Why Go Solar

What are the advantages of Solar Energy?

Capturing sunlight and converting it to electricity is a clean, pollution-free, efficient, and affordable way to power your home or business. It can increase your home value and lower your electric bills. Best of all, going solar is more affordable than ever with tax credits, solar rebates, net metering programs, and flexible financing options.

How Is Solar Panel Efficiency Calculated?

A solar panel efficiency rating gives you a measure of how much sunlight a solar panel can convert into electricity. Efficiency for different manufacturers and types of panels range from about 12% to over 20%. SunPower is recognized as making the highest efficiency solar panels in the industry, producing 44% more power per panel, and 75% more energy per square foot over 25 years.

Which Direction Is Best For Solar Panels To Face?

Solar panels are most productive when South facing given our location North of the equator. However, anything from due East to just past due West is a productive solar window.

Does It Have To Go On The Front Of My House?

In some cases, yes it does. This is simply based on what your available roof surfaces are.

Do You Have To Penetrate The Roof?

The only non-penetrating roof application is on a standing seam metal roof. On all others we use a very reliable roof flashing made especially for solar mounting systems.

What Roof Material Is Best?

Standing seam metal is probably the best roof material, but we frequently work with composition shingle and have a lot of experience with clay tile.

Do These Things Come With Batteries?

They do not. Off-grid or battery backup solutions are available and your energy consultant will be happy to go over those with you.

How Much Do Solar Panels Cost?

This depends on your utility company, local jurisdictions, your existing electrical service, and the type of panels you choose. Our energy consultants will create a custom proposal for you that includes system size, design, costs, benefits, financing options, and the available federal, state and local incentives such as tax credits and rebates. We will walk you through the proposal during your appointment, which will take place at your home, at our solar design center, or virtually over the phone and online.

Just Tell Me What The Damn Thing Costs!

At a very high level, we can tell you that most of our customers tend to finance their investment and can do so with no money out of pocket and a payment that is often below their energy savings from day one. Our cash customers typically see a payback in 5-12 years, and an IRR that exceeds what the general stock market has historically returned over the last 70 years.

Can I Oversize The System And Sell Back For A Profit?

It depends on if your utility offers such a program – this is something our energy consultants can research for you.

How It Works

Does Solar Work When The Grid Is Down?

Will My HOA Have A Problem With This?

Most HOA’s are super cool about solar. They may have a restriction or two, but the good thing is that Texas passed a law forbidding HOA’s from blocking solar panel installation.

What About Hail?

SunPower solar panels are designed, rated, and tested to withstand hail up to 1 inch in diameter traveling at 54 mph. Moreover, your panels will be covered under your general homeowner’s policy, and if you have a broken panel you will likely need a new roof anyways, so it will all be handled as an insurance claim.


Will My Homeowner’s Insurance Go Up?

In many cases, your homeowner’s insurance will not go up. It depends on how comprehensive your current coverage is. If you need to add coverage, it can cost an extra $10 – $80 per year.

Why Doesn’t My Monitoring Device Match My Utility Bill?

Your utility’s billing period may not start on the first day of the month, so be careful when looking at monthly production or consumption to ensure that you’re comparing the same time period.

The measurements from your monitoring device may not record the exact same totals as the utility meter, as the devices use different methodologies to measure the current. It is normal for there to be a difference within a range of +2.5% to -2.5%, and the meter collects the more accurate reading.

Another important difference for both production and consumption is that the utility can only measure what passes through its meter. The utility will only credit you for excess generation that passes through its meter back to the grid.

Similarly, your utility will only report on energy delivered through its meter to your home. The utility will debit you for the energy you consume from the grid when your energy needs exceed your solar generation (or at night). If you have consumption monitoring installed, your consumption data will be higher than what the utility reports because your solar monitor is reporting all your consumption whether it came from the grid or from your solar array.

If the values are wildly different from each other and cannot be explained by the scenarios above, you may be experiencing one of the following issues:

  • Incorrect configuration of the solar monitor
  • Solar monitor calibration issue
  • Utility meter calibration issue

If you have questions or are concerned about your monitoring, please contact our Service Department.
