost to install?

The best way to calculate the average price of a solar power kit for your home is to look at all the costs associated with a complete solar installation and compare them with the potential long-term savings. There are a lot more costs when installing a solar power system than you might think. Solar panels represent just 25 to 30 percent of the total price. In addition to the panels themselves, other operational costs such as permits, connection fees, other hardware components, wiring and mounting have to be considered.

Take some time to understand which is the most optimal system for your needs and what’s the best price you can get on it. With careful planning, you will get the benefits much faster and most likely in a greater proportion.

Here’s what you need to know to help you put the cost in perspective.

Estimating the cost of solar panel installation

When it comes to residential solar panels, the price varies according to the state and the size of the solar system you want to get. Simply put, the more energy you want the system to produce, the more solar equipment you will need to buy.

The good news is that the cost of installing solar panels has dropped drastically in recent years. Most homeowners are paying on average $3.50 per watt to install solar in their homes. The average size of a residential solar system installed in U.S. is 5 kW (5000 watts). At these rates, you should expect to pay around $17,500 (before federal tax credits) to upgrade your house with photovoltaic panels.

Yes, that might seem expensive. But that price tag could go lower by 30 percent or more if you access some of government grants and incentives.

Based on the average $3.50 per watt cost of installing solar panels, the following is a breakdown of the estimated cost of different components that make up a solar power system installation.

I want cheaper solar panels: How to get the lowest price?

Fortunately, there are a couple of great ways to reduce solar panel installation costs. The most attractive incentive is the 30 percent federal investment tax credit, which was just recently extended until 2019. On top of this, states usually offer additional rebates and incentives for installing home solar systems.

To find out which rebates are available in your area, check out the Database of State Incentives for Renewables & Efficiency from North Carolina State University. Don’t be surprised if you’ll find yourself eligible for solar grants that would cut your solar costs by 50 percent.

Dealing with solar providers: Watch out!

When requesting quotes from solar installers you will find yourself with different prices for the same solar kits. That’s because the solar market became very competitive in the past few years. To make sure you get the lowest price possible, don’t settle on your first quote. Get multiple quotes and talk with people who already have solar systems installed in their homes. Learn what are the advantages and disadvantages of going solar, and what steps you’ll need to follow to get one installed. Like any major investment, it pays off to research well before making the commitment.

How much can you save with solar?

Saving money on electricity bills with solar power is definitely the way to go. Even though installing a residential solar power system can be pricey in the beginning, once it starts producing electricity, you will see significant savings with in years rather than decades.

During the last ten years, electricity prices have increased by an average of three percent annual rate. As electricity will continue to become more valuable in the modern world, reducing these costs can help you save a lot of money in the long term. Going solar means you produce your own energy, so you’ll be able to better predict your monthly bills and protect yourself from the rising and fluctuating energy prices.

The typical U.S. home spends more or less $1,200 annually on electricity. That’s about 11,000 kilowatt hours. With a 5kW solar system that will deliver between 350 to 850 kilowatt hours (kWh) per month, you’ll be able to cut your electricity bills in half. That adds up to a savings of around $600 per year, and if you consider tax credits, utility rebates, and net metering, you’re looking at another 20-30% extra savings potential. With a lifetime of 25+ years for a solar system, your savings can easily reach $20,000 during the lifetime of your system.

What about solar prices in the future?

In the year 2000, the whole world had approximately four gigawatts of solar power capacity installed, and it didn’t seem to have a bright future right away. Over the last 17 years the installed solar energy capacity increased by 5,700 percent, reaching 227GW. Now that’s a game changer for solar!

Solar energy is now becoming more affordable all over the world. It is predicted that the price of creating solar power technology will decrease by 4.4 percent every year, meaning that by 2022 the price will decrease by 27 percent. This drop in cost is going to allow more countries to implement solar power as a viable method of delivering energy to their people.
