Key factors to consider before you switch to Solar

Home Solar: How to decide if going green is right for you. |
Every homeowner would be delighted to see their electric bill go away. And for many, solar comes to their minds as a possible answer to this dream. But how can you know if solar is right for you and your home? There are several factors that you should consider that go far beyond just wanting to lower your monthly bill. Let's go over some of them and hopefully help you make an easier choice for your energy plan.
#1. My Electric Bill is Too High!
A high electric bill definitely can make switching to solar tempting, but you'll need to probe deeper than just the numbers. Why is it so high? Are you using inefficient appliances and light bulbs? Leaving things on when you are not home? Believe it or not, the best homes for solar will also be the most efficient homes. Look around and see what kind of light bulbs you are using. You can reduce your monthly electric bills simply by replacing old incandescent bulbs with more efficient compact fluorescents or LED's. A 100W solar panel on your roof couldn't provide enough energy to light two 60-watt bulbs, but could power ten 8-watt LED bulbs with ease. And when you think about how long you are using your home lights, this can add up quite quickly. Since energy is calculated as watts multiplied by hours used, a 60 Watt light bulb lit for one hour uses 60 Watt-hours. With an 8-Watt LED, you could light your room just as bright for over 7 hours before you use the same amount of electricity! When you consider how many light bulbs you have in your house, the savings really add up! All of a sudden, you've reduced the number of solar panels you need on your roof by simply switching out your light bulbs. Now check your large appliances like your refrigerator, oven, microwave, HVAC unit, hot water heater, and washer & dryer. Are they energy star certified? How much electricity are they using? Minimizing your load will help you maximize your benefits from solar.
#2. I have plenty of roof space for panels!
Yes, roof space is definitely a factor, but it doesn't just stop there. Some roofs work better for solar than others, and obstacles like chimneys, vents, lightning rods, pitched windows, and others can cause obstructions that limit your maximum electricity output. And most importantly, the DIRECTION your roof is facing matters. A south facing roof will be your best position for laying solar panels down, while a north facing roof is the absolute worst. So if you have a north/south facing home, don't quickly assume you can just place panels on both sides of the roof! And if you have a home owners association, you will need to check with them if there are any rules or regulations in regards to solar. There are laws that will allow you to place solar even if an HOA says otherwise, but they may have a say-so on which side the panels can be placed, like facing the back yard versus facing the street. And if that happens to be the case and the back side of your roof is north-facing, You may be better off saving your money.

Nearby Trees can be problematic when installing solar panels on your home |
#3. Those trees in my yard shouldn't be a problem
Wow. I've heard this a bunch. The real sentence should say "Those trees in my yard shouldn't be a problem, NOW" Remember, any foliage in your yard is going to grow over time, and since solar is a LONG term investment, you need to consider the long term growth potential of any trees or bushes in your yard. Will they become a problem down the road? Are you ok with cutting them down to make sure your panels get the maximum amount of sun during the day? Are the trees even on your property? Is your neighbor ok with cutting them down? Even with experienced solar installers, this is a common oversight. So keep this in mind and have a good feel for your entire property and the trees surrounding it.
#4. With all the current credits and incentives, solar panels are super cheap!
Yes, but here's a couple things you'll need to understand. The federal and state incentives are in the form of tax CREDITS. Therefore, you will need to have the proper tax liability to retain the credits, otherwise you may end up paying a lot more than you originally had planned. And since they are tax credits and something you will receive in the future, you will still need to pay full price for your solar array upon installation. Some of the tax credits will take up to 5 years to fully recoup, so plan accordingly with your finances.
These are just a few of the basic questions you should ask yourself before installing a solar array on your home. There are many more considerations, especially when it comes to your utility grid, interconnections, and financial modeling considerations that are a bit more advanced. I will cover them in another article soon. Lastly, I want to give you one more piece of advice. Solar is a long term investment. If you are unsure where you might be in a few years, then wait before springing for some panels. It can take several years to recoup all your investment back, so knowing where you will be in the next 5-10 years or even longer will be your greatest factor in knowing if solar is right for you.
