How Many Solar Energy Panels Do I Need to Power My House?
How much solar power to power a house?  That’s the big question on everyone’s mind.

But alas, no 2 homes are exactly the same.  And every customer has slightly different energy needs.  So the answer really depends.

First a little background.

Solar is a scalable technology.  This means you can add as many or as few solar panels as you want.  1 panel will give you a little bit of clean and free electricity.  Adding more and more panels will increase the amount of renewable energy that your property receives.

The only real limitations are rooftop space and land.  If your property is large enough, you can add enough solar capacity to power your entire block or neighborhood.

But How Many Solar Panels Do You Need to Power Your House?

Okay.  So solar is scalable.  But assuming you want to cover all of your electricity needs, how many solar panels do you need for your home?

Again, the answer depends.

How Much Electricity Do You Really Need?

We all have different energy requirements.  And those requirements are often independent of property type and size:

  • Some homeowners live in modest houses but consume a lot of energy on a regular basis.  They need more panels than average in order to cover their electricity needs.
  • Other solar customers live in lavish homes but consume surprisingly little electricity every month.  They can get away with much smaller solar photovoltaic (PV) systems.

As part of your free solar consultation with us, you’ll receive any number of energy efficiency strategies to help you reduce your overall electricity consumption.

Some of these strategies are very simple (like switching out incandescent light bulbs with CFLs).  Others are a bit more involved (like adding insulation or updating older appliances with EnergyStar-approved models).

The more you can reduce your electricity consumption, the fewer panels you need to cover your monthly energy requirements.  This saves you money in installation costs.  And it also reduces your utility bills.

What Solar Components Are You Using?

Another important factor is the quality of your installation.  Not all panels are created equally.  Higher quality solar components deliver more energy per square meter than lower quality ones do.  And thus, you need fewer such panels to cover your electricity needs.

In addition, contracting a licensed and professional installation team will help you generate more power than if you installed the panels yourself.  Click on the following link to learn more about the dangers of DIY solar installations.

On Average, How Much Solar Power to Power a San Diego Home?

There’s a lot of variation out there.  And many different things to think about.  But we can still talk in averages.

Across San Diego County, the average system size is about 5kW.  Keep in mind that this is usually not enough to cover 100% of your electricity needs.  For that, you may have to explore installations in the 8kW to 10kW range.  But 5kW is more than enough to dramatically reduce your monthly electricity bill – often by 50% or more.

This is especially true in California where utility prices are constantly on the rise.  Just last year, some SDG&E customers got hit with 40% price hikes.  Those with solar panels already installed only saw modest increases in their monthly electricity bills.
