Many homeowners feel hesitant about installing residential solar power systems because they’re unsure of what to expect.

How much does going solar cost? What parts do you need in order to go solar? How much of your energy needs can you fulfill with solar power?

Read on for our simple guide to residential solar power systems.

How Much Do Residential Solar Power Systems Cost?

The cost to install a residential solar power system varies based on everything from the size of the system to the region you live in. Generally, the average cost of installation hovers between $12,000 and $15,000. The best way to narrow in on a realistic price point is to get an estimate.

It’s important to note that while the upfront costs may seem high, the savings and tax credits can help. Federal tax credits for using solar power tend to run around $3000 or more.

What are the Different Solar Power System Parts?

Are residential solar power systems large or unsightly? What parts will you need to install in order to go solar?

Rooftop solar power systems are not particularly noticeable. The most visible component is, of course, the solar panels. These are attached to the roof (or another area) using mounting equipment, which may include tracking mounts that allow your solar panels to face the sun throughout the day.

Solar power systems also require a DC-to-AC inverter, utility power meters, and fuse box connections. All residential solar power systems should also include an easy-to-access disconnect switch for emergency use.

How Much Energy Can Your Solar Power System Generate?

The amount of solar power your system can generate will depend on two basic things. The first is how many solar panels you install. The second is how much sunlight those solar panels are able to absorb.

There is a basic formula you can use when deciding how many solar panels you’ll need for your home.

First, calculate the hourly energy usage of your house. Then, multiply that number by the average number of peak sunlight hours your region receives. Then, divide this number by the wattage of the solar panels you intend to install.

In some regions, it may be more realistic to adopt partial solar power. If you do not get a ton of peak sunlight, partial solar power may be the more viable option.

Are You Ready to Go Solar?

Millions of Americans are investing in residential solar power systems. Are you ready to save money on your energy bill and lower your carbon footprint? If so, solar power is the way to go.
